so I have been doing the software update' thing daily and besides downloading 2 or 3 firefoxes 24.1mb each it fixed my intel gfx glitches (new driver?) but my laptop no longer blanks the screen after 10 minutes of no use.

This is critical for me as I just leave my laptop playing music etc so having the screen/system not going into stand by is merde.

any way to fix it?

in system settings everything checks ok in power
