P750DM2 dark screen issue with 2080S or 3070 GPU swap


anassa

Recommended Posts

Hey all,

So for my P750DM2 I found a 2080 Super from a x170sm.  I have the dsanke bios, and with the 2080S I can get into the bios, the dsanke splash screen also come up before I press "F2"  to get into the bios. In the bios I can see there is an unknown VGA and the vbios is 90.04.97.00.7D.  I was going to use .inf mod, but as soon as I leave the bios the screen stays dark.  I can tell that it still gets into the desktop as I can restart with start: "windows+x", "u", "u" for shutdown or "r" for restart. I tried to do a blind vbios flash, but that didn't change anything, I tried to start in safe mode but the display still stays dark.  I used DDU to remove the previous driver beforehand too. I don't have an external display btw.

 

Is the 2080S dead? Would it show in the bios if it was dead? Anyone have an idea of what I can try?

Wait a second since when does the 2080 super series works on 775/771 series 🤔 

 

From what I know the only mxm card that does not work on for example 775 are the 2080 super because he is taking to much power that the 775 can't handle for a reason....

 

Otherwise non super 2080,2070 super works op to 3080 without any problems....

I would get an external display (remember TVs work to test this)

Some people use the regular 2080 with 200W mod on the P775 so I think 2080 Super should be fine too. You can always lower the TDP in software to 150W if there seems to be a power issue or something. That's just a guess though.

 

Have you tried launching Windows installation from a USB flash drive OP? Does it stay black again past the BIOS or you can see the screen? I also would recommend testing external ports first too, both HDMI and Display Port if possible.

@zex4 Do you know why that would be the case? As @srs2236 mentioned we already have 200w 2080 cards that work fine. @Meaker I think I am going to borrow a office monitor and bring it home to see if the external works.

 

I just had an idea - would it have anything to do with the internal display? Since the P750DM2 has 30pin, and the P750TM and any of the ones that came with RTX 20 or newer were all 40pin. I assume this can be confirmed with the external display working. I will try the external sometime this week.

The 30 pin cable should still be eDP rather than LVDS so it should still work IIRC.

True that, both 40pin and 30pin are eDP. Well we will see with an external if that makes a difference I guess.

hi. i confirm this with 100%. i have p775tm and install RTX2080 Super, my 330w ac power charger is power off when loading only GPU, and laptop shut down in stress gpu+cpu together. i bought eurocom charger 780w and my power consumption overall in stress tests Aida64 CPU stress+Furmark = 400W power consumption. 

Therefore, we can conclude that the consumption is very high and that the power supply cannot take the laptop in working condition. and I say right away - no power plan settings DO NOT CHANGE the power consumption (battery saving, balance, enterprise, silent etc) of the video card; it does not work with the cool control center v1.0 v2.0 versions and different revisions. Also, the heating is very high, in 5 minutes the temperature in games is -90 degrees and no matter what settings - medium or ultra - the video card still consumes 205-210 watts according to HW info sensors. and when play in games gpu drops frequency to 300 mhz core and 100 mhz memory to 10-15 sec, then power full up, after 2-3 mit - again drop... rtx2080s on p775tm not working properly. and no modded Vbios with reduced TDP down (150w max or 175 w max). only one for x170sm

maybe try flash another bios and EC. i use XMG TM official bios 1.0.28 and ec 1.0.16,  and try official clevo bios 1.0.29  - startup and loading - no issue. Same issue as you -  in bios and windows - Unknown video card.

@kela-slk are you saying it doesn't work at all or the 330w psu won't work? I have the eurocom 780w psu so then it should work right? 

 

Even if it pulled a lot of power you were still able to see the screen right? Or were you not able to see the screen with the 330w PSU?

I will try to flash these and see if I can get the screen working then.

Make sure and backup you DSANKE BIOS - These are getting hard to find if you want to flash back to it after testing.

 

Yes thank you, good idea!

I think it is time to make a folder with multiple different bios/vbios configurations just incase.

Do you have the factory bios on it now or Dsanke!?

Of course power plans won't change anything. The idea is to change the TDP in MSI Afterburner or any other GPU overclocking tool of your choice. Clevo Control Center doesn't support this.

Just tried a 3070 but it does the same thing except now no Dsanke splash screen. It just stays dark, but makes all the sounds of starting up normally and getting to the desktop.  It has to be a display out kind of thing? Or bios? I brought a monitor from the office home, but still need the HDMI cord. Once I have the HDMI cord then I can test to see if an external monitor will work. If not, then it will be re-install the 1080, try the XMG bios and see if we are more lucky.

Good News!! The external monitor helped! I was able to install a modded driver with NVCleanstall. 

Was able to do a Timespy run with:

It looks like it is only the internal laptop monitor that doesn't work.  Still need to figure out why the laptop monitor doesn't work.  I have not updated the bios from the dsanke bios to XMG or anything else. Just added the external monitor.

 

Did a quick little overclock on the 3070:

Sounds too me like one of the following has happened.

 

1) Bad display cable

2) PWM controller for the screen backlight has gone bad

3) Screen has gone bad.

 

It has to realistically be one of those but #1 seems the most likely, Personally I can't wait for my 2080S to arrive and I can shove it into my P870

So just put the gtx1080 back in and screen works fine.  So I will keep the gtx1080 until I get time to diagnose it a little more.

Looks nice!

 

About that internal screen: I would try and use a portable Linux that boots from a USB drive so see if your internal screen can be addressed that way.

 

I had the issue that with a new QHD screen my MSI GT75 would not show a picture any more except in bios but the screen worked with the Nvidia special drivers of several Linux versions that I used to boot the laptop from an external drive. I use Ventoy as I can drop all kinds of Isos on there and boot from it and it was pretty straightforward.

I just tried and Linux Mint 21.3 Mate gets a screen and also allows me to regulate brightness which was another issue that I encountered later with some Nvidia drivers. 

 

After I verified that the screen came on in a normal fashion with Linux it was "only" a matter of finding drivers that work. Your mileage may vary but I ended up with this one:

That is actually a great idea! I will also give that driver above a test run.

I think I will go back to trying the 2080S instead of the 3070 since the 2080S at least gave me the bios while the 3070 wouldn't.

Makes sense as in my case I also had a working bios. Not being able to see the bios is probably something else.

So with 2080S back in I can boot to Linux Mint 21.3 Mate after I mounted the ISO onto the usb using Rufus. It works! So now how do I get into windows and install a display driver? I think I missed the connect there.  Also external monitor doesn't work - unlike the 3070 - but even though I get no display it is obviously still booting into windows desktop. I can even shut it down using shortcuts.

  • anassa changed the title to P750DM2 dark screen issue with 2080S or 3070 GPU swap

Maybe I will need to flash the XMG TM bios or some other TM bios.  But then the question is, is it possible to flash the Bios from the Bios??

My guess is that DM machines might not have a compatible BIOS for 20/30 series cards. I could try and modify a BIOS version for you to try but for that you need a hardware flasher. Or, you could try flashing TM BIOS but I am not sure if they are compatible like that.

I believe the GPU vBIOS can be configured for each output (of the 4 available IIRC) to be configured as a different type of display output - HDMI, DP (eDP), LVDS or Analog. This may be able to be custom configured or copied from another card to work for you, if flashed onto yours to regain the internal eDP output, but I'm not sure this is doable on 3000-series cards (but it was back in the day on 800/900/1k series IIRC) due to baked-in firmware sig checks.
