17 | Can't say that I have. But what you describe is a failing Standby
18 | voltage circuit. It could be the power supply or it could be the
19 | motherboard.

21 | If either has significant age on them, then most likely to electrolytic

23 | simply be bad design and no real testing of the function during
24 | production.
