OPtions to turn off my Acer 1357LMi
 

Hi, I have an Acer 1357LMi laptop with MKD 9.2 kernel 2.4.25mdk.
Whenever I try to turn off my laptop it reboots after powering down, so I'm force to press power button for 5 seconds.
How can I avoid this?
Here's my lilo conf:

boot=/dev/hda
map=/boot/map
default="2425-5"
keytable=/boot/it-latin1.klt
prompt
nowarn
timeout=100
message=/boot/message
menu-scheme=wb:bw:wb:bw
image=/boot/vmlinuz
label="linux"
root=/dev/hda1
initrd=/boot/initrd.img
append="devfs=mount hdc=ide-scsi acpi=ht splash=silent"
vga=788
read-only
image=/boot/vmlinuz
label="linux-nonfb"
root=/dev/hda1
initrd=/boot/initrd.img
append="devfs=mount hdc=ide-scsi acpi=ht"
read-only
image=/boot/vmlinuz
label="failsafe"
root=/dev/hda1
initrd=/boot/initrd.img
append="devfs=nomount hdc=ide-scsi acpi=ht failsafe"
read-only

image=/boot/vmlinuz-2.4.25-5mdk
label="2425-5"
root=/dev/hda1
read-only
optional
vga=788
append=" devfs=mount hdc=ide-scsi acpi=ht splash=silent"
initrd=/boot/initrd-2.4.25-5mdk.img

Thanks eberybody for your precious help!!!

well i don't know what your typing or what your pressing (cause you didn't say)
but without knowing and just to give a quick solution is to open a terminal and type :
as root

but shutdown -h now it's an alias for halt as far as i know.
Anyway I just go Start----End session--->turn off computer but when it power off it instantly reboots.

SOLVED: changed the line in lilo acpi=ht to apm=on (or acpi=force)
The downside is Laptop Energy Manager is no more available (dunno how you call it in english).
