Do any of you have suggestions about solving this mystery ?
If google allows it, try
grep '' /sys/class/power_supply/*/*
to see some numbers related to the battery an perhaps to the AC power
supply. Otherwise boot a Linux live image (e.g. from USB) and try the
same command and a one that may present battery state in a more readable
form:
upower --dump
The charger is fine when used in another laptop.
Another laptop may be power hungry in less degree. It is better to try
another power supply with this laptop in addition.
My experience is that if AC adapter is put into a bag twice a day then
it has to be replaced or repaired after a couple of years due to cable
wearing. Additional resistance of about ~1 Ohm due to broken wires at a
bending point is enough to cause issues under some CPU load. In my case
first symptom was some noise on an external monitor connected by a VGA
cable, so I suspected a more severe problem.
