OOT:Power Quality in Data Center

the scenario

you arrived in data center,
you plug your laptop adaptor into rack PDU,
your touch-pad pointer going crazy.
so you grab a usb-mouse & connect it to your laptop.

then your cisco switch doesn't function properly,
it was ok when you configure it in the office.

have you ever encounter this issue ?

some people told me it was harmonic problem
some said it was grounding problem
any idea ?
is there any tools to measure the power quality
before the customer ask me to replace the whole rack and switches
