Hey everyone- i am not very familiar with laptop hardware. I have a Sony VIAO PCG-934A and I wanted to swap harddrives with a PCG-fx140 that i also have. After installing it, i put everythign back together exactly as it was but now my power won't go on at all. When I plug in my AC adapter, the lights (charging, ON, etc LEDs) don't even go on. What did I do wrong? Is there a way that i might have shorted something? i don't smell any burning, i tried putting back the old hard drive but still to no avail. SOMEONE HELP!!!
