I have a mid-2009 MacBook Pro, Core2Duo 2.26GHz, nVidia 8400M vídeo, 8 GB RAM, fusion drive (120GB SSD 750GB HDD). All working fairly normally, considering its age. Recently I bought a new 60W power supply. Though it was apparently working OK for the first few days, earlier today the power supply would not charge anymore. No LED signal, no LED lit up and no charging indication on the menu bar. Since the battery is now over, I tried to measure the voltages directly on the board. I wired up my MagSafe adapter and connected the VCC lines to de VCC lines and the GND lines to the GND lines of the DC in board, thus bypassing the MagSafe connector. When I measure the voltage entering the the DC In board, I get 16.26V as expected. However, I can't turn on the machine, it behaves like there's no battery charge at all. No white screen on boot, no startup chimex nothing. It simply doesn't turn on. Tried doing it via the power button and the power pads, but nothing works. Do you guys have any suggestions about what can be happening here? I can't figure out if this is a supply problem or if it is some problem with the MacBook itself. I also can't take it to a Genius Bar because there is not a single genus bar service (or any Apple Store) here.
