BatteryStatus

Unimplemented. (Deprecated in Mac OS X v10.0. Use I/O Kit instead; see I/O Kit Fundamentals.)

OSErr BatteryStatus (
   Byte *status,
   Byte *power
);

Parameters

Status

On return, the referenced value holds the status of the battery charger and the voltage level of the battery, described in BatteryByte Bits.The connChangedBit is set when the charger connection is changed—either connected or disconnected. When this bit is set, the Power Manager IC sends an interrupt to the CPU.

The batteryLowBit is set whenever battery voltage drops below the value set in parameter RAM. The Power Manager IC sends an interrupt to the CPU once every second when battery voltage is low.If the batteryDeadBit were set, it would indicate a dead battery; however, the Power Manager automatically shuts the system down when the battery voltage drops below a preset level, so this bit is always 0.

Power

On return, the referenced value contains the Power value you can use to estimate the battery voltage:

voltage = ((Power/100) + 5.12) volts

Due to the nature of lead-acid batteries, the battery power remaining is difficult to measure accurately. Temperature, load, and other factors can alter the measured voltage by 30 percent or more. The Power Manager takes as many of these factors into account as possible, but the voltage measurement can still be in error by up to 10 percent. The measurement is most accurate when the Macintosh Portable has been in the sleep state for at least 30 minutes.

Return Value

A result code. See “Power Manager Result Codes.”
