I can wait - the benefits of ACPI more than make up for such a minor 
problem.

Well, it's been a while since I last saw this happen - I've had it disabled 
for some time now (since ACPI started working on the laptop in fact).  There 
was the standard ACPI message printed, with a message about thermal, just 
before the poweroff so I'm confident it's not the BIOS.

Re-enabling thermal support didn't cause a poweroff last thing yesterday in 
the hour or so before I left work.  Before it rarely ran for more than 15 
minutes before a spurious reading caused a poweroff.

I'll have a look at that - thanks.  Out of curiosity, what's the number 
reported there actually mean?  Yesterday my laptop was reporting numbers of 
around 3350 there, so I'm guessing it's not a literal value in any scale I'm 
familiar with.
