A month or so ago my laptop shut off and smoke came from my vent. It wouldnt turn back on so i asked around and I heard my motherboard was fried. Well today I was bored and opened it up. I was looking for any kind of burn anywhere. I couldnt find anything. I tried to track the smell back from the vents to find the smell but the smell only is at the vent. Well, I decided to try and plug it up and when I did i seen a little flash in the back of the computer. I wiggled the power cord around and seen some lights and some popping and then I suddenly smelled that burnt smell again. Well I got bored and put it all back together and when i finished i noticed a blue light on my computer (a light of hope!!!) and when i pressed the power button it booted back up! the computer booted up as if nothing happend. SO, I am now asking what should i do to fix my computer. Buy a new power supply? If so, how do i find out which kind it is? Thanx for your help in advance and sorry for the story lol
