FW: Toshiba 2410 & ACPI

FW: Toshiba 2410 & ACPI

[Brad Beveridge]

Hi all, this is my first post.  Firstly - sorry if this has already been
discussed, I searched the archives & couldn't turn much up.  I don't
know if what happened to me is a hardware fault or an ACPI bug :)

Machine : Toshiba Satellite 2410 (I think it's a -404 model) Kernel  :
2.6.1 (unpatched ACPI)

A while ago I upgraded to 2.6.1 (I didn't know I needed further ACPI
patches), and setup all the ACPI stuff so I could play with my laptop's
power management features.  I was pleased to find that everything I
wanted worked : sleep state S3, CPU scaling, backlight control (via
toshiba_acpi driver)

After a couple of days happily entering S3, one day it did not come back
from S3.  So I rebooted & then the laptop hung in the "In Touch with
Toshiba" screen.  I left it off over night & it worked in the morning,
very strange. In the course of my experiments I found
1) If it got stuck in the BIOS screen, leaving it off & unpluged for
more than about 8hrs would fix it.
2) Suspend no longer worked, under ACPI, APM or WinXP
3) It suddenly did work for a couple of days
4) It then stoped working again

The mainboard has been replaced as the local service centre said it was
faulty.  When I got my new main board I monitored the temps that the fan
goes on/off at.  On my broken main board the BIOS was automatically
turning the fan on at 70C and off at 60C.  On the new one it is 55C and
50C - this is just a BIOS setting, but I was previously unaware of it
(and a little concerned by how hot my laptop used to get).

Basically I have the following questions
1) Was the mainboard fault just a coincidence that I was playing with
ACPI and sleep?
2) Is it likely that operating at high temp has caused the original
fault?
3) Can I safely use ACPI sleeping with a ACPI patched 2.6.2 kernel?

Cheers
Brad

Software should not be able to damage hardware. If it is,
hardware deserved it. I'd try again if I were you.
