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 dail 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.
