Charging MacBook with power cable
My power supply stopped charging. I noticed the wire broke from the transformer, I.e. the 16V DC. So i cut it and resoldered it.
However like a complete imbecile I switched the wires, i.e. + to -, and vice versa. I coonnected it to the mac, and no charging light was showing. It was only then on reinspection I noticed the error and rewired correctly.
It seems that the transformer has voltage, but on connection to the mac there is no charge light.
The computer works, albeit rapidly about to have no battery charge, but ...
?Have I damaged the charging circuit somehow?
Is this a good question?
