 Preparing to Work Inside the Computer

Before you start to work on the computer, perform the following steps.

NOTICE: Failure to perform the following steps could result in damage to the computer.

NOTICE: If working inside your computer involves the removal of the palmrest, note this information about the reserve battery. The
reserve battery provides power to the computer

’s real-time clock (RTC) and nonvolatile random-access memory (NVRAM) when the

computer is turned off. Removing the palmrest disconnects the reserve battery and causes the computer to lose the date and time
information as well as all user-specified parameters in NVRAM. If possible, make a copy of this information before you disconnect the
reserve battery.

1. Save any work in progress and close all open application programs.

2. Turn off the computer and any attached peripherals.

3. If the computer is docked in an advanced port replicator (APR), undock the computer.

4. Disconnect the computer and any attached peripherals from their electrical outlets to reduce the potential for personal injury or shock. Also

disconnect any telephone or telecommunications lines from the computer.

5. Remove the power cable.

6. Disconnect all other external cables from the computer.

7. Remove any installed PC Cards.

NOTICE: Make sure that the work surface is clean to prevent scratching the computer cover.

NOTICE: To avoid damaging the system board, remove the power cable, the battery, and the second battery (if installed) before you
service the computer.

8. Remove the main battery assembly from the battery bay.


Slide the battery bay latch toward the unlock icon. Then slide the battery out of the battery bay (see

Figure 2

).
