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 Duo.

  • Memory: MacBook Core Duos come with 512 MB standard. If your MacBook is still running with only the stock RAM, upgrading will provide a dramatic performance boost. Upgrading to the maximum of 2 GB can be done very easily by installing two 1 GB RAM chips .
  • Hard Drive: 60 or 80 GB SATA hard drives came standard with the MacBook Core Duo. You can upgrade all the way up to a 750 GB hard drive.
  • 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 or 6x SuperDrive. The optical drive can easily be upgraded to an 8x SuperDrive.
  • AirPort: The MacBook Core Duo shipped with an 802.11g AirPort card, but the stock card can be replaced with an 802.11n AirPort card.

Background and Identification

The MacBook Core Duo is the only MacBook with an Intel Core Duo processor (later MacBooks use Core 2 Duo processors). If your MacBook turns on, you can verify that you have a Core Duo MacBook by checking the processor information through "About This Mac" in the Apple menu.

Use the [/info/ID-your-Mac|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.

Apple shipped the MacBook in two colors: basic white, and optional (and more expensive) black. Two other precedents were also set by the MacBook Core Duo: Apple included a new built-in iSight web camera, and the laptops included MagSafe power connectors.

The MacBook Core Duo was replaced six months later by the MacBook Core 2 Duo, which offered a better processor, improved AirPort, and a larger maximum RAM capacity.
