Laptops :: Laptop computer, fan does not switch on properly

The utility will usually let you back up the current bios; so if flashing fails, you can flash the previous bios back before rebooting.

ok, I`ll go searching for the latest one for my machine. This morning I found the one for the newer 400MHz model and it`s release date was 1999, so I don`t hold much hope for anything newer for the 300MHz I have.

Does the BIOS setup page usually report what release is loaded on the machine? Would a BIOS from 1999 report this info?

I'll be loading this up tonight: ARMADA 1750 6300/T/4000/D/M/1 ROMPaq

My desktop compaq only reports the date; it was from -97 when I got it, and I flashed it to a bios from -99. The boot time nearly cut to half, amazing when they actually update something useful

${color #ddd}Battery: $color ${battery}
${color #ddd}CPU Temp: $color ${acpitemp} degC

Finally got around to this. And I flashed the BIOS to the latest (nov 1999)

Trying a few things.

First, I disabled ACPI in the BIOS. Saw the Battery % for the first time ever. Showed steady 100% with the cord plugged in or not. Didn't see any fan, thermal, battery etc modules get loaded. Fan didn't spin. CPU temperature displayed 0 zero degrees C.

Then I reset the BIOS to use ACPI. Battery % shows nothing just like usual. CPU temperature shows 75C at startup... watching it climb. 6 ACPI modules activated ac, battery, button, fan, processor, thermal.

hmmm... fan never kicked in (like usual).

I have no clue how to use APM instead of ACPI. What's the difference between ACPI and the APIC boot code?

Thanks so far, what can I try next? Remember, this machine runs fine under XP.

Here's what I found when I grepped ACPI dmesg:

Code Sample

What do the <N> numbers signify?

And I finally found the 'state' files Curaga mentioned in the other post. My fans are labelled C102 and C104 (I saw it in dmesg above). When I more state in both folders, I see status: on but fans aren't spinning. I tried:

Code Sample

echo -n "1" > state
to force it on.

as suggested by Curaga... made no difference. Thought maybe I could cycle them off and back on, so I tried "0" instead and it also had no effect. hmmm... I didn't get any errors, and I was using shell as root, but it really seems to me that I cannot change the contents of this file - as if the daemon overrides my changes immediately.

- apm is the power management system that came before acpi. As mentioned, to use it try "acpi=off apm"
