Hi,

I have two more problems (kernel 2.4.11.7, intel based notebooks), with buttons:

- HP nx7000:

suspend to ram works. To wake the computer up I have to press the main power button. The computer wakes up. But as soon as everything is restored the ACPI routines detect that the power button had been pressed (the one to wake it up) and act as if the power button was pressed: The linux is shut down (halt), which is obviously not what was expected.

- MSI S260:

The S260 has three buttons: Power button, Lid button, and Sleep button (Fn+F12 "Zz"). /proc/acpi/button says that all three buttons are recognized under ACPI. Power and Lid work, but when the sleep button is pressed just nothing happens. No log entry, no event, the acpid does not even wake up.

Any idea? (under WindowsXP it works...)

regards
Hadmut

You have to edit your acpid scripts(the one which handle the power button and the sleep button)
Method A is to disable any actions done on power button events. Method B is to create some marker in the suspend script, e.g. a file in /tmp or /dev/shm, before suspend. The power button handler checks for this file. If it's there it delets it, otherwise it shuts down the system

No Idea here. Sorry. Broken DSDT?
