Track down a number of hardware problems using the MacBook troubleshooting guide.


You can cost-effectively upgrade a number of components in the MacBook Core 2 Duo.

  • Memory: The MacBook Core 2 Duo shipped with 512 MB or 1 GB of RAM. If your MacBook is still running with only the stock RAM, upgrading will provide a dramatic performance boost at minimal cost. Upgrading to the maximum (3 GB for Core 2 Duo, 4 GB for Santa Rosa or Penryn) can be done very easily.
  • Hard Drive: 60, 80, or 120 GB hard drives came standard with the MacBook Core 2 Duo. You can upgrade the drive up to 750 GB.
  • Battery: Replacing the battery requires a coin or a flat-edge tool release the battery latch. The battery can be replaced in less than 30 seconds.
  • Optical Drive: The standard optical drive shipped with MacBooks is either a Combo Drive or a 4x, 6x, or 8x SuperDrive. The optical drive can easily be upgraded to an 8x SuperDrive.

Identification and Background

You can verify that you have a Core 2 Duo MacBook by checking the processor information through "About This Mac" in the Apple menu. If your computer's case is plastic and "About This Mac" says you have a Core 2 Duo, then you're in the right place. If your computer has a metal case, you could have the MacBook Unibody or MacBook Air.

Use the laptop identification system to help you identify your machine. MacBooks tend to look very similar, and it's important to know which machine you have before ordering any replacement parts.

This laptop was an update to the MacBook Core Duo Repair that was introduced six months earlier. It came in two colors: basic white, and optional (and more expensive) black. The same industrial design employed by the MacBook Core Duo was also applied to the Core 2 Duo, as the overall size, shape, and layout of the laptop did not change. As with the original MacBook, this laptop included an iSight camera and used the same MagSafe power connector.

The primary improvements that Apple made in the MacBook Core 2 Duo were the addition of a faster processor, improved AirPort, and a larger RAM maximum capacity.
