[Bug 1340376] Re: [Lenovo ThinkPad Edge E540] Suspend Failure


Jörn Horstmann, as per http://support.lenovo.com/us/en/products/laptops-
and-netbooks/thinkpad-edge-laptops/thinkpad-edge-e540 an update to your
computer's buggy and outdated BIOS is available (2.18). 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, and the information above is provided, then
please mark this report Status Confirmed.

Thank you for your understanding.
