***Info;...
***Versions:...
***Features:
o   Provides system activity monitoring, peripheral control, power 
    supply control, mode timers, and general purpose I/O for 
    laptop/notebook power management
o   Five operation modes:
    - On Mode
    - Doze Mode
    - Sleep Mode
    - Suspend Mode
    - Off Mode
o   Independent programmable timers for power saving modes
o   independent programmable timers for LCD and backlight control
o   Ten individual power control outputs
    - Three for LCD power
    - Seven general purpose for peripherals
o   Four "low battery" warning monitors: two standard and two 
    optional
o   Multiple power-on sources from Suspend/Off Mode:
    - Pushbutton
    - RTC alarm
    - Modem ring
o   AC power monitoring to disable PMU function
o   Refresh support in suspend Mode
