    First of , I haven't been here a long time. Call it a testament to the Toughbook reliability and my increased abilities. I might actually understand *nix a bit after 25 years :)

    Now the issue:
    grep -iv ': starting\|kernel: .*: Power Button\|watching system buttons\|Stopped Cleaning Up\|Started Crash recovery kernel' \
    /var/log/messages /var/log/syslog /var/log/apcupsd* \
    | grep -iw 'recover[a-z]*\|power[a-z]*\|shut[a-z ]*down\|rsyslogd\|ups'

    ~returns,

    /var/log/syslog:Oct 27 09:38:44 kop-CF-30KQPAQ2M kernel: [ 1026.489987] thermal thermal_zone0: critical temperature reached(106 C),shutting down

    oops...

    Okay, now what ?

    P.S. pics for the hellofit

    Looks like you might be due for a thermal pad overhaul.

    The obvious first, right? Seems to be transmitting a fair amount of heat to the case as it is.

    I've only had to replace them on a CF-29 and very effectively used Fujipoly Extreme 1.5mm pads. Shouldn't be long before someone else can tell you if that would do for a CF-30 or not.

    I've just torn my CF-30 open to do the same. Measuring the thermal pad mine was 2mm thick, the one in the video looks as thick also. I was going to order Arctic thermal pads from Amazon but decided to try the 2.0mm (CPU to Heat pipe block) & 0.5mm (Heat pipe to bottom cover) Panasonic EYG-T Graphite-PAD's instead from Digi-Key (Double heat transfer ability). Can't find much about people using them but I see that they are conductive instead of the typical non conductive style thermal pads. Wouldn't that possibly be detrimental to electrical/static protection? Using a Panasonic product to fix a Panasonic product is nice to say.

    That's it. It's next day shipping so I'll post how it works by tomorrow with a few photos.
