My old power supply died. I purchased the correct, new power supply as prescribed by Apple. The first time I plugged it in, it didn't immediately start charging. I adjusted the connector and managed to get one full charge. The next day, I plugged it back in and I haven't been able to get a charge since. It's like the connectors aren't connecting. I've read about this being a bit of a problem for some people but I can't find any solution. I also can't find an old "t" style MagSafe adapter. So, does anybody have a fix or know of a place I can purchase an older adapter? I've been wanting to sell my old MBP (replaced with new i7 iMac. woo hoo!) but I can't do that until I've wiped it and have the power! Thanks for the help.
