Re: [SLUG] Computer keeps turning itself off.
try: cat /proc/acpi/thermal_zone/*/trip_points to see what temperature the computer will turn off at and cat /proc/acpi/thermal_zone/*/temperature to see the temperature the computer is currently at... That's interesting, I didn't know about those, though I do have a temp monitor on my lappy screen. Any ideas on how to tweak them as I see the critical temp is set at 109C and the other temps at 108C, and during the recent hot weather with no room aircond when running Winders under VMware it would occasionally shut down - yes the CPU fan is running. If I understand what you are saying correctly, I believe you are asking if you could tweak the trip points. The short answer is no, if your computer is overheating, it is overheating. But if you have a problem with your computer overheating, you could use cpufreqd to slow the CPU down if the temperature goes above a certain temperature. That would have an effect of cooling down the machine a bit. You also could use the on-demand governor that automatically switches your CPU from a slow to faster speed based on the demand on the CPU. Since your computer's CPU wouldn't be running at 100% all of the time, this would have a significant cooling effect. This again can be setup with cpufreqd. I use cpufreqd on all my laptops, because I had a problem with one laptop overheating when I was compiling. Howard.

Re: [SLUG] Computer keeps turning itself off.
Is the heat sink properly seated on the processor? I removed a heatsink to clean the blanket of fluff the fan had forced in, then replaced it but had not locked down all the catches properly. It ran for a while then just shut down like the plug was pulled. Restart immediately and it would shut down immediately, restart next day and it would run for 40minutes the first time, the 2 minutes after an immediate restart. Once I had the catches all secured properly it worked again.

That seems to be the widespread consensus, and it does just switch off. The amount of time between being switched on and switching itself off ranges from minutes to hours. It's a P3, and isn't supposed to need a fan. The main fan is working though.

Re: [SLUG] Computer keeps turning itself off.
Have a look at the modules in /lib/modules/2.6.18-1.2849.fc6/kernel/arch/i386/kernel/cpu/cpufreq. One of these are bound to expose control of your cpu's speed over /sys/devices/system/cpu/cpu0/cpufreq/. cpuspeed, powernowd, cpufreqd, etc all pretty much do the same thing in this sys folder to control your cpu's speed given battery, AC, temperature, etc. states. The cpufreq_ondemand, cpufreq_conservative, cpufreq_powersave are frequency governors that set the cpu frequency between the scaling_min_freq and scaling_max_freq values of this sys folder. My guess for the Celeron would be the ACPI Processor P-States driver. but if this doesn't work then one of the Intel speedstep drivers may work. If you get this working you could easily double the battery life of your laptop and probably make it run quieter.

[SLUG] Computer keeps turning itself off.
Hi, I'm using xubuntu via SSH and the computer keeps turning itself off. Sometimes, /var/log/syslog contains a message about terminating on signal 15, but usually nothing. I don't have any genuine clues as to what is causing the problem. Could this be related to power management? How do I check whether power management is on or off, and how do I turn it off? Is there a config file I can edit? Google doesn't seem to want to help me on this one.

Re: [SLUG] Computer keeps turning itself off.
Hi Adelle, Could be just a dud power supply... Also sometimes when bits heat up they expand and a connection is broken, power stops, seen it before. Also (might be a bit obvious but hey...) check that the power cable in the power supply is in properly. Might be only just connecting. Try another cable and another socket. Once had a Kambrook power board that would turn everything off if too much juice was drawn through it. Then it would reset. Also check the power supply connection from the power supply to the motherboard inside the case might need reseating...

The power supply is external, so there is no fan for it. Anyway, it's not hot.
