Solution (Continued)
In Backlight Settings, increase the amount of time the
backlight stays on if not in use. From the Start menu, tap
Settings > System tab > Backlight icon.
In this event, the HP iPAQ uses the remaining power
available in the battery, but the battery will not charge and
the charging LED will not blink. It is recommended that you
back up information stored on your HP iPAQ and purchase
an HP authorized battery.
The HP iPAQ goes into a suspend mode and battery
charging is prohibited. The device will not operate until the
battery is within the acceptable temperature range (32° to
104° F). Remove the HP iPAQ from extreme hot or cold
environmental conditions.
1. Back up your information to a memory card or external
source for safekeeping.
2. Disconnect all external devices.
3. Pack your HP iPAQ and any external devices in
protective packaging as requested by Customer
Support. Include any additional documentation or items
as instructed by Customer Support.
