They can connect via USB so you can do things like perform a clean shutdown when it loses power

Don’t forget rs232 and Ethernet! 😁

I’m picking a brand for a service offering HaaS. And am hoping I can find a brand that has central management.

Yep even mid range ones did so way back in the early 90s. It was a common fairly cheap feature that used rs232 mostly. In those days non unix systems did not care as much if powered down without warning. So us early (me 1996) Linux users really found it useful to have the ups initiate shutdown before it died. Windows users of the time only tended to worry if they had the PC running when not sat their. Few had internet at home in the early 90s and those that did were dil up. So for many it was not worth the cost when you could just turn off the PC if a power cut was long term.

Now with most people using laptops for casual use. I really cant imagin anyone buying one without the feature.

If the computer gets notified that the battery has been activated, then it can save files, gracefully exit programs, etc. before power loss

It’s possible for them to tell the computer to shutdown when the battery is getting low

My understanding is that more advanced ones will tell the computer when they’ve been switched to battery power and how long they can expect it to last. In the worst case, the system can save to disk and shut down right before the UPS is about to cut it off.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
