Windows 7: Power options/brightness problem!!!!

21 Oct 2013   #1

Windows 7 Professional 64 bit
Power options/brightness problem!!!!


I've this issue from day one! I bought my Toshiba Tecra R840 almost 2 years ago (Win7 Pro, i7, 8GBRAM, 512 GB SSD,...). What about the issue:

My Power Options are:
when running on battery: brightness=40%
when plugged in: brightness=100%

If I click apply, this would be ok for a while (I will say 24 hours). But then for some reason (and I do not change anything) the brightness will go to 40% no matter if I running battery or if I'm plugged! And I will need to adjust brightness again!

Any help?
