Question about HP iPAQ HX4700 Pocket PC

AC charging issue

Hi I have recently purchased a IPAQ HX4700. The battery won't charge via the AC adapter cable. It only charges through USB. So far I have been using it whilst attached to my PC through a cradle and enabling the USB charging option. Have any of you come across a similar issue? Would appreciate any feedback. Many Thanks.

Why wont my nookhd wont charge


If it\'s only two months old it may have a defective charging cable or adapter. If it\'s a new purchase and you can return it. To check to see if it might be the adapter and not the charging cable you have a few cheap ways to test this out.



General charging recommendations.



If you get power leave it on charge at least 3+ hours. This is the minimum time required if the battery is totally drained. If the Nook turns itself on during this process manually turn it off. The battery charges faster and more deeply if it\'s truely powered down. Charging more than 3 hours won\'t hurt it. In fact some manufacturers claim leaving thier products on charge for an additional hour after the charging light glows green is good as it leaves a slightly deeper charge on the battery. Also I believe leaving it alone for that hour allows it to cool the battery. Most manufacturers also recommend tottaly draining the battery at least once a month and then fully recharging it 1+ hours after charging light is green. They claim this helps the battery maintain a healthy charge and extends the battery life. Simply disconnect any charging cables, turn the unit on and just let it set. Don\'t touch it peroid just leave it alone until it turns off because the battery is totally drained. Then just plug it in and leave it. Only if the unit automatically turns itself on do you manually turn it back off.



Well that\'s about in in keeping the battery life and charge at its maximum.



If your AC power adapter has gone south there are only three ways to get around this. 1. Purchase a generic AC to USB adapter. 2. Purchase a genetic DC to USB adapter. Most of these can be cheaply purchased at most drug stores ect.. these days. You can even get DC to USB ones at dollar stores such as Dollar Tree. Good way to maintain your battery if your AC one goes south or you lose house current.



One other way to charge your battery is to plug the USB cable into your computer. Some manufacturers don\'t recommend this as this more often than not doesn\'t fully tank up your battery.



You can also get replacement charging cables at the same place you got the adapters. Places such as Walgreens, or CVS often have these at around five dollars a pop.

My Kindle Fire will not start


If you last charged it with the computer USB port, try charging with the supplied AC adapter instead. If you last charged with the computer USB port, try charging with the AC adapter this time. This will help isolate a bad AC adapter / power cord or USB cable / USB port.

It is important to note that if you are charging your Kindle via USB port on a computer, when many computer enters "sleep mode" the USB power is shut off at this time too. Charging is effectively halted - even though still connected. You should only expect to charge while the computer is active or when using the AC adapter.

You can also purchase an aftermarket DC charger. These are small plugs that are inserted into your auto's port or cigar lighter. They provide 1 or 2 USB connectors to plug in a USB cable. These devices are suitable to supply / charge just about any devices that uses a computer's USB port to power / charge a device. They cost anywhere from $5 and up and look something like this:

If there are no power points in your vehicle, you might have to purchase a battery-operated powerpack and plug the GPS into that via a USB/AC adapter.

Hp ipaq seems dead


Without know exactly what already you tried to powered it on, I can only especulate on all the possible reasons, so let go one by one throuh them and their possible solutions:

1. The RX3000 Ipaq family has a known mechanical issue on the switch that senses when the back cover lid is properly closed.

When the switch is nor properly depressed, the PDA won't charge the battery if plugged on the cradle or to the USB sync cable, or won't turn on.

Remove the back cover lid and the battery, put them back again. Check the cover lid is placed flush and that there is not any gap between the cover and the PDA body.

Try again in power it on and/or charge the battery, confirming the orange LED light is turning on.

2. Either the cradle/USB sync cable or the AC wall adapter are defective.

The PDA won't power on if the battery is not charged to the minimum voltage for it. If the AC wall adapter or the cable/Cradle are defective, won't power on.

Put to charge the battery and confirm the orange LED light is turning on. If so, the you can discard that the cradle/USB cable or AC wall adapter are defective.

It the orange LED light won't turn on, it may be either one of these three parts that are defective, or that the back cover lid is not properly closed.

3. The battery dried out. If the battery is defective or won't accept charge, the pda won't power on.

To discard a defective battery, put the PDA to charge it, and it will power on when plugged to the USB cable or to the charger, and check in the settings screen, on the power icon, if the battery is charging.

If the back cover lid is properly placed, and the PDA won't power on when plugged to the USB cable or AC wall adapter, then the battery is not the problem.

4. Discarding that the battery or the USB cable or cradle or the back cover lid are the problem for this problem, the only option that is left is that the main board is defective.

Such failure on the mainboard could be caused for several reasons (moisture or humidity or water damage, or a electronic component that is worn out, or a integrated circuit that is shorted, etc) but it can be only verified and confirmed by an electronics technician.

You have the option of send it to be repaired, or try it yourself, which will require to buy a PDA with working mainboard (or the mainboard alone) and swap the parts. It requires a minimum of technical skills to do it.

If you are not using the original chargers it could be the type of charging cable. Not all cables that fit will charge the device correctly.

My H5450 won't charge!


When you charge up your iPaq, do you use the cradle, or do you use the AC-adapter with the little iPaq power converter that came with the iPaq? Try both, and see if it charges up your pda. Try and borrow an iPaq car-charger and see if it charges up that way (the ones that do not need the iPaq power converter). If you are lucky enough to power up the iPaq even for 2 minutes, enable USB fast charging in the SETTING -> BATTERY. Your USB-data-cable or cradle will then be able to charge it up that way...
