Hi,
First of all, shut down the notebook, unplug the AC Adapter, remove the battery, and then hold down the Power button for 30 seconds.
Now, plug in the AC Adapter without the battery inserted, start the notebook, open windows Control Panel, open Device Manager, expand the entry for Batteries, right click on and the Microsoft ACPI Compliant Control Method Battery and select Uninstall - do not uninstall anything else here. When the uninstall is complete, shut the notebook down, unplug the AC Adapter, re-insert the battery and then start the notebook on just the battery. Windows will automatically reinstall the driver - leave Windows running for a few minutes. Shut down the notebook again. Now plug in the AC Adapter ( with the battery still inserted ) and start the notebook to see if this has helped the issue at all.
Regards,
