Hi Friends...My O2 Atom Pure battery is dead...I have opened the battery and tryied nokia battery but it didn't satisfy...and now I dont need a battery backup anymore...So I want to run the phone on online mode(that means to operate it while connecting to charger or USB/PC)...What mods should I do to run the phone online...tried searching threads but couldnt get help...pls Help Experts
I opened the battery and I found 2 components , the battery circuit and the battery that holds the charge...I removed the packet that holds the charge...Now the Battery has the circuit board only...
Now + and - terminals from the battery circuit board were then placed on nokia battery(opened batt)...the device worked...(it means device is fine)
1) Now I removed the terminal from the nokia batt and tried charger for booting the device the charging light blinks and device fails to start...
2)Then tried connecting plus to minus of the battery circuit board...doing this the the charging light lit up normally...boot screen appears up for few seconds then device goes off..
What mods should I do so I get the device working online-mode on the charger or USB cable Only(like O2 Joggler)....Experts Please Help...I dint find any similar threads that helped me...

red light means extremely low batt.....guess your battery is faulty
i got the same thing.
and no it's not the battery.
it's the charging circuit on the main hardware isn't working.
open your phone and check the five small wires that they connect the mini usb to the main mother board, one of them must be cut.

so, is there a solution to this? or there really is nothing more for the device but the trash bin or for spare parts?
Have you tried this?

If you already replaced the battery and nothing, and you want to get rid of dear Uni place it for sell in parts on marketplace, a lot of people will go for it!

I had exactly the same thing with my old battery,after my try to discharge it with a lil electro-motor. then i found a post of a guy with the same thing,who fixed it-by "zapping" the UNI battery with a 9V battery,connecting + to + and - to -,for a few second. I tried it without thinking twice. It worked for me. Dunno how and why,but it did. I use the battery again,normal. But beware,it is dangerous to play with this type of battery,it can explode. Do a search on this subject and you will see
I agree with keeping_sg
how long have you left your uni on the charger?
just plug it in and leave it on the charger all night and see what happens.
I bought yesterday a 4800mAh battery from Hong Kong... 10 euros included shipping + FREE black back cover
Good battery life but still prefer to carry 2 original sized batts rather than get that big one, making even bigger our Uni
Respectfully,
Yes, that absolutely means your battery is dead. Try charging for a few more hours and then turn on your PocketPC. If the error persists, try changing the battery.

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.

Under the "Hacks & Tweaks" section, go into "Technical Stuff".
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!!!!

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.

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)
Hi,
I have strange problem and I think it's from the main board..but I just need experts opinion first, so may I could solve my problem without changing the full motherboard and save some money
my tablet working fine but I can't charge the battery, when I connect the USB cable it shows me the battery status 100% !, and the device instantly powered off if I pulled the USB cable from it.
when I noticed that I did a simple trick, I completely removed the battery and connected the tabled directly to the charger, and it shows me the exact same status, I could even power on the device and use it with out battery inside, just counting on the charger, and the device still show me the 100% battery statues
At the beginning I thought the problem is from the battery it self, so I decided to buy new one, but the same problem still exist. so....I think my main board is working fine but with a simple issue...it can't detect the battery.
so my question is...do I really have to change the main board completely, or I can just fix it by replacing a small part...like the battery port or something like that??
Same problem
My husband has the same problem, his tablet only works if the charger is plugged in. As soon as you pull out the charging cord it shuts down, but when you plug it back in it reboots and works. Tablets are mobile device yet he cant move away from a plug
Everything else about our 8.4 Pro is wonderful, even at 3 years old so we'd like to find a fix. Any solutions?
what recovery says ????
My phone's battery wont charge anymore.
It charges only if I first disconnect battery, plug charger on phone, then turn on phone to boot in android, and then connect battery with phone.
Is this a hardware or software problem?
(i am guessing that there is some switch when battery is full, that it stops charging battery, and only powers phone) if its hardware based, which component should i change
When the 1st time phone stopped charging battery, i did factory reset and it charged battery normally for few times, and now even factory reset doesnt suffice.
Charger and cable works on my other phone and tablet without any problems.
Usb port on phone is probably ok, becouse phone always turns on without battery
Maybe the battery is faulty? I mean if the phone turns on just fine while connected to a power source and no battery installed, I'd assume the battery is dead.

When i charge battery with this method, phone works ok with fully charged battery without charger plugged in.
But when i need to charge battery again, i have to repeat those steps i mentioned before.
I tried a lot of steps mentioned on A2 (not lite) forums, as i seen a lot of users had similar problems tried all options without success, some have changed battery, mb and usb port, and that didnt help either.

Probably your phone's USB connection loosen solder, one of the terminals (either ground, data connection or positive terminal) might loose or gets rusted and thus, never charge phone properly. My SM-J500H (my other phone) does the same syndrome that it just charge but not really charging at all, because of 'green' rusted USB port.
Try checking your USB port and if there's some rust in there, or some loose solder. Try also change USB port (by your technician) if it still persist.
hi, have you found a solution? because i'm having the exact same issue.... phone only charges with the method you mentioned
