Somewhat chewed up, seems to be 7.3mm outside diameter, 9.5mm deep, 5mm
inside diameter , about 0.5mm pin but tip recessed 5mm into body, would it
be recessed by as much as 5mm ?

I'll try some calculations on the foreshortened image on there but not far
off 5mm recessed just going visually.
I wonder if they do a splicing kit, to avoid trying to break into the box.
Some sort of 5 amp compact connector and a 2 part black rubber formulation
and 2-part mould that fits around the cable.

The most chewed up area is the cover. 3 connections at the active end, pin
and inner and outer rings not connected at the plug. Two leads coming from
the supply but are the 2 rings connected to one supply line or just one and
which one ?

HP Laptop power supply output plug
 

The remnants of the connector had a black covered wire and a blue covered
wire going to the cylinder parts of the connector. I don't suppose there is
a standard for these sorts of things , but it looks as though the blue one
was not connected through to the power supply so just one lead but connected
to the inside or the outside cylinder of the connection. This is a pin
centre conductor , not a female connector.
My guess is the inner surface as then both conductor surfaces are recessed
from casual touching anything when disconnected.

from the aptopjacks pic then recessed very approx 0.38 the length of the
exposed barrel in the skew-on view, which makes it 5.1mm recessed going by
the straight on view, so I'll take that as pin tip recessed 5mm

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.

I assume the small diameter core wire and central connector pin are for
static discharge to ground, when used, not in this particular case

Some of these supplies use I2C communications to 'tell the computer about
the power supply capabilities'. Without the I2C communications, the
computer may complain that the supply doesn't have sufficient capacity to

I think that the computer senses when a voltage is present on the power
jack. I think it then asks the supply 'who are you'. If the supply says 'I
am an 85 (or whatever) supply', the computer is happy. If it doesn't reply
or says 'I am a low wattage supply', the computer gives an error message.

I base this on the fact that the error message appears when I plug in my
'broken' power supply to the computer OR when I plug the supply into the
AC, but not when I plug in a 'good supply' although the 'AC/battery
indicator' changes when either supply is connected.

it's probably just a resistor value that gets read,forms a voltage divider
and the developed V gets read. Simple,cheap to implement.
No resistor,you get the "insufficient supply" message.

"AC power adapter type cannot be determined"

When I startup my computer, I get the message “The AC power adapter type
cannot be determined. Your system will operate slower and the battery will
not charge."

This error occurs due to a communication error between an id-chip within
the AC adapter and the laptop. Mostly the issue is due to unprotected
1-wire id-chip getting destroyed, or the laptop motherboard being damaged.
This issue has been known for a long time and DELL has done nothing to fix
it or compensate customers more than replacing the damaged component
within warranty, i.e. AC adapter or laptop motherboard. There are reports
of customers replacing the AC adapter several times. This indicates that
it is a design flaw, wrong construction that can destroy the id-chip. More

well,then you buy some "ID chips",and make an adapter that carries one,and
your generic power supply plugs into that adapter.the adapter stays with
the PC when you unplug the PS,so the ID chip doesn't get destroyed or
damaged.
Perhaps you could even wire the ID chip directly to the PC motherboard.
Maybe it just needs a MOV or spike protector across the input.


the "ID chip" design smells(stinks,actually) of deliberate action to
preclude use of inexpensive aftermarket supplies.

HOW does a "one-wire ID chip" work,anyways?

Heh,"one-wire ID chip" sounds like a chip resistor.
