Comment 6 for bug 1539080

Stéphane Graber, as per http://support.lenovo.com/us/en/products/Laptops-and-netbooks/ThinkPad-T-Series-laptops/ThinkPad-T450s?linkTrack=Homepage:Body_Search%20Products&beta=true an update to your computer's buggy and outdated BIOS is available (1.20). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command:
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.
