Laptop server goes to sleep and will not stay awake


I have an old Acer laptop that I am trying to use as a server for Vortexbox (Fedora distro that turns computer into a media server for use with DLNA and Logitech Squeezeboxes).

Randomly the laptop will go into standby mode and I cannot figure out why. It's very annoying since when the laptop goes to standby the server goes down and all my boxes disconnect. Everything reconnects when I simply press a key on the laptop and it wakes up and the screen turns back on.

Here's what I've tried:
I've tried checking the BIOS for power management settings and there are none.

I think my CMOS battery is fried since the time keeps drifting. I tried to replace it but could not get to the battery (either through the keyboard or the back of the laptop) so I put in a cron.hourly script that would fix the time every hour and it's keeping things on point in terms of the time but the sleep issues are still there (of note the script does not run when the laptop is sleeping). This is my first script ever so I'm a big newbie...

The laptop battery is nonfunctional (I leave it plugged in all the time anyway). Not sure if that has anything to do with it.

I installed FreeNX and NoMachine for remote desktop to Gnome. When I have a remote desktop session open on another computer it SEEMS to last longer between sleeping.

I tried reading about ACPI and sleepstates and I'm totally lost. I downloaded some thing called ACPItool and ran it to get the following output:

[vortexbox.localdomain ~]# acpitool -e

5. USB1 S3 disabled pci:0000:00:03.1
6. USB2 S3 disabled pci:0000:00:03.2
7. USB3 S3 disabled

Ideally I don't know if the laptop can WOL but if not at least having it be on and awake all the time is fine. Any thoughts? I'd rather not buy a nettop to replace my laptop if I can avoid it since it functions well.

Thanks!

try setting sleep to 0 in /etc/rc.sysinit
and try putting this in your xorg.conf
Code:
Server Layout
BlankTime 0
StandbyTime 0
SuspendTime 0
OfTime 0 
EndSection

I looked at the etc/rc.sysinit file and searched for sleep. This is the only reference I can find. Is usleep the same as sleep?

# Now that we have all of our basic modules loaded and the kernel going,
# let's dump the syslog ring somewhere so we can find it later
[ -f /var/log/dmesg ] && mv -f /var/log/dmesg /var/log/dmesg.old
dmesg -s 131072 > /var/log/dmesg

# create the crash indicator flag to warn on crashes, offer fsck with timeout
touch /.autofsck &> /dev/null

if [ "$PROMPT" != no ]; then
while :; do
pid=$(/sbin/pidof getkey)
[ -n "$pid" -o -e /var/run/getkey_done ] && break
usleep 100000
done
[ -n "$pid" ] && kill -TERM "$pid" >/dev/null 2>&1
fi
} &
if strstr "$cmdline" confirm ; then
touch /var/run/confirm
fi
if [ "$PROMPT" != "no" ]; then
/sbin/getkey i && touch /var/run/confirm
touch /var/run/getkey_done
fi
wait
[ "$PROMPT" != no ] && rm -f /var/run/getkey_done


Also I could not find the xorg.conf file. I looked in etc/x11?
