Agree with BeamT about the cap.
However, 80% wouldn't generally cause a circuit to fail. It's an indication that it might be on the way out or that it was stressed (possibly from being in backwards), but it wouldn't generally be the actual cause of anything not working.
On the other hand, 80%
and high ESR could cause something to fail if the ESR is high enough. You can imagine ESR as adding a resistor in the circuit across the capacitor, which will throw things off by creating voltage dividers and stuff.
Long story short, check ESR if you're troubleshooting. Capacitance is only telling you part of the story.
