I'm having the same issue. I have a P150SM and a 970M 6GB. I updated to Windows 10 and nothing seems to use my GPU. The light on the laptop showing if the GPU is powered turns on occasionally but never stays on for more than a couple of seconds. I've tried with the stock BIOS 1.03.05 and Prema Mod BIOS v2 and Prema's 970M vBIOS. I've also tried uninstalling the Intel and Nvidia drivers with DDU and installing them fresh from the websites rather than through Windows Update.

After updating to W10 you need to use a driver with modified .inf-file (LaptopVideo2Go: Drivers). But before you can install it you have to disable the driver signature enforcement (how do I disable driver signature enforcement win W10 preview? - Microsoft Community).

That does the trick for me.

Hey prema,

are you still working on a new bios-mod for the P170SM (with native 9x0M support)? If so, is there an ETA or is there anything I could help you with (e.g. a lil donation )?

cheers

I will definitely enjoy this card . The temperature of the gpu decreased by almost 40°C compared to my "old" 8970M (58 °C now, was 98°C).

after several more hours i finally made it at 03.00 am . my .inf.-mod was alright - my problem was a totally different one: i had to allow the installation of unsigned drivers (not sure if this is the suitable english translation ) in win 8.1. i was only using win7 before that, so i didnt know that i had to deactivate that.

it works perfectly well now!

hey,

today ive received my gtx 970m for my p170sm. im using your latest premamod. unfortunately, i cant install a driver, even after modding the .inf-file. maybe i did it in the wrong way. im using win 8.1 x64 and i tried to use the latest nv-driver.

i only added lines 11601 and 1152 (; NVIDIA Windows (64 bit) Display INF file ; Copyright © NVIDIA Corporation. - Pastebin.com). but im not quite sure, if that is enough or wrong.

maybe someone can help me or provide a proper mod.

thx
