My Acer laptop plugged in the battery does not charge
Acer laptops lets you put your work and entertainment on. You can do a demonstration in a long flight, or watch DVD in the center of the park. Acer laptops can do this because they are powered by batteries that allow the laptop to run without having to plug in the power supply. Typically, the battery can be charged by inserting the laptop back to the power outlet. But some problems can prevent battery charging.
Electrical Connection
For laptops to charge, they need to be connected to a power source. Although it may look like you have the cable plugged in correctly on the Acer, make sure that the cord is firmly plugged into the power socket. There should be a light on the Acer keyboard as well as a power symbol on the taskbar for your operating system that tells you whether the laptop is running off electrical or battery power. If it is plugged in, make sure that this icon shows that it is on electrical power. Also check the socket where the Acer is plugged in and make sure that it isn’t turned off at the main circuit breaker.
Battery
Turn the Acer over and make sure that the battery is properly placed in the battery compartment. Most laptops will have locks that keep the battery securely in place. These locks can sometimes come loose. Use a piece of strong tape as a temporary measure to keep a loose battery in place.
Clean the terminals on the Acer as07b51 laptop battery to ensure that there is a good connection. Remove the battery from the battery compartment. Apply rubbing alcohol to a lint-free cloth. Rub this cloth over the shiny metal terminals on the battery.
Over time, batteries lose their ability to be recharged. If neither of the aforementioned steps works, you may just have a bad battery. Check with Acer or other vendors to find a replacement for your model.
BIOS Update
The BIOS (Basic Input Output System) controls a number of basic functions for a computer, such as assigning the hard drives and other system functions. The BIOS also controls the battery charging function. Certain Acer models have a bad BIOS that operates the computer normally but doesn’t charge the battery. To solve this problem, you need to perform an operation called “Flashing the BIOS” where you download a new version of the BIOS and upload it to your Acer. Check on the Acer support site to see whether your computer model could possibly be affected by this.
Adapter
The power adapter, the part that plugs into the Acer from the power socket, can go bad. Check for a power light on the ACER Aspire 5920 Power Adapter. If the light is not lit, you probably have a bad adapter. Replacement adapters can be purchased from Acer or other online vendors.
