Hello Henrik'
I too would suspect an ethernet software/driver problem, followed by 
overheating. As far as I know all default to the simplest and slowest mode, 
then negotiate the optimum working conditions.
While I was searching for a graphics fault on an IBM/Lenovo laptop I noticed 
that dmesg was almost entirely full of ethernet errors, but I think I may also 
have a real hardware fault because even new and old live DVD versions of 
knoppix and ubuntu have stopped booting.
I have just looked at a Lenovo laptop which has an Intel e1000 ethernet, that 
is working OK but both the knoppix 7.7.1 DVD and debian stretch versions of 
dmesg have complaints about the internal APIC driver, asking if there is a 
better one available.
