i am using a hp miini 210notebook..1week ago I was using it when my battery level was 8 % while charger plugged in..suddenly it turned off and wontt turn back on while plugged in charger...infact it doesn't show any led indicator while charging...I tried to force open it while disconnecting the battery...but it didnt work too.. shall I press the power button for 60 sec? as I have seen many ppl are saying it worked for their laptop?
