SOURCE: BT Problem Battery/Power Problem

In my opinion it is always very risky to buy some second hand unit because you can not be sure if every hardware component works properly. The best solution for you is to contact service partner and let them check the PDA. It is also possible that power supply electronic has some malfunction

It is estimated that you will have a few days to recharge your battery if the battery is exhausted.

SOURCE: Treo 680 charging light flashes red when disconnected from charger

Have you activated phone yet? When phone is activated and in service it flashes green. It's hard to believe it would flash green without a SIM card, as there is no service...unless AT&T is providing emergency service only and you're getting a flashing green which means you're in range of their towers.

SOURCE: My T-Mobile MDA won't turn on or take a charge, battery was low

I had the same problem, but got the idea to "jump start" the battery from Googling the problem. At night, I had turned off my MDA to charge the battery and then in the morning, couldn't revive it. I removed the battery from my MDA, and determined which battery terminal was positive (far end of one side) and negative (far end of the other side) by using a multi-meter. BTW: Battery was still @ 3.5V (okay…battery was still alive, if just barely). Then, I found a 5V DC charger (5W Max output = ~1A) from my bluetooth headset. I used one wire (CAT5E) and connected it to the negative side of the adapter (outer sleeve - again, verified by multi-meter) and another wire to connect to the positive tip of the adapter. I had to strip about 1/2-inch of the insulation off of the wire on the DC adapter side, and about 1/8-inch of the wire on the battery side. Plugged in the 5V DC charger and then I touched the negative wire to the negative battery terminal and held it there, while I touched the positive wire to the positive battery terminal for about 30-45 seconds. Put the battery back in the MDA, started it up, and now it's charging on the regular MDA AC Charger that came with the phone. Problem solved.

Power light is blinking green and amber


my power light flashes green/ amber as soon as it is plugged in, with a dead battery. It seems to go to steady amber if the plug is tapped, but goes back to flashing. It will not hold a charge on a new battery.

Hi i plug unit with battery for charging no display lcd and no light indicator colored orange . I take out battery pack and charge then it produce light orange-red indicator of unit. I noticed charging...


Hi I solved the problem by taking off the battery for around 1 hour.

I attached the battery again.

And press hold switch around 10 seconds.

The unit booted and it proceeded to auto configure and auto installed program soft wares.

I realized that the unit is self shutting off.

Solution is go to setting.go to system.go to back light menu.
on backlight on external power .Be sure to uncheck turn off backlight if devise is not used for 1 minute.

Be sure to check turn on the back light when button is pressed or the screen is tapped.

press ok to activate the setting.

For maximized battery power and optimized power usage .go also to back light and go to brightness level.
Slide the battery and power to almost the 2ndlevel .

Hope this also will be applicable to other o2 xda iis configuration.

Best regards

If the light doesnt turn to orange after a few minutes on the charger then the problem hardware related. Try another battery if there is no change then there is fault in the device, and repairs are required.


also you can try

this:

1. Plug it in the Charger without the battery inside.

2. switch on the power.

3. Without removing the charger plug in the battery.

4. Light should turn orange.

5. Wait a moment or two then power it on.

that might get it to work.

I got the same problem. I even tried to plug the battery to the second battery charging slot, still couldn't get it back to life. But the Ipaq screen lights on with progress bar progress for about 5 seconds, then dead again. I even doubted the battery was toasted.
I gave it a final shot:
1. Remove the battery, and then put it back.
2. While the screen lights on, within 2 seconds, cold reset the unit by press the hole with stylus and push the power button at top in the same time.
In my case, the progress bar will keep going until I see the tap screen instruction and everything back to normal. But it reminds me that the removable battery is totally discharged. So I put it in cradle and I am able to synch it with my PC. Everything seems o.k. while it sits in the cradle, except the charging light won't turn red.
When I remove it from the cradle, it still lights on, battery shows 99% which is healthy. but when I turned it off, it won't start anymore. I have to repeat the above steps to revive it. Sometimes I have to remove the battery and wait for a while and then put it back, so that the screen can light on to give me chance to cold reset.
Conclusion: Maybe need a new battery. I will check Ebay to get one.
Please post if you have other solutions.

To be sure if its not the battery thats bad, connect it to the charger and charge for a while. Monitor the light indicator at the top right of the phone.It should start from red to green after its fully charged. then try to restart it by turning on the power button also at the top right of the phone.
If after these procedures the phone does not start up or it shows some temporal 3 seconds flash of power, you may need to get another battery. If a new battery does not start your phone,then its a power fault.It needs to be rapaired.
