Installing 675m and its driver on Clevo P150HM/Sager 8150M

I just got my 675M today and after I put *MY PREEEEECIOUS* into my laptop, I was very happy and couldn't wait to use it. I turned it on, and the bootup is smooth, HOWEVER, after I got in, the device manager cannot recognize my 675m, instead it lists 675m as "Standard VGA Graphics Card". I thought it might be that my intel HD 3000 took over. Then I tried to install the driver nevertheless, and the driver said it couldn't recognize my 675m either. I wondered ...

*Long story short*

Then before I realize it, it's already been 6 hours for me, and I have successfully make *MY PREEEECIOUS* work. It turns out I just need to mod my .inf file to install the driver. Thanks to LapTopNut for his discovery! and I will talk about how exactly he modded the file.

Now a couple of things I have learned:

1. Go to your device manager and check the property of that "standard VGA graphics card", or any thing else that says VGA controller.

Under Details tab, check the property of Hardware IDs. Then identify if it's actually the card you installed with this site PCI Vendor and Device Lists

If it is your card, then you just have to mod your driver's .inf to install your drivers.



2. Using the info found in 1, we can then start modding our .inf file, you can find these .inf files under the Display.Driver subdirectory: nvcv.inf, and nvdm.inf. Open both files with text editor (gedit, notepad++, you call it), use the find function to find your card's name and it will look something like this :

NVIDIA_DEV.1212.0270.1558 = "NVIDIA GeForce GTX 675M"
NVIDIA_DEV.1212.0271.1558 = "NVIDIA GeForce GTX 675M "
NVIDIA_DEV.1212.5105.1558 = "NVIDIA GeForce GTX 675M "
NVIDIA_DEV.1212.5102.1558 = "NVIDIA GeForce GTX 675M "

Note:
1212 -> DEV_
0270.1558 without the dot -> SUBSYS_

Change one of the numbers on the left with the your card's properties. After that, search again with the number you modified (XXXX.XXXX.XXXX), and you should be able to find 3 occurrences of those numbers, and change them all to your card's properties. Those 3 occurrences should look sth like the following:

%NVIDIA_DEV.1212.0270.1558% = Section024, PCI\VEN_10DE&DEV_1212&SUBSYS_02701558
%NVIDIA_DEV.1212.0271.1558% = Section027, PCI\VEN_10DE&DEV_1212&SUBSYS_02711558
%NVIDIA_DEV.1212.5105.1558% = Section059, PCI\VEN_10DE&DEV_1212&SUBSYS_51051558
%NVIDIA_DEV.1212.5102.1558% = Section059, PCI\VEN_10DE&DEV_1212&SUBSYS_51021558

After modifying both files, launch the setup.exe file and you should be good to go.


3. Some side notes:

• Make sure that your bios / ec is up to date.
• If the above method didn't work for you under normal system, try it under safe mode with admin right

At the end, thank you guys for providing info on the forum in the first place.

 

very nice step by step info, thx for sharing! +rep

Haha thanks jaybee

 

Wich bios version do have you on your 675M ?

 

Oile, I don't remember modding any vbios. So it should be the default one.

 

Hey, installed a 675m using the guide given by this thread, thanks a bunch! Could anyone tell me where to get the latest BIOS for the P150HM with 675m? thanks

 

here u go:


https://www.box.com/shared/mgqk1z956bxtlb8yeoe3

beware tho, the package includes both the latest bios and ec for the p150hm and the p170hm. so be sure to pick the right one

hey thanks for the info,

I just got the 675m installed, downloaded the latest driver (314.22) from Nvidia's site, I tried looking for the two files, nvcv.inf and nvdm.inf, ( i found nvcvn.inf and nvdmn.inf, as well as a whole bunch more .inf files) once I opened those two up my brain pretty much exploded and I don't really know what to change...lol, sry I'm totally worthless on this one. any help???

 

if its too much for u, u could always try laptopvideo2go.com for already modded nvidia drivers

hey thanks,
I ended up bringing it to a friends shop, they modded it with these instructions, thanks again OP, got the 675m running in my p150hm now!

 

I wrote a more detailed version of this article here: http://forum.notebookreview.com/sager-clevo/746245-installing-nvidia-drivers-modding-inf-files.html

 

Just got this card pulled from an P170EM. I can not install the drivers. It tells me that no compatible hardware was found. I tried modifying the drivers myself and try the laptopvideo2go.com drivers.
I think its a bios problem cause I can not find the card in the device manager under the tab "display adapters". I only see the "Standard VGA Graphics Adapter"
However this "standard VGA Gr. Adapter" card got the same HW Id as the other guide on how to install the card.
My HW id-s is :
PCI\VEN_10DE&DEV_1212&SUBSYS_51021558&REV_A1
PCI\VEN_10DE&DEV_1212&SUBSYS_51021558 -Should I choose this one??
PCI\VEN_10DE&DEV_1212&CC_030000
PCI\VEN_10DE&DEV_1212&CC_0300



BTW I updated the BIOS (with the bios from the link here) with success but for no help. However I managed to update the BIOS before the EC. Could that be a problem?

 

Follow the guide I linked to above for step by step help. Yes, that is the one you should choose, but only the end part of it -- Again, my guide may help you a little more. Also, I don't recommend using drivers found on the internet or messing with your BIOS (this should be your last option.)

 

I would like to contribute some of my findings, as just moments ago I finally solved the lack of brightness controls on Windows 7 with my P150HM and GTX 675m! If you are in a hurry, download the pre-modified .inf file attached and drop it into the Display.Driver folder to replace the old file. No guarantees it will work though, so read on to see how I did it.

While the original post will get your video card recognized and also helped me out a lot, it is now a bit out of date. I get the feeling that nVIDIA changes the layout of their .inf files frequently, so I can only say that this works with 344.11 drivers, but you only need to change the nvcvi.inf file.

The modified .inf file that laptopvideo2go also failed to bring back brightness controls, so unfortunately the only way to get them back is by doing things manually!

Additionally, the original post's suggestion to change any one of the matching lines to your hardware is not entirely correct. What you have to do is look for the 580m variant (It will be very similar, CTRL+F for 5102.1558), check which Section0XX it corresponds to, then find the 675M line that also matches that Section0XX, and rename that line (and the 3+ other times that line appears in the file). Once you do that, do a clean installation (it should be a checkbox at some point during the installation), restart your computer, and brightness control is back!

I think if I have some time, I will make a new 2014 how-to thread with better instructions, because I know for a fact I am not the only P150HM owner who swapped a dead 6990m for a 675m, booted up their system, and had their retinas fried.
