Losing Power GRX600K

Before anyone asks:  YES I have ACPI installed/in kernel/etc.  YES ACPI
is working.  I assume close enough proof of this is at the end of this
message.


This is getting frustrating.

A) It's not consistent.  B) It appears to be temperature related, but
not necessarily.  C) I've yet to find anything that will actively record
temperature every 5 seconds that actually works.  D) I've yet to get it
to do it in Windows.  E) It has happened on bootup immediately after it
happened in Linux -- implying it's temperature related or something.  F)
Everytime I call Sony about the problem, they say "Oh, you need to reset
your BIOS and it will stop doing that."  I reset my BIOS -- and it stops
doing it for about 4 weeks, then it starts doing it again.  WEIRD!

What is it doing?   It's just powering off, LOSING power, Shutting Down
NON-Gracefully.  I've found I mention this to most people and they say
"Oh, you mean it shut itself down automatically?"  NO!  It LOST power. 
It acts like I Took out the batteries and then pulled the AC adapter out
and POOF it lost power.  I hope that makes sense.

Anyone have any idea what is up or how I can figure out what's going
on?  I am assuming it's temperature related?  It only started doing this
in June (warmer temperatures outside?)  but it always does it when it's
cool in the room from my human perspective.

This is not a good thing (I think).

If anyone has any ideas or thoughts it'd be great -- or how to get Sony
to acknowledge this problem so they'll take it in and fix it.  But I
doubt they'll be able to reproduce it since it's sporadic and happens
maybe once every few weeks -- and usually when it's at rest not
compiling/etc.  Just have email or a web browser open.

Thanks!  Jay

-- I even swapped out my processor from the 2.4Ghz P4 to the 2.0Ghz P4
to see if it was the processor, it does not appear to be.
