my laptop is toshiba satellite L305-S5955. i leave it open the whole night. then i think it runs out of battery when i plug it and try to turn it on the light signal for battery life, if the cord is plug and when it is on is okay but the screen is really black..
I tried removing the battery and pressing the powers on for like a minute then putting back the batter and the plug but it's still the same...
Please help me.... I need my laptop and really can't afford a new one... this one was Christmas present...
