Using any means whatsoever, I would like to be able to turn off the screen
and possible also the harddisk of my laptop so that I can just listen to
music without the screen powered on using up laods of battery.

As I see it there are various different options for this:

There is the Fn + D shortcut which talks to the BIOS (unique to the laptop)
Which works when booting up the BIOS and work in LILO, but the moment
Linux is booting it is not recognised anymore.

Then I could think of DPMS in xorg.conf, and I've set a timeout for the screen,
but I've not set anything else, and it is not interpreted.

ACPI (from the Laptop Battery optin in KControl) doesn't get picked
up when I set it to happen when I close the lid (although it does recongise
that the lid is closed). Interfacing with ACPI through KLaptop doesn't
work either.

In the console I've tried "apmsleep + 0:01", but it says there is no APM
suport in the kernel, although I installed the bareacpi.i kernel

Please help me save the batteries!

Thanks,
Riddick

I am running OpenSuSE and when I close mine it goes into standby. although standby also shuts off XMMS so the music I was listening to goes off.


SuSe uses a powersave daemon as part of the acpi. There is even an app in KDE called Kpowersave.

Whatever you do, don't choose suspend to disk. Hehe it copies everything to swap then shutsdown he harddrive, and the only way to restart is by hitting the power button. And may or may not result in corrupted data.

The best I have been able to do is either get the a blank screen saver or suspending the system. Hopefully someone knows how to fix the problems.

Ok - can you tell me:

What kernel you have?
Do you have ACPI on?

Is KPowerSave for SuSE only?

yes an answer would be excellent
