This bug occurs when shutting down. The computer will exit the OS but the power and wireless lights will remain on, and the screen will remain on, but black.
The culprit is a bug in the snd-hda-intel module that controls the sound card in the EEEPC. There are a number of ways to fix this, however, the general approach is to remove the module from memory just prior to shutdown.
This can be fixed by re-installing the bios from “Add/Remove Software” in Xandros.
If the BIOS re-install doesn't solve the problem, you can edit the file /sbin/fastshutdown.sh and add the line:
rmmod snd_hda_intel
above the line
/usr/bin/killall --wait usbstorageapplet
There are a number of different approaches to this. The first is to edit /etc/init.d/halt and add the following line to the beginning of the do_stop function:
do_stop () {
rmmod snd-hda-intel
if [ "$INITHALT" = "" ]
...
The second is to add rmmod command to the end of /etc/default/halt:
rmmod snd-hda-intel
Basically you need to read the documentation for your distro and place the rmmod command mentioned above in the appropriate place so that the module is removed prior to OS attempting the halt or reboot the machine.
