ive just replaced a cracked screen and when i turn the power on the blue light comes on and the fans start for 3-4 secs then turns off. the blue light stays on mind and the screen does not light up, ive changd back to the old screen and now this also will not light up can anyone help me please.
I think your laptop is done for. You might have broken/fried something when you opened it up. You can try hooking up an external screen... But the fact that the Fan stops and the computer stays on... that's not a good sign.
