FIC A360 Disk Drives Subsystem, Power Subsystem, AC Power Adapter, Internal Battery Pack

Hardware Functional Overview

the sensor surface; electronic components are mounted on the other side. The sensitive area is protected by a layer of smooth and durable mylar.

The Synatics touch pad communicates with the host via a standard PS/2 mouse or trackball interface. It is fully compatible with the standard Microsoft mouse driver. The module connector includes the PS/2 signal pins, power supply pins and two connections for external button switches.

The Synatics touch pad includes a special “edge-motion” feature that allows the user to extend a drag operation when the finger reaches the edge of the sensor pad. The cursor continues to coast in the indicated direction when the finger is held against the edge.

4.14 Disk Drives Subsystem

The disk drives subsystem, implemented on the Motherboard and on the associated internal hard disk drive assembly and device bay, provides disk storage for all system software and user files.

The notebook is equipped with high capacity hard disk drive using Enhanced IDE controller with LBA (Logical Block Addressing) and Ultra DMA mode support.

The VT82C686B controller chip provides the Primary IDE controller for the internal hard disk, and the Secondary Master for the CD-ROM.

The floppy disk drive supports standard 3.5-inch 720KB and 1.44MB mini-diskettes while adding support for 1.2MB (3 Mode) mini-diskettes for Japanese market.

The notebook uses the 24X-speed IDE CD-ROM Drive that reads digital data stored on CD- ROM at 24 times faster rotational speed. The CD-ROM drive supports CD-DA transfer over ATAPI function that the host system can read CD audio data. The drive also supports Photo- CD Multi-session disc compatibility and Multimedia PC-3 specification compatibility. The notebook also could use the 8X+ speed IDE DVD-ROM Drive that reads DVD digital data stored on DVD-ROM at 8 times faster rotational speed.

4.15 Power Subsystem

The Power Subsystem consists of the following major sections:

4.15.1 AC Power Adapter

The computer is equipped with a 60W universal AC power adapter that converts AC voltage (100 to 240VAC, 50 to 60Hz) into DC voltage used to operate the notebook and charge the batteries.

4.15.2 Internal Battery Pack

The computer utilizes Nickel Metal Hydride (NiMH) or Lithium-Ion (Li-Ion) that provides DC power for the notebook and real time clock battery on the motherboard when the AC Adapter is not connected to the computer.

The normal charging time for the battery is around 2.5 hours when computer is turn off while it should take around 8 hours when the computer is running. Running time of battery is around 2 to 2.5 hours.
