How do I prove poor AC input?
Posted on 2006-11-21
Hi, I see this power problem from time to time but would like an explanation for my customer:
The PC will not start up or will cycle itself off and on intermittently or even reboot unexpectedly.
But when it is moved directly to a different wall outlet on a different AC circuit and/or removed from
the surge bar and plugged directly into the wall, the problems go away.
This can happen even after replacing the power supply with a "high-end" good one. So, what is it about
the AC input side of the power that can cause the problem? How do I test and PROVE it's a problem
with the customers' wiring or utility?
