IPAQ 3700 Series - Battery not holding charge

We have several of this devices and seems like on many of them the battery of the devices (iPAQ 3765) will stop working very soon. Are there replacement batteries available? Can they be ordered? If not, how can this issue be fixed without having to use external power supplies? thank you.

Re: iPAQ 3700 Series - Battery not holding charge

In this model of ipaq the battery come inbuilt which means it is not enduser replaceable so cannot place an order to the battery so call HP and send the unit in for service. All the best :-)

Data missing - Ipaq model HP5555 - did not do hard reset


Hello,

I'm sorry but the HP Ipaq 55xx series store data on a volatile ram based memory. Unlike a nand flash (like usb sticks, memory cards etc) this memory will hold data only as long as it's powered on. If your main battery gets empty you should still be able to retain your files for some 10-20hrs with the backup battery (if it's ok itself and not depleted). After this time the power to the ram memory is cut off and all data is lost.
The problem you face is somewhat related to that backup battery, as it appears it's unable to do it's job and maintain the power to the ram memory at least some 10 hrs. You should have that battery replaced.

There is no way to recover the data from the ram memory as it is stored as an electric charge over some memory cells in the ram chips. When there is no power, these charges dissipate and the pattern is lost.

I'm sorry for having to give the bad news.
Bogdan

I had the same problem with my iPAQ H3800. I bought a replacement battery on eBay for £7.49 and now it's fine.

This IPAQ will not support 3rd party battery manufacturers. Ensure you are using an original HP battery. You usually can use the battery one time--but when the charge runs out, so does your luck.

Most of the time you will get an on-screen warning that the battery will not be able to charge when you use a 3rd party battery. If you are using an original, you might need a new battery--they do wear out after time--too-old batteries no longer hold a charge.

Cannot power on...


How to correct iPAQ 5450, 5455, 5550, 5555 battery charging problems / dead unit syndrome.

The iPAQ 54xx or 55xx will not power on if the batteries charge is lower than 3.2 Volts, if your battery charge falls below the 3.2 volts level your unit will not turn on, you need to plug the iPAQ into a cradle or AC charge adaptor. Note the charging light on the iPAQ will not flash at all (normally flashes orange) until the battery charge has reached a minimum charge level of 3.2 volts. You then need to perform a normal reset, then the unit should switch on normally.

HP Procedure is as follows:

To charge and reset the iPAQ Pocket PC h5400:

i) Connect the iPAQ Pocket PC h5400 to an A/C power supply.
ii) Charge the battery to the minimum level of 3.2 Volts. This will take 5 to 30 minutes depending on the current charge level.
iii) Perform a normal reset.
iv) Power on the iPAQ Pocket PC h5400

It is recommended that you keep the iPAQ Pocket PC connected to the Universal Cradle or Cable when it is not in use.

Most iPaqs use a small AC Adapter This model will still need an AC Adapter, because it does not draw any current from USB to charge.
