Matteo Dell'Amico, as per http://support.lenovo.com/us/en/products /laptops-and-netbooks/thinkpad-twist-series-laptops/thinkpad-twist- s230u/3347/4hu an update to your computer's buggy and outdated BIOS is available (1.71). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it address the issue?
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. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: kernel-bug-exists-upstream kernel-bug-exists-upstream-4.3 -- 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/1512482 Title: Keyboard and touchpad malfunctioning on Thinkpad Twist Status in linux package in Ubuntu: Incomplete Bug description: I don't know if this is really a kernel bug or if it's any other component, please help me know how I can diagnose the problem better. This is a bug I have been experiencing with both 15.04 and 15.10, while this was not a problem with earlier distributions -- unfortunately, I don't remember which one in particular was actually working. I have a Thinkpad Twist -- a hybrid laptop with touchscreen. The touchpad almost never works (even though sometimes, erratically, it does). The keyboard sometimes stops working, and works again after a suspend/resume cycle. Sometimes it behaves as if a key is stuck. When running xinput --list, I don't see the touchpad. The touchscreen and external input devices connected via USB, however, work fine. I was thinking this was a hardware problem, but on the same machine with Windows the problem does not appear to present itself.
