[frgeek-michiana] Re: Warehouse Report - 7/27/2008

I turned off acpi in vasm, added the following to lilo.conf, ran lilo and
rebooted. However, there is no improvement.

  append = "acpi = off apm = on"

I suspect compiling in a better dsdt table might get the fan going -- it
seems to have worked for others. I won't have time to look at BIOS options
or the kernel config file (if there is one) until Tuesday at the warehouse.

I had the same issue with the N600c I'm using for kiosk development. At the
moment I haven't been running it since it gets so hot, for a while I had a
small cpu fan taped to the side, in addition the keyboard, mouse, and
display shutdown after a while requiring a hard reboot to get the system
back. I think it will work OK as a demo system but it is definitely a Linux
hostile system. From what I understand it was a pretty good Windows system.
On the plus side we could have the worlds first combination laptop/popcorn
popper.

Haven't tried it yet but the above recommends turning off acpi and using
apm.

PS
I should make it Tuesday this week.
