Comment on Selfhosting on old MSI laptop

Never had this happen, and I’ve carried laptops since the mid 90’s, and they’ve always been plugged in most of the time.

Get to office, plug on, get home, plug in and sit overnight in the charger with no use.

I’ve seen a few expanded batteries, but that’s across the hundreds of laptops in my support circle. It’s very rare.

Every laptop I’ve had in the last 5 years has battery protection built in anyway. I’m running 2 laptops from 2019 that have it.

Though you do make a good point, something to figure out if your laptop does this. And to keep an eye on the batteries anyway (like check battery health quarterly), and replace if it gets down significantly (I replace mine at 70% health).

My personal experience with laptop batteries was not as nice as yours, but neither should be blindly trusted.

Not sure if there is some science on it anywhere but this random search result article pcmag.com/…/help-my-laptop-battery-is-swollen-now… says:

most common cause of a swollen battery is overcharging. Keeping your battery at a high state of charge can stress it out, allowing it to degrade faster. “In an application where you have a system plugged in 24/7, after a number of years your likelihood of getting a swollen battery increases,” says Phil Jakes, principal engineer and director of strategic technology at Lenovo. “The other thing that drives it is heat. Batteries don’t like to be hot, and there’s a chemical process that gets kicked off when a battery gets over 100 degrees.”

So I guess best is to set charge limit and make sure the “server” doesn’t get hot.
