Chapter 7 Optimizing your HP Jornada 135

Under normal circumstances, the main battery will provide up to 7 hours of continuous use without recharging. Actual battery life will vary depending on screen brightness, what applications you use, and operating conditions. When the main battery runs very low, your HP Jornada will shut down, and you will be unable to restart it until you replace the main battery, recharge the battery, or connect to AC power.

When you replace the main battery, your new battery must be charged before your HP Jornada will turn on. For information on charging the main battery, refer to the Connecting the AC adapter section in chapter 2.

Ensure that the backup battery is in good condition before you remove the main battery. If the backup battery is low or you are not sure, connect to AC power before you remove the main battery.
