Yoga 730-15IKB Nvidia GPU Not In Device Manager/No Switchable Graphics Option In BIOS

2020-11-16, 3:53 AM

I recently discovered that the GTX-1050 is not being detected by windows, and there is no option in the bios for swappable graphics. Device manager only has the Intel UHD-620 listed under display adapters. There are no "Unknown Device" listed anywhere else.  I have tried updating the bios, rolling back the bios, updating windows, rolling back to a recovery point, update intel drivers, rolling back intel drivers. Nvidia drivers will not install. I have tried the signed Lenovo drivers for Intel and Nvidia, and the drivers directly from Intel/Nvidia. 

 

I have considered that maybe this model can be shipped without the GTX-1050, but I have verified the SN through Lenovo's support site, and it even has the Nvidia Geforce GTX sticker on it.

You're very welcome! Even though I can't find the model number on our PSREF page any more (product was withdrawn already), I was able to find the exact configuration of your model through our internal network and had to find out, that the model 81CU0009US isn't coming per-configured with an nVidia GPU :/

 

I don't understand how your machine can be labeled with the nVidia sticker if there is no dedicated GPU in it, but if the seller of your laptop advertised it as a model which does have the nVidia GPU, I would advise getting back to him and confronting him with the false advertising.

Hello Lleshlo,

 

just to double-check, could you post the model number of your machine? You can find it (MTM) in Lenovo Vantage on its bottom black bar next to the serial number of your device.

 

Based on the description it sounds that the dedicated GPU in your machine is defective and would need to get examined by our service.

 

Best regards,

*Thank you for the quick reply!

 

 

The MTM on the underside of the laptop is 81CU0009US.Additionally the same number is listed as "Product number" in Lenovo Vantage.
