Power Schemes Have Disappeared

[lazygourmet]

On Acer 4920 with Windows XP Pro, I am barely using the laptop on battery.

But today, after an electricity shortage, it didn't switch on it anymore.

So after a restart I checked power options. Battery showed full but power schemes lists only Desktop and Laptop as choices.

How can I restore the others schemes and recover the use of the battery?

Thanks in advance...

Found this and it might help to solve your problem -

First off, go to Start -> All Programs -> Accessories -> System Tools -> System

Restore and create a restore point before following the procedure outlined

below.

Now, go to Start -> Run and enter regedit.exe in the Open box. Click OK.

In the Registry Editor, click on the + signs in the left hand pane to navigate

to the following location.

HKEY_CURRENT_USER\Control Panel\PowerCfg\PowerPolicies

Under this registry key you should see 6 subkeys numbered 0 through 5. These

represent the default power schemes that come with XP. Any subkeys numbered 6 or

more represent power schemes created by the user. If you find any numbered 6 or

more, right click on each one and select Delete from the menu. In the end you

should only have the subkeys numbered 0 to 5 remaining under the PowerPolicies

registry key.

Do the same for this registry key.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Controls

Folder\PowerCfg\PowerPolicies

If it turns out that this doesn't help with your problem, download and run this

registry fix.
