1. Summary of standard
======================

Here is a brief high level summary of the standard for PNP0C32. See
https://archive.org/details/microsoft-acpi-dirapplaunch for the full
standard.

PNP0C32 devices are "Direct Application Launch" buttons. The idea is that
they should work while the laptop is in various sleep modes (or even off).
The Z830 does not support waking from any sleep mode using these buttons,
it only supports them while it is awake.
Hi

I might be way off here, but could it not be that one has to enable/allow
the device to be able to wake the system up? Or did you test it on windows
as well and it did not work there either?


Regards,

Each PNP0C32 device represents a single button. Their meaning is completely
vendor defined. On Windows you can either:
* Make them launch an application when pressed (defined in the registry)
* Or an application can subscribe to specific Window messages to get
notified when they are pressed (this is how they are used by the Toshiba
software).
