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. >Since the above code is commented out, you can just use /etc/devd.conf to >look for Thermal events of type 0x80 and then call a script that evaluates >sysctl hw.acpi.tz0.temperature and then call halt -p if it exceeds some >value. We pipe many ACPI events to usermode through devd(8). 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. -- Rob | What part of "no" was it you didn't understand? _________________________________________________________________ Express yourself with cool new emoticons http://www.msn.co.uk/specials/myemo
