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.

Randallw, thanks so much for the update. Since things appear to be

Hi Leann,
Actually, now that I have discovered what is going on, I don't think my
problem is a linux/ubuntu bug. It is caused by a broken acpi DSDT on my
computer. (I even paid to upgrade my bios before finding that article,
and it made no difference). It seems that a broken DSDT is not at all

circumstances, directly cause a loss of user data".

I am also having this problem in Gutsy (also in Feisty) so the problem
has not gone away. I was having overheating problems and had to turn off
the acpi (and apm) service in the "services" administration menu for the

I've tested with the latest kernel from feisty 2.6.19-5 which I believe

problems, namely:

It may be, but I don't think so. "acpi -t" doesn't trigger the fans on
