So you bought a Compaq iPAQ H3800 and the backlit screen sometimes doesn't work? Don't fret, you didn't break it, you're not alone.
Compaq is on the case: in a customer advisory, the company says: "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."
Yes, but why does it do this, and how can it be resolved? Compaq doesn't have the answer to either question. But rest assured, it will issue another advisory as soon as it knows what to do. Then it will "advise you when it is appropriate to submit your iPAQ Pocket PC for a service event". What is a service event, anyone? ®
