Nicolas K, as per http://support.lenovo.com/us/en/products/Desktops-and- all-in-ones/Lenovo-A-Series-all-in-ones/Lenovo-A540-All-In- One/F0AN?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an update to your computer's buggy, insecure, and outdated BIOS is available (O14KT19AUS). 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. Thank you for your help. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1651294 Title: [Lenovo IdeaCentre A540] Doesn't poweroff on shutdown Status in linux package in Ubuntu: Incomplete Bug description: After switching from Lubuntu 15.10 to Lubuntu 16.04, I cannot shutdown my (Lenovo A540) computer anymore. The Lubuntu logout screen hangs indefinitely and doesn't react to most keyboard combinations. I thus have to press the power button for a few (~5) seconds in order to shut it down. I don't have this problem with Windows 10 (dual boot).
