A. M., as per http://support.lenovo.com/us/en/products/laptops-and- netbooks/lenovo-z-series-laptops/lenovo-z50-70 an update to your computer's buggy and outdated BIOS is available (29). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 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, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-29 ** Attachment removed: "lspci-vnvn.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1429550/+attachment/4337825/+files/lspci-vnvn.log ** Attachment removed: "version.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1429550/+attachment/4337826/+files/version.log ** 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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1429550 Title: All USB Ports disabled after boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1429550/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
