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.
I’m not sure that all laptops support capping, and I’m not sure if Panasonic ToughBook supports the drivers necessary to cap. I guess you could deploy TLP and check sudo tlp-stat -b
it’s not a toughbook and idk how to configure it but my letsnote cf-rz6 came with the battery charge capped at 80%, maybe it can be configured with their windows tool (or the acpi call made by that tool). i already have linux on it so can’t check tho…

one should cap the battery at 70% or smth if keeping it connected 24/7
