Upgrading the DGFF GPUs in the Precision 7530 & 7730

You might have shorted the power delivery. Can you take a look at the power delivery daughterboard (should be near the place where the power cord connects to the motherboard) and see if anything has gone wrong/blackened/etc?

 

Isn't it normal behavior for the light to be off when battery is 100% charged?

Ah, that is normal behaviour. I quoted the wrong bit, my bad. If the notebook is not POSTing, then I was thinking there was a power delivery issue. A problem in seating the DGFF power cable or the DGFF connectors themselves might be an issue. Might consider opening it back up to check.

 

I did once and reinstalled the OEM card (only one DGFF and nothing...

Just to make sure, I can plug the battery on the side and test (I.e. I am reconnecting palm rest keyboard etc without any screw just to test).

It really feels like the power button/connector has an issue but the cable/connector both look fine.

Tonight I'll do another trial and report back.

 

Ran out of thermal paste ✓÷€°€°
That stuff was super thick, like it was past due. Almost impossible to spread.

I bought kryonaut arriving Thursday

Debating if I should still try to get it to post without the paste but no use the laptop if it post.

Edit: Victory!!! It posts

I didn't check into windows or anything. Will wait for the thermal paste.

I'll post an update Thursday

 

Swap done, computer running

It still shows as Intel UHD 63

I will Google search but any pointers on how to get it to "see" the new card? When I scan in device manager it doesn't show up

So I'll first install drivers https://www.nvidia.com/content/Driv...t-international-whql.exe&lang=us&type=Quadro#

Second check the BIOS for dGPU either activate or something: https://www.dell.com/community/Prec...and-set-Nvidia-Quadro-as-primary/td-p/7338385

Will report back

 

Head over to the UEFI settings, and go to General Options —> System Information, and see if you see your new card there. If you do, then you will have to install the NVIDIA drivers.

 

So, I screwed up again, this time big time

I went with F2 at startup to get in some kind of UEFI. Under graphics I checked discrete graphics controler output mode and unchecked enable switchable graphics (likely my error).

Now the screen is black, of course as I now think Ihave set the BIOS to only use the dGPU but drivers are not installed.

I don't see any way to get back to UEFI as I have zero graphics :/ what a moron.

Edit plugging into my TV I am getting an image, will install drivers form there and try tk boot into UEFI

I still can't install drivers:/

And when booting + F2 it doesn't show uefi on the TV but I guess on the screen... I would have to figure out a tab + enter sequence to get to the Load Defaults option button and select it without seeing the actual screen

Did a full CMOS battery disconnect... At least screen is working now.

 

OK, hold up; that's an old version of the drivers.

Download this driver, and install it. You might not have installed the DCH drivers. Furthermore, we need more images: go to Device Manager, Display Adaptors, and screenshot what you see there (On Windows 10 1909, this is Windows + Shift + S).

 

I am not yet back into windows. So many issues not sure why but that BIOS reset didn't go well. Will post as soon as I am back into windows.

That system scan stayed at 1sec left for a while. My computer is very sick

I've never had such screen and recovery before




Even after repair, supportAssist OS recovery crashed...
