Re: APM support not found in Kernel ?



I appended "acpi=off apm=on" to the kernel line but still received the message that APM is not supported by the kernel.

I also noticed that, when I tried to invoke apm, my fan never stopped running. Thanks to a previous message, I know my notebook (HP ze4560) does not provide apm. (Does any one think a newer BIOS may help this?)

So I went back to acpi. The command "echo 3 > /proc/acpi/sleep" put the system to sleep. But, I was not able to wake it up. I had to do a hard reboot.

Tough luck! But my wholehearted thanks for the discussions and helpful comments.

Mine is a "Compaq Presario 1277" laptop, How can i determine if this
requires a ACPI or APM to have the fan running ?



You're running acpi now. Does the fan work? If so, you're done.


If not, edit /boot/grub/grub.conf (make a backup copy first). Find the
line or lines that start with 'kernel' and add "acpi=off" (without the
quotes) to the end of those lines. Reboot. Now you will be running
apm. If the fan works, then apm is probably what you want. If the fan
still doesn't work, I don't know what to suggest.

By the way, I learned all this by searching and reading the list
archives. It's fun--I recommend it. Find a link at the end of every
list message, or go to

http://marc.theaimsgroup.com/?l=fedora-list&r=1&w=2

where some good people maintain another archive (with a more reliable
searching tool) of the list.

good luck,
Matt
