 Wireless LAN  
Some computers in this series are equipped with a Wireless LAN card. This WLAN module 
may come in with the following types (depending on the model): 
  Intel 802.11a/b/g/n (Shirley Peak 1x2; Shirley Peak 3x3) 
  Intel 802.16e & 80211a/b/g/n (Echo Peak 1x2) 
  Atheros HB93, Atheros HB95 – HMC type;  Atheros XB91, Atheros XB95 – FMC type 
  Realtek 802.11b/g (RTL8187B) – FMC type, Realtek 802.11b/g (RTL818\
7SE) – HMC 
type, 802.11b/g/n (RTL8191SE) 
 
  Internal Modem (BTO) 
Some models are equipped with the integrated modem. The integrated modem provides 
capability for data and fax communications that support the V.90 (V.92) standards and 
includes a modem jack for connection to the telephone line. Please note that both the V.\
90 
and V.92 standards are only supported in the USA, Canada, United Kingdom\
, France, 
Germany and Australia - only the V.90 standard is supported in other regions\
. You should 
also be aware that the speed of data and fax transfer will depend on the\
 analog telephone 
line conditions. The integrated model is only installed as a standard device in some markets. 
This internal modem comes with MDC 1.5 solution (Azalia interface).

1.4  Power Supply 
The power supply unit provides constant voltage 19V for the system board and performs the 
following functions: 
1.  Power input monitor 
   Checks whether the AC adapter (DC power supply) is connected to the co\
mputer. 
   Checks whether the battery pack is connected to the computer. 
   Monitors the DC power supply input voltage (AC Adapter output voltage)\
. 
2.  Power supplys internal control 
   Turns on and off the battery pack charging power supply. 
   Issues a charging current instruction to the  PWM control IC of the battery pack charging 
power supply. 
   Controls the supply of DC power supply input (AC Adapter output) to the power supply 
unit. 
   Controls the supply of power to the system block (load/logic circuit side). 
   Controls forced shutdown if the power supply malfunctions. 
3.  Logic circuit control 
   Instructs the gate array to enable/disable tuning the power on. 
   Controls power-on/off operation. 
4.  Status display 
   Battery indicator (in green or amber). 
   DC-IN indicator (in green color)  
5.  External interface 
   Performs communication through the I2C bus (via the internal EC/KBC). 
   Transfers the power supply operation mode.

6. Output monitor 
   Monitors the voltage output to the system block (load/logic circuit side). 
   Monitors the voltage, over voltage, input/output current of the battery \
pack. 
   Monitors the internal temperature of the battery pack. 
   Monitors the supply voltage from the AC adapter.
