    P770DM-G 980M Won't Boot

    If your laptop originally came with a 970M it should also work with a 980M. They are basically the same cards, the 980M just draws more power (and better performance of course). A stronger PSU may be needed (I have 230W) but should still boot and work normally when not under load. The integrated graphics on these machines were disabled, so you need a dedicated gpu installed, otherwise you get no display and the BIOS/EC will just shut the system down after a few moments. There is no way to enable the integrated graphics unfortunately. I think the problem is the card you have is a Dell version, but you may be able to get it working if you do a vbios flash.

    If it's a Dell card it probably has a Dell vbios. You can try flashing a Clevo vbios if you have a programmer, but I have heard that Dell cards can have compatibility issues with Clevo's. When I had this problem I wasn't able to flash because I don't have a programmer. In order to a get everything working I had to get a Clevo gpu because no other cards would work in my machine. I could boot but would just get a black screen and video output.

    Where did you get the 980M card from? And what happens when you try to boot with it?

    Nvidia 1060 Upgrade

    Apparently this isn't a very popular choice of upgrade, lol. Had to pass on the MSI version due to the pcb layout and not being sure if the heatsink would mount properly. Just ordered what looks to be one of the Aetina reference 1060's off eBay, so if anyone is curious I'll update this thread once I receive it on whether it works.

    Nvidia 1060 Upgrade

    I've been thinking about trying to swap one of the newer 1060 Pascal cards (MSI version) into my P770DM-G, which currently has a 980M. There isn't much out there to go by for this particular model (I have come across various threads confirming it's worked for other models), but based on my research the MSI version of the card retains the standard MXM dimensions, so there shouldn't at least be any fitment issues. Can anyone confirm whether this upgrade will work and if there would be any other complications involved?

    Received another replacement card, popped it in, and now everything is back to working.

    P770DM-G 980M Won't Boot

    Not sure because every command I ran through nvflash would return a 'No Nvidia display adapters error' when checking the log file generated using a different computer. Every version. Even when just trying to backup the current VBIOS. Pretty much attempted everything I could considering having to work completely blind, and unfortunately don't have access to a programmer. I've since settled on the card just being defective and have sent it back (ordered from eBay shop in China). Will probably try my luck again this time from a different source.

    P770DM-G 980M Won't Boot

    I suppose that is possible. The original card died due to MOSFET failure. One failed, so I removed it and the card ran on the remaining 2 for awhile (just had to reduce the clocks to avoid black screens when running demanding games), then the remaining ones eventually burned out. I was sure it was something up with the vBIOS since I purchased the replacement from China, but I guess there is no way to know for sure if it's board related until I'm able to test another 980M.

    The motherboard should be ok. I since managed to get the laptop to boot to Windows but there is no video. I've been attempting to blind flash a stock 980M vBIOS using these instructions, , but with no luck. It fails everytime. Since I have no video, I enabled logging through nvflash and the error I get everytime in the log file is 'no nvidia display adapter detected'. I also get 2 beeps after Step 9, but according to the instructions it should only beep once when the flash is successful. It seems that the card and the laptop itself are both working there is just some incompatibility some where.

    P770DM-G 980M Won't Boot

    I recently purchased a replacement 980M (Clevo model) for my P770DM-G after the original died, however, after installing the card the laptop doesn't boot. I only get a black screen, and after a couple minutes the fans spin to max before shutting down, which is the same thing that happens when I try to boot it without any gpu at all. I've tried the reset procedure, unplugging, removing battery, and removing CMOS, to no avail. It does beep before shutting down (I counted 22 times exactly). Anyone have any insight as to what the problem is?
