interesting.
so the synopsis is: Just replace
the motherboard battery?

Well it is a bit more complicated than that. The simplest oscillator is
a cap and a coil in parallel. Give it a quick zap and it will oscillate
at a frequency determined by the values of capacitamce vs. inductance.
The oscillations will stop from loses without being refreshed by more
timed zaps.
Piezoelectric is like this (found in digital clocks), but it is like a
cyrstal rock between two metal plates. Smack it with a hammer (like in
those electric cigarette lighters), they will kick back with a voltage
(spark). Although kick it with a quick voltage spike and they vibrate.
And this vibating (oscillations) causes voltage oscillations as well.
And the lower the voltage, the weaker but faster oscillations they
produce. Thus cystal control clocks runs faster as the battery gets
weaker. Well until they get so weak that they can't cause it to vibrate
anymore.
