About a month ago, my laptop started making 8 beeps when I tried to turn it on from hibernation mode. No display on connecting external display nor any colours on D+power on LCD. I gave it at a repair centre and they replaced the motherboard and it was working fine for about a month and again the problem has crept in out of nowhere. It was working fine and I put it in hibernate and when I tried to bring it back, it wont display and play 8 beeps. Again no display on connecting external display nor does it give any colours when I power it ON holding down D.
What seems to be the problem here?
I am out of warranty.
