Has anyone attempted to repair the external power adapter port on the PMU in a powerbook 5300? After having read about all the joys that can happen to the unit, the small plastic block that the AC adapter plugs into is clearly cracked. It is not exactly the easiest thing to get at, either. I'd like to avoid spending $40-60 on a replacement PMU for a system that was $5 at a garage sale - but still fully functional - good battery, got a pcmcia ethernet card for it, lots of scsi peripherials to use with it... just can't keep it charged due to the plug being cracked. I think every time I manage to get an electrical connection, it is at the expense of breaking the block more.
If anyone has any ideas, suggestions, or actual experience trying to fix this, I'd really appreciate it. I'm not convined that an epoxy job on the outside of the block is going to do the job, but maybe that would suffice?
