testing compaq power supply ?
 

I inherited a compaq presario that had just gone dead, no fan on power
supply
no boot up, nothing. I installed a new power supply from compaq and
still nothing. I just read there is a turn on terminal for some power
supplies,
either this thing is not being turned on or I received a defective
power supply from compaq ? How do I test this power supply out of the
'puter ?

Then again it could be the mobo ?? (not giving "power good" etc).
To test the PSU if a standard ATX, you usually have to take the green pin #
14 to gnd and put a load on the 5v line (about 0.5 amp).
If the compaq is a proprietry thing you might find help on
www.hardwarebook.net/connector/ have a look in any case it's a handy source
of info.

HeHeHeHE.... :) Reset the CMOS (there is proabbly a jumper and see if
it helps. These PCs will play dead if the CMOS is corrupted, even to
the point of no power at all.
