We have a new HP laptop at work that is our audio recording and video production rig. For some reason today, it would only run on AC and not the battery. The battery indicator in the tray indicated:
Plugged In, Not Charging
Strange for a new laptop to have a bad battery especially when HP Support Assistant indicated a good battery. After some searching, here a possible the fix that worked for me on Windows 7. This probably will not work if you are using a different version of Windows.
- Go into Control Panel
- Go to the System category
- Select View Advanced System Settings
- Go to the Hardware tab and click the Device Manage button
- Under the Batteries section right click on the “Microsoft APCI-Compliant Control Method Battery” and select “Uninstall”
- Agree to the warning to uninstall
- Perform a Windows Update. If you don’t this, your next update will probably break this fix
- Shutdown your computer
- Remove the battery for 1 minute
- Reinstall the battery
- Turn on your computer with your AC adapter since your battery is probably dead
- Windows should automatically recognize the “new” battery hardware and reinstall the driver for you
- Your battery should start charging again
If you have an HP laptop and this does not work for you, there have been reports that certain HP laptops need a firmware update.
