Toshiba 1750 Broken DC Input Power Connector

[Don Christine]

Hello,

I accidentally dropped my Toshiba Satellite 1750 notebook PC on its rear
with the external power supply plugged into it. It landed directly on the
power supply plug, and broke off the DC input connector on the inside.

I have disassembled the entire the PC and removed the mainboard, and found
that the internal connector was soldered onto the mainboard. Two solder
lugs held it in place on the system board. I unsoldered the connector and
soldered two 24" long wires to the board, and reassembled. Everything came
back
fine, but when I tried connecting the wires to the DIN plug from the
external
power supply, the power supply shut down as in a direct short. Switching
the
wires on the plug (reversing polarity) resulted in the same thing. Makes me
think that
the connector was a more than just a connector...but I don't know.

Does anyone know how I might be able to go about identifying the part number
for this connector? Are schematics available for the system board that
might
help to identify it? I really don't want to have to spend $200 for a new
system
board if I don't have to.

Thanks in advance,

Don Christine

Considering that you mentioned that you soldered on a pair of wires to bring
out of the laptop to the power supply unit, did you make sure that you are
on the correct traces?

If you were on the correct traces, but accidentally connected the power
supply to the computer in reverse polarity, it is very much for sure that
there are damaged parts on the mother board.

In the way of safety for the computer, and for yourself, the connector
should have been replaced with the proper one.

Considering that you wanted to try to save a few dollars to have the machine
properly fixed, you may now have a blown mother board. This is going to be
costly, if this is correct.

One thing I can tell you from experience from working in a lot of places, if
there are laptops, they will all be dropped one day or another!
