Doing a Sunday School Projector project at CCCNY, I stumbled upon this problem.
Solution:
Use the command powercfg.exe.
Two other solutions found on the web:
1. Gemarti:
I never actually tried this, but it should work:
Elevate the guest account to administrator. Log on as guest. Make the power option changes and then demote the guest account back to its original state. Just make sure you note what user group Guest was originally in. I have the guest account disabled on my machines, so I don't remember what group it is originally in.
You should be able to promote and demote the guest account logged on as administrator user the lusrmgr.msc snap-in:
START | RUN | LUSRMGR.MSC
2. Dabzov:
Thank you.
I used a different
path, but you led me to the solution. Note - Priviledges for user in
more than one group defaults to group with lowest priviledges.
While logged on a s Administrator:
|start|settings|control panel|administrative tools|computer management|Local users and groups|groups
1. click on "guest" and remove userGuest form groupGuests (apply/OK)
2. Click on "Administrators" and add userGuest to groupAdministrators (apply / OK)
3. Log off Administrator (to save settings)
4. Log onto Guest
5. |Start|Settings|control panel|power options|
6. Change Power Settings|apply|OK|
7. Log off Guest
8. Log onto administrator
9.|start|settings|control panel|administrative tools|computer management|Local users and groups|groups
10. remove userGuest from groupAdministrators
11. Add userGuest to groupGuests
12. log off Administrator
Sorry for the detail, but I will be directing others to this chain of entries.
thnaks again
