How to troubleshoot non recharging DELL Inspiron 1545 battery failure

See if the Dell Inspiron 1545 Laptop AC Adapter is damaged or not. Remove the battery power from your notebook and switch on the laptop or computer using the energy plug connected. If your Inspiron notebook doesn’t switch on, use an additional energy adapter to confirm whether your first one is malfunctioning. If your second trial doesn’t work too, the problem may be the power circuit on the motherboard. Search for a licensed PC technician to help you solve the problem.

Try another battery. If your Dell 1545 laptop or computer does switch on and your power adapter is in great condition and not the reason for the problem, try putting another Dell Inspiron 1545 Battery in. You must use one that fits the technical specs of the notebook, to make it suitable for testing. If the second battery is useful, it is probably that the first one is actually malfunctioning.

See whether the issue is the result of a software program. If your laptop battery condition isn’t being shown properly though a software program, it may be that the program is causing the problem and not the electric battery.

Energy reset the system by disconnecting it and detaching the battery. Right after carrying out that, hold that power key down for 60 seconds. After that, connect the Dell electric battery and energy adapter, and launch the notebook again. This might fix the particular charging failure of your battery pack.

Recalibrate the battery. When the Dell Inspiron Battery ceases charging each time the charge sign gets to 96-98%, your notebook should be recalibrated for a fresh battery. For suitable laptop recalibration, the Windows energy management ought to be set up to stop the device from going into sleep mode or hibernation once the battery pack gets to a very low level. If you carry out this out procedure, exhaust the battery completely until the Dell 1545 laptop system turns off. Once discharged completely, place the adapter into the energy jack and allow it to charge entirely. At times the cycle should be repeated 2-3 times just before it really gets to the 100% complete charge. The actual charging procedure ought to last at a minimum around fourteen hours.

Note that the connector coming from the PSU has actually three pins: outer sleeve (0v), inner sleeve (20v) and center pin (5v). Without the 5v on the center pin, the computer works but the battery won’t charge.

If your computer works when connected to the power supply but the battery won’t charge, use a multimeter to measure the voltage on the center pin, being careful not to short it with the 20v inner sleeve (use a short piece of a plastic straw to act as an intermediate insulator sleeve). If it shows 5v, the problem is something else. If it shows much less than 5v, this might be the problem.

Disconnect the power supply from the wall. Cut the insulator plastic which covers your connector using a sharp object such as an Exacto knife, being careful not to cut very deep or you’ll damage the wires.
