Laptop battery start wearing off after about 1 to 2 years of usage. Many of these batteries suffer reduced backup and charging problems. I have an HP Pavilion laptop which I bought 1.5 years ago and the battery performance has considerably gone down with time. Sometimes I face battery charging related problems also which can be because of two reasons.
In this post I will discuss both the reasons and share the solutions.
Laptop Battery Not Charging Because Of Heating Issue
First problem which is there with some of the HP laptops is the battery charging stops when the laptop heats up. This is a weird problem, but the HP service center guy told me that the battery sensor malfunctions if it gets too hot and the charging stops. With old laptops with heating issues, this problem is very common. The work-around for this problem is to keep running on mains power or switch off the laptop for sometime to allow it to cool off.
A better solution to this problem is to get the laptop services and remove the heating problem by getting the cooling ducts clean. Also there may be heat sink related problems which cause excessive heating. After the heating problem is resolved, the battery charging will become normal.
Laptop Battery Not Charging Because Of Battery Device Driver Issues
There are some default battery device drivers which are bundles in Windows 7, these drivers try to control the battery charging properly, but for some laptops, these drivers may not function well. In such cases, users face problems like Laptop battery does not charge even when the battery is low and power adaptor is properly plugged into the laptop. In such cases, its better to download compatible battery drivers from manufacturer and install them instead of the Windows default drivers. [ via Raymond.cc ]
To un-install the default drivers, press Windows + R together to to open the RUN prompt. Type “devmgmt.msc” and press enter. This will open device manager.
On Device Manager, browser to Batteries > Microsoft ACPI-Compliant Control Method Battery , right click on it and click “Uninstall”. After this restart the laptop and the battery charging should start.
Hope you find the method easy to follow.
