As for time - computer maintains time of day in a circuit
completely unrelated to standby power. That design dates back
to the first IBM AT that had no standby option. Again, first
learn circuits before posting how they work.

But they did run on battery, which would need replaced (yes so do
modern PCs, but the battery is so supplement the standby supply,
should mains power fail, plus power more efficient memory technology
than the ATs had).

Plus they couldn't put themselves into standby mode like modern ATX
systems.
