- Lenovo Ideapad U330 touch
- Slackware 14.1 64 bit
- vanilla linux kernel 4.3.0 from kernel.org
When on battery it spams "ideapad_laptop: Unknown event: 1" every 15-20 seconds on syslog.
If you need any other info, just ask.
ideapad_laptop is a platform driver, I'll move the bug there.
Oh ok, sorry for the mistake.
The problem persists also with kernel 4.3.3.
- Lenovo Yoga 900
- Ubuntu 15.10 64 bit
- vanilla 4.5.0 kernel from kernel.org
I get the same message; however, it only happen when changing between laptop and tablet modes. In addition, the scancode for the Touchpad toggle button is not recognized:
atkbd serio0: Unknown key pressed (translated set 2, code 0xbf on isa0060/serio0).
atkbd serio0: Use 'setkeycodes e03f <keycode>' to make it known.
When I do set the keycode, however, the generated keycode is off by eight. For example, if I use "setkeycodes e03f 40", xev shows keycode 48 when the key is pressed/released.
System info :
- Ideapad 500 ACZ
- Ubuntu 16.04 64 but
- Kernel - 4.4 (Ubuntu stock) and vanilla 4.6
I get this message during shutdown and also when I press power key.
Also shutdown and reboot not able able to perform physical/hardware shutown or reboot the laptop although log says shutdown complete or rebooting respectively .
- Lenovo Yoga 900-13ISK
- Kernel 4.8.1
It is consistently the case when swivel the Yoga into tablet mode and getting out of tablet mode.
- Adjust function ideapad_acpi_notify(acpi_handle handle, u32 event, void *data)
- Add case 1: with call to ideapad_input_report(priv, vpc_bit);
It will call sparse_keymap_report_event() and should end up in user-space.
On my Lenovo Ideapad Z580 this is written to the log every 21-23 seconds while on battery power.
Kernel version: 4.8.13

I submitted a patch to make this change here:
Tested on my Ideapad Z580. It works fine and squelches the log messages.

Thanks! I patched my own system exactly like this as well, but didn't find time to submit it.
The patch was merged and should be in kernel 4.10.
