I figured out how to fix it. Simply reinstall the battery driver through device manager. You can do this by clicking start, right clicking my computer, clicking manage, click device manager, click battery, and uninstall. It will reinstall the driver by itself. I hope it works.

Hi all, just posting this problem in hope of some answers maybe this is a common problem,
I recently installed Windows 7 Pro-Ed, on my HP Pavillion Dv4z-1200 laptop that runs with these specs:
Dual-Core AMD Turion X2 2.1GHz 4G DDR2 250GB.
I cannot seem to edit the power settings to my laptop...
