 While this was happening, I carefully watched the temperature sensors:


 CPU remained static at 40 deg C

Temp1 remained static at 40 deg C

Core 0 started at 35 deg C and slowly rose to 90 deg C at which point I
quickly copied & pasted the terminal output, and hit RESTART, by which time
the temperature had risen to 94 deg C.


 When my laptop automatically switched on again, about a minute later, the
CPU and Temp1 sensors, which had been stuck on 40 deg C, both indicated 85
deg C, as did the Core 0 sensor. However, the cooling fan is now working,
and all three temperature gauges have dropped quickly to 55/55/48 in the
time it's taken me to type this paragraph.

Does any of this help?

I really appreciate your help with this problem.

Thanks & regards,

Tony
