Rx3715 battery power trouble

I'm having these issues with my Ipaq rx3715: 1. I turned off pda and the next day it wouldn't turn on (battery was at least at 60% for sure when I turned it off). When I connected the power cable, I was able to turn it on. 2. I let pda turn off on its own after 3 minutes (while using battery), then couldn't turn it on until I removed and placed back the battery in the back (still not connected to power cable). Any help appreciated.

Re: rx3715 battery power trouble

Did you check if the PDA was hot? My battery was totally dead one day when I picked my 3715 up, just to found out it was blistering hot (was turned off) and even the backup battery was empty. Running fine now after hardresetting it, but still...

My ipaq rx3715 shuts down after plugging into its cradle. It gets the screen alignment and just goes blank.


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. False contact on such back switch.

You need to find exactly where is located the switch that senses the battery cover lid.

It's located at the right/bottom side thru the battery bay. Check that there is not dirty or dust accumulated, causing that is sticky such area, which prevents such switch to work properly.

If you find nothing obvious, you can use small pieces of transparent tape (or masking tape) and put them on the internal side of the cover lid that is in contact with the switch (you have to locate first such area), put the battery and coverd lid again, and try to power it on. You can add a 2nd or 3rd layer of tape to depress such switch.

3. Broken cover lid. Check that is not broken in any part or corne rof it. If it's so, then replace it.

4. Defective switch.

Unfortunately is necessary to open the PDA and check with a continuity (or ohm meter) the performance of such swicth, which is easy but usually a technician does it.


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

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.

ALING DISPLAY CYCLICAL PROBLEM


If I understand correctly your problem, the touch screen of your PDA is not working.

Well, this is a common IPAQ failure. When happens, the only options to repair it are:

1. Soft reset of the PDA. If still does not work, then go to next step.

2. Replace the top digitizer glass.

It requires a very skillful person to do it. If you have not experience with fixing electronic devices, then I do suggest you to send it to repair.

Besides that is necessary to open it, you will require a soldering iron, and desolder the digitizer part and remove it from the LCD screen, which if is not done properly with the right tools, it's easy to damage the LCD screen assembly.

Also, if it's not opened right, is possible to damage permanently the mainboard if is bent or warped.

Also, even though there are a lot of cheap digitizer replacement parts on-line (mainly from China), they have a compatibility issue that prevents to use them in the RX3715 (or RX3115) PDAs.

I have nothing against Chinese manufactured parts, but after buy around 10 digitizers in the last couple of years for different Ipaq PDAs, I found out that only 3 worked fine, so I know what I am talking about.

Does not turn on


There are some known issues with the included charging equipment. Personally, I ordered a relatively inexpensive charger from Amazon.com that works wonderfully. All you really need is a device that turns a standard wall plug into a USB charger. You can then plug your base that the ipaq stands on into that and it should begin charging. The old battery is probably dead (mine was), but try to charge it anyway.

Note: The actual cord that came with my charger DID NOT WORK. It is sitting in a box somewhere, and if its the same thing I had (it probably is), then you just need the wall-to-USB converter.


This is what I bought:

http://www.amazon.com/iPAQ-rx3715-Sync-Charge-Cable/dp/B000DT8F0A/ref=sr_1_4?ie=UTF8&s=electronics&qid=1204335733&sr=8-4


It is only $10. Again, the cord didnt work for me. Maybe it will for you, but if you manage to find just that converter for less money, more power to you!

Drained batteries, not powering up, next step?


For me I prefer charging the iPAQ using the usual cable, not the USB as I had some troubles with that It makes the battery drain faster. So Use a usual charging transformer.

Ipaq totally dead after leaving it in my car for two weeks, temperature down to -6C


Its possible (but not likely) that when you took it into a warm room condensation built up inside it. Try removing the battery, memory cards and letting it sit in a warm, dry environment for a few days and try again. If nothing changes I suspect that a component has failed, but -6F is still within the operational range of commercial electronics. If your device is still in warranty then I would call HP up and ask for a warranty replacement. Let us know if you have any other questions and please don't forget to rate this posting.

Rx3715 several problems


If you have only flashed the English ROM, not any other language ROMs, read the following paragraphs. If you have flashed other language ROMs but not the German one try flashing the German one instead, there is something about it that clears the ppc out better. If you have flashed the German one, do not read on, as it will be an insult to your intelligence.

Most problems can be fixed with a ROM correction. Unfortunately, this is unachievable by simple re-flashing the English ROM. Certain other versions of the ROM (usually German is used) contain different enough sets of code (possibly different firmware?) to force the ppc to truly reset, unlike what happens when simply flashing the US ROM or changing to ROMS that use similar enough coding. Try flashing the German ROM and THEN reverting to the English. This tends to solve most any major iPaq issue.

Help with IPAQ RX3715


(1) LAST USED APPLICATION Enable password protection. Start>Settings>Password (2) SENSITIVITY / PRIVACY Choosing "Private" prevents the appointment from appearing on your Today screen. I figured this out by creating two appointments for today and making one normal and one private. The private appointment is still viewable in the Calendar application, so if you want to prevent others from being able to access this, enable password protection. (3) TODAY MENU There is no way to do this using the software that came with the iPAQ. However, there may be third-party software that would accomplish it. I did a quick search that turned up nothing, but you might be able to find something. Try handango.com or pocketgear.com.
