how to get Fn key working on compaq 2100/2110

[David Cougle]

I read on another mailing list that acpi patch allowed fn key to work in 
linux for another compaq, I was wondering if it's possible to get it to 
work, since fn+ a few function keys has suspend, changing of brightness, 
etc.

So, what's your question? Have you tried the ACPI patch?

I have already answered.  If you see events via
cat /proc/acpi/event
then your laptop can not handle what you asked for.

But if you enable APM instead of ACPI, then there is
good luck that actually your laptop will generate a
SMI, then the BIOS will get the info that the sleep
key was pressed, and enter hibernation, but you may
have to config your BIOS accordingly.

Re: how to get Fn key working on compaq 2100/2110

[Mr. Mailing List]

button/power PWRF 00000080 00000002
button/lid LID 00000080 00000004


does that mean an event is button/lid or button[
/]lid?

also, i get no response for 
fn f12, which is supposed to suspend.
fn other acpi keys work(i can change the lighting of
screen)

also, anyone have a script that for lidbtn.sh would
call that sleep.sh script written (sleep.sh start on
go to sleep, skeep.sh stop on resume)?

Re: how to get Fn key working on compaq 2100/2110

[Mr. Mailing List]

What I am asking is, how do i see if the hardware
supports it?  I know some people have laptops that
bypass the kernel and put it in hibernate with certain
keystrokes.

acpid will only do (amongst other thinks like perhaps unloading
modules, etc.)
echo -n 3 > /proc/acpi/sleep
when it detect the correct event via
/proc/acpi/event

via an external script if you press the sleep button.

You still have to write the shell script called by acpid, if
none are already done, or if the distributor have not provided
one.

Some people may want to replace the echo stuff via for
example a '/sbin/shutdown -h now'


For your second question, you first have to shutdown acpid.
Then do a 
cat /proc/acpi/event

By pressing the power button, or the sleep button, etc., you should
see those events.  acpid will do exactly the same, just that when
it look those events, it will take appropriate actions by calling external
scripts.

Is this to say that with 2.5/2.6 my Compaq 2100/2110 will bypass kernel
and suspend to ram? How do I see if it supports that?  I am running
acpid.

S3 (aka suspend to ram) is not supported in Linux 2.4, but even
though it was the case, you have to install a little daemon called
acpid.

In all case, you can test if at least this key work by
cat /proc/acpi/events
then press fn-suspend and see if an event is recorded.
Then, via acpid, you can actually do what you want, by
writting a little shell script in order to handle this key.

I had a patch one year ago.  But it was really too buggy.  I even
don't know if it worked properly due to lack of hardware...
Anyway, even if that patch worked, all the power management
of the devices in linux 2.4 in general have to be rewrotten.

I don't think the cost of the time of this rework for 2.4 will be really
usefull, since linux 2.5 have already a framework for this purpose.
And this work will be too oriented to developpement, not improving
things or write a new driver, etc.

cat /proc/acpi/sleep
S0 S3 S4 (swsusp) S5

I just have heard of people who are able to skip past kernel and force 
suspend to ram.
was wondering if i could do this.

nevermind, it works, but fn plus suspend key does nothing.
does this mean my compaq 2100/2110 does not have suspend to ram?
