did it have that problem all the time or is it just happening now?If that's the problem directly after install, I guess something went wrong during the install process. So the only solution (i can think of) is reinstalling and hoping it works then.If that is not the case... I have never seen such error before

Try updating Fedora through their update utility - I don't know the exact location of the patch - but if you do a systemwide update this problem is known to go away.

As I said, this is a known problem - check this thread: http://forums.xisto.com/no_longer_exists/

How old is the computer ???

there are 2 protocols for all power related tasks, ACPI and APM.
ACPI is new and replacing APM, Some older machines support APM and ACPI, but computers from around when ACPI was newish, especially laptop's tend to have very buggy ACPI bios's.

You used to be able to fix this by forcing the kernel to use APM instead of ACPI, but i dont know if APM support has been dropped all together yet.

what kernel version are you using ? (the command "uname -a" wil tell you )

If that's the problem directly after install, I guess something went wrong during the install process. So the only solution (i can think of) is reinstalling and hoping it works then.

unless you have proken somthing, or installed from dodgey scratched disks, then re-installing is very unlikel;y to help.

im betting its just a buggy bios disagreeing with that particular kernel version's acpi calls.

maybe update the kernel, or if you have the knowhow, compile a kernel yourself.

if you have ever read through kernel documentation, your wouldnt believe how many tweaks there are for buggy bios chips.
