Ok ive found out,there are two ways 2 do it 1u just need to take out the battery, and Press the on/off button for 5seconds, the 2nd is more drastic u need to dissasemble all parts and take off the small battery(its even in PCs) and hold iit for ten minutes, then its going to be ok (ive did the second way, because the first way works only on some notebooks)
