ThinkPad keeps turning off because temprature is too high when charging

Thinkpad (Lenovo ThinkPad X1 Carbon Gen 9) Overheating resolved

This laptop overheats a lot, which makes it turn off a lot. As soon as I connect it to the charger, and it's in balanced power mode, the CPU temp goes over 100.

This is an adaptation of https://kobusvs.co.za/blog/power-profile-switching/

Solutions

1. Based on charging (battery-goes-brrrrrrrrrrrr.sh)

Charger increases battery temp a lot, combined with doing something heavy it skyrockets the CPU temp over 85 easily, meaning as soon as it is over 90 there is a 90% chance it will turn off soon.

This script switches the laptop into power-saving mode as soon as the charger is connected.

2. Based on CPU temperature (temp-goes-brrrrrrrrrrrr.sh)

This script takes CPU temperature into account, meaning as soon as the CPU is constantly (for 10s) over 75 degrees, it will switch into power mode and check again in 5 minutes if it can go into balanced mode again.

3. Based on CPU temperature (Simplified) (simple-temp-goes-brrrrrrrrrrrr.sh)

This script takes CPU temperature into account, meaning as soon as the CPU is over 80 degrees, it will switch into power mode and check again in 5 minutes if it can go into balanced mode again.
