Battery gauge:
The battery gauge consists of five LEDs, which indicate the
approximate charge remaining on your computer. When all five
lights are lit, the battery is fully charged. As you use the battery,
the lights will turn off from top to bottom, indicating the amount of
charge that remains. Each light represents approximately 20%
of the full charge. See
Chapter 2 “Batteries and Charging
Procedures” for more detailed information on the battery gauge.
Charging status LED:
The charge status indicator is lit whenever external power is
available. It blinks as the battery charges and remains a
constant green when the batteries are fully charged. The
indicator identifies a positive connection when the
HAMMERHEAD RT is in the docking station with an external
power source. The indicator will be green when external power
is connected.
Hard disk drive indicator:
The indicator flashes as the internal hard disk drive is accessed.
Backlight control sensor:
The backlight control sensor automatically turns the backlight off
when adequate external light is available. Make sure you keep
this sensor uncovered.

USB connector:
The Universal Serial Bus is a hot swappable, daisy chainable
serial port. It can be used for devices like keyboards, mice,
floppy drives, CD-ROM or DVD drives,
cameras, modems, scanners, etc. Devices can
be connected to the HAMMERHEAD RT with
the computer turned on, without requiring a
reboot. There is a limit of 128 concurrent
devices per USB port. The HAMMERHEAD RT
can supply up to .5 amps of current through the USB port.
External USB hubs are available that will supply power to
external devices without using the HAMMERHEAD RT’s power
supply.

CardBus/PCMCIA expansion slot:
The CardBus/PCMCIA expansion slot
is sealed behind a door held in place
by two Phillips head screws. The
door must be removed to access the
slot. Several doors are available that
will accommodate various
CardBus/PCMCIA devices with
features that extend beyond the
housing of the computer. These
doors keep the unit as sealed as
possible.
External power connector:
This connector allows the user to plug the AC power supply
directly into the HAMMERHEAD RT to charge and operate the
unit. The unit may also be charged through a port replicator or
docking station.
Do not connect to more than one power
source at a time when charging the unit or permanent
damage may occur.
Ethernet RJ45 Connector:
Built-in Ethernet is standard on both HAMMERHEAD RT Tablet
PCs. The RJ45 jack allows the user to connect their
HAMMERHEAD RT computer to their network via a standard
Ethernet cable.
