Battery State Notification
The system BIOS is notified of the state of the battery power subsystem (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".
