it only works as a UPS if you periodically discharge the battery. My first “server” was a compaq laptop, I had used it for years and then reprovisioned it to Ubuntu Server, after 2 or 3 years of 24/7 if you unplugged it at all it just instant died because keeping it 100% charged all the time killed the battery.
Naively I assumed that anything in the last decade or so with a battery already has some sort of battery management system that regulates this stuff to help prolong battery lifespan, but maybe I’m wrong.
Yea, which is a fair expectation, but it’s not a safe assumption. Verify it does before prolonged use. Make sure its well ventilated(heat is killer to batteries as well), and that some form of BMS is present on the system, and that it’s enabled because some have the system but have it disabled by default.
