The backup battery exists to protect your data when the main battery dies. It only has enough power to keep the internal memory 'alive' so you dont lose your files, settings etc.

When the backup battery dies it should be replaced as soon as possible, as the main battery will power the internal memory only while it has charge. Should the main battery die it would be like performing a hard reset.

How do I prevent loosing data when my battery discharges


Hi. Actually, on pocket pcs there's a backup battery onboard, but in your case maybe backup battery is dead. So you can have that changed or you can charge your PDA on regular basis. Hope this helps.

IPaq rx3115 working like PC not Pocket PC, need to plugin always


You need to purchase a new removable battery for your RX
The removable batts usually only last about a year (like cell phone batteries).
Although it is showing 100% charge, the battery is not storing enough power to run the ipaq

The rx series uses 2 batteries, one is the removable one u can see/access when u remove the back cover. The other batt is a small round batt which stores the basic info for your system (so you don't lose your data when u swap out the removable battery).

This small (backup) batt is similar to the cmos battery on a laptop or pc.
You cannot easily replace this, as the unit needs to be disassembled to access this batt.
If you are tech-y (and brave), the replacement button batteries are sold on ebay for $9-12

Normally, if your removable batt is bad, you could still use your unit plugged in, and could
remove from AC power without losing data. Not the case if your replaceable batt is exhausted.
When both batteries are bad, you lose everything when u remove unit from AC power.

My workaround without having to disassemble unit:
Purchase and fully charge new removable batt (They have huge capacity ones available for like $15 - better than the original !).
Load up all your programs & settings the way you like.
Perform full backup to SD card (& also on PC via active sync - to be safe)
Now the only time you should lose your data (like hard reset) is if you allow the battery
to completely drain, in which case you can restore your backup.
If you purchase 2 removable batts, you can easily swapout without losing data if you
use the usb charge cable & leave ipaq plugged in while you change battery

Hope this helps

Backup battery is not charging not visible.backup battery none


hi thanks for using fixya!

I recommed that you bring your Imate PDA to a service technician to check further the error. It is not a good sign, especially if there is a problem with the back up battery.

Regards!

1. Make sure you phone is fully charged. (At minimum 3/4 of bettery should be left)

2. Backup your contacts list and personal files to MMC memory card (if possible).

3. Switch-off your mobile phone.

4. Press and hold these three keys together

The backup battery not working


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.

Battery backup related


Most of your data (phone directory, calendar etc) is stored your pda's ram. If your LiON battery runs flat , the pda wont start up, your backup battery kicks in to preserve the data. If your NiMH battery runs flat, you will loose all data in the phone or the equivalent of a hard reset.

Data erased from iPAQ hx4700


If an ipaq loses power , then all data in RAM is lost. It's important to keep it charged. It's also important to do regular backups..... so there are two backup options - one is thru Activesync which will backup to your PC and one is the IPAQ's own backup program which will backup to the IPAQ FILE STORE (area in ROM) or a SD card. I do the Activesync backup every time I sync and then the IPAQ backup about once a week or immediately before a system change. Activesync backup ------------------------ Here is a guide which best explains it http://www.cewindows.net/faqs/activesync/backup.htm this guide suggests doing a full backup, but it's fine to do an incremental backup each sync - this means that only changes will be added to your backup and makes the whole process much quicker. IPAQ Backup ----------------- So under Programs is a program called IPAQ Backup. The default location is IPAQ FILE STORE which is an area in ROM and is not lost thru a power failure nor hard reset. You may also choos to backup to a SD card - a full backup will need roughly 20MB. So in this backup procedure, if you click on 'Browse' you can choose a SD card. A restore can then be performed from the IPAQ FILE STORE or SD card (depending on which location you chose) and so if you are away from your PC, this will be no problem. A restore this way , rather than thru Activesync is also much quicker, so if you have a choice go this route.
