hi i musing fedora 7. the problem is dat each time i shut down my laptop all running daemons are shut down one by one and the screen displays it one by one and at the end SYSTEM HALTED but the hard disk and monitor remain on . how can i cause it to turn off completely.

Check your BIOS. In some computers whether the peripherials are powered off is a BIOS option.

On a couple of my (old) systems I had to manually modprobe apm before that worked. Then I added "apm" to /etc/modules so it would be loaded every boot.

i checked but there is no module named apm?????wt to do now???????

Definitely check the BIOS for the APM/ACPI settings. If it is not set properly, then the software shutdown option will not be able/allowed to turn the machine off.

You can add 'acpi=force' to your kernel parameters. If you use GRUB to boot, edit your /boot/grub/menu.lst (or /boot/grub/grub.conf) to add that to the 'kernel' command like this:

kernel /vmlinuz-2.6.8-2-686-smp root=/dev/hdc3 ro acpi=force

Of course your 'kernel' command will be different: whatever it is, just add 'acpi=force'.

To be safe, you might try this:

Boot your machine. When the boot menu comes up, press 'e' to edit your GRUB script. select the 'kernel' line in the script and press 'e' to edit it. Add 'acpi=force' at the end of the line and press enter to accept the change. Finally, press 'b' to boot. That change will not be permanent, so you can't screw up anything. After it boots, shut it down normally and see if it works like you want it to. If it does, reboot and make the change permanently by editing /boot/grub/menu.lst.

sorry dear i tried it, i m using kernel xen and module vmlinuz, tried to add acpi=force at the end of kernel line but it didnt work
