Re: ACPI Problem: acpi_tz0:_TMP value is absurd

2008-03-12 Thread B J
I located a file for upgrading the BIOS for my Compaq
machine but it requires Windows to install it.  I
deleted the Windows that came with the machine several
months ago, so, for now, that option is out.

I created a file with the following commands:

sysctl hw.acpi.thermal.user_override=1
sysctl hw.acpi.thermal.polling_rate=1800
sysctl hw.acpi.thermal.user_override=0

and run it right after logging in as root using:

source 

where  is the file name.

The message:

acpi_tz0: _TMP value is absurd, ignored (-269.8C)

still appears, but not as often.  I could, of course,
adjust it later if temperature might become a problem
but, for now, the machine isn't on long enough for
that to be a concern.  It still doesn't fix the
problem of an incorrect temperature, but at least I
can read my monitor without it being cluttered with
those messages.

ACPI Problem: acpi_tz0:_TMP value is absurd

2008-03-06 Thread B J
A few weeks ago, I upgraded my Compaq Presario desktop
machine from FreeBSD 6.2 to 6.3.  I soon noticed this
message on the screen.  Apparently, the system is
measuring the temperature of absolute zero.

At first, I thought it to be an installation error on
my part, but reformatting the hard drive and
re-installing 6.3 didn't change anything.  This
message still appears in 7.0.

I installed 6.3 on a Thinkpad laptop but there doesn't
seem to be a problem with that machine.

A search through Google showed that other users are
having the same difficulty but I haven't found a
solution yet.  It's quite frustrating as there doesn't
seem to be a file which I could edit to reset ACPI,
either is there anything in the desktop machine's
BIOS.

Does anyone have any suggestions?  Thank you.

BMJ
