How Do I Choose The Right Cordless Drill For Me?
Whether you’re looking for a cordless drill that’s straightforward or a drill that’s intricately-designed, the good news is that there is a wide variety of choice on the market. Several of these drills come with built-in features for handling one-of-a-kind jobs.
Assuming, for example, that you do a lot of drilling in hard-to-reach places, you’ll want a cordless drill that is relatively lightweight (five to ten pounds) so you can wield it at wide angles. In addition, you’ll want a drill that features a one-touch work light, so you can see what you’re doing even if you’re in a poorly-lit area or a space that is completely dark.
If you’re drilling into resistant surfaces, you’ll want a cordless drill that features a detachable side handle for stability along with several gears for maximizing torque. If you’re dealing with really difficult surfaces, you may want to seek out a drill that comes with a hammer setting for pumping into the bit as a means of driving deep screws home.
Anyone who operates a cordless drill on a day-to-day basis should pursue a model that comes with two or more batteries. Lithium-ion batteries are the industry standard because they are durable, long-lasting, and because they possess twice the energy of many similarly-sized batteries made from nickel cadmium.
The Myriad Advantages of Owning a Cordless Drill
Let’s start with some basics. Owning a cordless drill means not having to plug in, which enables you to drill anywhere at any time. In addition, the majority of cordless drills are light enough that you can holster them along a tool belt. This allows you to handle simple jobs, like tightening a loose screw on the fly.
Cordless drills conserve electricity by allowing you to drill outdoors or in hard-to-reach places without trailing a chain of extension cords behind them. They are ideal for any workplace in that they eliminate the risk of employees tripping over wires.
Cordless drills have a higher power rating (on average) than their plugged-in counterparts. Most of these drills come with multiple batteries, which means that you can carry a spare and still keep a battery on the charger.
Obviously, a cordless drill is portable enough that you can store it in a trunk or carry it with you on a bike. This might come in handy if you’re a municipal worker or if you happen to be canvassing an area with signs.
Cordless drills are the future, which means that manufacturers tend to place a lot more emphasis on adding features to a cordless drill than they would to a traditional one. A lot of today’s cordless drills are built with progressive features, whereas traditional drills tend to be a lot less advanced.
A Brief History of The Drill
The earliest, most rudimentary drills go back 40,000 years and were based upon the same principle of applying pressure via a rotating point that a modern drill is based on today.
Bow drills (featuring a mechanical bow and a shaft) were invented around 8,000 BCE. Core drills were invented five centuries later by the Ancient Egyptians, and pump drills were invented around 1,000 BCE by the Chinese.
The Ancient Romans are credited with inventing the auger, a crossbar drill that grew to feature a hip-length shaft for boring major holes into a surface. Certain augers were designed with a crossbar wide enough that two men could wind the handle, thereby rendering it easier to penetrate a blunt exterior or solid ground.
An auger eventually evolved to feature the world’s first brace-and-bit system. The brace (in brace-and-bit) referred to a U-shaped handle that made it easier for Roman artisans to crank while boring an attached drill bit down.
Electric motors revolutionized the drill when they were introduced during the 1880’s. The first handheld motorized drill was patented in 1895. It was self-sufficient and capable of completing an extremely taxing job at the touch of a button. Motorized drills opened the door for several other innovations, including the ability to remove an embedded screw via a reverse mode.
Cordless drills were introduced during the 1960’s, with early models being powered via nickel cadmium batteries. Nickel cadmium remained the most efficient power source until lithium-ion batteries came along during the 1980’s.
Three decades forward, and cordless drills continue to evolve. A lot of today’s models come with innovative features including hammer action, high-powered torque, and an auto-fitting barrel for securing bits inside the jaw.

In our full review, we call DELL XPS 15, “the best 15 inch Laptop, and money to buy.”.” There is also the same infinityedge panel for 13 inch brothers, a beautiful and powerful graphics display. It’s also a good value. The equally configured 15 inch MacBook Pro and AMD video cards cost more than $650.
Then again, the XPS 15 has a couple of quirks that may make some think twice. So is it right for you? Here’s a look at the XPS 15’s pros and cons.
The Dell XPS 15 we tested had a brilliant 4K touch screen, though you can also opt for a 1080p non-touch option if you prefer your displays a little less glossy. Our test version covered a very impressive 188 percent of the sRGB color gamut and measured a bright 282 nits.
To make it better, the display has almost no bezel, thanks to Dell’s InfinityEdge technology, so the screen is practically floating in the air. It looks great.
The XPS 15 is a performance powerhouse, thanks to its GTX 1050 GPU. While many laptop makers are still including 940MX cards, Dell tossed in a Pascal GPU. It’s great for creative professionals and even for some low-level gaming. The laptop handily beat competitors like the HP Spectre x360 and MSI PE60 Prestige in benchmark tests.
On the Laptop Mag Dell Xps m1530 Battery Test, a specced-out version of the XPS 15 lasted for 8 hours and 23 minutes of continuous web browsing over Wi-Fi, which is longer than average. That’s despite a 4K display and a GTX 1050 GPU inside. Dim the display or get the 1080p version and you should expect even more endurance.
If you’re listening to music or watching movies on the XPS 15, the speakers will make you proud. In our testing, we found the sound to be loud and clear, and options within the Waves MaxxAudio Pro app helped us tease out the bass, which was initially missing.
The carbon-fiber finish on the deck of the XPS 15 is softer to the touch than the cold and hard aluminum you’ll find on other laptops. This treatment makes for a comfier typing experience on your wrists.
Every configuration of the XPS 15 comes with a Killer Networking Wi-Fi card. It’s known in gaming circles for stronger, faster connections, but you’ll find it just as reliable in your day-to-day browsing.
The thin bezel means there’s no where to place the webcam on top of the display. Despite a few years of InfinityEdge displays, Dell hasn’t come up with a better place to put the webcam than under the screen so that it looks right up your nostrils. It’s better than nothing, but both you and anyone you video chat with is going to notice.
Don’t Get the Starting Configuration
While the XPS 15 starts at $999.99, that’s for a model with a Core i3 CPU, 500GB hard drive and 32GB SSD. I
To meet the specs we recommend, you’ll want to go for the $1,349.99 configuration with a Core i5 CPU, 8GB of RAM and a 256GB PCIe SSD. This one comes with a GTX 1050 graphics card.
Want a 4K display? That will run you $1,749.99.

SAN FRANCISCO — A start-up company is trying to strengthen the battery type, has been a simple device, such as flashlights and toy subjects, but until now has been overlooked as an energy source, computers and electric vehicles.
Executives at Ionic Materials, in Woburn, Mass., plan to announce on Thursday a design breakthrough that could make solid-state alkaline batteries a viable alternative to lithium-ion and other high-energy storage technologies.
Alkaline batteries can be made far more cheaply and safely than today’s lithium-ion batteries, but they are not rechargeable. That issue, along with the superior power of lithium-ion batteries, has meant that alkaline batteries are not used in personal computers, smartphones or electric vehicles.
Ionic could change that equation with an alkaline battery the company said could be recharged hundreds of times. One additional benefit of the company’s breakthrough: An alkaline battery would not be as prone to the combustion issues that have plagued lithium-ion batteries in a range of products, most notably some Samsung smartphones.
Cheaper and more powerful Dell inspiron 1520 laptop batteries are also considered by many to be the driver needed to make the cost of renewable energy technologies like wind and solar competitive with the coal, gas and nuclear power that support the national energy grid.
Ionic said it had developed prototypes of a rechargeable alkaline battery that can be made using continuous manufacturing processes similar to the making of plastic wrap. So far, the company, which is backed by William Joy, a pioneering Silicon Valley computer designer, has demonstrated up to 400 recharge cycles for its prototypes. Ionic executives say they believe they will be able to triple that.
The alkaline batteries that Ionic has developed would initially be heavier than today’s lithium-ion batteries, said Mike Zimmerman, a materials scientist who is the founder and chief executive of Ionic. But the new batteries would more than compensate for that handicap with their cost advantage and, in time, their ability to store more energy.
There are other advantages besides cost and safety. Lithium-ion batteries rely on cobalt, and using that element comes with a human cost. Cobalt mines in Africa, for example, have been accused of using child labor while leaving behind a toxic mess.
Alkaline batteries, on the other hand, use relatively abundant zinc and manganese. “Ionic can help us get lithium-ion past cobalt and completely eliminate it with alkaline,” said Mr. Joy, who is a member of Ionic’s board.
He also said that the company had made progress toward an alkaline battery design that would replace zinc with more affordable aluminum. In the past, aluminum has not been usable because of issues like corrosion. Alkaline batteries based on aluminum would potentially weigh less than lithium-ion batteries and would be even cheaper to produce than today’s alkaline designs.
Ionic will make its announcement in Colorado at a conference for the 35th anniversary of the Rocky Mountain Institute, a sustainable-energy research group founded by the physicist and environmentalist Amory Lovins and Hunter Lovins, his former wife.
“They started with a very sensible set of criteria,” Dr. Lovins said of Ionic. “They use an unusual electrolyte to come up with a battery that uses common cheap materials and is benign.”
But he added a note of caution: “Batteries are very difficult and I want to see what they have and what can be measured and proven and whether it will get to market.”
Technological progress in battery technology has been glacial compared with the exponential advances in processing speed and data storage capacity that have been staples of Silicon Valley’s growth. In the last 150 years, only a handful of rechargeable battery chemistries have reached mass adoption.
Tesla, in partnership with Panasonic, is building a factory in Nevada with the intent of greatly expanding capacity to make lithium-ion batteries and lower production costs. Tesla officials said they wanted to create enough capacity to produce batteries for 1.5 million cars a year.
There is growing interest in pursuing such so-called solid-state battery technologies for both consumer and transportation applications. Last fall, the United States Department of Energy’s agency for supporting research in next-generation energy technology announced 16 research awards aimed at accelerating development of solid battery technologies, including a $3 million contract to Ionic Materials. The company said it had signed several licensing deals to produce commercial versions of its design, but it would not identify its partners.
The United States Advanced Battery Consortium, an auto industry group, wants to greatly reduce the cost of lithium-ion production. Analysts, however, say they believe the new facilities and technology from auto and Dell r795x notebook battery manufacturers will help bring costs down, but still fall short of industry goals.
In contrast, Ionic executives said they had found a way to achieve energy production costs that would be less than a fifth of the auto consortium’s target.
Bloomberg New Energy Finance, an energy research group, has forecast that mass-market adoption of electric vehicles will not occur until operating costs fall to match those of internal combustion engines. That is expected to happen in 2025, according to the group.
In December, Ionic Materials also described a solid material it said would improve the safety of existing lithium-ion batteries. The company has demonstrated the batteries’ resistance to catching fire or exploding by driving nails through them and even shooting them with bullets.

Is your laptop running slow? Whether it’s new or old, Windows, PC, or laptop, using a slow laptop isn’t a pleasant experience.
If you’re looking for ways to make your laptop run faster by upgrading it with faster storage and RAM, or by removing items that could be slowing you down, such as malware, viruses, and even anti-virus apps, or you just want to streamline your laptop for optimum performance, then this is the place to start.
We’ve gathered six laptop performance-related tips that can breathe new life into your old laptop, or make your new one really take off:
- Malware slowing things down.
- Precious resources being used by open apps.
- Too many startup items.
- Limited free space on your startup drive.
- Visual gimmicks slowing down your computer.
Malware, Virus, and Anti-Virus
Whether it’s adware, spyware, or a virus, malware can be a leading cause of computer slowdowns.
Although viruses, adware, Trojans, and spyware all have unique elements that classify them, we’re going to consider them all under the malware umbrella, as evil demon spawn we don’t want to see on our laptops. No matter what type of laptop you have, Windows, Mac, or Linux, you should consider some form of anti-malware app as a first line of defense.
For Windows and Linux users, active anti-malware apps that can scan your laptop, both in the background and on demand, are a good choice.
For Mac users, the on-demand malware scanner may currently be a better choice since it doesn’t take up resources except when it’s in use.
But don’t get carried away; a single anti-malware scanner is sufficient defense. Running more than one at any one time is more likely to lead to a slow, unresponsive computer than it is to find additional malware.
To get started removing malware from your Windows laptop, look at How to Remove Adware and Spyware.
Mac users may find Malwarebytes Anti-Malware for Mac a good resource for both scanning for malware and obtaining information on how to remove most Mac malware. By the way, Malwarebytes is also a leading anti-virus maker for Windows.
Too Many Apps Open
Do you really need all those apps running? A common cause of laptop slowdown is the sheer number of apps that are active. Each app eats up laptop resources, including RAM, disk space (in the form of temporary files that are created), and CPU and GPU performance. And while apps running in the background may be out of sight, they still consume some of your laptop’s limited resources.
But it’s not just the number of open apps, but how you’re using an app. A good example is your web browser. How many tabs do you have open? Most web browsers use a sandboxing technique to isolate each open window and tab from the others. This means you can consider each open browser tab or window as if it were an open individual browser app. See how quickly the number of “open apps” increases, and the effect it has on your laptop resources? Getting in the habit of closing unused apps, and only opening the ones you need, is a good way to help manage resources and your laptop’s performance.
- Quit apps when you are done using them
- Close browser tabs that you no longer need
Control Start Up Items
You should also consider preventing apps from starting automatically. All of the major operating systems allow you to configure apps so they’ll start up automatically when you boot your computer. These can save you time by not having to remember to start up certain apps, but we often forget to remove even if we’re no longer using the app. If nothing else, it’s a good idea to take a look at what’s starting up.
- Mac users: Remove Login Items You Don’t Need
- Windows users: Use these instructions to Prevent Programs Loading at Windows Startup
Free Up Disk Space
If there isn’t enough free space on your startup drive, you force the laptop to work harder at finding the space needed to house temporary files used by the system, and by apps (another reason to limit the number of apps). The system also sets aside disk space for virtual memory, a way for the operating system to squeeze out additional RAM space by moving older data from RAM to the slower disk.
When space gets tight, your laptop can slow down as the overhead for the operating system increases as it tries to manage these storage tasks. You can ease the overhead by ensuring your laptop always has plenty of free space.
As a general guideline, keeping a minimum of 10 to 15 percent of the space free should ensure that your laptop won’t experience a dramatic slowdown due to storage issues. Even better, you can ensure you won’t have any storage problems at all by keeping 25 percent or more free space available for the operating system to use as it sees fit.
Windows includes a handy built-in utility for helping with disk cleanup. Take a look at: Free Hard Drive Space with Disk Cleanup.
If you need help with a major disk cleanup, check out the 10 Free Disk Space Analyzer Tools.
Mac users will find additional information available in How Much Free Drive Space Do I Need on my Mac? There are also a number of tools at your disposal, including DaisyDisk.
Should you defrag your disks? In general, no. Both Mac and Windows laptops are able to defrag drive space on the fly as long as enough free space is available. Of course, you may have specific needs for defragging, depending on the type of use you put your laptop to. Just remember: never defrag an SSD.
- Keep plenty of free space on your startup drive
- Defragging a drive may not be needed
Cut Down on Visual Effects
If you have a new laptop with the latest and greatest CPU and GPU, you may not need to cut back on some of the inane visual effects that both the Mac and Windows operating systems seem to like to throw in our faces.
But even if you don’t need to, you may still want to. Eliminating some of the OS visual effects can help increase overall performance by ensuring the CPU and GPU aren’t busy with useless eye candy when you need productive use of the processors.
Mac users will find many of the visual effects are managed in various system preference panes, such as the Dock and Accessibility.
Windows has its own system properties settings that affect performance. You can learn how to access and control the visual properties in the guide: Adjusting Visual Effects to Improve PC Speed.
In most cases, toning down the visual effects will produce a much more responsive user interface, and keep resources available for apps that need them.
- Reduce graphic eye candy to a minimum
Upgrade RAM, Disk, Graphics, and Battery
So far, we’ve talked about managing performance by keeping fewer apps open, increasing the amount of free space on your startup disk by removing files, and generally managing your laptop’s resources.
But what if you have an app that would be a better performer if it had a lot more RAM or disk space, or a top-of-the-line GPU to work with? Or perhaps you would just get a lot more done on your laptop if it could run longer on a charge.
Depending on the laptop model, you may be able to increase overall performance by upping the amount of RAM installed, switching to a faster or larger (or both) disk, upgrading a CPU or GPU, or even just replacing the Dell latitude d620 laptop battery, to gain some additional runtime.
These kinds of upgrades can bring significant performance improvements, usually at a lower cost than replacing a laptop. To find out of you can upgrade your laptop, check with the manufacturer, and then shop around for the best upgrade prices on components.
- More RAM equals more space for apps to run
- Speedier drive allows apps to open and work faster
- Graphic intensive apps can perform better with an upgraded graphics engine
- Replacing an old laptop battery can increase run times.
Keep Up to Date
Last but by no means least, keeping your OS current can alleviate slowdowns caused by bugs; it also helps by replacing system files that may have become corrupt over time. The same is true for your apps.
Use Windows Update to keep current, or the Mac App Store to update your Mac.
- Keep your operating system and apps current. If you are comfortable with it, many systems and apps offer automatic updating so you don’t even have to remember to do anything in order to stay up to date.

Checking the health of the battery is one of the most important and the least important things that we all know. The battery in a laptop is a key component that can continue to power when it is not plugged in. Therefore, it is important that people realize the change in the battery capacity over time and its wear and tear because of any kind of heavy use. On the contrary, however, the health status of laptop computers is often not as good as is known. It is a tendency to assume that the battery works as it should and when a person realizes that it cannot hold the charges for a long time, it must be replaced.
This is where some third party tools can come in handy. These tools help you in analyzing your TOSHIBA PA3757U-1BRS Laptop Battery life by extracting the extra information that your battery has to offer. Thus you can get the maximum output from your battery simultaneously increasing the overall battery lifetime. Here is a compilation of some of the best battery tracker utilities for your laptop to help you maintain a healthy battery.
How to Test Battery Capacity using the Laptop Battery Calibration Software
#1. BatteryInfoView
BatteryInfoView is quite a straightforward tool in a lightweight package that displays the status and information values offered by your laptop battery. There are around 20 different values that can be displayed but the attributes that are shown depends on what inputs your battery can provide that is how many of these are available. Details as shown in the image above such as the manufacturer and model information, power state, charge and wear capacities, charge/discharge rates, temperature etc. can be displayed and these values are updated every 10 seconds.
Apart from the main battery information window, the log window appears on pressing F8 key. The log window gets updated every 30 seconds and gives you a fair idea about what the battery has been doing. These statistics are tracked frequently and can be exported as a text file in case you need a record of your battery’s performance. BatteryInfoView is compatible with Windows 2000 and above.
#2. BatteryBar
This utility displays less information in terms of numbers than BatteryInfoView but way more than the battery icon on the tool bar. BatteryBar is a slightly larger battery icon – but click on it and a pop-up status window appears that offers valuable information such as charge percent, capacity, charge/discharge rate, charge time left and the level at which your battery is already worn out.
The battery graphic color depends on its status, blue means it’s on A/C power and charging, green is a high charge, yellow is medium and red is critical battery remaining.
The .NET Framework v2 is a prerequisite to run the program and once installed you just need to right click on the task bar -> Toolbars -> BatteryBar. This will show the battery status graphic on your task bar.
BatteryBar can be used by Windows XP and other higher versions.

Comments Off on A Definitive List of 5 Tools to Check Battery Health of your Notebook
You can never be too rich, too healthy, or too much battery life for your laptop. And you have to buy a notebook and get great stamina out of the box. You should try your best to squeeze as much time from your system as possible. Forum user EvilHamster wants to help find a program that provides a detailed power report that he or she can change settings or activities to improve battery life.
Windows Energy Report
Fortunately there are several ways to tell what hardware and software are using the most power in Windows. From version 7 on, Windows has a built-in report that measures energy consumption.
To generate this report, you simply run the command prompt as an administrator and type powercfg -energy and then press Enter. The software will then take 60 seconds to do its work and, when it finishes, you’ll have an HTML file called energy-report.html and it will be located in the C:\Windows\system32\ directory.
Open energy-report.html in your browser and look through it to find programs that are using a lot of CPU resources and therefore draining power. When I created the report on my computer, Chrome browser showed up as the top resource hog. Considering that I was using Chrome with over a dozen tabs open when I ran the program, this isn’t surprising.
Using HWinfo to Track Power Usage
HWinfo provides a different way to measure power consumption. Once you download, install and launch it, make sure your laptop is unplugged and click the Sensors button. You can then scroll through the real-time report which shows several fields that detail the energy use of your CPU some other components, but sadly not the screen.
The best field to look at is the Hp 484170-001 laptop battery charge rate, which is a negative number of watts. Clearly, the lower that number of discharging watts, the better for your battery life. So try lowering your screen brightness, closing apps or even changing your power profile to see what lowers the discharge rate.
Whether you closely monitor your power consumption or not, here are a few tips that will help you increase your laptop’s battery life:
- Turn down screen brightness: Your screen is one of the most energy-hungry components in your laptop and the one you can most easily control. The dimmer you make it, the less power it gulps.
- Connect to 802.11ac Wi-Fi: In our lab, we’ve found that running our web surfing battery test on a 5-GHz, 802.11ac router results in one to two hours more battery life than connecting over 802.11n.
- Limit background processes: Don’t let anything run in the background that you don’t need right now. Only use Skype once in a while? Don’t let it run all the time. In Windows 7 and 8, you can see a list of all the apps that start when Windows starts, by opening msconfig (type msconfig in the Start Menu) and going to the system tab. In Windows 10, you can get there from the Task Manager.
- Select the Power Saver profile: Change your power profile by right clicking on the HP 593554-001 notebook battery icon in the system tray and selection Power options.
- Put it to sleep: If you are already on a low-power plan, you can probably skip this one. Check your power profile to make sure your laptop goes to sleep after 5 or 10 minutes of inactivity so, when you step away for more than a few minutes, your computer won’t use up its juice.

Whether you’re a big eyed freshman or a secular senior, you need a decent laptop to get you through school. But given the ridiculous cost of tuition these days, most students do not have a strong income. Fortunately, there are more options than ever. Google’s Chromebooks, due to its low price and long battery life, is the real storm in the budget laptop scene.
Chromebooks stand as an affordable option for college students, costing anywhere from $200 to $400, but are they worth the money? If you spend most of your time browsing the web, scrolling through Facebook and the like, then yes. These cheap machines are ideal for light-usage, which is why they’ve made such a dent in the education market. They’re also at lower risk for security snafus because they exclusively run web-based applications.
If you just want to know which one’s the best, it’s the Asus Chromebook Flip. It boasts nine hours of Asus a32-k52 laptop battery life, a lightweight form factor, a very classy design, and speedy performance—basically, it checks all the right boxes. However, we went hands-on with a slew of Chromebooks: from versatile 2-in-1s to Android-based ‘books, we checked out performance, build quality, and everything else. Everything on this list has something to offer buyers. These are the best right now.
Asus Chromebook Flip C302CA
Best Overall
This Asus is one of the swankiest Chromebooks I’ve ever seen. Between the thin profile and silver shell, it looks suspiciously like the MacBook. Is it a coincidence, I wonder? The posh design is cool and all, but let’s discuss the guts.
The Chromebook Flip earned a score of 367.79 in Basemark, which is a web-based application that evaluates performance. That’s serious power. We weren’t too surprised by that result, though. Our review unit had an Intel Core m3-6Y30 processor and 4GB RAM, a step-up from the usual Chromebook fare. We also discovered that the machine can handle up to fifteen open tabs at once. Multitaskers, get in line.
The superb 1080p display deserves its own call-out, too. It provides really crisp images. When I watched gameplay footage for The Legend of Zelda: Breath of the Wild, the rolling hills of Hyrule were so vividly green. The colors are rich and lovely, and I wasn’t disappointed.
The only downside is the cost. Most Chromebooks fall in the range of $199-$250, with $300 being the sweet spot. If you’re able to shell out the money, I’d spring for it. Chromebooks are evolving faster than ever, especially this new wave of 2-in-1’s.
Acer Chromebook 11 N7 C731T-C42N
If you’re a bonafide klutz (like me), this durable Acer might be the laptop for you. I can’t tell you how many times I’ve doused my keyboard in tea or water over the years, and if I’d had this one, it wouldn’t have been an issue. This Acer delivers a military-grade chassis and unique “gutter” system, so it’s pretty tough. Between the durable shell and water resistance, it’s basically klutz-proof.
Acer’s gutter system drains spilled fluids out of the bottom of the Chromebook, so naturally I had to try it out. I’m not sure what I expected, but this Acer continued to function after I purposefully dumped water into the keyboard.
But what surprised us most was the fantastic Acer as07b41 notebook battery life. When we put this Acer through our browsing test—which continuously cycles through popular websites like Twitch and Facebook—it lasted a total of eight hours. That’s more than a full school day.
The Acer had a couple of drawbacks, though. It doesn’t run Android apps, meaning you’re at the mercy of the Google gods. In other words, you’re missing out on a whole lot of games and utilities.
The other drawback was the poor performance. It’s snappy enough when viewing videos or chatting in Slack, but it struggles with more than seven open tabs. So, if you’re the type of person who likes to multitask, you might want to keep tabs on your tabs. Still, it’s a good laptop for the low price, especially for an accident-prone middle school student.
Samsung Chromebook Plus
Like the Asus Chromebook Flip, this 2-in-1 has an eye-catching design. Unlike most Chromebooks, which are pretty nondescript, this one has a bit of flair to it. Made of magnesium alloy, it looks and feels like a premium machine, and the monochrome Google Chrome logo really pops against the silver lid. The body is also sleek and lightweight, but has a little give.
The 1600p display is top-notch, too. When I watched the Ready Player One trailer, the deep purples of the fantastical worlds inside OASIS, a video game, were sharp and vivid. There’s a glossy finish, though, so you’re going to be dealing with some reflection in brighter environments. The reflection is especially noticeable when the Samsung is in tablet mode.
The battery life was disappointing, but not surprising, as the high resolution touchscreen display is a big power suck. The Samsung fizzled out in about five hours, which is below-average for a Chromebook. You’re going to want to keep the power adapter nearby.
For a Chromebook, the Samsung is expensive. You’re getting an excellent display, but the price is a little steep. If you’re working with a flexible budget and plan on using the machine for casual use, I’d say go for it.
Lenovo Flex 11 Chromebook
There’s no point in beating around the bush here. The Lenovo Flex is one ugly machine. It has the modern 2-in-1 design, which is nice, but it looks like one of those bulky business laptops from the early 2000’s. Between the ultra-thick bezels and dark grey exterior, it’s super plain. But Chromebooks aren’t known for their beautiful designs, and at least it’s plenty rugged.
Like the Acer, this Lenovo has a spill-resistant keyboard/trackpad; overall, it’s very durable. There’s a 5 mm rubber ring surrounding the machine, protecting it from unexpected bumps and shocks. So, ideally, this laptop should survive all but the most severe tantrums. There’s a trade-off for all that protection, though: For an 11-inch Chromebook, this Lenovo is seriously bulky. I didn’t mind lugging it about, but hauling a three-pound Chromebook every day isn’t really ideal, either.
Dell Chromebook 3189 2-in-1 (4GB RAM, 32GB Storage)
The Dell is another unassuming-looking 2-in-1 that bends back into tablet and tent modes. While it’s not the lightest or most attractive Chromebook we’ve seen, it’s sturdy enough for K-12 education environments. The plastic lid is scratch-resistant, the keyboard is sealed against fluids, and the rounded edges are rubberized. The design is a bit utilitarian, but that seems to be the norm for Chromebooks.
The full-sized keyboard offers a great typing experience. Most Chromebook keyboards feel tiny and cramped, but not the Dell. The keys feel firm under my fingertips and there’s plenty of space between them. I didn’t notice any creaking of the chassis either, so it appears to be well-built. I clicked my way to 76 words per minute, too, which is close to my average of 80 (wpm).
It’s not the kind of machine that screams luxury. It’s the kind of machine that favors practicality over luxury. This Dell might be a good laptop for a college student on a budget.
