3.Technical Information
3.1 System Overview
3.1.1 System Configuration
The main system is made up of a Main board, a SUB board, a LED board, a PAD board and a LID board.
The CPU operates at 1.6V, 1.35V(core)/2.5V; the main memory at 3.3V; the core logic at 3.3V/5V; and the
other main chips at 3.3V.
3.1.2 Power Supply System
The power supply used by the Main board is generated on the Main board based on the voltage from the AC adapter.
Power is supplied to the AC adapter and battery pack in that order when the RTC power is off or is in
suspend mode. When neither power supply can be accessed, power is supplied from the clock battery
(RTC battery).
