Yoga 2 Pro Webcam and Screen issues

I am having two issues with my Yoga 2 Pro:

 

1. The Webcam works intermittently. The device appears and disappears from the Device Manager listing. This problem has deteriorated to the point that the camera mostly doesn't work.

2. The Screen goes black / flashes, then works correctly again. This happens much less than the camera issue, but I'm expecting it to become worse based on what has happened with the camera.

 

I believe these issues are related - likely a loose connection or faulty cable. My machine is out of warranty. Is this a known issue that Lenovo will repair for free?

Re: Yoga 2 Pro Webcam and Screen issues

Hi Pwillies,

 

Welcome to Lenovo Forums.

 

No, this not a known issue for any model.  To fix the flickering problem, you should first check the laptop cables for loose connections. You try updating BIOS.

 

If still issue persist, also there could be a chance where internal cables having loose connections. Hence I would suggest you to visit the nearest Lenovo service center for better assistance

 

Hope this helps.  Please let me know your findings.

 

Regards,

Shashi

Thank you for the reply. I will open up the machine and try to reseat the cables to see if there is any improvement. My WebCam is basically no longer functioning. I already updated the BIOS last year when I upgraded to Windows 10.

Re: Yoga 2 Pro Webcam and Screen issues

+1 on this lenovo. Yoga 2 (about 2 years old) witht the exact same issue. Has slowly gotten worse to the point it is no longer usable. Interestingly enough it seems to be recognized (intermittently) "unknown us device (device descriptor request failed).

 

When i uinstall this mysterious usb device, VOLIA! Easy cam pops up under imaging device! Unfortunately it is very short lived as easy cam disappears within 30 seconds and "unknown usb device" returns.

 

My guess is poor hardware, but i certainly hope that Lenovo comes with software fix.

FYI- multiple restore to factory settings have not corrected the webcam issue

Re: Yoga 2 Pro Webcam and Screen issues

I have isolated this issue to an unknown USB device (im 99% sure this is the malfuctioning webcam)

When this mystery usb device is uninstalled the Easycam device is recognized under imaging devices, however it is gone as soon as it arrives as the usb device listed above returns under serial bus controllers.

I have reported to lenovo who agreed it seems to be a hardware failure and then graciously offered to fix it for appx 400 dollars. >:/

Re: Yoga 2 Pro Webcam and Screen issues

Welcome to the Forums Dsay.

 

The issue that your having is most likely the one discussed in this article.

 

If the problem remains, consider going back to Windows previous version by doing a Refresh or Reset to isolate any issues on the OS level.

 

Update us how it goes.
