If you mean that the computer power should have been UNPLUGGED from
the wall, this is NOT a good idea when installing chips.  Unless you
are working on the power supply itself, you should NOT install chips
into an unplugged computer.  The computer should be TURNED OFF, but
NOT unplugged!  The power plug/cord is what grounds the computer.
When the computer is not grounded, one is just further increasing the
possibility of static discharges ruining the chips being installed.
The computer should be plugged in, turned off, and the wrist grounding
strap connected to the computer's power supply chassis (grounded).  An
anti-static mat should be used to hold componentry not in the
computer.

A good thing for your customers -- one of these days installing chips
into an unplugged computer might cost you a few cents...
