Thinkpad W541 Nvidia card not visible/working

The NVIDIA Quattro of my Lenovo Thinkpad W541 doesn't seem to work anymore.

 

I noticed this problem after I tried to instal the latest nvidia drivers. I couldn't, and then I realised that the nvdia card has not visible at all. On the Device Manager, under the display adaptors tab, you could only see the onboard Intel graphics. The NVIDIA was visible only when the hidden devices option was on. Unfortunately, thinking that it might help, I right clicked on in and clicked uninstal. Ever since, I never saw the NVIDIA card again.

 

Around that time I had updated the BIOS of the computer, if that plays any role. I currently have the latest update, but still no sign of the on board card.

I tried to see if the card had any visible damage, but I couldn't get the **bleep** cooler fan system to unscrew! 

 

Any suggestions would be extremely valuable! Thank you.

Use DDU to clean out the rubbish.

And how could that help? I don't even see the card on the device manager.. Even if I try to install the drivers, I will get an error that there is no nvidia card on my computer.

Just for checking, you have your W541 attached to a docking station and external monitor, right?

Yes ,indeed I usually have it on the docking station with the external monitor. 

 

The problem persists even when the laptop is not docked .

You can't install the Nvidia drivers with an undocked Laptop, I had to experience this myself when I rebuilt a W541 of my own.

 

The Optimus drivers will only work when docked AND the video mode in BIOS is on Advanced...  (so far I remember)

 

There is a thread about this here in the forum. I'll try to find them and post it here, check this same post later for further edits

 

Edit: Thread found click me!

Thank you for your reply.

The suggested thread is not applicale for me. I cannot see/detect my graphics card at all! It is  not possible to install anything.

Re: Thinkpad W541 Nvidia card not visible/working

I don't see the NVIDIA card neither in the Device Manager (even hidden), nor in the BIOS . I run a  LENOVO system diagnostic, and the diagnostic did a test ONLY for the Intel graphics, which I find very strange.

I have the latest BIOS version GNET88WW 2.36.

Which drivers did you try to install? This one here? click me!

 

Unfortunately I have no docking station for my W541 so I can't try to update the drivers myself. Keep in mind the above software has to be installed with your laptop docked and attached to an external monitor.
