[Kernel-packages] [Bug 974455] Re: [Lenovo IdeaPad U300s] 't' key sends Hiragana-Katana
Thank you for your update Christopher. I worked around the problem by draining the battery, as described in more than one post above. This was many months ago, and since then I've not had the problem again. I won't be updating my BIOS any time soon. -- 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/974455 Title: [Lenovo IdeaPad U300s] 't' key sends Hiragana-Katana Status in “linux” package in Ubuntu: Incomplete Bug description: Since booting today, my laptop's 't' key (physical) does not function correctly. Instead of sending the correct keycode, it sends Hiragana-Katakana. I use a dvorak keyboard layout, so it ought to map to 'y' for me. jpds reports that cparrino has had the same issue on nearly-identical hardware, and that the key also does not work in grub. He also provides this work-around: $ xmodmap -e keycode 101 = t Which only works in qwerty. Use keycode 101 = y for dvorak.

[Kernel-packages] [Bug 1253951] Re: Intel wifi power save polling (PSP) causes connection issues with some access points
I haven't kept accurate enough logs. I switched router at roughly the same time as a dist-upgrade. The blog post which led me to fix this problem is dated 2012. It might be a while before I get around to trying the kernel but will update bug when I do so.
