I recently had the popular problem of Windows 7 battery manager malfunctioning and not charging my battery when plugged in. The problem was my laptop battery is not charging.
My laptop is new, so the battery is new one, the power supply was fine, and the motherboard was fine. When I remove my supply, I can see laptop battery is discharging, and when I connect power supply back, the battery is quitting from discharge.
I tried couple of solutions before crack down this problem. There are multiple solutions proposed, and here are the steps that fixed it for me. In this solution, we are uninstalling the Microsoft ACPI Compliant Control Method Battery and connecting the laptop back. Please follow the steps in the same order.
- Disconnect AC Power from Laptop
- Shutdown Your laptop
- Remove battery from the laptop.
- Connect AC Power back without battery
- Startup your Windows.
- Right Click My Computer > Properties > Hardware
- Click On Device Manger button
- Click on Battery+ mark to expand it.
- Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall (it’s ok if you only have 1).
- Shutdown your laptop again.
- Disconnect AC Power
- Insert battery to the laptop
- Connect AC Power back
- Startup your laptop.
