I've just completed work on the IBM T43. It seems that the connector problem that Dell, HP, Compaq and Toshiba is not a problem for this laptop. This unit atteches the AC adapter connector to a stiffener with a screw, not the main board and attaches to the main board by wires and a connector. This does not allow damage to the connector to be transfered to the mother board. Thats the good news. The bad news, They may be cutting into laptop repair profits.:)

Something I've done with every laptop I've bought.

Make an power adapter dongle so that if the original power cord is pulled it will separate from the dongle rather than over-stressing the laptop connector

This saves the laptop connector from being damaged and can keep a laptop from being accidently pulled to the floor.

It's cheap, and it can be done with almost any laptop, and it doesn't affect warranty because neither the laptop nor the power brick/cord/jack is altered.

One end of the dongle is a plug that fits the laptop power input jack. The other end is a jack that fits the original laptop power output plug. It's not much more than a male-female patch cord.

This method applies mostly to "coaxial" power plug and jack connector systems. I haven't tried it for any other laptop connector types.

I've made 2 basic versions. One is a very short dongle, about 4cm long cord. The other is about 50cm long cord.

The shorter dongle simply provide a 'path of least resistance' point to separate. By being flexible, it helps keep the power cord plug and dongle jack lined-up with each other, so that they separate more easiliy. It can help if you adjust the dongle jack so that the power cord plug isn't held too tightly, but the risk there is that it won't be held tightly enough. You have to experiment with that.

The longer dongle can be used 2 ways.

It can be situated so that most of the dongle cord lies under the laptop or a heavy book. This

1) provides some slack in the cable that compensates for minor accidental pulling on the power cord or brick.
2) provides enough added resistance such that the power cord always separates from the dongle jack before the dongle separates from the laptop.

The second way is to provide a means to attach the dongle cord securely to my desk. That guarantees that the dongle will take all of the stress if the power cord is pulled away (by tripping over the cord, etc) At times I've used a simple knot, cable ties,etc to secure the dongle cord to my desk.

(note: dongle cable must handle current that laptop requires. An inline fuse can be used if desired.)

edit to try to get the <-- in bold as well...the markup lianguage interpreter doesn't like the < character, I think
