DOCUMENT NUMBER: MH020124_CW02 REVISION: 3
Upon powering the iPAQ Pocket PC, the backlight may fail to illuminate
RELEASE DATE: June 2002
When applying power to the iPAQ H3800 Series Pocket PC, the backlight may fail to illuminate. Holding down the power button to engage the backlight may not provide resolution.
This issue is typically experienced after the unit has been off for several hours. The backlight may function correctly after a normal reset or an adjustment to the backlight settings, but may fail again if the unit is powered off for some time.
iPAQ H3800 Series Pocket PC, models: H3835, H3850, H3870 & H3875 with Serial Number 4G25DW33Axxx and earlier.

Customers should take appropriate troubleshooting steps to ensure this is a hardware failure and not the result of incorrect settings.
Verify the backlight has not been inadvertently turned off. When the power button is depressed for more than 3 seconds the backlight will cycle on or off.
Verify the backlight settings are not set to ‘Automatic’ and the iPAQ is not under bright lighting conditions that will cause the backlight not to illuminate.
Customers that experience a hardware issue should have their unit submitted for warranty service.
