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:

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?
