Preface
This service and reference manual contains the technical information necessary to set up and
maintain the NEC Versa®6060 notebook computer.
The manual also provides hardware and interface information for users who need an over-
view of the system design. The manual is written for NEC-trained customer engineers, sys-
tem analysts, service center personnel, and dealers.
The manual is organized as follows:
Section 1 Technical Information, provides an overview of the hardware and interface
components. System specifications are listed including computer dimensions, weight, envi-
ronment, safety compliance, power consumption, and system memory specifications.
Section 2  Setup and Operation,takes the authorized service technician or dealer from
unpacking to setup and operation. The section includes a description of operating controls,
setting parameters and accessing the NECCSD bulletin board system (BBS).
Section 3  Troubleshooting, lists troubleshooting procedures as well as helpful
servicing hints.
Section 4  Field Service Guidelines,provides disassembly and assembly procedures,
and an exploded-view diagram of the NEC Versa system with part numbers.
Appendix A  Connector Locations and Pin Assignments,provides a list of the main
board internal connector pin assignments and a list of external pin assignments.
Appendix B  Video Modes,lists NEC Versa supported video modes.
An Index is included for convenience.

Technical Information
The NEC Versa 6060 notebook computer is lightweight, compact, and fully IBM compati-
ble. This is the latest addition to the NEC Versa family.
NOTE
This service manual covers only the NEC
Versa 6060 model. All figures in this manual re-
flect this model.
Figure 1-1 NEC Versa 6060 Notebook
This section of the manual provides system configuration information, including an over-
view of hardware and interface components. See the following table for a systems specific
breakdown of hardware.

HARDWARE OVERVIEW—FRONT
Take a moment to become familiar with the location and function of controls located on the
front of the system.
Liquid Crystal Display (LCD)
The LCD operates with NeoMagic NMG4 VGA controller. The controller supports XGA,
uses a 64-bit accelerator with a Peripheral Component Interconnect (PCI) interface.
The NEC Versa 6060 LCD features the following:

12.1-inch Thin Film Transistor (TFT) CCFT Super VGA (SVGA) single-backlite
color

0.306 mm dot pitch

16-bit digital interface

800 x 600 resolution

64K colors.
Additional LCD panel features:

Power LED that indicates the current power status. This LED is visible with the
LCD panel opened or closed.

Slide switch that adjusts screen brightness.

Technical Information 1-3
Figure 1-2 LCD Panel
Another video feature includes a CRT port on the system's rear panel that allows the user to
connect an optional monochrome or color external display to the system. The computer can
support the LCD and external display simultaneously.
Power-saving features for controlling the LCD's backlighting include the ROM-based hot
key combination Fn F5, and Auto Setup power management settings. See Section 2, Setup
and Operation, for information on using these settings. In addition, the automatic LCD
status feature conserves the backlight. When the LCD is closed the backlight shuts off
automatically, saving battery power.
Power Button
Slide the Power button to the right to power on and power off the computer. The Power
button is a “smart” switch, meaning that it recognizes when the system is in Suspend mode.
If in Suspend mode, you cannot power off until you press the Suspend button again to bring
the system out of Suspend mode.

1-4 Technical Information
Figure 1-3 Power Button Location
LCD Status Bar and Power Indicator
The LCD status bar is situated right below the LCD screen. It provides an easy way to de-
tect system status. Different graphic icons appear on the LCD bar indicating that a device is
accessed, an operation performed, or a power mode activated. The graphic icons displayed
on the LCD bar resemble either their physical characteristics or their primary function. See
the LCD Status Bar figure shown next, and the descriptions that follow for the specific
meaning of each icon.
The power indicator is located just above and to the right of the status bar. The power indi-
cator lights green when computer power is on, blinks green when in Suspend mode and
blinks amber to indicate that the battery power is low.
Figure 1-4 System Status Bar

Technical Information 1-5
Status Icons
The following list defines the status icons displayed in the system status bar.

Suspend — appears when the system is in Suspend mode. Suspend mode con-
serves system power by shutting down devices in the system while retaining data
and system status.

Power Management — shows the current power management mode in use, in-
cluding Off, Custom, High Performance or Longest Life.

Diskette or Versa Bay II SuperDiskLS-120 drive — appears when the NEC
Versa writes data to or retrieves data from a diskette.

Hard Disk — shows when the NEC Versa writes data to or retrieves data from
the hard disk.

Caps Lock — appears when Caps Lock is in effect.

Scroll Lock — shows that Scroll Lock is in effect.

Num Lock — appears when Num Lock is in effect. Num Lock lets the user enter
numbers for calculations via the numeric keypad.

Battery Status — displays the total percentage of battery power available.
Battery 1 appears when you have the main battery installed in the battery bay.
Battery 2 appears when you have an optional battery installed in the
VersaBay II.
Keyboard
The built-in, 83-key keyboard (U.S.) or 79-key keyboard (UK and Germany) uses the stan-
dard QWERTY format. The keyboard provides 12 function keys and 7 cursor control keys,
with an Fn key for ROM-based key functions. The numeric keypad is embedded in the stan-
dard key layout.

1-6 Technical Information
Figure 1-5 Keyboard Layout
NEC VersaGlide
The NEC VersaGlide is a built-in mechanism that functions as the system’s mouse. It con-
trols the on-screen pointer (cursor). To use the VersaGlide, move your finger across the
NEC VersaGlide pad, and the cursor follows. The buttons below the NEC VersaGlide al-
low the user to select or deselect menu items. Tap and double-tap are supported on the
VersaGlide pad.
If an external mouse is installed, the NEC VersaGlide is deactivated. A serial mouse is not
supported.
Figure 1-6 VersaGlide Location

Technical Information 1-7
Diskette Drive, CD-ROM Reader and the NEC VersaBay II
A standard 1.44-MB diskette drive or Versa Bay II SuperDiskLS-120 drive comes in-
stalled in the VersaBay II slot on the front of the computer. The VersaBay II expansion slot
lets the user replace the standard diskette drive with the 20X CD-ROM reader that also
ships with the system. In addition to the CD-ROM reader, the VersaBay II accepts NEC
options including a second battery pack, or an additional hard disk.
Figure 1-7 NEC VersaBay II Location
Infrared (IR) Assembly
The IR assembly consists of a small board with one infrared LED and one pin photo diode,
attached to the CPU board. The board allows the NEC Versa computer to communicate
with other infrared-ready computers. For example, the infrared port allows the user to
transfer files between the NEC Versa and an IR-equipped computer, or print to an IR-
equipped printer without using cables.
NOTE
Do not use the IR port directly under fluo-
rescent or incandescent light.

1-8 Technical Information
HARDWARE OVERVIEW—RIGHT SIDE
Review the following section for a description of the hardware on the right side of the NEC
Versa.
Figure 1-8 Right Side Features

Volume Control — Allows you to control the speaker volume.

Headphones/Line-Out — Lets you connect external headphones, speakers or
audio system to your NEC Versa system. Using this port disables the built-in
system speakers.

Line-In — Lets you use another audio system, like a home stereo, as an input
source. Use a the cable to connect to the Line-Out port on the other audio sys-
tem to record or play.

Microphone (MIC) — Allows you to connect an external microphone for
monophonic recording or amplification through the unit. Plugging in an external
microphone disables the built-in microphone.

Hard Disk Drive Bay Cover — The hard disk drive bay contains the removable
hard disk drive. Depending on your NEC Versa’s configuration, it contains a
2.1-GB hard disk drive or 3.2-GB hard disk drive.

Kensington Lock Connection — Lets you provide added security by installing
an optional Kensington Lock.

USB Port — The Universal Serial Bus (USB) allows the connection of up to
127 peripheral devices (printers, monitors, scanners, etc.) to your NEC Versa.

Fan Exhaust Port — This port provides air flow from the interior of the com-
puter to assist in keeping the system running at optimal performance.
