System info: - Lenovo Ideapad U330 touch - Slackware 14.1 64 bit - vanilla linux kernel 4.3.0 from kernel.org Problem: 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.
Comment 2 Ansa89 2015-11-09 08:16:28 UTC
Oh ok, sorry for the mistake. Tahnks.
Comment 3 Ansa89 2015-12-27 14:02:20 UTC
The problem persists also with kernel 4.3.3.

System info: - 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.

Confirmation. - 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. Suggestion: - 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: https://patchwork.kernel.org/patch/9530859/ Tested on my Ideapad Z580. It works fine and squelches the log messages.

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.
Comment 10 Zach Ploskey 2017-01-29 21:41:17 UTC
The patch was merged and should be in kernel 4.10.
