Hello,
I have a problem turning on my dell n5010 laptop with win7/ubuntu dual boot , I was doing some blogging using ubuntu and I went to have lunch and left it on but when I got back I found my laptop dead with the black screen and not turning on again with only the power led always on then the hdd led for a few seconds but not hearing any beeps and not seeing anything on the screen.
I have followed some solutions posted before but none of them worked.
1 - I tried to remove battery , ac and press power button to drain static electricity then trying to boot with ac adapter only but it didn't work.
2 - I tried the LCD test and tried an external monitor but neither works.
3 - I tried removing the memory modules , cleaning and reinserting but no change.
3 - I tried Dell Diagnositic but the only difference was that I heard 7 repetitive beeps when on the mode but not seeing anything on the screen .
Any help would be appreciated. thanks
