I just reinstalled Windows 7 Service Pack 1 in my HP laptop. After installing all drivers from HP, I installed HP Power Manager that comes with the factory installation and it broke something with the power managmement options in the system tray.

When I click the battery icon I don't see any plans to select. I have to click on More power options and then change the plan. The original list is empty:

Empty power plans

However the window that appears when clicking More power options actually shows the tree plans.

My question is: how can I "restore" the plans list in the system tray? Why are they hidden in the first place?

Open a command prompt and type the following command:

powercfg -restoredefaultscheme

I own a HP dv6 and the same happened to me ;)

I've reinstalled the laptop over time and never installd HP power management again, I guess your command would solve the problem then... – edgh Apr 22 '12 at 15:59
