Your Power plan information isn't available

[Guest]

hello,

Running a dell 1520 notebook. Went in to check on power plan options and
got "Your power plan information isn't available." Tried doing the
troubleshooting but that didn't get me anywhere

What's going on here. Says that some settings, registry keys have been
deleted or corrupted. how to I fix those files or get them back

not a very computer savy person. any help appreciated

Did you ever find out what was wrong here?  I have the same issue...and
it is driving me crazy...

I've been having the same exact problem and could find no information
on any site beyond the basic "here's how you change power plan
settings". Of course this is useless because the whole point is that I
CAN'T change the power plan settings. It turns out that a number of
registry keys, that appear to manage how Power Plans regulate all the
hardware, got corrupted. I exported the key (and all it's sub keys)
from a working machine to a reg file, and then merged it to the
registry of the non-working machine. All of the Power Plan settings
returned.

The registry key is:
HKLM\system\currentcontrolset\control\power\powersettings

I can't speak to what should be the defaults for your particular
system, but if you have another to compare you should be able to do
the same thing.

Hope this helps!
