My sister has given me her Acer laptop to look at. She said that it was working fine when it randomly shut down. On reboot it worked fine but a few minutes later it shut down. Now it powers on, can hear the HDD fire up and the light comes on but the screen just stays black. It powers itself off after about 5 seconds and then on again and stays powered on but still has a black screen. It doesn't have any sound coming from it, no beeps etc.
What I've tried:
Cleaned out the fan and heat sink with compressed air.
Re-applied thermal paste.
Double checked all cables/ribbons.
Removed 1 stick of RAM.
Removed both sticks of RAM.
Removed HDD.
Removed battery and tried booting with power cable in.
Removed battery and power cable and held power button for 60 seconds.
Removed CMOS battery for 15 minutes and installed again.
Installed RAM and SSD from my laptop.
None of the above have made a difference.
I can't see if works with an external display because it only has VGA and I don't have an adapter.
I have installed her RAM and HDD in my laptop and everything works fine so I guess it's not the HDD or RAM.
Any other ideas?
Thanks.
