[Bug 974455] Re: Lenovo u300s 't' key sends "Hiragana-Katana"
Robert, I don't know how much of this is software and how much of it is hardware (or maybe a combination of both) but consider this: I got the U300S in approx November of 2011, by February of 2012 the hard drives had died and had to be replaced. In approx September of 2012, the t-key issue had spread to the function keys, to the touchpad and eventually no BIOS flashing or anything could help. I took the laptop in for repair in October, a couple of weeks after reporting some success on this bug discussion. Lenovo replaced the entire keyboard and touchpad, plus said they also replaced the internal battery charger and the USB3, even though neither of these had caused me any problem. I was happy man until a few weeks ago. Then this: first, I noticed the loudspeakers weren't working, but since I don't use them I couldn't be sure how long it had been, the sound was fine with a headset, for about a week, when that also went south. Then I lost the touchpad again, for a few hours, and then the delete key is now completely gone. In the meantime the USB3 (which had been working 100% until Lenovo replaced it, reporting problems in their tests) started to work only about 50% of the time (2 insertions for 1 detection). I'm taking it to repair for the third time tomorrow. So bottomline: there's a very serious issue inside, probably cables improperly connected and shorting and damaging the hardware. For some reason there's an interaction with Ubuntu and/or the sleep mode / battery charge. But the bottomline is: it's rotten inside. So if you have a warranty, get it all fixed by Lenovo and think twice next time you buy a new laptop. -- 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
[Bug 798023] Re: apt-get update fails with error 416 Requested Range Not Satisfiable
precision: my comment above is not clear enough, apologies. 1. removing the partial lists didn't "solve" the warning message, but removing all the lists did. 2. shouldn't one expect that "purge"-ing muon would remove these lists? 3. after purging, cleaning, installing again, then removing the lists, my list of "software sources" was still present in muon, before a restart (not sure if they would have been cleared after a restart because I did not restart). I'm on kubuntu 10.04. hope this helps a little.

I guess I must have been experiencing a similar problem. However, I removed all the lists, not just the partial lists, they were rebuild automatically by muon after "check for updates", and no restart needed as mentioned above: sudo rm -rf /var/lib/apt/lists/partial/* sudo rm -rf /var/lib/apt/lists/* Note that the following was of no help whatsoever: sudo apt-get purge muon sudo apt-get clean sudo apt-get install muon -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/798023 Title: apt-get update fails with error 416 Requested Range Not Satisfiable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/798023/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Tim, I think I may also have uninstalled and reinstalled the wireless drivers, before toggling the wireless in the BIOS (using the latest update from the lenovo drivers website)... good that you got the letters back, The problem is almost certainly caused by a bad interaction between the sleep-mode /dual-boot-mode when the wireless switch is off. -- 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
[Bug 974455] Re: Lenovo u300s 't' key sends "Hiragana-Katana"
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

In my previous comment I seem to have mixed up the bios references 56cn43ww and 56cn38ww, I have flashed back and forth several times between them to no avail.

[Bug 974455] Re: Lenovo u300s 't' key sends "Hiragana-Katana"
I have just joined the club. I've had my Lenovo U300S for nearly a year now and only yesterday, for the first time, have I experienced the bug. I have a dual-boot windows/ubuntu. The bug is definitely in the bios since it affects both os. In my case, the letter t is remapped to F9 (because I'm on dvorak, it's actually the letter y). The same remapping on windows and ubuntu. As a workaround, I have remapped the keys. On Windows I use Sharpkeys, a simple freeware which modifies the registry. On Kubuntu, I have used $ xmodmap -e "keycode 75 = y" The problem started after ... I flashed the bios. I flashed the bios because all of a sudden some of the function keys started to go. I couldn't access most of the function keys between F7 and F12, including the wireless switch and the brightness keys. After flashing the bios, the function keys started working again. But that's when I lost the letter t. And I seem to have lost it for good. I had flashed with the latest bios, 56cn38ww. After detecting the problems, I downdated the bios, but that didn't help. I still have a windows partition so I flashed the bios within windows. In case you're wondering, to downdate in windows, you can execute a bat file with the following line of text: C:\BIOS\56cn43ww\WinFlash.exe /NODATE C:\BIOS\56cn43ww\56CN43WW.ROM where you should check that the paths are consistent with your setup. Now for all intent and purposes my laptop is working since I have remapped the t-key and I don't care much for F9. But I don't like it no I don't Mr Lenovo! I'm going to try to drain the battery. I'll get back to you if I learn anything interesting. -- 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
