Re: how to change the backup battery of ipaq 1940?


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.

You would have to backup your iPAQ probably through your computer instead of on the handheld. Otherwise there is no way to save your applications.

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

HP-iPaq 2215 battery replacement

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.

Low Battery DATA Lose - HP iPAQ Model h5450 Packet PC

The h5450 comes with what HP calls a backup battery. It is built into the device and not accessible by the user. However, the backup battery has only enough juice to power the Pocket PC for a few minutes while you change main batteries. Don't expect it to keep your RAM data alive if the main battery runs out.

Do I need to select iPAQ Backup Options each time before Backup or Restore?

Once Options are selected, they will be remembered (unless hard reset or total loss of battery power), so there is no need to select Options each time iPAQ Backup is used. In the case of hard reset or complete loss of Battery power, the options setting will require resetting.

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 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.
