hi guys! i recently purchased a samsung series 5 notebook (NP510R5E-A01UB) and it has a weird brightness problem.. its on windows 8.. whenever i open my laptop when its charging it open with full brightness.. but if i open it n its not charging then it opens up at half brightness and m not able to change it by any way.. i tried function f3,f4, settings , power saver plan, but nothing seems to be able to change the brightness.. but if its plugged it opens at full brightness :/... but i am not able to change the brightness even when its charging in or not... any suggestions?? i am stuck at full or half brightness...
