Hello, you are not alone. Same issue with me.

#

I found the issue

#

The issues is you updated your Intel driver 32.xxx and windows update automatically install Intel display driver 31.xxx this corrupts Nvidia driver and your device manager will show you, genetic display driver

#

anyone find a solution to this? i am having the same issue. detects when connected to an external monitor but without it, i get the same error

#

Nope. Sadly no fix at all so far

#

Surely this is started happening with windows 11 + nvidia + Intel drivers. So one of them is conflicting with another which one is unclear at this point

#

We might need a Bios update, last update received for Legion 7 pro gen 8 is November 5.

#

This is what happend when I am in hybrid mode.

#

Does it have anything with Legion took kit?

patent summit Mar 31, 2026, 3:18 AM

#

I'm having issues where if legion toolkit is running, it will disconnect my dGPU and it won't come back until I do a hard ec reset

#

ive had this issue on a previous laptop before as well with legion toolkit

analog jacinth Mar 31, 2026, 3:19 AM

#

Nope, I twice clean install windows and all software update through Lenovo support. Once all the software updated to latest version once the system restarts hybrid mode bricks.

#

I do installed Lenovo vintage software

patent summit Mar 31, 2026, 3:21 AM

#

hm

#

might just be an issue with hybrid mode on this laptop then

patent summit Mar 31, 2026, 3:22 AM

#

analog jacinth This is what happend when I am in hybrid mode.

hm.
yours is showing a Microsoft basic display adapter, which wouldn't be showing if the DGPU is gone

#

would you mind going to the bios and showing what it says here?

analog jacinth Mar 31, 2026, 3:23 AM

#

Mine shows 4090 in the Bios.

patent summit Mar 31, 2026, 3:24 AM

#

I don't think it's a BIOS issue then

#

dunno what it is though

#

I could be wrong

analog jacinth Mar 31, 2026, 3:24 AM

#

Now am currently using DGPU mode. It works fine but hybrid mode broken

#

Something is bricking entire thing. Could be windows, could be nvidia software it self. Either way this all started recently with windows and latest Intel 32.xx driver

Which version of LLT are you using?

patent summit Mar 31, 2026, 5:00 PM

#

I found out that it was a dead SSD that lenovo support asked me to putback in to confirm was dead that was causing the issue

SSD and VGA driver? How is it related to this issue?

patent summit Mar 31, 2026, 10:13 PM

#

I suspect it was causing issues on the pcie bus that caused the GPU to drop out and not reconnect

analog jacinth Mar 31, 2026, 10:16 PM

#

Mine is just fixed randomly. I used Lenovo Legion toolkit and tried auto hybrid mode rather than hybrid. . Now system works perfectly fine both GPU.. I will skip any updates now on.

Oh, really?

#

So no issues with LLT

patent summit Apr 1, 2026, 2:51 PM

#

yeah I must have been misremembering what happened last time

#

I swear this happened before and that I had narrowed it down to LLT, but my memory has been proven multiple times lately to be very unreliable

analog jacinth Apr 3, 2026, 7:20 AM

#

Each time when I restarts the pc this is what happens
