This structure is used by GetPowerStatus function to relay the APM BIOS system
power status. Structure fields are direct representations of registers returned
by the APM Get Power Status call (see below):
*********************************************************************/
struct tagPOWER_STATUS {
BYTE BatteryStatus;
// Battery status bits changed since last call
// 00H High
// 01H Low
// 02H Critical
// 03H Charging
// FFH = Unknown
// All other values reserved
BYTE LineStatus;
// AC line status bits
// 00H Off-line
// 01H On-line
// 02H On backup power
// FFH = Unknown
// All other values reserved
BYTE BatteryCharge;
// % of battery left
// 0–100 = Percentage of full charge
// FFH = Unknown
// All other values reserved
BYTE BatteryFlags;
// Current battery status.
// bit 0 = 1 High
// bit 1 = 1 Low
// bit 2 = 1 Critical
// bit 3 = 1 Charging
// bit 7 = 1 No system battery
// All other bits reserved
// FFH = Unknown
// All other values reserved
WORD BatteryLife;
// Battery time left
// Bit 15 = 0 Time units are seconds
// 1 Time units are minutes
// Bits 14–0 = Number of seconds or minutes
// 0–7FFFH = Valid number of seconds
// 0–7FFEH = Valid number of minutes
// FFFFH = Battery life Unknown
