HP iPAQ HW6515 Troubleshooting

iPAQ will not turn on

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

Stuck power button

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.

Uncharged battery

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.

Dead battery

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.

Bad motherboard

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.

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.
