From the Start menu, tap Settings > System tab > Power icon
> USB Charging tab.
2. Select Use USB Charging.
For faster charging, turn off all wireless activity and place your HP iPAQ
in standby mode by turning the unit off.
NOTE: The LED charging indicator does not light when the HP iPAQ is
turned on and being charged with a USB connection.
