Yoga C940 High CPU when using integrated webcam

2021-01-13, 20:47 PM

Hi, I'm experiencing this behavior for a while now...

Whenever I turn on my webcam, CPU consumption skyrockets in the computer and renders most (if not all) applications useless. I have to either manage to deactivate the webcam or kill the program that is using it to go back to normal.

 

I've tried:

- Updating Drivers: no effect.

- Using alternate drivers: no effect

- Uninstalling webcam drivers: no effect.

 

Any suggestion? It's becoming very frustrating not to be able to maintain a simple video conference and be able to multitask with other application at the same time...

 

Thx

Alex.

Welcome to the Community Forums @Alex_w2004 !

 

Nice to have you here!

 

Just to ask:

 

- Can you please provide us your device's MTM (machine type-model) number for us to check your device's specifications?

- Can you also tell us the exact drivers that you have updated as well?

 

We'll be waiting for your response.

 

Thanks,
