[Bug 952563] Re: blank display on thinkpad x201 after resume from suspend


Martin Pool, as per http://download.lenovo.com/express/ddfm.html an
update is available for your BIOS (1.40). If you update to this
following https://help.ubuntu.com/community/BiosUpdate , does it change

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.

  [Lenovo Thinkpad x201] blank display on after resume from suspend

Status in “linux” package in Ubuntu:

Bug description:
  same hardware as bug 830355:

  this seems like a recent regression in Precise (maybe between kernel
  -16 and -18):

  after coming back from suspend, the internal laptop display is backlit
  but blank.  switching consoles, etc, doesn't help.  it does reboot on
  ctrl-alt-delay and there are blinks of wlan activity so I think it did
  wake up.
