Backup battery problem

On the motherboard, at the bottom near the charging port. You will have to remove the motherboard completely to access it. Here is a good tutorial with pictures and all the information you need.

its in the back of device a slight curved flap is given just lift that flap and its there.

Replace the battery with a new one and it should behave afterwards.

CR2032 battery. Backup your information first.

i believe if you are a bit of a hands on type of person you should be able to do this yourself.
but not without researching !

read this page, should tell you everything you need to know, from the perspective of someone who had to do the same changing of the CMOS battery.

DISCLAIMER : I take no responsibility for any damage you may cause to your Axim. The parts and proecedures described in this guide refelct my own experience with my own Backup Battery (BuB) in my girlfriend's Axim X3. Your mileage, parts, anbd experience may vary.

Tools needed for successful BuB replacement:
1. fine tip jeweler's screwdrivers (helpful if you slightly magnetize the tip)
2. Varta V20HR rechargeable NiMH battery
3. electrically conductive silver epoxy
4. strong needlenose pliers
5. electrical tape or heatshrink (razor blade or scissors to cut to shape)

But here it is step-by-step:

1. Pop little rubber caps from 4 corners of back covers. Disassemble Axim X3 with small jeweler's phillips head screqwdriver. Be sure to plave all parts in a plastic bag or other container (4 scres rear cover, 2 screws near port). Disconnect the ribbon connector towards the bottom of the PCB and the speaker wire (also on the lower portion of the PCB). Backup battery should be the green covered circular item under the pcb).

2. Locate backup battery, Cut away BuB cover, & CAREFULLY use strong needlenose pliers to grip and "roll" the leads off of BuB.Be very careful with the leads.

3. Mix dime sized batch of silver conductive epoxy (do NOT hot solder this battery, heat will lead to BuB damage and destroy lead connection to wire).

4. Apply epoxy to both sides (not too much)and afix respective leads to respective side (red lead goes to +, black lead goes to -). Secure connections with some type of clamp (I used a binder style paper clip, but a wooden close pin or something else that will hold the leads to the BuB while the epoxy cures (Mine took 24 hours to cure).

5. Recover new BuB with protective covering (I use electrical tape cut to the shape of the BuB. Covering WILL have to be form fitting to fit back into Axim BuB "slot".

6. Reassemble and charge Axim and charge.

it could be a short in the cable to the battery

hi thanks for using fixya!

You have to bring your Dell Axim X5 PPC to a service center, to check further the back up battery if needs to change it.

If you need further assistance, let me know.

--This is a suggestion. I can not be certain given I have not worked on this device. --

Sounds like the backup battery is dead and needs to be replaced.

Researched The battery, and it is a standard flat-cell available at Radio Shack.

Taking the device apart will void the warranty.

The device is assembled in a standard click-tab and possibly some small hidden screws.

A plastic screw-driver or non-marring wedge tool is best.

Simple work your way around its edges until a gap forms and gently feel towards a portion that will not separate. Get a tool in there and gently pry away from the device to disengage the clips, rinse and repeat.

Upon removing all the tabs, remove the back panel slowly to assure that there are no wires connected to the panel itself, you should see the battery.

My Axim X30 would not turn on using battery power but would turn on when connected through charger adapter.
Solution:
1. Connect AC adapter directly to the charger adapter and then to the Axim X30 and to the electrical outlet.
2. Charge battery until power button is solid green.
3. Press the power button to power on.
4. Remove cable from cable connector leaving the cable connector connected to the Axim X30. The Axim X30 will remain powered on.
5. Turn the Axim X30 off.
6. Turned the Axim X30 on using battery power.
7. Remove cable connector from Axim X30.

step 10 is actually the lead to the backup battery. Follow the wires to find the battery.

Hope it helps.
