Charging the Battery with the HP Desktop Cradle and USB
Cable
An alternative method of charging the HP iPAQ is to charge the device by
using a USB cable. However, because this charging method drains the
host battery (i.e., laptop), you must enable USB charging on the HP
iPAQ before you can charge the device.
To charge your HP iPAQ using the HP Desktop Cradle and USB Cable:
1.
Turn on USB charging by tapping Start > Settings > System
tab > Power on the HP iPAQ.
2.
Select the USB Charging tab, and then check Use USB
Charging.
3. Tap OK once USB Charging has been enabled.
4. Connect one end of the USB sync cable to the bottom of the
HP iPAQ.
5. Connect the USB cable to an available USB port on your USB
powered device, such as a laptop computer.
NOTE: The HP iPAQ charges slower when using an USB cable than with
an AC Adapter.
If the battery won't stay charged, try the following:
• Always keep the HP iPAQ connected to the AC Adapter when you
are not using it.
•
In the backlight settings, adjust the bar to a lower level to conserve
more battery power.
•
Turn off Bluetooth and Wi-Fi when not in use.
