Main Logic Board

The hallmark of the MacBook Pro (17-inch) and MacBook Pro (17-inch Core 2 Duo) is the Intel Core Duo and Core 2 Duo chip, respectively, each with a ATI Mobility Radeon x1600 graphics chip. The microprocessor is soldered to the main logic board. It is not upgradable.

All ports in both MacBook Pro 17-inch models remain the same. The port differences between the MacBook Pro and the PowerBook G4 include: the MagSafe power port and second USB port on the left, as well as ExpressCard/34 replacing what was previously a PCMCIA card slot. The security lock slot is on the right side of the system. Due to all the port re-arrangements, the new logic boards will not fit in any Macintosh 17-inch PowerBook G4s or vice versa. Composite and S-video connections are now only available using an optional Apple DVI to Video adapter.

The boot architecture of the MacBook Pro is based on Extensible Firmware Interface (EFI), replacing Open Firmware (OF) of PowerBook G4 days. Boot snag keys such as "C" for boot from the optical drive, "N" for network boot, and "T" for Target Disk Mode stay the same under EFI. To launch Apple Hardware Test (AHT) from the Mac OS X Install disc, you must hold down the "D" key during boot.

Unlike the MacBook Pro (17-inch), the MacBook Pro (17-inch Core 2 Duo) now utilizes JST wire bundle connectors that disengage by lifting up and pulling the connector out of its mating part on the logic board. To reconnect, just snap the connector back in, making sure it is seated securely. The fans, thermal sensors, and backup battery all use this connector.
