You have encountered a problem with the Advanced Configuration & Power Interface, which is a known bug within certain copies of Windows 7.

There are several methods of fixing this problem. The first is to open devmgmt.msc from the Run box and to click "Microsoft ACPI-Complaint Control Method Battery". Right-click it and tell it to uninstall.

Then, power the computer off. Wait for about a minute, then make sure you are working in an environment that does not conduct static electricity. Unplug the computer. Then, pull the battery out of the unit (if a notebook form factor). Turn the computer around, and hold the power button for 45 seconds. When finished, press it normally. Put the battery back in, and plug the computer in.

It is recommended not to go further on some models. While some sources state uninstalling the controller and rebooting does it, I strongly recommend to let the computer charge up, and then power it up when the battery is full. This ensures that the problem will not reiterate for a while. The battery level should register as 100% and the issue should be resolved upon boot.

Glad to help you. If the answer given was helpful to you, please give it a thumbs up. If you have more questions, please feel free to post back.

I think you might have the charger checked by an electrician... it may be on the point of failure (or has failed).

Has the problem started recently ? How old is your notebook ? You might have a battery failure not able to hold charge.

When you take the battery out, your notebook runs on AC power. This is normal, which may also indicate that the charger is O.K..

Is the light on the charger lit up? The charger could have crapped out.... Mine did within the first 3 months.
