COMPAQ - model #CQ60-307EA is the model in question
The minor, blue covered central lead , i think, was turned back within the
fill of the connector shroud, not connected to the pin, safer leaving
disconnected without any specific knowledge.
Just leaving the polarity of the 2 concentric cylinders taking the 4.74
amp
rating
Just looked at another known Compaq (Compaq Presario 2700EA) and DVM
testing
the simple 2 way DC power connection , nothing on diode range.
no reading on R range one way
but other -2.8M on 30M range , DVM+ to known neagative and chassis ground
-260K on 3M range
and with another DVM
-6M on 20M range
-600K on 2M
-25K on 200K
how universal is that ? if not able to power up with current limited bench
power supply, monitoring voltage.
not found a www ref specifically to that Compaq DC polarity.
Did just DVM the blue lead back to the mains connector and 1.3M regular
resistance back to mains ground pin, nothing showing on any other routes.
