Power plan settings aren't persistent
I have my power plan set to Energy Star with display brightness set around 40% when on battery and 100% when plugged in. It seems to get reset periodically to the default which 40% for both battery and plugged in. I haven't been able to reliably reproduce the problem but every few days the plugged in setting gets reset to 40%. Is this a known problem with Windows 7?
