Power Manager - Battery Stretch options greyed out

When I am running on battery, the various checkboxes for the Battery Stretch options are greyed out. Normally they are only greyed out when running on AC power, but mine are greyed out all of the time. How do I fix this?


I suspect became got corrupted in the registry. I had the problem described at but managed to fix it.


Windows XP SP3, T61 7551-V51, Power Manager 1.73, Power Management Driver


Any ideas would be greatly appreciated, thanks.

Re: Power Manager - Battery Stretch options greyed out


in case you want to use this option properly, make sure, that you have the latest version of Power manager, Poewr management utility, System interface driver and Hotkey installed.

In case once of them is older verison, especially Power management driver, then this situation amy appear.


Let me know you system type and the model .
