[Solved] Lenovo Legion 5P won't use my dedicated GPU, instead prefers the IGPU.

[Lucky26]

My specs are as follows:

CPU: AMD Ryzen 7 4800H with Radeon Graphics

RAM: 8GB

GPU: NVIDIA GeForce RTX 2060

OS: Windows 10

 

In the past, I have been able to play games in both VR and on the flat screen with great fps and quality. Now, I am unable to play any game (although Minecraft runs on the IGPU) at more than 2fps because the laptop will only use the integrated GPU. No, I didn't mess around with settings or download any malware. Sometimes when I am playing a game, I can see that the NVIDIA card is being used, but so is the integrated. When I open CCleaner, it sees the IGPU and not the dedicated GPU. Also, the Oculus Client tells me that my specs are below minimum, once again because it only sees the integrated GPU.

 

I have tried everything, from selecting the 'High-Performance NVIDIA processor' in NVIDIA Control Panel, to right clicking and selecting 'Run with graphics processor' > ''High-Performance NVIDIA processor (default)', to selecting specific apps and games and making them run on the dedicated GPU in Windows Settings. I have even tried to disable the integrated GPU in Device Manager, but then Minecraft and also the Oculus Client were unable to run. Any help would be much appreciated.

Hi and welcome to ExTS

 

If you have selected ''High-Performance NVIDIA processor (default)', and the system is still defaulting to the onboard graphics then it could be a problem with the graphics card itself.

 

Do you have another that you can try?

 

I assume that you have tried uninstalling and re-installing the NVidia drivers ?

No, unfortunately I don't have another GPU. Sometimes the dedicated GPU does show usage in task manager but it is usually below 30%. This also only happens when the IGPU is at a high usage %.

Try re-installing the drivers.

 

You could try re-seating the Graphics Card.

 

If you have a volt-meter you could check the voltages on the suplimentary power supply [ 8 pin I think ]

If the cables to the connector are yellow and black the yellow cables should be 12v [ black are ground ]

I am not too sure if I will be able to re-seat the GPU as this is a laptop, is it possible to do that on a laptop?

[KenB]

Sorry - assumed it was a desktop.

 

You are very limited now as to what you can do.

If re-installing the drivers doesn't solve it I am not sure where you can go with this.

[Lucky26]

Yes, I have re-installed the drivers and that didn't seem to work. Thanks for the help anyways!

[Lucky26]

Finally! I fixed it by switching to 'Discrete Graphics' in the BIOS!

Thanks for the feedback.

 

Good to hear that you solved it :)
