    I apologize for the lack of details in this post, typing this from a cellphone. Last night I shut off my M17x R4 as normal when everything was working fine. This morning, I can not get the laptop to power on at all. No fans or lights come on, it's as if the power button isn't doing anything. I've tried pulling the battery and CMOS battery and then holding the power button for thirty seconds but that did not change anything.

    Thanks,
    Eddie

    Weird. Last time i had that happen was after a bad BIOS flash, but I don't think you did that. All I can think of is pulll the battery, CMOS, and 7970M and let it sit overnight, and then hook everything back in and see what happens.

    I flashed the BIOS two or three weeks ago but it was working fine after that.

    Is there any kind of sensor to ensure that the bottom cover is properly in place?

    No, there is no sensor for it. But if you've been in there recently...you may have shorted something if all your cables/screws weren't properly in locked down. Only other explanation for this would be a blown capacitor somewhere on the motherboard.

    I last had it open a few days ago to replace the 7970m but it has been closed and working since then. I've visually inspected all of the motherboard that I could (removed the keyboard and bottom cover) and I don't see any swelling or burst capacitors.

    You could try to blind flash the BIOS.

    The cause of the issue was the 7970m, this is what its board looks like:

    I found this when I noticed that there were fairly large singe marks on the heatsink.

    How bad of an idea is putting an 980m in this? Would my low-end CPU be too much of a bottleneck?
