I have a samsung N150 plus windows 7 laptop... been over 3 months since i got this new one! and i haven't been able to reduce the brightness of the screen a BIT!! at all..! which inturn is eating up my battery! this started happening couple of weeks back.. i tried everything like restarting and going to control pannel etc! NOTHING works man! feels irritating to have your battery reduced sooo drastically! I would be grateful if ANYBODY could help me out with this! thnx!
