Problems with battery charging
 
Good everning,

I have the next problem with my Asus EEE PC 1015BX which works under
Debian Wheezy AMD64.
When it is running only on battery power or when it is running from
electrick network with full battery I have no such problem.
But when its battery is charging the kernel send the next strange
messages many, many times:
kernel: [12434.534788] asus_wmi: Unknown key 57 pressed
kernel: [12444.458087] asus_wmi: Unknown key 58 pressed
When I can see those messages sended in my console the pic of
xfce4-power-manager 1.0.11 under X11 (xfce4 v. 4.8.0.3) flashes many
times (changing image from icon "battery is charged" to icon "battery is
discharged" and back).
In this time my mouse under X11 is hanging until the time when those
kernel messages will be stopped. So, it is impossible to work in that time.
What is this and how I can fix it?

Problems with battery charging
 
Ivan,

I don't have your laptop brand and never had your problem, but just a few quick shots:

asus_wmi seems to be the keypad backlight kernel driver.

Old piece from 2011: http://lkml.indiana.edu/hypermail/linux/kernel/1102.3/00970.html

I don't see how the wmi driver should be related to battery charging. Maybe it's rather random that the kernel message gets triggered.

Make sure your power connector is not flaky, or the supply adapter is working correctly. Try a replacement one (no need to buy, only for testing, maybe from a friend ?). Also check the battery connectors, and make sure that it's generally healthy.

If there are any (non-character) function keys then make sure the keys keys aren't flakey, like maybe dirty underneath, or simply damaged. Especially if you poured out your coffee over the keypad...
The touchpad could be flaky too, sending random input triggering some desktop shortcut function.

Counter-check with a different kernel version.

If you compiled a custom kernel you could disable the wmi driver. (Or is there a way to disable it at boot time, by boot options, for every kernel ? Dunno.) But as i said, i can't see the connection, and that should also only just clear the error message, not the problem.

This sounds like a bug in the ACPI handling of your laptop. My guess is that
those keys are meant to be the ACPI system telling your OS that it's
discharging (and that some stat is different). Make sure your BIOS is up to
date, and filing a bug may be in order.

Matthew

Probably it is.

`dmesg` does not curse the BIOS, as can I see:

I filed it: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=697175
They think that it is an adapter problem... Probably, but it seems to me
that I have problems with compatibility between my hardware and software.
Probably, it needs to me to try upgrading to sid?

I've had similar problem with my dell laptop about a year ago. Turned out to
be a bad power source - replacing it fixed the problem.
