Laptop Power connector Kaput

[Bill]

Hi
My mate (?) has managed to break the power socket on
the side of his laptop (those circular things withe the pin in the
middle). The power Cube / connector is ok (+20v Cube).
The socket is directly soldered on the side of the motherboard.
I have taken the thing to bits ..carefully picked the bits of the socket
away..
soldered two wires on the two 'pins' left in the motherboard from the
socket and as a test connected them to the Cube plug (temporarily)
Yes the polarity is correct (Centre pin +ve)....The damm thing still
doesn't power on...not even spin up the CPU fan....
Thats as far as I can go with the laptop..everything is Soo tight space wise
its impossible to monitor anything..anybody any other suggestiions...Its put
me off laptops for starters !!!what a pain
regards

Barrel plug... Very common. Depending on the size and how it connects to
the mainboard, you might be able to pick up a spare. If not, I'd just solder
a pair of small wires to the mainboard and run it out to a cable version of
the jack. It will be ugly but it will work.

How did you test? When the plug broke it may have shorted something out and
blown a fuse, etc.

Sounds like it was more than just the plug broken. How did he break it? If
dropped, it could be anything. Solder in a pair of wires and hang them out
of the case and reassemble the unit. Be sure to mark the polarity. Once
assembled, try connecting to the power pack and start it up. If she don't
go, you could be in for lots of cost to repair.
