Plugged In, Not Charging - Laptop with Windows Vista

I encountered this problem just a while ago when using my new HP Laptop.

When you plugged in the adapter, the battery power remain the same even after a few hours. The problem is not with the battery. The problem lies with the power management software and possibly, it has become corrupt.

So, how do you solve this problem?

You can follow the method listed here http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01174488&lc=en&dlc=en&cc=us&product=3806991&os=2100&rule=6701〈=en

"Uninstalling and reinstalling power management software in Windows Vista

In order to correct problems with the battery's power management software, follow the steps below.

1. Click Start and type device in the search field, then select Device Manager .
2. Expand the Batteries category.
3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and selectUninstall .

   WARNING:

   Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.

4. On the Device Manager taskbar, click Scan for hardware changes .
   Alternately, select Action > Scan for hardware changes .

Windows will scan your computer for hardware that doesn't have drivers installed, and will install the drivers needed to manage your battery's power. The notebook should now indicate that the battery is charging."

There you go. Hopefully this post will help you to solve this problem.
