I've had this laptop running for a couple of months without shutting down and it doesn't have a problem. The only time that I do shut it down is when I'm working on site (which I'm doing now). So I only shutdown the laptop while traveling. When I came across suspend2 (and later swsusp), I was excited that I didn't need to restart all my applications when leaving the place of work and coming back. But After being on site for several days, and using the suspend to disk, I get a hot CPU. But when I've been on site while shutting down normally when I leave then I don't have a problem. > > > > P4 has thermal protection, so you are actually safe. > > > > Yeah, but still, the keyboard gets pretty hot too, and I'm actually more > > worried about damaging something that is close by than damaging the CPU > > itself. > > If you damage something, machine was misdesigned in the first place. agreed, but you never know ;) This laptop is currently my lifeline :) > > cat we get contents of /proc/acpi/thermal*/*/* ? I'm running after a poweroff (left it running over night in the hotel, and I'm still in the hotel). $ grep . /proc/acpi/thermal_zone/THRM/* /proc/acpi/thermal_zone/THRM/cooling_mode:<setting not supported> /proc/acpi/thermal_zone/THRM/cooling_mode:cooling mode: passive /proc/acpi/thermal_zone/THRM/polling_frequency:<polling disabled> /proc/acpi/thermal_zone/THRM/state:state: ok /proc/acpi/thermal_zone/THRM/temperature:temperature: 48 C /proc/acpi/thermal_zone/THRM/trip_points:critical (S5): 88 C /proc/acpi/thermal_zone/THRM/trip_points:passive: 81 C: tc1=4 tc2=3 tsp=100 devices=0xcf6c2338 Note thermal_zone/THRM was finished with bash tab completion so they are the only things that match the above glob expr. > > > $ sudo modprobe ibm_acpi > > $ ls /proc/acpi/ibm/ > > bay bluetooth driver led thermal > > beep cmos hotkey light video > > > > No fan there > > Does ibm/thermal work? $ cat /proc/acpi/ibm/thermal temperatures: not supported I guess not. > > Seems like fan is completely controlled by hardware.

It does look like something isn't setting up the ACPI power properly on resume, and that the CPU is probably in a busy loop while the machine is idle. Just a guess. Thanks for the support, -- Steve
