Update on my previous report: Draining the battery (the old fashioned way) worked for me. All my keys came back, even the letter t.
However, within a few hours, the problem returned. And here is what I believe happens: Recall that I have a dual-boot windows-kubuntu. The problem occurred after I disabled the wireless from within windows (using the function key FN+F7 and clicking the Lenovo pop-up gui), then having disabled the wireless went into kubuntu, went back into windows and the special function keys were gone. I recall doing something like that around the time of the first problems. To be clear, the letter t was still there, but the function keys from F6 to F12 were gone. The problem stumped me for a while. I reinstalled a bunch of drivers and flashed the BIOS, to no avail. I noticed that my webcam was gone too. I started suspecting a hardware problem. After all, my ssd died after only one month, so the machine is fragile. So to sum up: within a few hours of fixing the problem, I was in trouble again: no webcam, no wireless, several function keys dead. Then I got an idea: I disabled the wireless from the BIOS (the wireless was shown as enabled, so I didn't immediately think of fiddling with that). Then I disabled the wireless, went into windows, then went out again re-enabled the wireless in the BIOS, went back in and voilà! Not only was the wireless back on but the function keys started working again. It took me a little while to get the webcam to work because I hadn't realized that FN+F9 is an activating shortcut, but I did figure it out after a while. And suddenly everything was back to normal (except the time wasted, which is lost forever). Unfortunately none of these actions were performed under controlled- experiment conditions. If I have learned anything though, it's this: draining the battery may get your letter t back, disabling and re-enabling the wireless in the BIOS settings may get your function keys back, and avoiding launching Ubuntu with the wireless disabled can save you some headaches. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974455 Title: Lenovo u300s 't' key sends "Hiragana-Katana" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
