The backup battery is no longer charging. It is not obvious how to replace it. I see replacement batteries are available but how do I go about doing the replacement?

This PDA is relatively difficult to take apart. I've done it myself and it was very difficult. It is not recommended by any means because you can seriously mess up your ipaq by taking it apart. On the site I gave you after you buy and receive the replacement backup battery, if you do it yourself, will give you a site to get instructions from. You can also send it in to have it done professionally.

Hello Paul,
Yes the battery can be replaced but this will require you to dissasemble the pda. The problem you face is a clear sign that this battery has failed. There has always been a problem with hp's battery measurement algorithm regarding that secondary backup battery. Altrough it is empty or even if you remove it, the program will still display a full bar. In order to change this battery you will need to remove the screws from the back of your unit. The casing will come off pretty easy. The back-up cell is a small coin like battery most probably wrapped in a green plastic shel. you should find a similar battery and connect the pins from the old one to the new. The battery size is not critical as long as you can make it to fit in the space inside. Try, however, not to use a very small battery because it will drain much faster then larger ones. Carefull when observing polarity.
If you need more informations please reply.
Bogdan.

It sounds like (in all 3 cases) a new backup battery is required.while these are cheap to obtain, they are not always that easy to replace. I can provide detial on how to change them if required.
email [email protected], and i'll send a picture guide to you.

Hi, Jim--
When you take the battery out of an IPAQ you're performing a hard reset. I've got 4 different IPAQs and it does the same thing on all of them.
My solution was to back the IPAQ up using the internal backup program (back up to IPAQ storage) and then replace the battery, then restore the last backup.
Saved me a heck of a lot of time. It's been hard to remember to back up everytime I add a program or change data majorly, but it's probably the best thing to do.
