James Ferguson: >"Description was updated to be totally inaccurate."
The original Description you inputted originally was precisely: "The laptop appears to suspend/resume fine stand-alone, but if a DisplayPort monitor is connected, it does not." Please take care when creating bug reports going forward, so folks don't become confused as to the exact bug reproduction scenario. >" To suggest disconnecting the monitor as a workaround is somewhat unhelpful" A WORKAROUND is not a suggestion but a fact, and helpful for those folks who want to suspend now while waiting for a fix to be developed. Despite this, as per http://support.lenovo.com/us/en/products/Laptops- and-netbooks/ThinkPad-T-Series-laptops/ThinkPad- T450s/20BX?tabName=Downloads&linkTrack=Mast:SubNav:Support:Drivers%20and%20Software|Drivers%20and%20Software&beta=false an update to your computer's buggy, insecure, and outdated BIOS is available (1.27). When you update to this following https://help.ubuntu.com/community/BIOSUpdate how does this improve the situation? 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. Also, you don't have to create a new report. It is most helpful that after 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 how this improves the situation. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.
