No change after BIOS update. (which seemed only a security release; not
sure why you suspected that.)

I can't reproduce what happened in the past in more detail.
Here's what happens now:
After unplugging the external USB camera which I've now attached,
running cheese gives stderr (/stdout):
$ cheese
libv4l2: error setting pixformat: Device or resource busy
libv4l2: error setting pixformat: Device or resource busy

Title:
integrated web cam stopped working suddenly
Status in linux package in Ubuntu:
Confirmed
Bug description:
I'm on a Lenovo X230T running Ubuntu 14.04 and I regularly video chat for
work.
2.5 weeks ago, my camera didn't come on during google chrome google video
chat.
It still worked when I ran cheese.
Then, it stopped work under cheese, g-chat, or skype. It didn't work even
when I booted into 14.10 or 15.04.
Then, a week ago, after another update, it began working normally again.
Yesterday, during a gchat , my video suddenly went off and now the integrated
camera doesn't work again under guvcview or cheese or etc. An external camera
works.
Once again, this problem is consistent across operating systems.
