screen won't light up
Laptop worked this am, but when I did a shutdown it took about 10 mins. Then tried to boot later and no display would light up.
I tried all the solutions on the web I could find:
Took out battery, tried powering up with just ac cable, no good.
Tried powering up without ac cable, no good.
Tried holding down power button for 30 secs. plugging in only ac cable, no good.
Put battery back in and ac cable in, no good.
Reseated the RAM (and blew out a lot of dust that was on the fan), still no good.
Is it the motherboard? graphics card? Any help appreciated
