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?  Can you get a schematic 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

The power connector on the 1750's that I've seen and repaired is just a 
standard 2-wire coaxial jack -- it's not a "din" connector.  In fact, 
until about a year ago, while they used a couple of different sizes, 
Toshiba had never used DIN connectors for power.
