It is equivalent to 44.Nm zzz. 45.Pp 46.It Fl b 47Display an integer value reflecting the current battery status. 48The values 0, 1, 2, 3, correspond to the 49.Dq high 50status, 51.Dq low 52status, 53.Dq critical 54status, 55.Dq charging 56status respectively. 57.Pp 58.It Fl a 59Display the current AC-line status as an integer value. The values 600 and 1 correspond to the 61.Dq off-line 62state or 63.Dq on-line 64state, respectively. 65.Pp 66.It Fl l 67Display the remaining battery percentage. If your laptop does not 68support this function, 255 is displayed. 69.Pp 70.It Fl s 71Display the status of the APM support as an integer value. The values 720 and 1 correspond to the 73.Dq enabled 74state or 75.Dq disabled 76state respecitively 77.Sh BUGS 78Some APM implementations do not support parameters needed by 79.Nm apm. 80On such systems, 81.Nm apm 82displays them as unknown. 83.Pp 84Some APM implementations cannot handle events such as pushing the 85power button or closing the cover. On such implementations, the system 86.Ar must 87be suspended 88.Ar only 89by using 90.Nm apm 91or 92.Nm zzz. 93.Sh SEE ALSO 94.Xr apm 4 , 95.Xr apmconf 8 96.Sh AUTHOR 97HOSOKAWA, Tatsumi <hosokawa@mt.cs.keio.ac.jp> (Keio Univ., Japan) 98
