Okay the bios was updated to 3.21 and ecp to 1.06, for luck the battery seems to have the right security chip and is accepted by the new ecp. But as explained here is the warning from a 3.22 tester and his battery.
http://thinkpad-forum.de/archive/index.php/t-152969.html The brightness bug still exists. It did not appear when booting a live 14.04 LTS system on the machine. ThinkVantage buttons did nothing, not a laptop start, not at bios and not within ubuntu. The required hidden service partition does not exist on my ssd, there is a way to repair but for what is it needed without windows? https://ideasmiths.wordpress.com/2007/07/04/solution-to-lost- thinkvantage-button-access-to-hidden-parition-in-thinkpad/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1455002 Title: Thinkpad x200t backlight settings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1455002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
