Tom Fifield, as per http://support.lenovo.com/us/en/products/Laptops-
and-netbooks/ThinkPad-X-Series-laptops/ThinkPad-X250? an update to your
computer's buggy and outdated BIOS is available (1.17). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

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:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

  firmware iwlwifi-7265-ucode-25.228.9.0 on kernel 3.16.0-38-generic
  #52~14.04.1-Ubuntu, the error " Microcode SW error detected.
  Restarting 0x2000000." is received, the card crashes and can't connect
