Question about HP iPAQ RX3715 Pocket PC

1 Answer

Battery Problem It seems that my iPAQ ran out of battery/charge and turned off. When I put it back into the cradle to charge it, it still wouldn't turn back on. Does it need to wait until its fully charged to turn back on, or do I have a bigger problem? Thank you!

Re: Battery Problem

Unfortunately, I think you have a bigger problem.

Ideas:

1. In the interest of not costing you extra money, wait a few days to see if anyone has any last-ditch ideas.

2. Your battery is probably completely dead. Try purchasing a new one (Amazon.com is good).

DO NOT THROW AWAY THE OLD BATTERY!!! If the new battery still does not work, the old one has probably been shorted by the charger, but it might not have been, and you will now have two working batteries.

3. If that doesn't work, then like I said, you probably have a short in your charger. Refer to

For the solution.


You can try these solutions in either order, but this is the order i suggest.

Happy fixing!

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.

Compaq Ipaq not Charging


As I understand it, the basic cradle that comes with the Compaq Ipaq 3870 does not charge. If I were you, I'd either seek out a charging cradle or google the instructions for modifying your cradle to charge. Good luck...

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.)

Cannot get past opening screen or turn off unit. Unit seems frozen


Hi,

Did you try to flash the BIOS/firmware of your device?

1.) Go to the Master Index of BIOS, FIRMWARE, & DRIVER Updates,
2.) Select the appropriate hyperlink for your model. (in your case it's here http://mobilitytoday.com/forum/showthread.php?t=4846)
3.) Download the most recent BIOS version SoftPAQ (SP) for your Model of iPAQ.
4.) Press the POWER + iTASK + CONTACTS + RESET buttons at the same time so as to enter the FLASH Mode
5.) Make sure your USB connection to the Cradle is hooked-up.
6.) Place your iPAQ in the USB Cradle.
7.) Stop the MS ActiveSync session on your HOST PC: CTRL-ALT-DELETE > TASK MANAGER > PROCESSES.
8.) Hilight WESCOMM.EXE and select "End Process" button.
9.) Run the file you downloaded from HP in step 3.
10.) The iPAQ should now begin Flashing the iPAQ's ROM BIOS

I got the same problem. I even tried to plug the battery to the second battery charging slot, still couldn't get it back to life. But the Ipaq screen lights on with progress bar progress for about 5 seconds, then dead again. I even doubted the battery was toasted.
I gave it a final shot:
1. Remove the battery, and then put it back.
2. While the screen lights on, within 2 seconds, cold reset the unit by press the hole with stylus and push the power button at top in the same time.
In my case, the progress bar will keep going until I see the tap screen instruction and everything back to normal. But it reminds me that the removable battery is totally discharged. So I put it in cradle and I am able to synch it with my PC. Everything seems o.k. while it sits in the cradle, except the charging light won't turn red.
When I remove it from the cradle, it still lights on, battery shows 99% which is healthy. but when I turned it off, it won't start anymore. I have to repeat the above steps to revive it. Sometimes I have to remove the battery and wait for a while and then put it back, so that the screen can light on to give me chance to cold reset.
Conclusion: Maybe need a new battery. I will check Ebay to get one.
Please post if you have other solutions.

Ipaq unresponsive


That's a very odd scenario. Have you tried putting it on the cradle without the battery? One possibility is that it was an incorrect battery that you put into it and it somehow fried the PDA. That's however very unlikely. Have you tried putting your old battery in it?
