3-10 Hardware Functional Overview
The built-in controller can support any industry standard 2.5-inch IDE hard disk drive at
19mm or 17mm height. Setting up the hard disk type is done automatically by the CMOS
Setup program. Setup auto-detects the installed hard disk type settings for optimized per-
formance.
NOTE: Do not move the notebook when the
HDD LED is activated. This protects the hard
disk drive from any accidental damage or loss of
data.
DISKETTE DRIVE SUBSYSTEM
The Diskette Drive Subsystem consists of a FDD controller provided by SMC 37C665IR
and the built-in floppy disk drive. The floppy disk drive supports standard 3.5-inch
720KB and 1.44 MB mini-diskettes.
POINTING DEVICE SUBSYSTEM
The pointing device subsystem consists of the VersaGlide device on the system top cover
assembly, and a pre-programmed Mitsubishi M38813M4 micro-controller that interfaces the
mouse device to the system board. An external PS/2 port also supports the use of an exter-
nal PS/2 compatible mouse which the system automatically detects during system power up
and then disables the internal VersaGlide.
POWER SUBSYSTEM
The Power Subsystem consists of the following major sections:
External AC Power Adapter
Internal Battery Pack
Power Board (on system board)
LCD Inverter Board (in LCD Panel Assembly)
Power Conservation Logic (part of system board)
AC Power Adapter
The computer is equipped with a universal AC power adapter that converts AC voltage (90
to 265VAC, 47 to 63Hz) into DC voltage used to operate the notebook and charge the
batteries.
