Is there a way to turn ACPI or APM on or off from within your BIOS?

Lenovo has lots of IBM info
here.If you didn't go down this path already.
As 'bagger says, perhaps you can use the bios setup.
Older bioses could use PS2 or the tpctl progs.
Kopsis made a .dsl of it some time ago, cant seem to find it in a hurry.
I'm not sure, maybe you can add 'apm' to your append/boot line,
since there is a 'noapm' boot code.

Most laptops have APM/ACPI built into the BIOS with no way to disable it. You can find out if your kernel has recognized the APM support by looking for "/proc/apm". If it's not there, try loading the APM module (sudo modprobe apm). If that doesn't work, you're probably booting with the "noapm" kernel parameter.

If I remember correctly, a frugal-grub install will have a default boot line that includes the "noapm" param. Mount the partition where you did the frugal install and edit "/boot/grub/menu.lst" to remove the "noapm" param from the boot line.

I'm not sure what the default is for a frugal-LILO install but I seem to remember that it preserves whatever parameters you booted with when you did the install. The file "/etc/lilo.conf" is where you edit the boot command. There are probably lots of posts explaining how to tweak LILO settings if it turns out that's what you need to fix.

Thank you all very much. I didnt get a chance to look at it tonight because our power has been out, but I will start looking at it tomorrow and see if I can make any progress. I will let you all know how it goes, or if it doesnt I may ask more questions if you dont mind.

Well I managed to get wmapm.tar.gz working. It will make a huge difference when using my lappy. What I ended up having to do was add 'acpi=off' to lilo.conf. I discovered a message 'apm: overriden by acpi' or something similar. So I believe that acpi must overide apm since it is a newer standard, but acpi was not working for me even though it was in /proc. So after turning off acpi, apm has taken over and now I see apm in /proc. Just thought that I would share some of the details.

My only problem now is I messed something up on my frugal install while I was fiddling with things. My partition which I use for mydsl, home, opt and restore (hda2) is not being mounted automatically upon bootup. It finds my extensions in the partition fine and loads them along with restoring things, but when I go into emelfm or something I have to mount hda2 to do anything. I am not really sure what I did or how to fix it. If anyone has any suggestions for me on this I will gladly except them.
