Bleach

i know this must be a trivial problem to you computer experts but i really need help on this one

i accidentally deleted all of the power schemes the laptop had and i dont know how to get them back

the drop down menu where i could select how long before turning off the screen, hd, etc are disabled

i did some research on the net but it involves tweaking the registry or something and i dont want to mess with that kind of stuff (although if someone can give me detailed insructions on how to do the operation id consider performing it)

my laptop is a compaq and doesnt have all the detailed settings possible in the toshibas (toshibas right? cant remember)


thank you guys very much for your help i truly appreciate it
