perspective of replacing components in the field. All replacement parts
are listed in Chapter 3, and removal and replacement procedures are
presented in Chapter 5.
The computer is a traditional clam shell design with a display unit and a
system unit.
The computer opens to reveal a backlighted LCD display and a
full-sized keyboard. The display is designed to open to 135o.
System Unit
The major components of the system unit are: the CPU cover, keyboard,
system board with processor, hard drive, diskette drive, memory expansion
board, battery pack and compartment, integrated trackball assembly,
Real-Time Clock battery, and PC Card (PCMCIA) ejector rails and
components.
Display Unit
The standard video subsystem consists of one of the following internal LCD
displays:
o 10.4-inch VGA CSTN display panel
o 10.4-inch VGA CTFT display panel
In addition, the video subsystem consists of:
o Cirrus Viking PCI Bus Graphics Accelerator with 1 MB EDO (two 70-ns
256kx 16) VRAM
o An inverter to supply AC power to the LCD backlight system
o A standard external VGA connector for use with CRTs and other VGA
compatible displays; also supported: external SVGA (maximum resolution
1024 x 768 x 256)
o A flex cable connecting the system board to the LCD display and the
inverter
o 48 KB of video ROM integrated into system ROM
