    The WWAN slot does not support mSATA drives. It will support mPCIe cards other than WWAN. mSATA drives are not mPCIe cards, even though they share the same form factor.

    Same happend for me on M6700 - GPU is identified as unknown with 3.5GB of VRAM inside BIOS, works out-of-box on Windows with generic drivers.

    For those of you that upgraded to a 980m GPU, how is it under battery? Is it usable when when throttled for power reasons? I'm not planning on using it a lot on battery, but it'd be nice to be able to play a game for 10-15 min here and there. I currently have a K3100m, and can play some games decently when plugged in, but when it's throttled to 165Mhz on battery, it's basically useless.

    I'm wondering if the higher TGP of the 980m will make it throttle down to the same performance as the K3100M anyway.

    I have a M5000M in my M6700 which has the same specs as the 980M. While on battery it is basically stuck at the idle performance state. Games work with a substantial cut to the framerate (would have to go and lower graphics settings to get things up again — not really worth the hassle). I always realize immediately when I move the laptop and forget to plug the power in...

    These systems can only draw 100W from the battery so there is no way you're going to be able to run the GPU close to its maximum speed (which takes 100W all by itself).

    Thanks, I'm going to give it a shot anyway.

    It looks like a mixed bag recently on whether drivers need to be modded in order to install. Did recent driver updates include the right device ids?

    I'm also curious if people are running UEFI or BIOS and if that makes any difference. My M6800 is a Win10, but was upgraded from 8.1 and is set to legacy BIOS.

    Highly likely that you will have to modify the INF. Which means you will have to disable driver signing or sign the driver yourself. (I have directions for signing a modified driver in my M5000M upgrade thread, linked in signature.)

    I recommend UEFI with secure boot turned on. You can switch a legacy installation to a UEFI installation with the mbr2gpt command. https://www.windowscentral.com/how-convert-mbr-disk-gpt-move-bios-uefi-windows-10

    Well, one step forward, two steps back.

    The good news was that I installed a 980m and was able to boot into Win10 just fine and install drivers with no mods. Awesome! Ran a quick benchmark on battery; performance was on par with AC powered K3100m.

    The bad news is that when I was taking the palm rest off, I noticed the socket for the power button board was bent over. The bracket holding the socket to the motherboard was broke loose and it was just being held in place by the solder joints. I bought the laptop used, so the prior owner must have given it a good yank when they disassembled it and broke it loose. I carefully tried to bend it back in place, intending to epoxy or hot glue it down for support, but the solder joints snapped off.

    I managed to repair the solder joint, but a few of the pins on the socket had broken off short, so it was very difficult to get a good connection. I must have bad connections on a few of the pins yet, because the power button works, but the rest of the LED's don't work and the touchpad doesn't appear to be getting power. Or maybe I shorted something out and zapped the motherboard. =(

    Anyway, I have a replacement motherboard on order now. (GDMGC) .

    Got the motherboard replaced and everything is working well. I wondered if the different BIOS would matter at all (replacement is at A11, my original MB was at A19), but didn't seem to affect windows at all. I re-installed drivers just to double check, but didn't have do any driver modding. This thing is all set.

    Yes, I did it and please note that the top cover (to hold screen) has to be replaced also (thicker).
