HP Jornada 430/430se Palm-size PC - Battery and Battery Backup

Introduction
Because the data and files you save on the product are stored in random-access memory (RAM), it is extremely important that you maintain a continuous power supply to the product at all times. If the product runs out of power, all information you have entered is lost. Although the Windows CE operating system and programs are stored in read-only memory (ROM) and cannot be erased, any custom settings and programs you have added are lost.
The product uses a rechargeable lithium-ion battery, which supplies power whenever the product is not connected to AC power. Under normal operating conditions, the battery should last for up to 6 hours of continuous use without recharging. Battery life varies, however, depending on how you use the product.
When taking out the main battery, keep in mind that when the product is without power, data retention is guaranteed for only 1 minute, and only if the backup battery level is “good” on the Status tab of the Power panel. You do not need to take out the main battery except to replace it with a spare battery (F1287A).
Installing the battery
The main battery powers the product when it is not connected to AC power. The battery fits into a compartment on the bottom of the product.
To install the main battery
  1. Unpack the main battery.
  2. Open the battery compartment. Insert the tip of the stylus into the battery door release. Slide the battery door open toward the bottom of the product.
    Figure : Slide the battery door open
  3. Insert the battery pack into the battery compartment. If the battery does not slide in easily, check the battery orientation and try again. If you are putting the battery in correctly, you do not need to force it.
    Figure : Insert the battery pack into the battery compartment
  4. Slide the battery door closed until it locks into place. The product turns on automatically. The first screen you see is the Hardware Button instruction screen. It describes the location and function of the hardware buttons.
  5. Press the Action button.
  6. Connect to AC power. (Click here to see "Connecting the travel cable and AC adapter.")
Follow this procedure when you replace the main battery with a spare battery (accessory F1287A).
  caution:
Do not replace your main battery when the backup battery is low or data loss may occur. Keep in mind that when the product is without power, data retention is guaranteed for only 1 minute, and only if the backup battery level is “good” on the Status tab.
About the backup battery
The rechargeable backup battery is a permanent part of the product, so you do not need to install or replace it. The backup battery is being charged automatically when the product is connected to AC power.
Make sure you connect to AC power to charge as soon as you see a backup battery low warning. Continue to charge until the backup battery level is “good” on the Status tab.
Charging the main and backup batteries
Charge the battery overnight by connecting the AC adapter.
The AC Charging LED indicates the charging status of the main battery:
  • Amber: Indicates that the battery is charging (connected to AC power).
  • Green: Indicates that the battery is fully charged.
      note:
    The AC Charging LED is illuminated only if the product is connected to AC power.
While charging, you may see backup battery low messages. These do not appear once the battery is fully charged. If you do not charge overnight, the backup battery low messages may continue to appear. You can use the product while charging.
The switch on the battery does not have any electrical function. When the battery is drained, you can flip the switch so that the red dot shows. This can help to remind you that the battery needs to be recharged, which is convenient if you have other batteries.
Viewing the remaining battery power
  • To view the remaining battery power:
  • Tap Start, then HP settings.
    OR
  • Hold the Start button for 1 second.
The remaining battery power is displayed on a status bar at the bottom of the Settings tab.
Connecting the travel cable and AC adapter
You can operate the product on AC power using the AC adapter. The AC adapter accepts voltages from 100 volts (V) to 240 V, so you can use it anywhere in the world. However, you may need a plug adapter to accommodate different electrical outlets.

To connect to AC power
  1. Unpack the AC adapter, and then connect the power cable and the DC cable to the AC adapter body.
  2. Connect the DC cable to the travel cable connector.
  3. Plug the travel cable connector into the product.
  4. Plug the power cable into an AC power outlet.
Use the AC adapter to plug the product into external power whenever possible, especially when connecting to a desktop computer or other peripheral, or when letting the LED indicator flash for extended time periods.
Using Power Properties
Power Properties displays information about the current state of your battery and allows you to control options that can conserve battery power.
To use Power Properties
  1. Tap the Start button, tap Settings, and then tap Power.
    OR
    If the power plug icon is on the taskbar, double-tap it.
  2. Tap the Status, Power, or Dimming tab.

Using the Power tab
The Power tab lets you customize how and when the product suspends operation to help maximize battery life:
  • Touch screen to power on: Select this option to allow the product to awake from suspend mode when you tap the screen or hard icon panel. The Touch screen to power on option is checked by default. When you clear this option, you are no longer able to use the hard icon panel to turn on the product.
  • Suspend while on battery power: To conserve battery power, the product automatically suspends operation after a period of continuous idle time while running on battery power. Select the amount of idle time from the drop-down list.
  • Enable suspend while on AC power: Select this option to automatically suspend operation after a period of continuous idle time while running on AC power. Select the amount of idle time from the drop-down list.
Using the Dimming tab
The Dimming tab lets you control backlight dimming to help conserve battery power:
  • Automatically dim while on Battery Power: By default, this option is selected with an idle time of 1 minute. It conserves battery power by automatically dimming the backlight.
  • Automatically dim while on AC Power: Select this option to automatically dim the backlight after a period of continuous idle time while running on AC power. Select the amount of idle time from the drop-down list.
Optimizing battery life
The following tips can optimize battery life, ensuring the longest use of the product between charges:
  • Shorten auto-suspend time. To set auto-suspend time: from the Start menu, tap Settings, tap Power, and then tap the Power tab.
  • Set the display to dim automatically after a short time. To set dimming: from the Start menu, tap Settings, tap Power, and then tap the Dimming tab.
  • Minimize brightness and use contrast to increase readability. To set brightness and contrast: from the Start menu, tap HP settings.
  • Turn off sounds you do not need or mute the system speaker. To mute sounds: from the Start menu, tap HP settings.
  • Connect to AC power when connected to any peripherals requiring power.
  • Connect to AC power when connected to your desktop computer.
