Comment 31 for bug 70739

Last weekend I installed Ubuntu 6.06 on this 770E. I can tell you how I dealt with the fan. This was worked out a year or so ago on a Vector installation which also would not start the fan.

1. force acpi on by editing "acpi=force" to the end of the kernel line in /boot/grub/menu.lst.
  My kernel line looks like:
kernel /boot/vmlinuz-2.6.15-29-386 root=/dev/hda2 ro acpi=force
I took out the "quiet splash" parameters so I could watch what's going on at boot time. Beware of automatic system updates rewriting the menu.lst file and erasing your change.

2. Add the line "echo 0 > /proc/acpi/fan/FN00/state" to the end of /etc/rc.local file.
Reboot and the fan will be running continuously but at a almost inaudible slow speed. It starts up about time the desktop is loaded. Crude fix but good enough for me.

BTW I also have a 770Z and the fan works automatically on it.

Now if I could only get the sound to work.....
