P150HM (6990M) Blackscreen

(Specs in signature) 2 years and 3 months old.
It was working perfectly fine (low temps, Liquid Ultra paste 2 months ago) until I put it to sleep mode.
Hours later, try to resume my work. the display won't turn on.

Forced Shutdown, reboot. Blackscreen. nothing comes up, not even the bios screen.
The Bluetooth light and power light lid up and stays on, HDD light blinked a fraction of a second when boot and that's it...FN+1 works, pressing the power button for 2-3 seconds turns it off.
Apparently it is not booting up at all.

Tried:
Hold power button without power source/battery.
Resit RAM,
Checked connections even disassembled the LCD display cover revealing the back of the display.

all seems fine...I have not even play games on it for months, primarily doing Solidworks.
No unusual signs before this. I suppose my 6990M is dead. haven't got an external monitor to check though. But it's weird it just died without any prior signs of failing, I keep Temps very low, never exceeds 80C when gaming and below 40C idle @20C ambient.

I want to know what my possible options are.
Would it be better off buying new rig after the new release instead of buying a replacement MXM, say 7970M?

Cheers!

 

i had a really hard time finding a suitable reasonably priced clevo 7970m for our 150hm chassis (dells are cheaper but dont work). just refloat the solder joints in a convectional oven 180c for 10mins and she should come back to life. solidworks is pretty gpu intensive afaik

 

If it's the board or GPU, you can attempt a reflow before you look into replacements. If it's another component - such as the CPU, you'll need to swap it out. This sounds mainboard related.
