Power Schemes missing from Power Options Applet

Hi all, and thanks for helping.

I have a Sony Vaio Laptop PCG-GRX570, using XP Home. Some time ago, for no reason I can fathom, my Power Options Applet stopped offering me the chance to change Power Schemes settings! When I open it, the Power Schemes window is blue and I can't type anything into it, and there are no settings available to choose. I can change the Alarms, Power Meter, Advanced, and Hibernate settings, but can't set any Power Schemes. As a result I can only run full power which as you can guess drains the battery fast. Any ideas to repair this? Can I reinstall the Power Options Applet easily?

Best,
Jim

 

Jim,

I have a Toshiba 6000 and I was not able to use my power schemes until I down loaded the drivers from Toshiba's website. Maybe Sony has this? Try reinstalling the drivers for your labtop. Sorry I can't help you anymore but I did find some info. on a XP Pro. problem almost like yours. Check it out http://www.majorgeeks.com/vb/showthread.php?t=28194
Good Luck.

TK,

Thanks for your help. Unfortunately, the reference site you posted is no longer an active link. So, I'm still without a fix. I tried the Sony site, and no luck so far. Thanks again.

Go to:

Go down to line 204, right hand column, there is an entry for a registry script to restore power schemes

 

Rude,

Thanks for the try. But unfortunately, it didn't work.

I also did try a minimum start-up, basic files, etc. and that didn't make a difference either, so I assume it is not a conflict with some program added later.

Still a mystery.

Best,
Jim
