Morphology
The base verb 'act' (to behave) makes the human-behaviour sense partly derivable, but the particle 'up' does not literally mean 'badly' or 'malfunction' and its contribution is idiomatic and variable. Because the combination suggests abnormal or problematic behaviour/malfunction but requires familiarity with phrasal-verb patterns to predict both human and mechanical senses, the expression is only partially predictable to a B1 learner.
Etymology
Act up can also mean to misbehave or stop working properly. Think of act (behave) plus up (more extreme) — a child, a dog, or a machine that suddenly 'acts' in a noisy or wrong way and causes trouble. So act up means 'to behave badly' or 'not work properly'.
