Wizard not powering on or charging - 8125, K-JAM, P4300, MDA Vario General

Hey folks,
I've been given a Wizard that isn't working, but I get to keep it if I can fix it . Just now the the problem is that it won't power on and I can't get it to charge. I don't have any of it's 'original' accessories (eg USB cable and charger). The USB cable I have is a 5-pin, which I believe is the correct one for this phone, but plugging it into my computer's USB port isn't having any effect, ie it isn't charging the phone. I have the charger for a Motorola Razr which has the same connector to plug into the phone, but when I try to charge it with this nothing is happening. I don't know if the phone is a G3 or a G4 and I don't know how to tell which it is. Can anyone give me some help here?

As the battery is fully discharged and dead,It won't charge through usb cable with pc,as it only provides a charge of 0.5 amp,it'll also not charge with a Motorolla charger,it can only be charged through a wall charger which is capable of giving output charge of 1.0 amp or you can try a 'Jump' start the battery.But if the battery is faulty,it won't charge at all,you'll have to get a new battery.

Thanks for the reply zabardast.
How would I go about jump starting the battery? I'd like to try it before I go out and buy a new one.

How to 'Jump start',read my post in this thread,hope you get it right and working.
http://forum.xda-developers.com/showthread.php?t=374108

if you're good with electricity and have a DMM or Fluke you can also check the resistance on the battery and use a steadysize capacitor to try and jump it. it might burn the battery but it doesn't work anyways so you don't have much to lose.
the capacitor size can be calculated using:
C(capacity) = 1/wR - where w is the network frequency.. wherever you live. (should be easy to find it. usually 50hz) and R is the value you see on the DMM.
buy that capacitor and charge it using either an AC source or another wizard battery (fully charged) even tho i doubt it would have enough power to charge the capacitor... and then you can jump your battery. an AC source would be a great option since you can set the frequency to the exact network frequency in your house.
Hope it helps..

Iv'e actually had similar problems, and I've oddly enough found that if I used the car charger it would turn it right on. I went to EVERY Cing/AT&T, T-Mobile store and used every charger and nothing. I work for Asurion so I see this happen all the time, Im wondering if I just replace the battery with the High-Capacity type if this problem will be over.
Also just a side not, but it only seems to happen when I leave it off the charger and it shuts off by itself

yep
i had the same problem. and as of today just bought a new battery! my love is fine and alive again!!! the battery is only around 10.00 and is well worth the money to have my babe back! do the same man! you WON'T be sorry ... and it's worth 10.00 not to have to mess with tryin to jump it.

HTC not charging, battery dead?

Helloes guys and goils.
I have a HTC wiz, and for a good few weeks now I have had problems with it.
First off, It would NOT charge through the Wall Socket OR USB, I let it run down over XMas and it's not been the same again.
It just will not charge or come on.
When I plug it into USB it looks as if it is charging, with the Orange light and The power bar turns to the socket looking thing, but when I leave it to charge it just goes off and doesnt come back on.
When I plug it into the wall socket the HTC does not respond.
I have been asking my mate in work to put it in his and charge it via HIS wall charger, which has worked a few times, but I seem to be getting a very awful run out of my battery.
I am thinking it is the phone and NOT the battery as i first thought, I dunno, im scared of throwing up £30 notes on a new battery only to find it is the phone.
What do you guys think I should do?
I heard somewhere that it is a SOFTWARE based charge and not a hardware based charge, what does that mean?
DO u think a flash would help it? I cant see it myself.
Or is my HTC just goosed?
Well
I can speak from experience when I tell you my wizard nuked 2 batteries...
how I dont know.
Hopefully one of the gurus can shed some light on your situation

If you do replace the battery, look on eBay - I got a new 1250 mA battery (there are also 1100 mA versions, don't get that) for $13.99US including shipping - works great!
Make sure its nothing simple... Try the USB cable plugged directly into the computer without using a USB hub (if you are) and different USB ports on the back of the computer. Also try different outlets for the AC adapter. If still nothing else I'd even ask for help from your local cell phone store (put on a sad face) and see if they'll lend you a power cord and or swap out batteries to see if they can reproduce the problem on a different Wizard, battery, etc.
There has been many posts on this subject with several different fixes.. i would suggest searching and reading and you can find your answers
My case
Hi,
I had somewhat similar problem with mine. My porblem was that I bought the Wizard with a Motorola charger. It had the same mini usb plug and when I plugged it to charge, the led on the wizard was orange and the Wizard indicated its charging, but the moment I unlugg it, the battery indicator was coming back to its previous state. My solution is to use the PC USB to charge it, on a couple of occasions I had the battery completely drained and had to "jump start it" by connecting the wires from the usb directly to the + and - of the battery. Even used once my good old AA Ni-MH charger to jump start the battery and it worked.
So perhaps you are not getting power from the cable, why not try with different charger or charging from another USB source (PC).
Hope this helps
Just happened to me tonight. Thought that my Wizard was toast as well.
I merely took the battery out for 10 minutes, put battery back in, and plugged device into original wall charger. All is well now.

Wizard looks like is recharging, but in real it doesn't!

Hi guys,
my beloved qtek 9100 is having some weird behavior since last week: i let my battery drain to 9% and then recharged. The phone would not recharge it, showing a red led. After lurking and learning about this problem on those devices I made a "starter" with three 1.5v batteries and gave the battery the necessary tension to start recharge cycle.
I thought that would be the solution but no: the phone kept stopping recharging at 25% or, the next time, at 75% with no apparent reason. Then, i tried many solutions like directly charging the battery with a cut usb cable, with the stock charger, with powered on phone, powered off phone, etc. No clue.
What leaves me shocked is that the battery, even when at 75%, drops suddenly to 0% after enabling the radio module thus killing the device...
An important note: same behavior with two different batteries...
I'm going nuts...
Problem still unsolved. Today i left the device recharge at 100% (took about 3 hours), detached it and tried a rom downgrade. Obviously it died at 50% of rom upgrade procedure. Sweet...now it's almost bricked, bootloader screen and recovery procedure to be done
What could it be, an hardware failure?
Hi there, same problem here: I have the phone with two batteries, on half a year old, one brand new. The batteries DO charge on another phone, but after a regular charge is gone, my phone never gecharges the batteries. It might be the charger circuit? If not HW, is there any chnce to do some SW stuff?
Unfortunately this thing s just a brock now ...
Bye

It's good to find someone with my very same problem...although i've got no solution, still!
Is there someone out there who knows how much would cost a fix and if it's an hw issue or not? Would it be possible to fix it via DIY?
Thanks in advance
Someone suggested me to test the current output on the main contacts to see if the device is actually supplying power to the battery.
So i plugged the wall-charger on the device, took a multimeter, checked the output: the device is supplying 3.5-3-7 volts. So, i suppose it is correctly charging. Why, then, after a turn-off / turn-on the charge level drops after showing as completed?
Could it be a sw problem, then?
USB voltage is 5v. If you are not getting 5v on the USB plug coming from that charger, then that is probably your problem. Have you tried using a USB cable to plug it into your PC to charge?

Thanks for the hint
I suppose the problem is another...in fact those 4 volts are coming from the battery itself. Pluggin in or out the power plug doesn't make any difference.
I tried taking out the battery and there's no power coming through the main contacts of the phone. Is this the right way to check or should i use some different method?
Thanks again
Last question: is there someone who could show me where the recharge circuit should be on the mainboard? Have you got any information about the ease of a diy repair and about the price / availability of the spare part?
Thanks in advance

Are you using the wall charger or with the PC. Cus you will get more power input from the Wall. As so i dont know the reg key off hand but if you change one thing you can make it so your phone does not charge off the PC. Maybe you have found a new one!

With both the wall charger and the pc usb plug. Checked the registry key and no way, it's ok.
It's really incredible, the total charge cycle takes a couple of hours, like if it were charging regularly, but after unplugging it goes down. It is like if the "carge counter" or similar records the charging, with the battery actually not receiving power.
did you solve your problem yet?

please help with my MDA Vario..

i have an MDA Vario which doesn't work anymore.
it won't turn on or do anything .
it was working fine before i let the battery run out completely, as i forgot to charge it.
i don't have a proper charger, instead i was using a USB cable for a digital camera which had the same plug that fit in the Vario. it used to charge it when the phone was switched on.
does anyone know how to fix this?
do i have to buy a new charger or a new battery?
thanks.

Search here for the 9volt battery trick. There used to be an issue with older ROMs on like the Cingular 8125 where it wouldn't charge once the battery dropped to a certain point. There was a trick to "jump start" the battery with a 9v battery. Then it would charge again via USB or wall charger.
Once you do get it charged, you probably need to make sure you are on your carrier's latest ROM.
Note that while Razr chargers also use the mini-USB plug, I've heard some of the off brand Razr chargers will not give a good charge to a Wizard.
I used to have a hp pda and left it in the draw for a few months and couldnt charge mine, i had to buy a new battery.
Dont get a Razr charger it wont work.

Another possibility since the battery is completely dead is to plug in a charger (really should be a wall charger and not USB from a computer) and just let it sit for about 5 mins. Then press the on button (with it still connected to the charger) to see if it will turn on. If so it should then charge on up. If it doesn't I'd suspect the battery may be damaged.
thanks for the replies, i'll try the things you said

XDA Mini S + USB Charging

Not sure if this is right part of forum, but here it goes.
I am having an issue with the charging of my O2 XDA Mini.
If my battery dies, with still a small bit of power left in it (enough to get splash screen) and I go to charge it works fine no problem. Now over the wkend my phone died on my and I left it till this afternoon when I tried to turn on, it wouldnt turn on at all (not even splash) because obviously the battery is completely dead. Now when I go to plug it in, it wont charge, from USB cradle, the little orange light to say that its charging doesnt even come on.
Last time this happened I eventually got it to work via a friends socket (plug) charger, rather than USB, charger. Is there any reason for this or anyway that it can be fixed that even when the battery is completely dead I can charge it from my USB cradle.
Any help would be apreciated.
Thank you in advance

Sorry to bump this, but does anyone have any idea. I beleve the cause of this is due to the fact the USB power from the PC isnt enough to get the charging process started, is there anyway to get this done via the cradle.
Thanks
Rattlehead
You'll need to use a charger that plugs into a wall socket I'm afraid. This happened to me once & that was the only way I could get it to work. If you search on Google, you'll find methods that involve a stripped down usb cable, but a wall charger is definately easier.
Good luck.
Should any usb based wall charger work?
I have a Motorolla one and Ive tried that but that didnt work.
I know for a fact that when I use my friends one it works and will charge, but he aint round for another 2 weeks

You cannot charge a totally flat battery through usb cable using PC,cuz it only supplies 0.5(500)amp,whereas to get the dead battery back into charging,it requires a supply charge of 1.0(1000)amp,secondly you can only charge the phone via usb if it's working normal and not when it's dead,as you cannot boot into OS.
Therefore,it'll only start to charge with a 'Wall Charger' which only supplies 1.0 amp,your friend's Wall (Mains) charger must be suppling a 1.0 amp charge.You cannot even charge it with the Motorola usb charger cuz it also supplies only 0.5 amp.So try to get a Wall (Mains) charger to get it start charging.
OR,
Yes! you can Jump start the battery using Motorola charger,but you'll have to sacrifice the motorola charger to do it,as you'll have to cut off the usb plug of the charger cable end and attach the 'Red' wire to the '+' (Possitive) connector of the battery and black wire to the '-' (Negative) connector of the battery and give Shock Charge to the battery for 10 seconds,repeat this for 4/5 times,it'll give the battery a jump start and will increase the 'Pulse' level of the battery,after that put it in the phone and check if it loads up,if it does then you can charge it via usb cable connected with PC.
Good luck
BTW ! there's an excellent thread regarding charging to avoide the battery to go flat and saving from getting into this situation,it wud be very info for you,check it also :-

You are the Guru ~

Here is a simple way of solving the problem, go and buy a charger, they cost next to nothing.

Wing won't charge

Hey, just bought my wing (upgraded from dash that I dropped down my ice fishing hole) and it won't seem to charge. I've tried everything from leaving it off to different chargers (off brand and htc supplied ones) and I can't seem to get it to charge at all. Thanks for your help!!
Make sure the charger your using is rated at the correct voltage, ohms, watts or whatever the hell is important. (im not an electrician)
With my old MDA, I was trying to use a motorola razr charger, and it wouldn't take a charge at all, because apparently if the chargers aren't "made" for the phone, they won't charge the battery fast enough or something like that so it doesn't take.
Try different things, ... Soft reset the phone. I've had my phone 'crash" so the screen won't show its taking a charge when I plug it in ... so soft reset it?
I dunno, maybe try taking the battery out, and put it back in.
if nothing works, You may just have a phone with a faulty usb port?
Thanks, I think I'm gonna have to call tmobile and see if I can't ge a replacement something. Sucks that I'll have to redo my iphone stuff but oh well!
try charging the phone with the wall charger first...then connect to the comp...for some reason...some phones (at least the wizard use to be this way) wouldn't be able to get a charge out of the computer usb if the phone battery dropped down to 1% or so...I think the usb has a slightly lower voltage than the wall adapter...
