swapped PSU with new one. computer works fine. returned to 
magen.

Received replacement part.  Please bring me old PSU 
as I have to ship it back to Dell.  I will give you 
new PSU to replace and get machine back.

Task reassigned to Lori Burgeson.

today megan gave a computer for me to trouble shoot. saying 
the at the computer wouldn't power up i took the following steps

plugged in computer as normal: the computer had a blinking 
amber power button light. also had enough power to run the 
fans but nothing else.

switched the power cable: same things happened.

was unable to get power to the machine with nothing plugged in 
besides the power cord(thinking there was power but the other 
I/O devices were taking the power) same result as before.

swapped PSU from working computer of the same model: this 
switch worked and the computer was fully functional.
