I have a 602 with EOS and this weekend it just quit. Wont boot, no charge light when plugged in cant get it to do anything, any help on this or do I have a Motorola paper weight??
Would have thought a complete failure such as that would suggest a power problem.
Did the battery have a reasonable charge before the device quit?
You may have a dicky power supply, perhaps borrow one of you are able to.
If not check the power supply output with a suitable voltmeter if you have one.
Power supplies for Xoom have a habit of dying young apparently.
Check your power supply. Sometimes the after-market power supplies don't hit the mark inside the device.
Did u tryed to re-plug charger to power ? This help some time for me - i do not know why this happend. But i never pluged out my charger so sometimes it just dont charging. It its still same and no power , change 1 charger . If it wont help then its xoom related . Mainboard or sth inside...

Hi all,
Right, the battery on my XDA Mini S was getting low, so I plugged it into the wall charger (not an official one, its a motorola mini usb charger 5v, 850mA)
It was left charging for a couple of days. I think? Someone could have turned off the switch? But the switch was on this morning
Anyway.....It doesn't boot, no signs of life at all, if i plug it into the wall charger then there's no lights.
Doesn't even go to boot loader.
No response when plugging it into USB.
I've tried hard reset, no nothing.
It's weird because its been working perfectly.
I've been googling and reading the forums here.
I've had a go at "jumping" or reviving the battery. Maybe I'm doing it wrong?
I bought a 9v battery, took apart a mini usb cable and removed the red and black wires. I've been holding the wires from the 9v battery connecters to the tips of the + and - plates.
Still nothing.
Can anyone suggest anything?
Surely it can't just become a paper weight suddenly?
This hasn't happened from flashing either.
I've also tried another charger, which didn't work, so the charger isn't the problem.
Wohoooooooooooooooooooooooooooooooooooo!
Fixed it.
I tried "reviving" the battery again.
Except this time I tried connecting the + and - to different plates.
My sticker on the back of my battery lies, and tells me the wrong + and -
So I googled what an XDA Mini S battery should REALLY look like....voila!
better buy a 1AMP Wall charger and don't let the battery completely discharge.
Yeah, I heard this problem with a friend of mine as well. Battery ran out completely and it wouldnt charge at all (seems that it only charges if the phone is on, so, yeah, figures).
My suggestion on that case would be to try something else to charge the battery alone, dont know a specific charge but sometimes little things like putting it in the freezer for some time works to give it a tiny little life back, enough to turn on the phone, you never know.
hey i have same problem with that
im using 9 v batteries and connect to mda batteries
but still nothing
what must i do. . . . . .
would someone help me
i try all but still nothing
2 days a go my mda can on but only bootloader and then off
till now im so confused
please help me
i run out of battery too and now can't find anyway to turn on my mobile to charge. need some help too. hix
someone help us........................
ok, found the way and revive my phone
1, take a usb cable and cut it
2, there are 4 wires: red,black,white and green
we need red and black so cut those white and green
3, see on your pin, there are 6 bronze square, the frist and last have + and - icon on it
4,connect usb cable to r computer
5,red wire to the square has (+) icon
black to other
wait about 30s
6, place pin to yout phone and power on, u have some second to recharge it
nice, i'm charge my phone
it's not work for me

Hi,
My wizard main battery (wiza16) was very low and the wizard stop with a message “The internal battery is very low”. After coming back home I have tried to charge but it is not taking charge and didn’t turn on anymore. I recently bought a new battery (wiza16, 3.7 VDC, 1250 mAH) thinking that it will work again but still the same problem, wizard is not taking charge or turn on.
Can anyone help me?? What can I do to start my wizard? Do I need to change the tiny little battery (which is inside the wizard)? Kindly help me.
Wizard service manual
Hi,
See if when you connect the power plug the led turns red, if yes....
If Charge light is red when plug in AC adapter, it means the main battery is not charge enough and can’t power on,
You just need to continue charge unit the light become Amber
If not, i think you have a problem.
Check if charger its working and if its pluged.

Wizard Battery discharge completely
Hi,
Thanks for quick reply. there is no light when i connect my wizard with PC. I don't have the AC charger, I have lost that for long and was using my PC usb to charge. trying to get one AC charger.
There was no problem with my wizard, just can't turn on after it's battery discharge completely. Even the new battery couldn't turn that on.
You'll need the original charger if the battery has complelty discharged as it will only charge from the computer if the phone is powered on.
This happened to me before.
There is a trick to giving the battery a quick charge which will give it enough juice to boot the phone up and allow it to charge from usb. its not recommended but works.
You will need a spare usb cable, cut one end of, strip the wires back and connect the red wire to + and the black to - on the battery, only do it for a short period, about 30 seconds while conneted to your computer.
You may need to give it a few 30 second bursts to give it enough juice.
Pop the battery back into the phone and switch it on while pugged into the PC
Took me a few attempts to get enough charge in the battery for it to boot up.
Wizard battery
You can also use a 9V battery to jumpstart your battery. But then you have to be more careful. I connected the 9v battery to my Wizard battery for about 15 seconds, then tried to start up my device. If not successful I started again with 15 seconds jumpstart..
But you can find more information here in the forum: just search for jumpstart or something similar....
Regards

Wizard Battery discharge completely
Thank you all for information. 9V battery method didn't work for me. Looking for AC charger online and get a link (http://www2.dustin.se/pd_5010073700.aspx). Do you think this is the right one? If yes, then I can order.
yea that's the right one but if you have a friend with a ppc or maybe a razor you can use there charger most ac adapters are starting to use mini usb just a way of saving some money even though having an ac adapter is good
could also try and get one of those usb plugs that you can plug up to a wall and plug in a usb cable into the slot
but don't take my word for this wit hmy wizard i haven't had it shut all the way day
if anybody can verify this would work
AC charger not also working
I have got the AC charger yesterday. When Connect the Ac charger first time the red light on my wizard showed for just half second then dissappear. Still let that connected for whole night but no response.
Thank you all for help.
@Keland44, most Razr chargers dont work, they MUST be at least 850mA in order for the Wizard's battery to receive anything. The older Razr chargers are sometimes as low as 350mA, but the never ones are as high as 1.2A, so you need to read the label on the charger itself to be sure.

Yup that is about right,
If the battery is complelty dead, then you need to original charger.
If you have got the right charger and you get a red light and it goes off. your phone might have a problem.
This happened to my last wizard after stupidly trying to dry out the screen after getting it wet which stopped the touchscreen working (i was drying it out while the phone was still on) well my wizard crashed.
Took ages to get it back on but it was very unreliable then one day, it wouldnt go on and charger done nothing. Unpluging and pluging the charger in several times got a red light on.
Sometimes i could get it to turn on, the charger would charge for about 5 minutes then the phone would die soon after.
Your phone might possibly be bricked.

I Have Same Problem with my wizard
Yesterday my wizard goes died, i think the battery out
when i came home, i use AC Charger for HTC Universal, for 1st time its red light then off,
after 15 minutes orange light, i try to turn on my wizard and works but only in boot loader 5 minutes again its going off again
until now my wizard wont turn on
some body help
Hi everyone. I've made the error of letting my Wizard get to 0% battery charge... so, when I tried to charge it up, no deal. I read around why, and I understood how this phone charges the battery: ok, no big deal. I followed a couple of posts here, on how to revive the Wizard. I used a 9V battery to let it boot... and it booted! But the battery never kept charge... well, I dunno: the battery status screen showed some percentages, but to be honest it never kept charge, or I had already fried the phone, thus the battery didn't get any charge/the phone couldn't start.
Then I got smarter, I read that a spare battery and the original wall charger would've been better... I took another battery, I attached its 1A wall charger... red blinking led, which sometimes stops blinking.
I fried the mainboard, didn't I ? I'm starting to think that 9V is a lil bit too much.
UPDATE EDIT: Well, I've done some electronic necromancy... the two batteries I had won't charge. I've managed to piggy back them with a power supply, they can boot the phone. Whee. Then I plug in the original wall charger, and... after 5-10 minutes, bang, power goes down. How much voltage do those batteries output after this little trick? 0.00, 0.01. Well, I just bought a new battery... but I still fear I might have fried something. I'm gonna charge one of those old batteries with the power supply and see what happens.
How to Recharge battery. When battery goto 0%
try this.. mine worked. Take a USB Cable cut the small end of the usb cable
not the side that goes to the computer. Strip the wire . all you need is the
red and the black wire. the rest fold it or cut it short. First : take the battery out of the phone. SECOND: Plug the usb to the computer ** becareful don't let the open wire touch each other it will shut your computer down or burn your usb port. THIRD ut the red wire to the + (positive ) and the black wire to the - (negative) on the battery for 1-3 minute. then put the battery back in the phone, turn it on , then plug your charger quickly. Hope this help you..
Thanks for the advice, goon1. I'm going to try this tomorrow, you'll have updates
The battery kept charge for like 10 minutes... then, bam, it's dead. It won't charge with the wall charger, it won't with the usb charger, nothing at all. I hope I just overloaded it and broke when I clumsly tried to reboot my phone, which I'll discover as soon as my new battery will get here from HK
that mean you have a bad battery. MADE IN CHINA. doesn't live up to it name.
the battery from there loose it charge quick. Remember they run 220 and we run 110. Just get a good battery from USA.
Batteries do wear out, and it shows when they wont hold their charge...
Before you conclude your phone is damaged, buy and try a new battery. ;-)
Peter
UPDATE
Since I didn't want to spend too much on a phone I consider bricked, I bought a 3$ battery from HK.
New, supposedly working... the red led is watching me.
Another detail: the power button does not work. In the rare cases where the phone booted, pushing it to go in stand by didn't work.
I'm more and more convinced that I fried something.
I got in a really nice and sleek Impression I10A Tablet.
The Connector for the USB/Power has broke and, unfortunately, it's the only connector available for power..
http://sjfm.us/temp/i10aConnector.jpg
Now, my first thought was to replace the motherboard. No such luck. Finding ANY kind of Impression parts is difficult... Second choice was to replace the power connector itself. Tedious and a pain in the arse, but doable. But I have had bad luck IDing power connectors for tablets (most notably Kindle Fires and the MicroUSB) so if anyone can help identify the above connector...
"I am all ears"
-Ross Perot, 1992 Presidential Debates
Anyways, so then I got creative and, just to confirm "Proof Of Life" (so to speak), I hooked up a 12v 2a power adapter directly to the battery connector (Red Box) to bypass the damaged power port (Blue Box).....
http://sjfm.us/temp/i10aPower.jpg
.....on the PCB and viola'..
We have a heartbeat!!
OK.. So now I am thinking that, if I am lucky, the 12v power will power that tablet AND charge the battery.. But then I am thinking that there is likely more to charging a battery than simply applying a power adapter directly to a battery and getting a charge..
Sure enough... When the battery AND the 12v power is hooked up, the tablet boots up under the battery and then dies before it can get to the dashboard..
When the 12v power alone is hooked in, the tablet boots up fine and shows a full "charge"..
So, here's my question..
Is there a way to kludge a power connector to bypass the damaged port and power the tablet and charge the battery..
In the alternative, can anyone point me to a knowledgeable source that might be able to ID that type of power connector??
Thanx in advance..

Never connect a power supply directly to a battery.
That's a recipe for fire and explosion.
12V? Why do you think that anything is 12V?
Does the stock AC adapter say that?
If you want to get this thing working properly you'll have to figure out on the circuit board where the AC adapter hooked in.
If you are sure of what the total battery voltage is (how many cells) then you could also hook a power supply in with the battery disconnected.
Thanx for the reply. Apologies for the delay in responding. Was out of the country for a week... In the middle of the Atlantic Ocean. No web access!!!

Yea, as I soon found out. I was tinkering with it longer than normal and a small little component near the power connector released the blue smoke.. So, I think that MB is borked..

Yea, the stock power adapter for the unit is a 12v/1.5A power pack.

I do plan on repairing that component. Eventually. Once I do, I'll put your advice into practice..

A friend has given me his 2012 Nexus 7 because it wont switch on.
I read many solutions on how to fix this but nothing works. I'm getting no responce from the device at all.
Heres what I've tried:
Leaving on mains charge for over 24 hours.
Long press on power button (30s+)
Disconnect battery cable & re-attach it.
Un-plugging & re-plugging in power & then trying to power it on.
Theres voltage going through the usb socket & I've measured power at the battery connector with my volt meter but its not powering up.
Now I've read that the Nexus 7 normally has a 5V/2A mains supply, however, I'm only using a 5V/1A supply which I use normally for my phone. Could this be why its not powering up as its not getting enough voltage to kick start it from being completely run down?
If its not the mains power, any ideas what could be causing the problem & is there any way to fix it?
Thanks.
