RAM Expansion
The PowerBook (FireWire) has two RAM slots on the microprocessor
board, and no RAM soldered on the I/O logic board. All units ship with a
minimum of 64 MB of factory-installed RAM. The maximum amount of
RAM supported is 512 MB. The PowerBook (FireWire) uses standard
144-pin SDRAM SO-DIMMs with a height of up to two inches.
RAM Compatibility
SDRAM SO-DIMMs used for PowerBook (FireWire) must be PC-100
compatible. Previous PowerBook G3 Series computers used PC-66 RAM
that may not be compatible with this computer.
As with the PowerBook G3 Series computers, EDO RAM should not be used.
Battery Compatibility
The Lithium Ion (LiIon) batteries used for the PowerBook FireWire) are
compatible with those used in the PowerBook G3 Series (Bronze
Keyboard) and vice versa. Batteries from earlier PowerBook G3 Series
computers are not compatible with PowerBook (FireWire).
Battery Level Indicators
LiIon batteries have battery level indicator lights that tell whether the
battery is fully charged, three-fourths charged, one-half charged, one-
fourth charged, or empty. To check the battery charge, press the status
button located next to the status lights. The battery charges whenever the
external AC adapter is connected.
If the battery lights blink, there is a problem with the battery. If only one
light blinks, the battery is fully depleted and needs to be recharged.
