With my Notebook, I've lost all Energy options, i.e. the drop
down field is
completely empty and I even can't set new time outs and
consequently no new
Energy options schemes. The PC still behaves according to the
most recent
setting, but I would like to switch between say continuous
mains and
economical battery operation. Content of the remaining tab 2
to 5 is not
troubled, and I prefer and set Hibernate as std shutdown
procedure.
How to restore energy options? Tanks in advance

Before attempting the following procedure you might want to go
to Start -> All Programs -> Accessories -> System Tools ->
System Restore and create a restore point. See the "Create
Restore Points Manually" section of this article for more info.

Once you've created a restore point you can move on to editing
your system's registry to see if it fixes your problem.
Go to Start -> Run and enter regedit.exe in the Open box.
Click OK.
In the right hand pane, click on the + signs to navigate to
this registry key.
HKEY_CURRENT_USER\Control Panel\PowerCfg\PowerPolicies
There should be 6 subkeys under this key numbered 0 through 5.
Those represent the 6 default power schemes that were present
when Windows XP was installed.
You want to leave these subkeys alone right now.
Right click on any subkeys that are numbered greater than 5.
Select Delete from the menu.
Close the registry editor when you've deleted all the extra
power schemes.
Go back to Control Panel and check in Power Options to see if
you have restored the default schemes.
If you've deleted all the extra schemes and you still don't
have the default power schemes download and run the registry
