Oh no, I think my latopt battery has decided to give up ðŸ˜ðŸ˜ðŸ˜
At least the laptop itself seems okay still.

Before you replace the battery consider buying a used thinkpad. Often cheaper as a battery and very robust. Some are even upgradable. If you only do normal office stuff i can recommend the thinkpad x230 (small) or t430.
