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.
