Hi Jermyn,
It could be that you will need to uninstall and reinstall the power management software which is located in device manager.
Try this:

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 select Uninstall .

WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver!!
On the Device Manager task bar, click 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.

I hope this helps!:)
