    Hey all, so I recently put my 980m in my m17xr4 from my m15x and whilst the card will work perfectly, as soon as the gpu load is sustained for a certain period of time the laptop will randomly shut down. It does this whether I use stock vbios or modified ones. My temperature never gets over 71 degrees so I don't think its due to temps and my charger light never goes off (tested both 210 and 240 chargers). Is this due excess power draw or is it something else that I am missing.
    I tested furmark and both times the laptop shut down - both times the gpu never even got to full clocks or got hot.
    When I play games the same thing will happen. clocks will be full and temps will be fine but I will get random shut downs.

    Same problem with mine, m17x r4 with 980m...
    Casually shutdown in games without any reason...

    Today, I’ve cleaned card completely with contact cleaner and put some extra thermal pads between mainboard and bottom vRAM chips, as well as put some extra pads arround heatsink. 3 hours testing - no shutdown :)

    Only one bad thing: bottom thermal pads now heating PCH(that just on top of vcard) up to 100deg, so I put also some pads on it to release some heat to keyboard frame and it temp dropped to 85-90.

    Probably blown mosfet, common problem if you don’t cool them right. 980M has bad habit of destroying them, giving weird behavior like that. 980M core rarely fails

    Most probably yes, as yesterday I put cooling pads on them and so far working ok, will try to remove extra pads from bottom and test again.
