# xapm(1)

display Advanced Power Management (APM) BIOS information

## NAME

xapm - display Advanced Power Management (APM) BIOS information

## SYNOPSIS

**xapm \[ ... \]**

## DESCRIPTION

**xapm** puts up an X window that displays the remaining battery life. The left side of the window contains a printed time or percentage; the right side of the window contains a bar indicating the percentage. Clicking on the left side of the window will toggle the display between time and percentage.

## OPTIONS AND RESOURCES

In addition to standard Xt options, the following options are available:

- **-V**

  Print the program version number and exit.

- **-highcolor** *color*

  The color of the bar when the battery percentage is above *highvalue*. Defaults to "green". (\*highColor)

- **-lowcolor** *color*

  The color of the bar when the battery percentage is between *lowvalue* and *highvalue*. Defaults to "yellow". (\*lowColor)

- **-criticalcolor** *color*

  The color of the bar when the battery percentage is below *lowvalue*. Defaults to "red". This color is also used to flash the alphanumeric part of the display when the power status is critical. (\*criticalCOlor)

- **-highvalue** *highvalue*

  Set *highvalue*. The default is 50. (\*highValue)

- **-lowvalue** *lowvalue*

  Set *lowvalue*. The default is 10. (\*lowValue)

- **-chargingcolor** *color*

  The color of the printed display when charging. The default is "blue". Use **-foreground** to change the color used when on battery power. (\*chargingColor)

- **-delay** *delay*

  Sets the number of seconds delay between each update. The default is 1. (\*delay)

- **-percent**

  Display percentage on startup, instead of time remaining. (\*percent, boolean)

- **-percentauto**

  Swap automatically between displaying percentage and displaying the time remaining. When on ac power, display percentage, when on battery power, display the time remaining.

## BUGS

There is no way to inhibit the alphanumeric display or the bar display. When the battery percentage is low, using a bright color to warn you of impending doom may be futile because the bar is too short.  Because of the form widget's desire to maintain proportions, dynamic resizing of the window may not do what you want it to do.
