Power Option Problem

I am running XP Pro with SP/3 and have lost my power option function. Everything under "Power Schemes" is grayed out so I have no setup options..
Can anyone help, I've not seen this problem before.

Thanks,
Reid

Try #204 right column.

These are automatic registry edits/changes so backup the registry first.
I used the 1 mentioned for the same problem - worked.

 

This worked perfectly, but why should you back up the registry and how do you do this?

I also have a problem with using the "toggle keys" and "sound sentry ". I use this feature to flash the screen and beep when you accidently hit the "caps lock" button. I can put a check mark in "toggle keys" and it will beep but very lowly, almost to the point of not hearing the sound, there should be a way to increase the PC volume, this sound does not go through the external speakers. I then click on the sound tab and put a checkmark in "soundsentry" then a drop down gives you the option of having the "screen flash ", the "caption bar flash" or the "desk top flash ". The option I always use is to have the "screen flash" but I can no longer get this to function, neither can I get the "desk top" to flash, the only option that works is I am able to get the "caption bar flash" function to operate.

Any ideas on how to straighten this out?


Thanks,
Reid
