loud88gt Posted October 13, 2018 Report Share Posted October 13, 2018 Hello, I'm new here and need some help. I've got an HP 8770w that came with the Firepro M4000 originally. I bought a Nvidia K4100M and the corresponding heat sink as a replacement. I've installed it but get a black screen at startup. It almost seems like it tries to start and then the light on my mouse goes out and it tries again. I was going to delete the old drivers and install the new ones after it started up. Should I install drivers first or am I missing something else? My system bios and everything else is up to date as far as I can tell. I can easily do the disassembly/reassembly stuff but my knowledge is limited when it comes to software. Any help you guys can give me is greatly appreciated!

mobilenvidia Posted October 14, 2018 Report Share Posted October 14, 2018 Do the drivers even install ? Does the K4100M come with a HP 8770w as an option ? FInd a HP driver that supports the K4100M and would have come with the 8770w Start here Quote Link to comment Share on other sites More sharing options...
zipper Posted October 14, 2018 Report Share Posted October 14, 2018 8770W was delivered with one of these, so a modified inf is needed: AMD FirePro M4000 with 1GB dedicated GDDR5 video memory NVIDIA Quadro K3000M with 2GB dedicated GDDR5 video memory NVIDIA Quadro K4000M with 4GB dedicated GDDR5 video memory NVIDIA Quadro K5000M with 4GB dedicated GDDR5 video memory K4100M seems to exist on HP Zbook 17 G2 which is a newer model. https://ftp.hp.com/pub/softpaq/sp82001-82500/sp82357.exe has a Nvidia driver for it and should have K4100M included. Perhaps it works.... OK, looked at HP, for Zbook 17 G2 and even 8770W the latest driver 09/25/2017, 22.21.13.8573 seems to support: NVIDIA_DEV.11B7.190A.103C = "NVIDIA Quadro K4100M" NVIDIA_DEV.11B7.197A.103C = "NVIDIA Quadro K4100M" NVIDIA_DEV.11B7.2255.103C = "NVIDIA Quadro K4100M" NVIDIA_DEV.11B7.2256.103C = "NVIDIA Quadro K4100M" Quote Link to comment Share on other sites More sharing options...
loud88gt Posted October 18, 2018 Author Report Share Posted October 18, 2018 I have the latest driver but never get the chance to load it. I used DDU to remove all the old drivers, then install the new GPU and get a black screen. I noticed the numlock light on the keyboard(which is normally on) cycles on and then off every few seconds. The laptop will turn off instantly when I press the power button which leads me to believe Windows is not starting at all. Quote Link to comment Share on other sites More sharing options...
mobilenvidia Posted October 19, 2018 Report Share Posted October 19, 2018 There might be a whitelist for GPU's in the System BIOS, HP are renowned for this Or just an incompatibility Try Ubuntu Live CD and boot from this, if this doesn't work then little hope But if you get the black screen from bootup then there is really very little no driver will fix this Quote Link to comment Share on other sites More sharing options...
S_C Posted July 21, 2019 Report Share Posted July 21, 2019 Hi, Had the same issue with K4100M .
