Windows 7: Power plan - do not keep settings!

Power plan - do not keep settings!


I'm running Win7Pro 64bit in a Tecra R840 laptop. My power planning regarding LCD brightness is 40% if running on batery and 100% if plugged in.

The problem is that, for some reason, I can't keep these settings and Windows (?) change it to 40% on batery and plugged in. Example: I change settings to 100% if plugged in (and my laptop is plugged in). The brightnes is at 100%. Then I shut down and start with batery. Brightness is 40%. Everything ok until now...but if I plugged in again the brightness will stay at 40% and if I go to power options I can see that the plugged in option changed to 40%!!!!

Any help will be appreciated.

Do you click Save Settings after changing them?

If you run HD Tune it will mess with power settings.

Windows 7 Ultimate Retail Box (64-bit installed) + Service Pack 1

If you do the save power settings and reboot with it on outlet power the whole time, is it at 100%?

Just wondering if you are going to outlet power while it is still on, via battery, and at 40% setting, and that is causing it to lock 40% for both somehow.

Is that laptop running any brand specific software at bootup?

Run msconfig.exe from search box and go to the Startup tab for the list of items.

Yes and no! If I reboot with the outlet power the brightness will remain at 100% sometimes...! Sometimes it will be at 40% brightness.
Yes it runs flashcards from toshiba.
