Benjamin Tegge, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (2.57). 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 just provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** This bug is no longer a duplicate of bug 1098216 Regression in brightness control on Lenovo Thinkpad X230 (+tablet) and X1 Carbon ** Summary changed: - Backlight control via fn-keys is stuck in certain ranges + 8086:0166 [Lenovo ThinkPad T530] Backlight control via fn-keys is stuck in certain ranges ** Tags added: bios-outdated-2.57 ** Changed in: linux (Ubuntu) Importance: Medium => 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/1173984 Title: 8086:0166 [Lenovo ThinkPad T530] Backlight control via fn-keys is stuck in certain ranges To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1173984/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
