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

(because i lost my stylus). i put the battery again. now it wont start.

btw, my ba is using wm5.

thanks

just to add, when i put it in cradle and connect to pc, nothing happens at pc, but steady red light appear at ba.

Battery is charged? (take it out and charge using cradle)
Is there "Serial/USB" on the screen (it's not enlighted, you need external light to see it).
If battery is charged and screen is empty not reacting for power and/or reset, you device might be totally dead.
PS: Styluses are not expensive.

jakubd.. yes battery is fully charged. i charge it separately from the ba. there is no usb/serial on the screen.
just when i thought to upgrade to wm6. damn. is there really no way of getting it back alive? hard to accept the fact that its dead.
ps: i have extra stylus, but the stylus hole is already loose. thats why i didnt use stylus anymore.

There is a chip in battery and sometimes it gets crazzy..
You must take off the battery from PDA, then charge battery in cradle...
after 1 hour you will put it on PDA and charge with pda...
It s solved...

shantilas.. i have done it. still nothing happened.

I might have killed my Battery (FIXED...for now)

Hey Guys,
I am running the Cell Pro 9.5 ROM and since yesterday my phone doesnt turn on.
So this is what happened, I never got a chance to recharge my phone yesterday and so I used it to the very last bit of juice. The phone kept switching itself off with the critical level battery warning and I kept turning it back on. So it got to a point where it wasn't switching on at all. So I pluged in the phone to the computer to charge and left it there for approximately an hour (the orange charging light was on), came back and tried to switch the phone back on and it didnt respond at all. Took out the battery, tried the soft reset button etc and everything else I thought of with no luck. So I plugged it back on and suddently it turned back on, did the boot up, loaded the touchflo and I saw the battery level was at "0" and then suddenly it turned of with a "tuck" sound (similar to a PC when you hold down the power button or turn the power off without shutting down). This has been repeating since then, I have left it plugged in and every 5-10 minutes or so the phone switches on by itself and shows the boot screen, go all the way till HTC animation and powers off suddenly. I have had no luck in turning the phone back on, I dont what is causing the issue - wether its the battery or the phone.
Please give me your thoughts....I am completely lost without my phone...
- issue was that the phone kept restarting as soon as the battery stored enough charge for a reboot. I pulled out the battery at one of the restart cycle as advised below and stopped it from repeating it. After that the phone let the battery charge without a restart, did not mess with it for a long while.
Never let the battery drain all the way down to 0%. Not sure if it affects the battery, but it sure will give you enough hassle that you wont repeat it.

The same thing happened to me last night... but mine works now. what I thought it was is that it kept turning on as soon as it had enough battery to do so then it would die and repeat... So every time it would turn on
I would take the battery out and let it charge some more and then when it quit turning back on I left it overnight and now its on...

Ok....I will try that and report back....

Sorry you pull the battery then the cord then put the battery back in then cord. Also it will take a lot longer if you charge it on the computer.

Never mind mine quit working again...

I managed to get it charging after pulling out the battery and putting it back again. Charged it through a computer cause i dont have my charger with me.
I turned it on and the battery said 40% and now every second or so it is dropping by 1%. I can literally watch it dropping down sitting here. The phone doesnt want to charge when it is on. I plug in the usb and the LED turns orange and then turns off. Now the battery is at 25%, This is litterally in about a minute or less. I dont know whats wrong, is it the Battery?

I had this exact same thing happen to me twice on previous HTC hardware (wizard). The first time I couldn't save it and just had to buy a new battery. However, the second time it happened I was able to resurrect it once I got it plugged into a higher-current charging source, like the wall charger it came with, or even most car chargers (that's how I saved it when I couldn't get to my wall charger). I had to let it sit on there for about an hour before it held enough charge to stay on, and another 2 hours before it was fully charged, but it worked just fine after that.

You battery may indeed be toast from what you describe. I have had the experience of totally discharging the battery and the device not coming on at all. I recommend that if you do this, you should fully charge it using the wall charger NOT the computer (if the computer works at all. it didnt in my case). I have done this a few times now and the battery turned out fine each time.

Thanks.....
My issue seamed to be fixed. I had to rely on a computer as I didnt have access to my charger and by the time I did my phone was at approximately 65% charge. I plugged it in and charged it all the way to 100%. Replugged it and left it for a little more while to make sure it got charged completely. I have been using it since today morning 9am and now it is 2pm at 73% after couple of calls, messages and emails.
Few more charging cycles with the wall charger and I am hoping it will be back to normal.

Power Button/Battery issue.

Posting for a friend who has a D.
Today suddenly the battery went dead and the phone turned off.
It was completely unresponsive even with a charger plugged in. We took battery out and left charger in, the light was flashing so we plugged battery back in but the light stoped flashing.
Thinking it was a dead battery we left it 'charging' and after about an hour the light came back on and the battery seemed to be charging.
Ten minutes later the phone turned on automatically and seemed to be OK.
Battey stats showed a massive massive dive making us believe it was the battery.
Now, it seems, the power button is fooked. Its completely unresponsive in the OS and recovery to both long and short presses.
I take it this means its a hardware issue with the power button?
I'm also wondering if these two things are related or its coincidental that they happened at the same time?
Cheers.

Today during sleeping, similar thing happened to my desire. When I woke up, the light was flashing and battery was dead, even though my phone was on charger the whole night... weird...

Galaxy S II Won't Turn On or Charge!!!

BACKGROUND:
At first, it just started turning off for no reason (probably a month and a half ago).
Then this week, it would start to randomly turn off, and start vibrating constantly when charging. After fiddling with the buttons, it would eventually find itself into download mode and then later turn itself on.
NOW:
Monday morning, after several days of draining the battery to 0% (due to me solely charging it for an hour a day), the phone went dead. Then, that night, upon trying to charge it and turn it on, it remained stuck on a black screen. After taking out the battery, it would continuously beep while still connected to the charger. As soon as I put in the battery, it would become COMPLETELY unresponsive, with and without the charger. After fiddling with it for over an hour, I put it down and slept, leaving the battery and charge in the phone.
Tuesday morning, I clicked the power button, and the phone flashed to the lock screen. It displayed it was at 0% battery, but I think it showed a charging sign. I used the phone for almost 2 minutes, checking my texts, before it again went completely black. The phone became completely unresponsive (no beeping or anything, regardless of anything I did). I connected it to a wall charger again, and left it there for the entire afternoon.
Then when I picked it up at around 6 o clock, I discovered that the continuous beeping stopped, and it would only beep after holding the power button for around 5 seconds. It could beep regardless of whether the battery was out or not.
After charging it all that night, I found I could make it flash the Samsung logo for a fraction of a second after holding down both volume buttons and the power button. I looked it up, and supposedly it brings you to recovery mode, but I believe my phone is switching off immediately after bringing up the logo.
At around 12, Tuesday night, I again decided to hold down the power button (just to reassure myself of it still somewhat functioning), and it powered on for around ten seconds (!!!) . It got all the way to the end of the pink loading bar screen, but then beeped and restarted. The second time, it lasted only around three seconds, without even getting to the loading bar screen, before powering off. It became completely unresponsive afterwards, no beeping, regardless of where it was charging and whether the battery was in or not.
Wednesday morning (today), after having left it charge all night, the phone still was completely unresponsive. I then left it to charge the entire afternoon (until now), and it was still completely unresponsive. I took it apart and played around with the power button, but it didn't seem to be stuck. I've now put it back together and leaving it connected to the wall charger once again.
What I've Tried:
Tried connecting it to Kies (computer doesn't even recognize it)
Tried putting into Recovery Mode (unresponsive)
Tried putting into Download Mode (unresponsive)
Switched chargers (unresponsive)
Held power button (beeps, now doesn't do anything)
Held both volume buttons and power button (beeps then quickly flashes samsung logo)
Cleaned off some of the micro usb lint with a tooth pick (coincided with the stopping of continuous beeping, not sure if it caused it)
What I think it could be:
Faulty power button (this is what I thought it was, but now it's not vibrating)
Faulty battery (I kept draining to 0%, but if this is the problem, it doesn't explain the phone not displaying anything when it's connected to a charger w/o battery inside)
Faulty usb charging port (I've heard it sometimes causes vibration problems. wouldnt explain the restarting).
Fried motherboard (phone has had some water damage, but I'm not sure if it's the MOBO, considering its symptoms)
HELP WOULD BE GREATLY APPRECIATED.

Not Alone
hey, this isnt really an answer, but maybe something to bump this up. Mine went last night.... won't boot, won't charge... goes into download mode but no matter how many times i switch cables, install Samsung drivers, install Keis, or anything imaginable- i cannot get it to communicate with my PC. if i could i would be able to fix this problem.
i really hope that someone will take a look at these issues and give some input. my call to Samsung was useless, i wasted hours with redundancy. I bought the phone used off Ebay in mint condition... have taken it apart and cleaned it with no avail. i fear that soon the battery will be dead and there's no way to charge it. sucks. Samsung really should recall/replace this because so many people have similar issues. whether it's the USB Flex or the battery or the motherboard they should be responsible. looks like ill be getting a nexus 4 afterall.
please let me know if you figure anything out.

It may be your battery, u need to remember why they tell u not to run the phone that way, the batteries our phones run need to maintain a certain charge in order to work correctly, if like u said u only charged it an hr or so a fah for over a week and drained completely more than once u may have rendered ur battery unable to hold a charge, in effect not allowing the phone to run its boot process, I would try a new battery, because beyond that the only other logical explanation is a hardware failure, stuck power button wouldn't render the device unresponsive only when the battery was put in like that, it would bootloop, have u ever just held ur power button in? The phone vib an shuts down a. Vib again n shut down, not become unresponsive, I would try a new battery, and if it works, respect the charge lol

I would agree, seems to be the battery. I bought 2 batteries and a 110V charger on eBay for $30. They don't have the NFC antenna in them but I've never missed it. Not only that but charging that way saves the wear and tear on the USB port.
