My HTC p3300 battery not gettin charged. It works on direct power for some time and get automatically shutdown after some time..indicating no charge. Keeps shutting down often.

I too have been experiencing problems. Replaced the battery but it happened again. The battery says it is at almost 100% capacity however several times in the day, when I go to turn it on it doesn't respond. I end up taking the battery out and then have to connect it to a charger (USB) so that the charging light blinks red once and then turns off. I can then put in the battery again and it will start up again. If I don't connect it to the charger cable to drain (get the red light to flash once), and try just putting back in the battery, I've noticed that the screen has a faint glow as though it was on but the screen is completely blank. I'm starting to think that there must be a short circuit somewhere because I'm going to assume that the new battery is good.

Wont charge/hold a charge

That definitely is a battery issue. The battery is either Low Soc or it is a failed battery. Most batteries on PDA's usually fail within a year because of the immense amount of use the phone has and the majority of the time the batteries are smaller in a PDA. Take your battery to a service center if one is in your area or call your carrier and inquire about the warranty on batteries (usually 1-year).

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.

Ipaq H3835 PDA - won't hold charge??

If you purchase a new battery, they usually come with directions and special tools to change the battery. I had the same issue with 2 of mine when I got them at a used electronics store. IF it is the battery that is not working, then replacing it is easy, and you can get a replacement at your local Battery-Plus store.

In my case, one was fixed by a new battery, the other was not, and I actually had to press pretty hard in the cradle to get the second one to work. It never worked out of the cradle, so I gave that one to a neighbor kid to tear apart and see if he could get it working. (I got them for $15, so no big loss.)

Battery won't charge after being replaced

The charger might be bad. Or then the pdas connector is bad, or the motherboard is damaged.

to find out is your charger working you could use a tester to test it or another pda.

If you could get some power into the pda you could use the bootloader to test the device. Its been years since I had my 3850.

Il have to find instructions on how to get to the bootloader but test the other things first.

Drop a comment.

Red Light!

Hi xx

It sure does sound like a battery. If it is more than 12 months old, and regularly charged(daily) , then it will need replacement.

Ipaq 4155 wont turn on, dont charge, dont anything, is totally death


I had some similar experiences with these ipaq's when I was working in a specialised service center. I'll try to give some help or tips through the internet, altrough if i could have seen or diagnosticate these pda's myself it would have been more easier. First of all these problems have 2 main causes. Most of the pda's comply with one of them, it is very rare that a pda will develop this problem by having both causes.
The first cause is the hardware one. A component called the main voltage convertor is broken. It's a small chip that uses the voltage given by the main battery to convert it's value to various tensions required by some of the components on the pda's main board. If some sub-parts of this chip fails to work, the result will appear as the problem you face, In this case there isn't much to do. Most service centers will replace the whole mainboard because that particular chip is very hard to find as a replacement and difficult to desolder from the board.
The second cause could be a major firmware / ROM memory corruption. These things can happen out from nowhere. In my time working for service centers I've tried to isolate a pattern for this problem but without much succes. However it seems that most of these problem tend to appear durring charging cicles due to power spikes or drops on the main AC voltage supplied to the charger. This is only a supposition, I'm not sure yet on this cause. What to do here? Well this problems are fixable but first of all you must be sure that this is a software problem, not a hardware one. So let's diagnosticate some things.
Try to charge the pda. Ignore any lights or beeps or whatever your pda is showing on the screen. As long as the charger is connected the charging process is based on the most primary charging circuits on the pda's motherboard. If the pda is not charging or cannot hold any charge (when you unplug it the screen fades away or it simply doesn't do anything else) maybe that circuit is broken (this is a a sign of serious hardware problems ) or maybe the battery is to old/weak. Batteries don't die out of nowhere, if you remember your pda to work and have some 2-3 hours of standby time it's imposible that now, suddently the battery has drained out so much that even if charged it can't hold out at least 30 min.
So we will assume that you charged the pda for at least 2-3 hours and you see some sign that the battery is working. The next step is crucial. TRY TO PUT THE PDA IN BOOTLOADER MODE. You will achieve this by pressing (and keep them pressed!) the following buttons : power, the far left and right buttons near the control pad (joystick or whatever some people call it) and reset button. You may need another person to help you press these buttons. the order should be the following (first power, then the 2 keys, then reset button for as long as it takes to enter bootloader mode). YOU SHOULD SEE A WHITE SCREEN WITH THE HP LOGO.

If your pda fails to do that, there is nothing more you can do to restore it in a DIY fashion. Probably the bootloader is corrupted or you have a hardware fault. Only a specialised HP service center can help you now. In most cases this will end up with a motherboard replacement.
If your pda does that, then there is a chance to fix it. We will need to probe the bootloader for direct data acces. This is needed for having the ROM memory (and operating system) rewritten. A small program called Mtty will be required to access the bootloader via an usb link.

Please make this tests first and then reply with your results. If anyone of you is in situation #2 there may be a chance.

The Screen is back and it won't charge

Hello, it isn't that simple as a broken charger. Try the following thing. Connect battery to the PDA, check that the battery LID is connected FIRMLY to the body (there is a contact there that woun't allow the PDA to start if the lid isn't connected properly, you may want to check it too, look carefully for a small black thing and check that it can be pressed). Then connect the pda for half hour to the charger, even if no light or amber led is flashing. Then make a master reset as showed here and connect the PDA to a usb sync cable with your computer. Press simultaneous the soft reset and the power button, then press only the soft reset button. The PDA should start. If not, there is a problem with a DC converter component on the mainboard or the connector I was talking about before. Even if the charger is broken, your PDA should power on from USB cable. Good luck, feel free to ask further questions and always remember to rate replies received from this site :)
