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
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.
I will attempt to answer both questions and give some insite.
1st- No, the charger does not recharge the backup battery. The battery is the same kind of battery as you would have in a watch which at this time are not rechargable, but that would be a great idea.
The way it works is that when the main battery is charged the X5 uses that as its energy source. Only when the unit is off and or the main battery is depleated does the back-up battery kick in. Hence the name (back-up battery).
As for a solution to your problem. It sounds to me like you have a problem with your primary battery. I don't believe that it has much time left or it may just be a corrosion problem. I would try clening the battery contact point on the battery as well as on the X5 with some alcohol and a q-tip. I would also check the contacts where the back-up battery is. I have worked on watches before and their batteries will sometime cause some corroding.
are you checking your adapter. i had the same problem with my casseopeia e115. i searched and searched for the battery which even casio doesn't offer anymore. i bought a battery pack which works great w 4 AA batteries but it's bulky and you lose data when you turn off the batteries. i finally went on to discover that my charger/adapter that plugs into the e115 and the serial cradle was scorched by a lightening strike and it was not charging and eventually the batteries DIED!!! I took the adapter to an electronics repair store and for $15.00 they rewired the adapter and it works!!!! it charged the batteries and worked fine.(altho i have to visit them again because i think one of the new wires is bent and i have to position it perfectly to keep charging.) BTW: any one looking for a new casio battery jk210lt...i have a couple to sell! ;-)
hope this helps
You might hook your charger up to your battery and check the voltage that you are getting when it is fully charged. It may be that the charger is bad.
Your voltage when fully charged with the battery on it should be a little over the rated voltage of the battery.
Just a thought. Be sure you are using the correct poweradapter/charger also.

Blinking amber light means the battery is not fully recharged. Once it is charged, press the power button. If the the device still does not turn on take out the main battery and the backup battery. Put the main battery in first, then the backup battery and put the battery switch in the lock position. Press the power button and you should see initializing memory..., then starting..., then it will ask you to set up the device.
