I have had a Dell Latitude-5501 (with Linux Mint 19.3 MATE) laptop for about a year. A day or two ago it stopped charging over 79% plus the battery drains pretty quickly.
I do not remember installing anything special and of course, I did not change the computer hardware.
I tried to charge the battery even when the computer was off. Charging in different sockets in the house or disconnecting and reconnecting the charger also doesn't help.
