lumiza, thank you for reporting this and helping make Ubuntu better. As per http://support.lenovo.com/us/en/products/Laptops-and- netbooks/Lenovo-G-Series-laptops/G50-30-Notebook- Lenovo?linkTrack=GPS:Body_Search%20Products&beta=false an update to your computer's buggy, insecure, and outdated BIOS is available (a7cn48ww). 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. Also, 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. ** Tags added: bios-outdated-a7cn48ww ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** 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/1574047 Title: Lenovo G50-30 laptop freezes randomly Status in linux package in Ubuntu: Incomplete Bug description: Keyboard or mouse do not work when the system freezes.
