SYSTEM_POWER_STATUS

The SYSTEM_POWER_STATUS structure contains information about the power status of the system.

typedef struct _SYSTEM_POWER_STATUS {
BYTE ACLineStatus;
BYTE BatteryFlag;
BYTE BatteryLifePercent;
BYTE Reserved1;
DWORD BatteryLifeTime;
DWORD BatteryFullLifeTime;
} SYSTEM_POWER_STATUS;
typedef struct SYSTEM_POWER_STATUS *LPSYSTEM_POWER_STATUS;

Members

ACLineStatus

AC power status. This parameter can be one of the following values:

Value	Meaning
0	Offline
	Online
255	Unknown status.

All other values are reserved.

BatteryFlag

Battery charge status. This parameter can be a combination of the following values:

Value	Meaning
	High
	Low
4	Critical
8	Charging
128	No system battery
255	Unknown status

All other values are reserved.

BatteryLifePercent

Percentage of full battery charge remaining. This member can be a value in the range 0 to 100, or 255 if status is unknown. All other values are reserved.

Reserved1

Reserved; must be zero.

BatteryLifeTime

Number of seconds of battery life remaining, or 0xFFFFFFFF if remaining seconds are unknown.

BatteryFullLifeTime

Number of seconds of battery life when at full charge, or 0xFFFFFFFF if full lifetime is unknown.

Remarks

Windows 95 is only capable of estimating BatteryFullTime based on calculations on BatteryLifeTime and BatteryLifePercent. Without smart battery subsystems, this value may not be accurate enough to be useful.
