Acer Travelmate 5000 Maintenance Manual

							All members of the TM5000 family come standard with 8MB of 70-ns
page-interleaved, DRAM on the main board (expandable to 32MB with
user -installable RAM Expansion Boards based on 16M DRAM technology). 
The Basic Input Output System (BIOS) firmware for the main system and
for the VGA BIOS is stored on a 256K x 8 Flash reprogrammable Flash
ROM. A Boot Block feature permits downloading of new BIOS changes
without having to physically replace the ROMs. Execution from ROM is
initially 8-bits wide but 32-bit performance is available when using the
Shadow ROM feature.      
To take full advantage of the Pentium’s powerful multi-tasking capabilities,
the TM5000 series implements a 50MHZ, 64-bit high speed system bus that
interconnects the critical CPU, Memory and hard drive components. The
50-MHz system bus drives a 33 MHz, 32-bit, Peripheral Components
Interface (PCI) bus that supports the video subsystem, expansion
subsystem with other higher speed peripherals. The PCI bus also drives a
conventional 8MHz AT Bus for compatibility with AT peripherals (onboard
1.44MB floppy, keyboard, pointing device, etc.). 
1.2.1 MultiMedia Features
As standard features, the notebooks contain powerful audio and video
multimedia capabilities. A built-in SoundBlaster compatible sound board,
Jazz 16 Sound Software, plus internal speaker and microphone, and audio
input and output jacks give the notebooks a wide range of sound
capabilities.
The notebooks also offer powerful new video features on the PCI Expansion
Bus including the MotionVideo
tm Architecture (MVATM). MVATM supports
storage and playback of video clips (320 x 240 clips can be played back at
30 fps with 24 bpp color quality). The notebook’s video controller has a
feature interface that is VESA VAFC compatible enabling a system to
provide live video overlay capability.
A control/data interface is also available on the PCI bus that allows an
implementation of NTSC/PAL (commercial TV) output required to display
graphics or video on standard TVs.

							1.2.2 Dual Intelligent Battery Packs 
The TM5000 notebook series support the use of two hot plugable intelligent
battery packs (with front panel charge remaining indicators) that allow for
battery removal and replacement while the system is operational (as long as
one battery contains a partial charge). The notebooks use rechargeable
Lithium-Ion (Li-Ion) batteries.  These battery packs are ejected from the
front of the notebook using battery eject switches located just above the
keyboard (See Figure 1-4).
NOTE: When battery is 100% charged, all 
LEDs extinguish; also LEDs extinguish when 
battery  is removed from unit.
