My main travel laptop is still an old Thinkpad X220, because of the great keyboard.
It lasts considerably longer on Ubuntu 20.04 than in Windows 10 $LATEST. In Windows, it runs too hot to have on my lap, and the fans run constantly.
In Ubuntu, it runs cool and I rarely hear the fan at all.
Check your firmware is current: that's step 1.
