This stuff seems to work very well, so...
<code>
~ cp /sys/firmware/acpi/interrupts/gpe13 /pathtobackup
~ crontab -e
</code>
Add this line, so it will be executed every startup/reboot:
<code>
@reboot echo "disable" > /sys/firmware/acpi/interrupts/gpe13
</code>
Save/exit. Then, to make it work also on after wakeup from suspend:
<code>
~ touch /etc/pm/sleep.d/30_disable_gpe13
~ chmod +x /etc/pm/sleep.d/30_disable_gpe13
~ vim /etc/pm/sleep.d/30_disable_gpe13
</code>
Add this stuff:
<code>
#!/bin/bash
case "$1" in
thaw|resume)
echo disable > /sys/firmware/acpi/interrupts/gpe13 2>/dev/null
;;
*)
;;
esac
exit $?
</code>
Save/exit.
Done (Under Ubuntu 12.10).
