I totally feel you on this. In my case I got into homelab after also getting into 3d printing, a hobby that really could be a fire hazard if something went awry, and my brain has wrongly filed my new hobby under “all hobby things that run continuously are a fire hazard”, even though in reality the risk here is basically zero. It probably doesn’t help that when I got my first 1u server I only plugged in one of the redundant power supplies and the other popped and let out the magic smoke.
Maybe go ahead and take out the battery for now. If you want to keep it in as a built in ups(one of the main benefits of using a laptop), one route is to run Home Assistant and put the laptop power cord on a smart plug. Figure out how to get the laptop battery % into Home Assistant and turn the plug on if the laptop goes below about 35% and back off when it goes above 85%. This is the strategy used by many people to prevent spicy pillows in wall mounted tablets, but same idea would apply here.
