After touchpad use, immediately my IdeaPad's keyboard and aforementioned touchpad freezes
 
Hello lovely LQ folk! This place has helped me out a ton and I've never contributed back—gotta work on that! But uhh, I need some help first heh.

As the title says, my Lenovo ideapad 300S-11IBR keyboard & touchpad is not responsive. The trigger? Using the touchpad.

I can type forever on the keyboard until I use the touchpad. Specifically, any use will do, from the slightest brush. The mouse will move a little bit too.

Was shelved for a year, working fine before.

What I've tried so far to no avail:
  • Replicated this behavior on clean installs of Ubuntu plus X & L derivatives.
  • Manually updated to kernel 5.2.8.
  • Checked for any BIOS stuff. There's no options relating to the keyboard/touchpad there, nothing else weird in my untrained eyes.
  • This solution to a similiar problem (basically use libinput instead of synaptics).

One thing, I forgot how unfortunately (sorry I hate myself too), but recently I did somehow reenable the touchpad/keyboard by typing some command from stackoverflow. I used the touchpad again and... same issue.

Here's xinput list:
Code:
⎡ Virtual core pointer                            id=2        [master pointer  (3)]
⎜  ↳ Virtual core XTEST pointer                      id=4        [slave  pointer  (2)]
⎜  ↳ USB OPTICAL MOUSE                              id=10        [slave  pointer  (2)]
⎜  ↳ Microsoft Wired Keyboard 600 Consumer Control        id=12        [slave  pointer  (2)]
⎜  ↳ SynPS/2 Synaptics TouchPad                      id=17        [slave  pointer  (2)]
⎣ Virtual core keyboard                          id=3        [master keyboard (2)]
    ↳ Virtual core XTEST keyboard                    id=5        [slave  keyboard (3)]
    ↳ Power Button                                    id=6        [slave  keyboard (3)]
    ↳ Video Bus                                      id=7        [slave  keyboard (3)]
    ↳ Power Button                                    id=8        [slave  keyboard (3)]
    ↳ Sleep Button                                    id=9        [slave  keyboard (3)]
    ↳ Microsoft Wired Keyboard 600                    id=11        [slave  keyboard (3)]
    ↳ Microsoft Wired Keyboard 600 System Control        id=13        [slave  keyboard (3)]
    ↳ Lenovo EasyCamera: Lenovo EasyC                id=14        [slave  keyboard (3)]
    ↳ Ideapad extra buttons                          id=15        [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard                    id=16        [slave  keyboard (3)]
    ↳ Microsoft Wired Keyboard 600 Consumer Control        id=18        [slave  keyboard (3)]
Ignore 18 and 10 as their external devices I'm using ofc.

So... I couldn't find any other thread on the internet about someone having this issue... ugh. I have no idea how all this stuff works with Linux, so pretty lost in what help I should be seeking tbh.

Next is trying a copy of Wins I 'spose (ugh). Before I lose all dignity with that, please tell me why I'm a dumbass and should of provided <x> debug info. Or even a possible solution!

Is it a hardware failure maybe? Would like to confirm that.

Thanks for your time~

Not solved, but I fried a connector from the mb to the battery whilst trying to reassemble the laptop. Oops.

Batteries are too expensive for this rather cheap laptop, so I'm gunna ditch the battery and just use this as a server down the line.

Will post if I do find if it's a hardware issue for sure heh.
