Need information from lost Dell support page

[K4sum1]

With my M4800, my internal display often turns off, and I can't turn it back on without rebooting. I have no idea why it does this. There appears to have been a Dell support article about the issue, but it doesn't seem to be available or archived anywhere? Does anyone have the page archived or know of an archive that has it?

Do you have graphics switching turned off in the BIOS?  Does it do the same thing if you turn it on?

 

When I did Quadro M5000M + Precision M6700, it would have reliability issues along these lines unless I just kept Optimus on all of the time.  (The same issue did not occur with Kepler GPUs.)

Isn't your M4800 running an unsupported GPU iirc? Could be something to do with that. Also is it only happening OS side or does it happen in the bios etc too? What also triggers it?

I want to say it's fine with it disabled, however I'm currently running with the iGPU for working brightness on the internal display.

lucky you. i started using it with optimus off for a couple of days and when i wanted clean install it would show a dark screen.  i reset bios settings same di not change a thing. it got fixed after i removed the DGPU.

I did some more testing, sometimes the display wouldn't turn on with boot. After disabling the iGPU, there's no issues.
