Portege Z930 extra keys and leds

Portege Z930 extra keys and leds

[Enrico Weigelt, metux IT consult]

Hello folks,


does anybody happen to know how to drive the extra keys and leds
of Toshiba Portege Z930 notebook ?

It has two extra keys above the keyboard (right next to the power
button) and some indicator leds underneath the touch panel buttons.

Toshiba originally ships the notebook with some strange Windows software
(for some mysterious "ECO" mode) that reacts on these two buttons and
drives at least the rightmost LED directly - so there has to be *some*
way to control them by software.

When in a terminal (on the console only when /dev/input/event10 -
"Toshiba input device" is opened), both keys seem to generate an "x"
keypress, but nothing coming in in the event device.

Does anybody have an idea how to catch these key press events or
how to drive this myserious ("ECO") led ?


thx

PS: tried on an older 4.14 kernel - haven't had a chance to upgrade
the notebook to something more recent :o

You may want to play with evtest.

And you may want to dump the ACPI tables, I'd expect it would be driven from
there.

You may also want to search drivers/platform/x86 (or something like that) on
the latest kernel...
