Smart Battery Management System

Windows OS Interface

Device Presence
ADLINK COM Express Type 10 modules feature a BIOS that fully supports all Smart Battery communications using
existing interfaces defined in the COM Express specification and are fully compatible with the integrated Smart
Battery Management System. The BIOS reports the presence of a Smart Battery device to the OS. In Windows, the
battery power subsystem information is listed in the Device Manager under the "Batteries" category. The system
BIOS will check the current system configuration and then report back to the OS. There are three possibilities for
the battery report information.
9.5.2.
No Battery Power Subsystem Present
The system BIOS checks for the presence of a charger, selector or system manager. If there is no device attached,
it will only report the presence of an AC adapter to the OS.
9.5.3.
Battery Present
The system BIOS will report an AC adapter and two battery devices to the OS
9.5.4.
Battery State Notification
The system BIOS is notified of the state (AC power or battery mode) when it receives an SMBALERT# as a SCI
event. An alert may be sent to update the charging state, remaining battery capacity, or presence of an AC adapter.
The OS can also query the system BIOS to update the battery power information. Placing the cursor over the
battery state icon will cause the OS to update the battery power information.
When an AC adapter is inserted or removed, the battery state icon in the taskbar will change to indicate the current
state. To display the battery state icon in the taskbar, enable the option "Always show icon on the taskbar" from the
"Advanced" tab of "Power Options Properties".
