My Macbook won't charge at all. I have two power cords (original and one that came with a friends Macbook Pro purchased earlier this year) -- both experience the same issue: When charger is plugged in, the green light turns on (on the charger) but the battery doesn't charge. I can use the computer fine while the computer is connected to the charger, it's just when I remove the charger, the computer shuts off. My battery says it is at 0% and I have done the following things: - Applied the MacBook SMC Firmware Update 1.4 (when I went to install it said I do not need this update). - Reset the SMC. - Shut down the mac in every which way. - Reset the mac. - Took out the battery - Made sure there is nothing interfering or dirty on the magsafe connector Specs: Model Name: MacBook Model Identifier: MacBook3,1 Processor Name: Intel Core 2 Duo Processor Speed: 2 GHz Version OSX 10.5.8 Any ideas?
