You feel like you’ve tried everything, but your iPAQ will not turn on.

If your iPAQ will not turn on, the power button may simply be stuck. Try holding down the power button in the upper-right corner for at least four seconds.

If the iPAQ does not turn on even after holding down the power button, your battery may not be charged. Check that the AC adapter is completely plugged into the wall outlet and connected correctly to the phone. If it is, either a light will indicate that it is charging or it will say so on the screen.

If there is no response when plugged in the AC adapter, your battery may be broken. To install a new battery, follow this repair guide.

After replacing the battery, the iPAQ should turn on. If it is still not responding, you may have a faulty motherboard. To install a new motherboard, follow this repair guide.

You’ve pressed the keys numerous times, but the keys do not register or are sticky.

If your keys stick when you press them, try cleaning around the keys using a cloth or Q-tip dampened with multipurpose cleaner, such as Windex, or rubbing alcohol.

If this doesn’t work, you could try using aerosol dusters to spray between the keys.

If cleaning your keyboard does not work, it may be broken beyond repair and will need to be replaced. Please follow this guide to install a new keyboard.

Your phone displays a message saying it does not detect a SIM card.

If your phone does not detect a SIM card, one may not be currently installed in your phone.

To fix this problem, install your SIM card by following this guide.

If you have a SIM card installed and the iPAQ still does not recognize it, it is possible that your SIM card is installed backwards or upside down, analogous to a vending machine rejecting your incorrectly-placed dollar bills.

To correctly orient the SIM card, follow this guide.

You tried taking a picture in a dark room, but the flash did not work.

If the flash does not go off when taking a picture, check to make sure that the flash option is enabled in the phone’s “settings”.

If the flash is enabled in settings and it still does not work, the light bulb that generates the flash may be broken. To install a new LED bulb, follow this guide.

Every time you turn on your phone, the screen freezes.
