I purchased a MacBook Pro 15 inch mid-2010 (2,4 GHz Intel Core i5, 4 Go 1067 MHz DDR3) soon after its release. I had a few battery-related problems a few months after I purchased it, so the Apple Store changed the entire motherboard under Apple Care. Fast forward to the present and now I have multiple problems with my Mac: USB ports and SD card slot don't work Bluetooth signal is very weak, bluetooth mice don't work Battery won't keep a charge and lasts about an hour I'm thinking it's the motherboard again. What do you suggest that I do? If I go to an Apple Store, will they change the motherboard again under Apple Care? It's a custom machine with a high resolution matte screen. Would they offer to switch the computer with a brand new one? I'm looking to sell this computer, but I know I can't sell it in this sorry state. I live about 2 hours away from the nearest Apple Store, so I would like to know what to expect. Thanks for your help.
