Battery Charge Monitor applet, shown in Figure 1, displays the charge status of your portable computer battery. To learn how to add this applet to a Panel, see .

Note: In order for Battery Charge Monitor to function correctly, your computer must have been configured to support Advanced Power Management.

Figure 1. Battery Charge Monitor

Usage

Battery Charge Monitor just sits in your panel monitoring the status of your computer battery. By left-clicking on the applet you can toggle the view between Readout View and Graph View described in the section called Readout View and the section called Graph View respectively.

Readout View

Readout View, the default mode of view, displays the current battery status in an iconic and textual format. In this mode Battery Charge Monitor displays the following information:

Battery Icon

The iconic representation of a battery on the left of the applet, shows how fully charged your battery is currently. The coloured area of the battery represents the ammount of charge left in your battery, with the top of the battery representing 100% charged.

The colour of the battery changes when the charge drops below the current Low Charge Threshold (see the section called Properties — General). The default colour of the battery is green in a normal state and red when it drops below the Low Charge Threshold.

When your computer is attached to the power supply, a small lightning bolt appears on the battery representation to indicate that the battery is attached to the power supply and is in a charging state. An example of this is shown in Figure 2. You can also configure the battery to change colour when it is or isn't connected to the power supply, see the section called Properties — Readout for further details on this feature.

Percentage Remaining

The percentage readout on the top right of the applet represents how fully charged your computer battery is currently.

Time Remaining

The time remaining readout on the bottom right of the applet shows how much running time the battery has left. The time is shown in hours and minutes.

Graph View

Graph View displays the percentage of charge remaining in your battery as a moving graph. The horizontal axis represents time and the vertical axis represents charge percentage with 100% charged being the top of the graph. By default the graph is green when your computer is connected to the power supply and blue when it isn't. The graph also changes colour when the charge drops below the Low Charge Threshold (see the section called Properties — General) the default colour in this case is red.

Right-Click Pop-Up Menu Items

In addition to the standard menu items (see ), the right-click pop-up menu has the following item:

  • Properties... — This menu item opens the Properties dialog (see the section called Properties) which allows you to customize the appearance and behavior of this applet.

Properties

You can configure Battery Charge Monitor applet by right-clicking on the applet and choosing the Properties... menu item. This will open the Properties dialog, with four groups of configurable items arranged in the following tabbed pages: General, Readout, Graph and Battery Charge Messages.

Properties — General

Figure 4. Properties Dialogue — General

  • Follow Panel Size — instructs Battery Charge Monitor to resize when the panel changes size. It is checked on by default. In order for Applet Height and Applet Width settings to take affect, it must be unchecked.

  • Applet Height & Applet Width — these two spin buttons allow you to specify the dimensions of Battery Charge Monitor exactly in pixels. In order for these settings to take affect, Follow Panel Size must be unchecked. The default values are both set to 48.

    Note: Setting these values very small (below 28 pixels) results in the battery icon not being displayed due to lack of space.

  • Update Interval — specifies in seconds how often Battery Charge Monitor refreshes the battery charge information it displays. The default setting is two seconds.

  • Low Charge Threshold — is a percentage value of the battery charge that Battery Charge Monitor uses to optionally display a warning, it then considers the battery to have little power remaining. For example this information is used to decide when to change the colour of the battery icon in Readout View. The default value is 25.

  • Applet Mode — the two Readout and Graph checkboxes are another way of toggling between Readout View and Graph View discussed in the section called Readout View and the section called Graph View.

Properties — Readout

The settings on this tab only affect Battery Charge Monitor when it is in Readout View described in the section called Readout View.

All of the coloured rectangles on this tab can be left clicked on to display the GNOME colour wheel. This enables you to choose colours that you may prefer more than the defaults.

Figure 5. Properties Dialogue — Readout

  • AC-On Battery Color — specifies the colour of the battery icon in Readout view when your computer is connected to the AC power supply. The default colour is green.

  • AC-Off Battery Color — specifies the colour of the battery icon in Readout View when your computer is not connected to the AC power supply. The default colour is green.

  • Low Battery Color — specifies the colour of the battery icon in Readout View when the charge percentage rate drops below the Low Charge Threshold (see the section called Properties — General). The default colour is red.

Properties — Graph

The settings on this tab only affect Battery Charge Monitor when it is in Graph View described in the section called Graph View.

All of the coloured rectangles on this tab can be left clicked on to display the GNOME colour wheel. This enables you to choose colours that you may prefer more than the defaults.

Figure 6. Properties Dialogue — Graph

  • AC-On Battery Color — specifies the colour of the graph when your computer is connected to the AC power supply. The default colour is green.

  • AC-Off Battery Color —: specifies the colour of the graph when your computer is not connected to the AC power supply. The default colour is blue.

  • Graph Battery Low Color — specifies the colour of the graph when the charge percentage rate drops below the Low Charge Threshold. The default colour is red.

  • Graph Tick Color — specifies the colour of the graph division lines on the graph which mark the 25%, 50% and 75% charge points. The default colour is dark grey.

  • Graph Direction — specifies which direction the graph moves over time. The default direction is Right to Left.

Properties — Battery Charge Messages

Figure 7. Properties Dialogue — Battery Charge Messages

  • Warn in the battery charge dips below — specifies the charge percentage at which Battery Charge Monitor shows a warning dialogue box that the battery is at a low charge. This warning is only displayed if Enable Low Battery Warning is checked. The default setting is 5%.

  • Enable Low Battery Warning — specifies if Battery Charge Monitor should display a dialogue box warning that the battery charge has dropped below the charge percentage specified in the Warn if the battery charge dips below setting. The default value is checked.

  • Enable Full-Charge Notification — specifies if Battery Charge Monitor should display a dialogue box when the battery has reached its 100% charged rate. The default value is unchecked.

Further Information

For more information on the Properties dialog, including descriptions of the OK, Apply, Cancel, and Help buttons, see .

Known Bugs and Limitations

One oddity is if you start Battery Charge Monitor on a computer that has no Advanced Power Management support. This causes the Low Battery Warning dialogue box to be displayed which may be mis-leading.
