Installing Memory, an Internal Storage Device, or a PCI
Expansion Card, or Replacing the Battery
These instructions describe how to install memory, an internal storage device, a PCI
expansion card, or a replacement battery.
Opening the Computer
1 Shut down your computer by choosing Shut Down from the Special menu. Then wait 5
minutes to allow the computer’s internal components to cool.
2 If you attached a security cable through the computer’s lockable cover latch, remove the
cable.
3 Unplug all the cables from the computer except the power cord.
Warning The power supply in your computer is a high-voltage component and should
not be opened for any reason, even when the computer is off. If the power supply needs
service, contact your Apple-authorized dealer or service provider.
Warning Always shut down the computer before opening it to avoid damaging its
internal components.
Important Before installing any of these items, carefully read “About Memory,” “About
Internal Storage Options,” “About PCI Expansion Cards,” and “About the Computer’s
Battery,” earlier in this chapter.
Warning Turn off the computer properly before you open it or you could lose data.
