It is equivalent to 43.Nm zzz. 44.Pp 45.It Fl b 46Display an integer value reflecting the current battery status. 47The values 0, 1, 2, 3, correspond to the 48.Dq high 49status, 50.Dq low 51status, 52.Dq critical 53status, 54.Dq charging 55status respectively. 56.Pp 57.It Fl a 58Display the current AC-line status as an integer value. The values 590 and 1 correspond to the 60.Dq off-line 61state and 62.Dq on-line 63state, respectively. 64.Pp 65.It Fl l 66Display the remaining battery percentage. If your laptop does not 67support this function, 255 is displayed. 68.Sh BUGS 69Some APM implementations do not support parameters needed by 70.Nm apm. 71On such systems, 72.Nm apm 73displays them as unknown. 74.Pp 75Some APM implementations cannot handle events such as pushing the 76power button or closing the cover. On such implementations, the system 77.Ar must 78be suspended 79.Ar only 80by using 81.Nm apm 82or 83.Nm zzz. 84.Sh SEE ALSO 85.Xr apm 4 , 86.Xr apmconf 8 87.Sh AUTHOR 88HOSOKAWA, Tatsumi <hosokawa@mt.cs.keio.ac.jp> (Keio Univ., Japan) 89
