Subject: broken power button
Date: Thu, 05 Feb 2004 18:55:58 -0800 [thread overview]
Message-ID: <1076036158.4792.12.camel@tinny.home.foo> (raw)
APM will let me suspend to RAM and restore, but the touchpad is broken
the whole time.
So I'm trying ACPI -- ACPI seems to suspend successfully, but it will
not wake up. I have to unplug the battery and power supply for 10+
minutes to reset it.
I think it's related to the power button. I notice that the power
button does not generate any events via acpid (but if I close the lid,
or press Fn-ESC, then I do see events). However, if I hold the power
button down for 4 seconds, the machine does shut off immediately.
(Holding it down for 4+ seconds while frozen does nothing).
In tracing this further, I noticed that the ASL lists the button 'PWRB',
while ACPI (via dmesg) lists the button 'PWRF'. I think (can someone
clarify this?) that this is the difference between a "fixed hardware
power button" and a "control method power button."
I tried renaming all references to PWRB to PWRF and recompiling, but
that did no good. I think (again, can someone clarify this?) that I
need to set the PWR_BUTTON flag, but I don't know how to do that. There
is a reference to SLP_BUTTON in the dsdt.asl file, but it's in a
comment.
Am I on the right track here?
oh, specs: 2.6.2-rc2-mm1 (ACPI v20040116), Dell Lattitude X200 (P3M
800), patched DSDT to cope with battery issue.
