.TH WMACPI 1 "August 15 2004" .SH NAME wmacpi \- Battery status monitor for systems supporting ACPI .SH NAME acpi \- Query battery status for systems supporting ACPI .SH SYNOPSIS .B wmacpi [ .RI -c value ] [ .RI -d display ] [ .RI -m battery no ] [ .RI -s sample rate ] [ .RI -f ] [ .RI -v ] [ .RI -n ] [ .RI -w ] [ .RI -a samples ] [ .RI -V ] [ .RI -h ] .PP .B acpi [ .RI -a samples ] [ .RI -v ] [ .RI -V ] ] .RI -b ] [ .RI -r ] [ .RI -h ] .SH DESCRIPTION This manual page documents briefly the .B wmacpi command. .PP .B wmacpi 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 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 .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, in number of times per minute. Minimum is 1, ie once a minute, default is 20, maximum is 600. .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 \-f Force the use of capacity mode for calculating time remaining. By defalt .B wmacpi will use the reported values of remaining capacity and present rate to calculate the time remaining on battery. This flag will force the use of the remaining capacity and time samples to calculate the present rate of drain, and from there the time remaining. Note that this mode of calculation generally underreports the time remaining. This mode works around certain buggy ACPI BIOSes that fail to report the current rate. .TP .B \-w Run wmacpi in command line mode - this operates identically to .B acpi .. .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. Can be used more than once - each successive use increases the verbosity. .TP .B \-V Print the version information. .TP .B \-b Enable blinking of the power glyph when charging the batteries. .TP .B \-r Disable scrolling message. .TP .B \-h Display help. .TP .B acpi .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 .TP .B \-V Print the version information. .TP .B \-h Display help. .SH AUTHOR .B wmacpi was originally written by Tim Copperfield , then completely rewritten after 1.34 by Simon Fowler . .PP This manual page was originally written by Simon Richter for the Debian GNU/Linux system, and then updated by Simon Fowler. .br Last modification by Simon Fowler , 2004-08-15.
