Can you force a laptop to use integrated GPU?

post #1 of 14
Thread Starter 
So my Lenovo Y50's GPU died. And it's soldered onto the motherboard. No warranty so no need to suggest that. Anyway, can I somehow force the laptop to use the integrated GPU of the i7-4710HQ?

Specs if you're curious:
i7-4710HQ (quad core, ah and it has Intel HD Graphics 4600),
GTX-860M 4GB,
16GB RAM,
512GB SSD,
UHD display.

You should be able to go to the nvidia control panel and set it up to only use the integrated gpu.

Ah I didn't mention a crucial info. The screen remains turned off. It simply won't turn on (took the laptop to a shop and after testing they said the GPU is faulty). So I can't get into Windows. Any other ideas?

Try connecting the laptop to a secondary display to see if you get anything.

Maybe removing the GPU chip from the mobo, will get the computer to automatically kick in the iGPU?

I did try connecting it to another display before, no luck. Removing the GPU is not possible, it's soldered onto the motherboard.

I'm gonna be honest with you. I don't see any possible way for a dead Nvidia GPU on Optimus to be messing with your screen.
The HD4600 handles everything from the moment you press the power on button, and I doubt really hard that it is dead. The nvidia GPU is connected to the Intel GPU, regardless of it's state the computer should boot up atleast.
All you have to do is disable the Nvidia in the device manager and it would use everything on the Intel.

Are you sure you don't have a broken wire for the lcd screen, short circuit etc?
Are you sure that specific shop you spoke with have electronic capability to evaluate your computer?

I'm not into electronics, but from my work, studies and experience the Intel GPU always turns on. Thats how Optimus works, the GPU image comes always from the HD4600, which is rerouting the Nvidia.

Trusted Reviews:How Optimus Works

Not saying they aren't correct, but there is more to it than just the Nvidia card not working.

Is it now? Well it won't be for long (that is if you have nothing to lose)!

@Tokkan: I was thinking that too before, that it might be some problem with the screen (maybe the wire as you've said). And I don't think it's short circuiting cause the small lights on the laptop work, and so does the keyboard back lighting. Just the screen remains off when I turn on the laptop. Also, I can't disable the nvidia GPU through Windows since the screen won't turn on. The shop seems to have a good reputation/rating so I'm not sure. They specified the problem as "Graphics Memory failure".

@Gunderman456: I can take a look at the GPU once I take my laptop back, but I don't really have any soldering/de-soldering skills, we'll see I guess.

Did you try all the video outputs? Generally at least one of them is going to be powered by the Intel HD graphics instead of the GPU.
