Rear View
The rear panel of the Notebook Computer offers several ports for the electrical connection to
peripheral devices.
DC-in Socket
This socket is where the Notebook Computer’s universal AC/DC power adapter is
connected to the system. To disconnect the power adapter, pull the plug (not the
cord) directly back.
Serial Port
This is a high speed NS16C550 compatible port to connect an external mouse for
example.
Expansion Port
This port is used to connect the proprietary Docking Station. All of the features of
the Docking Station are available through the plug -in process offering the Notebook
Computer access to a desktop system.
RCA Jack
This is an RCA jack to connect a TV set for example.
You may need to select the video standard (NTSC/PAL) for video display.
External Monitor (CRT) Port
This port allows the connection of an external monitor to the system. It uses a 15pin connector and supports super-VGA, and Simultaneous display of LCD and
CRT.
MIDI/Game Port
This port is used to either connect any MIDI device such as a MIDI instrument or
keyboard, or connect an external standard joystick.
Parallel Port
This is a parallel port to connect a printer for example. It supports EPP (Enhanced
Parallel Port) and ECP (Extended Capabilities Port) modes, but required as well is
the use of the connected parallel device’s software driver.
External Keyboard or PS/2 Mouse Port
An external keyboard is able to be connected to the system via this port. So is an
external PS/2 mouse to the system as another pointing device choice.

angle.
Battery Latch
Sliding the battery latch upward will unload the battery pack.
PC Card Type II Slot
The PC Card slot will accommodate a Type II format for system expansion
capability.
2.5” Hard Disk Drive
The system’s 2.5” hard disk features a high capacity for data storage providing
high access time for excellent performance.
3.5” Floppy Disk Drive
This is the location of the Notebook Computer’s 3.5” high density 1.44MB floppy
diskette drive. You may press the button on its top-right side for diskette ejection.
Internal Battery Pack
The Notebook Computer’s internal rechargeable battery pack provides the system
with the power for long run time.

Power
Before using the Notebook Computer, you must supply it power. If this is the first time the
Notebook Computer is operated, you should use the AC power source since the internal battery
pack may have self -discharged during shipment.
AC Power
The Notebook Computer features a universal, auto-switching power adapter. This adapter is
suitable for use nearly anywhere.
1. Connect the AC power cord to the power adapter.
2. Plug the power adapter to the DC -in socket on the rear panel of the Notebook Computer.
3. Plug the AC power cord into a properly grounded outlet.
15
Internal Battery Power
The Notebook Computer is equipped with an internal, rechargeable battery pack which provides
continuous portable operation.
Proper care is required for optimum performance:
• Do not attempt to disassemble the battery under any circumstances.
• The battery may explode if exposed to fire or high temperatures.
•
Avoid short circuit the battery by the metal terminals (+, -).
16
Duracell Smart Battery at Retail
You may replace with Duracell Smart Battery, available at retail outlets around the world, to
accurate indicate a fuel gauge of the predicted available charge for the present state information.
Recharged by AC Power
The system’s battery pack will recharge whenever the system is plugged into the AC power
supply, regardless if the system is being operated or not. Hours may be needed to charge the
battery pack for long service life.
Some instructions should be carefully concerned before you charge the battery pack:
• Upon the very first use, or after a long period of storage, the system might indicate that
charging is complete after just a short time. Simply remove the battery to cool it off
and then repeat the charging procedure at least three times.
• It is recommended to fully discharge the battery before charging to keep memory
effect
from capacity loss.
17
Second Battery Power (Option)
The Second Battery comes designed, in addition to the system’s internal one, to prolong the
battery life for the unit’s portable use.
You may need to replace the floppy disk out of the 3.5” drive bay with the Second Battery pack
for longer power life.

Operation
Hardware Configuration
Disconnect all power supply both AC adapter and battery pack before work on any hardware
setting.
CPU
The system is upgradeable with a wide range of speed and voltages of the Intel Pentium
processors, providing user with a Zero-Insertion-Force (ZIF) socket to facilitate removal of the
Pentium processor and installation of an upgraded one.
ZIF Socket
1. Lever along with a slotted screwdriver on the ZIF socket’s OPEN position to unlock the
CPU.
2. Aligning the CPU’s index corner with the socket’s to install the CPU into place.
3. Lever along with a slotted screwdriver on the ZIF socket’s CLOSE position to lock the CPU.
Heat Sink & Fan for CPU
1. Use a sharp-less tool to arrange the cable clockwise along the fan but outside the two
screws.
2. Attach to the installed CPU.
3. Connect the properly seated cable to the mainboard for CPU temperature dissipation.
4. Reinstall the four screws surrounding the fan to fasten the heat sink. (Work at each other’s
opposite angle is recommended for equal attachment.)
