My Dell's CPU was stuck on 800mhz. Don't know for how long it was in that state as I hadn't done anything strenuous for a couple of days on it. Couldn't find anything useful with google. Finally fixed it. Weird thing was that a reboot first froze and then rebooting again had no effect. Was looking through windows logs when one of them froze and left a ghost text box that didn't go away even if I ended explorer. So I logged out and logged back in and that's when it was finally fixed.
Had previously been messing around with power options and the "turn off battery charging" feature is nice, although not nearly as good as Lenovo's, for preserving battery longevity and so is the "Enable Dell Extended Battery Life". Odd thing was that the brightness for battery mode wasn't being saved every time I went unplugged. Perhaps when I was experimenting with processor levels on battery mode, it got stuck just as the brightness did.
Can anyone shed some light on this? Since it's fixed after logging out and back in, but strangely not on reboot, I don't think it's hardware. Could be BIOS but Dell laptop BIOS had nothing relevant. Does anyone have experience with Dell's "Battery Meter" program and know if its liable to get settings stuck?
Edit: Oddly enough, the brightness is no longer stuck for battery mode using Dell's "Enable Dell Extended battery Life" option. So it would seem very likely that the maximum processor state must have been stuck from when I was testing the usefulness of 0% despite not reverting back to it as the brightness would every time I unplugged the laptop. Question still remains as to whether the issue is with Dell's program or Windows' power options.
Edit 2: I spoke too soon. With the "Enable Dell Extended Battery Life" checked, the brightness issue came back again and this time I noticed that the maximum processor state was also changed to 0%. So for those of you with Dells using the above setting, make sure not to check "Change power plan to power saver".
So with the root of the problem identified to not be CPU related, I suppose this can either be deleted or moved to some other topic such as SFF, Notebooks.
