After shutting down my laptop, the next day it would not boot. All it would do is the cooling fan would come on and stay on and the two led lights indicating battery and power would also be on. And the hard drive would get recognized for a split second but then nothing would happen. I would leave it powered on but nothing would happen. I tried using only the battery, then just the power cord but still nothing. Then it stopped even powering on, the only thing that happens now is the led light for the battery charger is on and the D drive gets recognized for a split second. I did a little research and found out that is was most likely the motherboard and replaced it but it still only recognizes the D drive and doesn't power anything up. I have also tried booting w/o the ram and nothing has happend. Any help would be appreciated. Thanks.
