Data missing - Ipaq model HP5555 - did not do hard reset
Removed Ipaq from charge stand last night almost fully charged, backup battery at 100%, put in Ipaq carry case. Took out of case this morning. Orange light next to on/off switch displayed steady orange and all memory missing.
Plugged into charge stand but had to do soft reset to restart. Unknown if backup battery was dead or not.
How can data be retrieved? If not easily, recommend data recovery service we can have recover data.
Data not fully backed up elsewhere.

Re: Data missing - Ipaq model HP5555 - did not do hard...
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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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
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.
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.
That's a very odd scenario. Have you tried putting it on the cradle without the battery? One possibility is that it was an incorrect battery that you put into it and it somehow fried the PDA. That's however very unlikely. Have you tried putting your old battery in it?
