Removing a disc with the computer off
1 Insert a slender object, such as a straightened paper clip, into the
manual eject button access hole.
Never use a pencil to press the manual eject button. Pencil lead can break off
inside the computer and damage it.
2 Pull the tray fully open, remove the disc and place it in its protective
cover.
3 Close the disc tray by pressing gently on the center of the tray until it
clicks, indicating that it is locked.
Moving the computer
Before moving your computer, even across the room, make sure all disk
activity has ended (the disk activity light stop glowing) and all external
peripheral cables are disconnected.
Never pick up the computer by its display panel or by the back (where the
ports are located).
Mobile computing
Running the computer on battery power
The computer contains a removable lithium ion (Li-ion) high-capacity
battery that provides power when you are away from an AC outlet. You can
recharge it many times.
To ensure that the battery maintains its maximum capacity, operate the
computer on battery power at least once a month until the battery is fully
discharged. Please see “Maximizing battery life” on page 49 for
procedures. If the computer is continuously operated on AC power, either
through an AC adapter or a docking station for an extended period (more
than a month), the battery may fail to retain a charge. It may not function
efficiently over the expected life of the battery and the battery light may not
indicate a low-battery condition.
Charging the RTC battery
Your computer has an internal real-time clock (RTC) battery. The RTC
battery powers the System Time Clock and BIOS memory used to store
your computer’s configuration settings. When fully charged it maintains
this information for up to a month when the computer is powered off.
