Ive just aquired a Toshiba Sat Pro M30 which has a function button to adjust the screen brightness and everytime I switch from mains to battery vice versa it automaticly switches the brightness to the lowest setting. This is obviously some kind of powersave setting but it seems a bit stupid that if Im using it on full brightness with the battery then plug it into the mains it jumps back down to lowest brightness, whats that about? It doesnt sound too bad but does get quite annoying after a while. I dont have the factory install disks and Im not 100% sure all the drivers are installed, could this be a driver issue? Ive had a look on the Tosh site and found loads of various drivers but nothing that would have thought related to the screen brightness. Can anyone point me in the right direction or even let me know if this is how Toshiba laptops are supposed to work. Cheers. Pete.
