[Bug 1435070] Re: Thinkpad T550: Broadwell with Intel HD5500 powers off randomly


Shevek, as per http://support.lenovo.com/us/en/products/laptops-and-
netbooks/thinkpad-t-series-laptops/thinkpad-t550 an update to your
computer's buggy and outdated BIOS is available (1.10). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

If it doesn't, 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

For more on BIOS updates and linux, please see

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status New.
Otherwise, please mark this as Invalid.

Thank you for your understanding.

  Thinkpad T550: Broadwell with Intel HD5500 powers off randomly

Status in xorg package in Ubuntu:

Bug description:
  In the first two weeks of owning a Broadwell T550, I have suffered
  about two dozen abrupt power-offs. This has happened:

  a) While resuming from suspend.
  b) While in normal operation and just moving the mouse.
  c) While switching from X to console by pressing ctrl-alt-F1.

  There was no kernel panic, no log files, just an abrupt power-off.

  In conjunction with several other HD5500 issues, I am starting to
  suspect the intel video driver, and have switched to the modesetting
  driver. Setting the Intel driver to use AccelMethod: none made the
  system more reliable but did not eliminate crashes.

  Workaround: Put the following in /etc/X11/xorg.conf:

  Section "Device"
          Identifier "intel"
          Driver "modesetting"
