4.12 Audio Subsystem

The audio subsystem is integrated inside the South Bridge chip on the motherboard. Refer to
the System Core Logic section of this chapter.

An internal two-way mini speaker and microphone provide the notebook with mobile sound
generation and recording capabilities. In addition, a set of 3.5mm bayonet socket (1/8”
minijack) connectors allow for external microphone, line inputs, and headphone outputs.

4.13 Keyboard and Pointing Device

The Keyboard Subsystem of the notebook is implemented on the Motherboard and Keyboard
Assembly using the Mitsubishi 38869M8 keyboard controller chip and the Phoenix
MultiKey/M3886L keyboard controller firmware. This chip controls the internal built-in
keyboard, the built-in touchpad pointing device, as well as the external PS/2 keyboard and
mouse port. The keyboard controller allows simultaneous use of both the internal and external
keyboard and PS/2 mouse.

The M285 membrane keyboard is an 86-key IBM 101-key enhanced compatible keyboard
with standard characters and 12 function keys including an embedded numeric keypad. See
Chapter 1 for more information.
