Sometimes you may face battery charging issues with your laptop where your battery won’t charge even if the battery is new and the laptop adapter is plugged in to the power socket. It can happen due to many reasons and it is a very frustrating problem for laptop users. So here I am going to discuss the various laptop battery charging issues and provide you the recommended solutions to fix this annoying problem.


Solutions or Fix for Laptop Battery Not Charging

Here I will provide the various solutions and fixes to the battery charging problems in Laptop.

Faulty Adapter / Charger

First of all make sure that your laptop adapter or charger is working or not. Majority of the laptop adapters have a small LED on it and when the adapter is connected to the AC power then this LED glows. If the LED is glowing then in most cases the adapter is OK and getting power from the mains otherwise it has been damaged. But if your laptop does not have an LED indicator then you can check your adapter using a multimeter.

Loose Connector / Pin

If the Laptop adapter is OK then see whether the laptop adapter pin is properly inserted in the laptop power socket or not. If it is connected properly and the battery charging indicator on the laptop is OFF or the battery is not charging then moves to the next mentioned steps.

Faulty / Dead Battery

It may be possible that you battery has gone faulty or it is dead. You can check the faulty battery using a Multimeter or a Battery Tester. There are various videos available on youtube which can show you on how you can test a laptop battery using a multimeter or a battery tester.

Laptop Battery Feature

Some laptop comes with battery saving feature in which your laptop will not charge the battery until the battery percentage drops below 90%. So here do not worry and drop your battery percentage below 90% by removing it from AC mains power and when it drops to below 90% then plug-in in the adapter to the AC power socket and see that if it is charging the battery or not. If your battery and adapter is working fine then the battery will charge normally. This battery charging feature is mostly found in Fujitsu laptops but now more and more laptops are coming with this feature.


Update BIOS

Updating the BIOS may help in some cases to fix the battery charging problem in laptop. So download the latest BIOS from your manufacturer’s website and then update your BIOS. You can refer your laptop manual on how you can safely update or flash your BIOS.

Corrupted ACPI Battery Drivers or Software

It is a very common problem where your Battery ACPI (Advanced Configuration and Power Interface) drivers or Windows power management software gets corrupted, which stops the battery from charging.
