Power Management with User Account

Question

On my T43p, I have the newest power management version installed and XP SP3. In the power management, I cannot change power profiles from within a user account. I can however change the power profile in the Windows control panel (this only after I changed the power policy registry keys). Is there a way to make power management do this?

Hi,
I have discovered a workaround to this problem, but it's not a definitive solution. When you log in as a 'not administrator' user, you have to use the 'Run As' command of WinXP on the file (right button mouse click on it):
"C:\Program Files\TOSHIBA\Power Management\CePMTray.exe"
And then, you have to insert username and password of an administrator user. You have to do the same thing to the
file:
"C:\Program Files\TOSHIBA\E-KEY\CeEKey.exe"
if you want to use the function key too, to change power profiles.
The problem is that you have to do this each time you log in as limited user. If it was an Unix O.S. you could set a flag SUID in the files to execute them always as administrator. But this is Windows and I don't know if there is a way to do this!
Anyway, there is another possibility. You can use SpeedSwitchXP tool (http://www.diefer.de/speedswitchxp), instead of the toshiba power management tool. This software is a power management tool that works from a limited user too, but you have to give write access at all users to the following reg keys:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Controls Folder\PowerCfg\GlobalPowerPolicy
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Controls Folder\PowerCfg\PowerPolicies
These keys are necessary in order to modify power schemas. You can give write access to these reg keys with the standard tool 'regedit'.
