Lightning - charger connection

[Howard W. Knoebel]

Lightning struck.  My titanium power book G4 was not plugged in and it 
worked after the strike.  The power supply was plugged into the wall but 
not to the computer.  When the Tibook battery ran down, I reconnected the 
power supply but did not notice the light in the connector.  Later on I 
noticed the Tibook was dead.  The battery showed no charge.  Upon close 
examination I found some burn damage near the light on the 
connector.  Thinking the power-supply was ruined by the lightning, I 
ordered a new one.

I connected the new power-supply to the now dead Tibook and the green light 
in the connector came on.  There was no yellow.  The computer remained dead.

I wonder if the damaged power-supply could have caused trouble in the 
Tibook.  Does the computer battery connect to the power-supply port?  Could 
back flow of current cause damage to the computer?  Are the rectifier 
diodes located in the power-book thus giving protection against back-flow 
or are they in the power-supply in which case back flow would be likely?

Would repair be feasible?
