the computer wont start. i think the reason is that the power button is broken or out of place because whenever i press the button, it feels different than it usually do. the first time it turned on but then it turned off soon after. then i tried turning it on again but it wont start now. what should i do? is there ne way to fix this or turn on the comp with out the button or is there a way to jump start it? if there is, then how?
