XDA 2s Completely dead, how do I revive?

Please help me out, my O2 XDA 2s went completely useless. It started when I use the Wifi longer and sometimes never turned it off. I noticed that the battery (back) was always hot when I touch it. I am always having a problem of soft resetting and even hard restarting. But a week ago, it went completely dead. Since I have no time to check it, I simply left it.
Now, when I try to hard reset it (reset and power button), there was nothing on the screen (completely black) and the light are no longer blinking (BT light and GSM light??) As if the XDA is really DEAD. It has no response and it wont sync too. I have recharged the battery and changed it with a spare battery but the same thing happens. What I notice is that the back of the battery still gets hot.
Please help!! What am I suppose to do?

i-mate PDA2K completely dead, too
Hi, I had almost the very same problem:
I used a 3rd party charger to charge my i-mate PDA2K and all of a sudden the normal screen flashed to the boot screen and the device went dead: no BT/WiFi/GSM lights, black screen, not responding to soft reset or hard reset either. When I plugged in the charger or the cradle, the battery charging light came on.
I took out the battery and wiped the contacts with acetone, but that didn't help. All manners of resetting (power+camer+reset, power+record+reset) did not work.
Here's how I solved it:
put the PDA in its original cradle
waited several minutes
pressed the power button
The thing came back to life, as after a soft reset (nothing from the RAM was lost). I immediately went to the battery screen and it showed a 0% charge of the main battery and a 100% charge of the backup battery. The battery was never hot, though.
I suspect the connectors of the charger I used somehow shortcircuited or otherwise discharged the main battery. Any advice on a good charger cable for the i-mate PDA2K?

I have tried all rest type too as you have said. But it doesnt start or boot. The battery heats up though.
Any help? Please !!!!
Thanks

please help! DEAD BA! Any ideas...

I awoke this morning to find my BA (still plugged to the chrager) with no green light. it would not power on. I tired to remove and replace the battery, nothing. i tried soft reset and hard reset. when i put it in the cradle the light is red for a second, then goes off. I cant seem to get it to power on for anything? anyone have an idea?? please help! thank you

im glad no one wasted time responding. apparently the charger i was using drained the batteries. even though i got a red light when i set it in the cradle. after some time all is well. no data or settings were lost.

I think, You have some troubles with power converter in your BA.
It responds for conversion 5vdc->3,7vdc for battery charge and 3,7vdc->2,5vdc for pcb powering.
Best regards,

I think, board or rom error

BA turning off if removed from cradle and not turning on again

Hello guys,
I have a problem, i haven't used my VPAIII for 6 months, and some days ago i wanted to turn it on, and it didn't react, so i decided that battery is low, i connected my device to cradle, and wait for some hours. So the problem is then device in cradle it's ok i can switch it on and it works perfectly, but if i remove it from cradle it turns off imediately and i can't turn on it again without connecting to cradle chargement, also it doesnt react to usb connection as chargment. Battery is totaly new it was bought from ebay (expanded 3400 mAH). Interesting thing that if i connect to cradle, device turns on automaticall and 1 time blinks led in red and goes booting system with no led light, after i see Windows screen it starting show the same right led in orange always, i see charging battery meter in windows but battery didnt go more then 50%, and everytime i boot on i receive Backup battery Very Low notification no matter how much i was charging my battery.
So i'm afraid maybe it's internal backup battery failure, or my main battery didn't get chargement then it says that charging. Maybe someone of You guys have any usefull advices, what can be the problem? Also if it possible maybe somebody can give me alink or image to see there this backup battery soldered on scheme.
Thanks ppl!!!

It sounds like the main battery is bad.
Is the battery you picked up new, or new as of 6 months ago? If it's new-new, it is still possible that it is bad.
Also, the charging circuit may have died. Most electronics will work and work, and when they do die, it's usually when power is applied to them (turned on, charged, etc).
The fact that it does charge up to 50% makes me think the main battery is bad. Do you still have the original battery? Try it and see what that does.

The internal battery is used only when the main battery is discharged or missing.
As for a link, hit the wiki.

Thanks for reply, new battery i bought maybe 4-6 months ago i used it maybe 1 week, after that i turned off my device and left it for 4-6 months, so nothing should be happened to battery. I'll check device with old one, but it seems that device didn't work with original old one battery too.
Any other solutions, advices?
Thank You very much guys for help!!!!

problem with new hicap battery

hi all
Just put in my hicap battery-2600mAh yesterday.
all attempts to charge it have failed however.
----------
the problem-
with new batt inserted, i plug in the charge cable
no charge light (orange), no low batt light (red)
once WM is booted, it shows that the status is Charging
but stays stuck at 0% even after an overnight charge.
Taking the charge cable out, the phone is ON for about 20 seconds,
then goes into Standby mode all by itself but does not actually switch OFF or run out of batt after n hour of mucking about on it
-----------
it does not look like a dead battery as it is actually able to hold some amount of charge
a faulty battery perhaps?
or is there a special way to charge brand new batteries?
or a workaround to the problem?
thanks.

suggestions anyone?
resco2007 said the following in another post:
I wanted to let you know that I have the same problem with mine too : xda2 s do not like mosot chargers that is what it is but I have found a way around it, this is what you do- switch off the phone and then take off your batt for a split second and then put it back on , now the phone is off , now you can charge it,
It works for me and a few others
=======
but unfortunately ive not been able to get my phone to charge that way.
there dont seem to be a way for me to switch the phone off completely in that, when the little notch is push back in, it immediately boots...

p3300 no power; no charging lights etc. sometimes boots just fine

i have a p3300; no power lights when charger is connected; doesn't power on as well. battery is fully charged, battery and charger are both fine. but sometimes the p3300 powers on just fine; if i connect the ac charger then it also charges the battery. but it hangs in windows mobile 5 after some time (trackball and buttons and system does not respond anymore); after a soft reset no power/power lights or boot at all. then after some time and fiddling it might power on again and the cycle starts again.
i know it is a common problem; but is there a solution?
the backup battery (yes, there is one in it. the same as in the qtek 8310) gives me 0.20 volt. not sure how much it should be. but the backup battery in my qtek 8310 gives also 0.20 volt. not sure whether both are drained or that the voltage is normal.
will a drained backupbattery prevent it from booting up fine? or... hope to get it up running reliable again; great navigation phone with tomtom.
edited:
without the battery installed i get a red light flashing quickly if i put the 5volt charger on it; same if i connect an usb cable (connected to my computer);
if i have the battery installed; i do not get a red light flashing.
with the battery plugged in and the charger plugged in; i don't see any charging lights. but it does charges my battery; i started with 3.7 volt, and it is going up (now at 3.9 volt).
in both instances i cannot get it to power on/into bootloader mode.

i've got exactly the same issue
I was given this phone by my brother as its broken, i tend to get alot of his broken stuff anyway i stripped the phone down and found that the little battery inside had leaked so i did a little bit of hack wiring and bodged a 3.3 volt battery used in a PC to power the cmos chip well it seems to have sorted the problem apart from the fact there are two wires hanging out of the phone but i've also noticed this battery voltage has dropped to 2.6 v now and still dropping over the days i'm guessing i'm going to have to make it replaceable.
oh just for the record
my brother tried a replacement main battery on it originally and tried flashing it with a clean rom to try and fix it but it carried on hence passing it on to me

...
...to both of you...
buy a new battery..
leave it OFF while charging!!!
when the green led comes on (orange while charging... red flashing indicates battery is dead)
done.. turn it on..
batterys are cheep on ebay..
(if this dont work, pm me.. it could be something totaly differant but buying a new battery is the usual soloution for this common problem)
