.TH WMACPI-NG 1 "July 11, 2003" .SH NAME wmacpi-ng \- Battery status monitor for systems supporting ACPI .SH NAME acpi-ng \- Query battery status for systems supporting ACPI .SH SYNOPSIS .B wmacpi-ng [ .RI -b ] [ .RI -c value ] [ .RI -d display ] [ .RI -m battery no ] [ .RI -s sample rate ] [ .RI -v ] ] .RI -n ] [ .RI -V ] [ .RI -h ] .PP .B acpi-ng [ .RI -a samples ] [ .RI -v ] [ .RI -V ] [ .RI -h ] .SH DESCRIPTION This manual page documents briefly the .B wmacpi-ng command. .PP .B wmacpi-ng is a program that displays the current battery status in a WindowMaker dock app, on systems that support Intel's Advanced Configuration and Power Interface specification (ACPI). .PP The program monitors a battery, displaying its current percentage charge via a bar and a numeric value. It also displays the current power status for the system, the time remaining (calculated based on the remaining battery capacity and the current rate of power usage), and a scrolling message with some hopefully useful information. .PP Clicking on the window cycles through the batteries that the ACPI system knows about. .PP .B acpi-ng queries the battery status from the command line. It prints the power status, the percentage remaining for each battery found, and the time remaining if the system is on battery, or the time remaining for each battery to reach full charge if the batteries are charging. .SH OPTIONS .B wmacpi-ng .TP .B \-b Make noise when battery is critical low (beep). .TP .B \-c percentage Set critical low alarm at % (default: 10%). .TP .B \-d display Set the X display to open the window on. .TP .B \-m battery number Set the battery to monitor initially. .TP .B \-s sample rate Set the rate at which to sample the ACPI data (default is 100, which translates to once every three seconds. 10 gives once every 30 seconds, 1 once every 300 seconds (five minutes), 1000 once every 0.3 seconds). .TP .B \-n Disable blinking power glyph when charging. Note that it still blinks when the battery reports its capacity state as critical. .TP .B \-v Increase the verbosity of the program. Can be used more than once - each successive use increases the verbosity. .TP .B \-V Print the version information. .TP .B \-h Display help. .TP .B acpi-ng .TP .B \-a num Average the time remaining over num samples. This greatly improves the accuracy of the reported time remaining. .TP .B \-v Increase the verbosity of the program, as for .B wmacpi-ng .TP .B \-V Print the version information. .TP .B \-h Display help. .TP .SH SEE ALSO .BR wmapm (1) .br .SH AUTHOR .B wmacpi as written by Tim Copperfield . .B wmacpi-ng is a reworking of .B wmacpi 1.34 to support recent kernel versions, performed by Simon Fowler . .PP This manual page was originally written by Simon Richter for the Debian GNU/Linux system, and then updated for .B wmacpi-ng by Simon Fowler. .br Last modification by Simon Fowler , 2003-07-11.
