an update is available for your BIOS (56cn38ww). If you update to this,
does it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

Title:
  [Lenovo IdeaPad U300s] webcam stopped working, somewhere around mid-
  March 2013

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Running raring, my webcam on this Lenovo U300s has worked fine, until
  about a week or two before today (today is April 2nd 2013; it stopped
  working at some point in the last couple of weeks). The webcam is now
  unavailable to any tested webcam-using application (Google Hangouts,
  cheese, guvcview, conversat.io).

  Cheese says: ** (cheese:15867): WARNING **: cheese-main.vala:251:
  Error: No device found

  Guvcview says:

  ERROR opening V4L interface: No such file or directory
