bougt a xda2 from ebay,
it works fine but is missing the chargeing unit at the bottom so i can not sync it with the cradle nor charge it, unless i take the battery out and charge it on its own in the cradle, is there any chance this can be fixed,
the actual clip inside is missing so i dont know wether it was soldered on or its a clip and can i get a replacement
any help will be appreciated
my wizard battery won't charge.
i have tried another battery and another rom with no change.
wehn i plug in the sync cord, the izard reognizes that it is on external power but just won't charge the battery.
any ideas.
thanks
...try to find out, by measuring, if the ±5Volt DC is present on the pins on the inside of the ppc which is needed to charge the battery. Probably your charging circuit is busted and the ppc should brought back for repairs...
thanks for the response
what is ppc
where do i measure the voltage.
when i first connect the sync cable, it starts to charge for one or two seconds and then stops and reverts to a normal non charging screen.
thanks
PPC stands for Pocket PC
What you speak of, I had the same problem on my wizard.
My battery finally died and I couldnt re-vive my phone.
I bought a new battery off of ebay, put it in, plugged it into the charger that came with my phone, let it charge overnight and I havent had a charging problem yet.
My advice, as well as alot of others on this board, dont use any other charger other than the one that the phone came with. I know I wont be.
...inside your ppc,when you remove your battery, you'll see different connection pins which are normally connected to the battery. With power attached (and without battery) you measure between 2 pins at a time. WATCH OUT for shortcircuiting, be careful!!!. You can use an analog or digital voltagemeter. I don't know which pins, so you have to try it yourself.
You should measure ±5 Volt DC which's delivered by your adapter. If there's no power then your charging circuit is defect and you'll have to let it repair...
reading about a volt on the internal pins that connect to the battery.
so it's the charging circuit.
damn
I had the same problem twice with 2 different batteries. it seems if the batterie dies completely, the device can not recharge itself. something like a car, you need to have enough juice to start the car so you can recharge the battery.
I took 2 paper clips that i used to connect the charger directly to the battery( bypassing the phone). you need to be careful with that, make sure you connect the right battery pins. I left my battery like this for 15min, just enough to have aniough power to start the phone and continue the charging process regularly.
As mlarif said the battery can fail to charge if totally discharged. So if you are not absolutely certain your circuit is faulty there are at least two threads here describing how to butcher a usb cable to jump start the battery.
Sorry I can't remember the colours of the wires off the top of my head. But a search may find the relavent posts.
...you can also use a 9 VDC battery to give the ppc batteries a boost for a few seconds. But indeed be sure to use the right pins
(btw did you measure any VDC on the batteries..?)
Hi,
I currently repair XDA Exec's for a client of mine who use them for their delivery drivers. They are constantly breaking the screens which are easy to fix, but more often than not they smash off the usb connector and leave it rattling around inside. This is not usually a big problem to fix unless the pads that the 5 pins are soldered to have been ripped off the board. I have found that even if I successfully replace the connector with a new one and solder the two outside pins (which are the gnd and 5v pins) the battery will not charge. The puzzling thing is, if I remove the battery, the red led comes on, presumably indicating power to the device. As soon as I connect the battery the led goes out and the unit boots up only to reveal that it is not charging. So I'm presuming two things:
1. There is some other electronic component damage in the unit caused when the connector broke (due to it being on the end of the charger cable at the time, if this is the case I will scrap the unit)
2. There is some feedback from the battery that the charger needs to continue with it's output and because I didn't reconnect the data pins it won't charge.
Does anyone know how the charging circuit works and what pin / connections are required for charging. I guess the same principle will apply to many PDA's & mobile phones.
Thanks

Q: Suddenly my car charger (cigarette lighter plugged) is not working anymore. After 5 mins. my device stops charging..... is there anybody having the same problem and knows how to solve it?
If it's after a period of time maybe a battery contact issue?

If you've already read the sticky posts relating to car chargers and your (mystery brand) charger isn't one of those, then maybe your phones battery terminals and connectors need careful cleaning with a cotton bud moistened with contact cleaner or IPA. I had a problem with my mains charger ceasing to charge my TyTN II after a minute or two a long time ago and after cleaning as described, the problem went away. Be sure not to spray the contact cleaner or IPA onto the phone or battery, only the cotton bud/Q-tip and then gently rub that on the spring contacts and battery terminals. How does charging via mains adapter or PC USB port go?

It still could be a battery contact issue as voltages may differ slightly when using the car charger compared to the other forms of charging. As an example if the Kaiser is set to stop charging when the supply voltage drops below a certain value and the car chargers voltage is lower to start with (and fluctuates with normal driving/electrical usage) then that may explain things. It's well worth doing this cleaning every so often anyway as a matter of course so give it a try and see what happens.
Additionally, could heat be a factor eg if it's sitting on a hot dash or near heater vents (the device is designed to not recharge above certain temperatures)?

Thanks for the advice, i will give it a try
if you have any adapters that allow for another usb input, nice a headphone adapter, or the HTC Multifunction Audio Cable YC A300, a ycable or anything with a USB in, try that first.
if that doesn't work, take the unit into your retailer and they will give you a new (or refurbed) unit, as your USB port may have a pin or two out of whack.
This may be weird, but my tilt used to charge just fine from most USB chargers(car, AC, usb cords). One fine day it quit charging off most chargers except the official AC charger from AT&T. I tried to fiddle with the USB pins inside as one looked like it might be a bit bent/damaged. No luck.
However, yesterday I noticed that My Settings->System->Power->Advanced settings page had following option checked:
'When device is turned on, do not charge the battery when connected to the PC'.
Once I unchecked it, it started charging of PC USB cables (obviously), but strangely enough also charging from my car charger(s). Hope this works out for you or someone else...

It is probably because your normal USB pin 4 and 5 in the cable of your other chargers are not shorted to signal that there is no data connection. So your phone thinks it is connected to a PC (or a device which might send it data), hence not charging the battery according to that setting
I have a similar infuriating problem, i have had a MDA VArio III for over a year now, had an issue with my last one and had a replacement issued in October. Now i have used the Brodit active holder (ciggy lighter version) since day one over a year ago and wit the new MDA as well. now all of a sudden phone will not charge in the holder, borrowed a friends active cradle still no charge, used a no brand usb ciggy ligther charger and charges fine!!!!
When phoe n is placed in the holder orange charging light comes on but phone does not charge and the light goes out 5 mins later!!!
any ideas anyone???
thanks
Matt

Problem solved - Pin 5 on my phone was ever so slightly out of alignment, bent back into place and all is now well! strange it only affected the brodit holders, nothing else!
Car charger failure explained
I also experienced this same problem and actually broke my phones mini usb plug in frustration at lack of charging. Got it fixed again though
The reason for this problem has become apparent since my phone was repaired. In your car, like my car when the heater is switched on it will gradually heat up the cigarette lighter socket. My charger cable like yours has a thermal safety circuit built into it. So when the ciggy socket heats up the heat is transferred to the charger plug and breaks the elec charging circuit. You might see me driving around London with my charger plug hanging out of my window (to cool it down) on a Winter's day!!! Honk if you do.
The solution would be a cheaper charger without the thermal circuit built in. Go into Maplins or PC World and ask them for that..... They dont know what your talking about, because I have already tried.......! Good luck
You just need to make sure to enable your phone to charge when connected to PC.

hi there.
shortly-i have this phone with no orig. usb cable and with no wall charger. it was friend of mine phone actualy. given to me with dead battery (i am not sure but i have trouwn it away long time ago)
first I did was to wait until friends of mine from china had sent to me 2 batteries compitable with the phone. what i discovered is that a normal ordinar usb cable cant charge the phone's battery it only can connect to the pc.
second what i did is this: i found my old charger from a very old panasonic cell phone and had a try to make the charging process with the simply contacting corresponding pinouts of the battery to the +&- of this same charger (somehow i dissasembled the plug of that charger and it became more "comfortable" to get in touch to the pinouts of the specific cingular's battery)
that unordinar way i did discovered that i can charge these batteries even not sure how much appropriate that other brand wall charger is. It seems its pretty much the same as a power characteristics.
Meanwhile (as i dont use this phone) i had some free time to search the net and to have better idea about that strange unordinar power charging matter with that model of a phone. The situation is that i cant find a place nearby me to buy a cheap usb and wall charger and become using this nice device finaly.
And also i dont want to buy these cable things before clearly understand why this happens ..
I did try also to charge this phone with a HTC brand wall charger but no sucsess again cause it seems this wall charger is for other htc phone (even same mini usb plug and same characteristics)
What i need is to have answers by someone very informed about that matter and let me know what exactly is the specific power charging matter (need explanations i mean) with this phone. If sharing some good ideas about how to remake others usb cable or wall charger for geting it work along for me in such a case , i will appreciate this very much
thanks
charge
hi ! please forgive me for my bad english! in this case you can charge your phone in 1 way! you need to procure a motorola or any charger with same socket but attention the charger must have 6 volts and no less than 500 mAh(milli amps)! you cut the wires and one wire put on the + of the battery you will see the signs on the battery an one wire at the - no matter which one. and you need stay with the wires 3 - 4 minutes on the battery ! then you put the battery on the phone it will start and then you cand fully charge it with the usb cable ! good luckk ! i hope my inf will help you!
no
no it doesnt work that way.
what i need is the simple answer : what is so special into the pinouts of htc cingular 8125 wall charger?
thats what i need only. Then I might figure out how to proceed
Thanks anyway
I don't know if anyone else has had trouble doing what I have done, but I've got the Cingular 8125 (HTC Wizard 100), which is also known as the HTC 8125.
1. I bought a car charger at a convenience store for $6 that had the mini-USB plug. It worked like a charm. Never any problem there.
2. I also bought a standard USB to mini-USB cable from the local computer store, because I had lost mine, and it also worked fine for both synchronization and for charging.
3. I bought a second wall charger, buying a standard mini-USB wall charger sold pretty much everywhere cellular phone chargers are sold. It's a common charging port, and this generic worked for me as well.
I'd be interested to hear if anyone has had problems with these types of devices not properly charging the unit.
Even my USB cable for my portable USB hard drive will power my unit.
EDIT: About your problem with it not charging. I had that problem about a year ago, when my battery got extremely old. It wouldn't charge even with the original charger. I just needed a new battery. The batteries get old and stop taking a charge after a certain amount of use. How long this takes depends on how heavily the batteries are used. They, like car batteries, do not last forever.
I had this problem when I had my wiz too. The battery died and drained, and my phone refused to charge it. I took it to an AT&T service center, and they had no clue what the problem was, and they wanted to issue me a replacement (it was a G4, I had a G3, I wasn't about to fiddle with that at the time.) So I asked to borrow a demo device they had there to fix it. I charged my battery on their demo device no problem, got it up to 3%, and finished charging it through my USB cable in the car socket.
It appears to be a sort of one-in-every-few-or-so type condition, but I got hit with it.
seems like noone can tell me if something special inside the mini-USB plug.
i realy cant charge. Very nice device, but i cant make it charging up whit cables.
guys, from up there, say that nothing special about the charging cables, but i trust what i see not what i read.
Perhaps there is a problem with your USB port on the device? USB charging has standards, and all devices that need power from a USB port have the same power pin configuration. Otherwise, they can't call it a USB connection. It would have to be called a proprietary connection, and they would have to change the plug size/dimensions and pins.
If there isn't a problem with your battery (which is the most likely source of your problem), then it may be a loose connection on your USB connector. This happens with a number of devices.
If a sync cable connects to the PC but will not charge the battery, then you definitely have an unusual pin detachment of some sort, or a bad battery.
thanks again..
for pity i was writing a lot to make my recent post and finaly it desapeared cause my session was left.. its funny in some case, but now i just dont want to repeat all what was intended to be posted
i give only the link where you might see why i was assuming that this is a kind of a special matter here with that htc 8125 charging

so, any more help will be appreciated a lot

Hi - Too bad for the OP that asked questions but did not listen to this brilliant post.
I have confirmed that a variation of this method works perfectly! I have an old Cingular 8125 that I have been trying to charge for over a year using various USB chargers and NONE would charge the device.
The reason that this may happen is that the original charger has an output of 1 full amp which is much higher than most chargers. The voltage is the same but you need a charger that can handle such a strong current draw.
Nearly all USB chargers can only handle around 250milliamps - 500milliamps which is about half the power needed to breathe life into a fully discharged battery.
The best solution is to NEVER let the battery fully discharge.
Here are the details of what I did:
1. Find the best match charger of 5-6 DC Volts and ability to put out as close to one amp (1000mA) as possible. I chose an old Sanyo SCP-07ADT that is rated at DC 5.4V at 800mA. The plug can be any type, no need to be USB.
2. Cut the connector off the end of the cable and strip the outer black part up about an inch and then strip the positive and negative (red / black respectively) wires up about a millimeter, just enough to have bare metal ends to touch to a small area.
3. Take your battery out of the phone, look at the back of battery for the + and - marks which correlate to one of the metal connection points on your battery, this is where you will "touch" or "attach" the bare ends of the wires.
4. Plug the charger in making sure not to short your bare leads. Before you do this double check that the OUTPUT of your charger is indeed DC voltage so that you don't hurt yourself. You do not want AC output and it can be dangerous.
Then touch the bare end of the red wire to positive of battery, and black wire to negative terminal of your battery. I held them with my fingers while surfing the web for about five or ten minutes. I had no idea if anything was happening or not but it "felt" like the battery might have gotten just a bit warmer.
5. Unplug the home-made bare wire charger and put battery in your phone. Quickly attach a USB charger or just plug into a USB cable of your computer. I pushed it in and nothing happened at first but finally I heard the standard "bleep" when you plug a USB device in. I knew that I made progress because it never beeped before it took about 30 seconds and several "bleeps" of connecting/disconnecting from USB but eventually the charge light stayed on!
It's been about 30 minutes and I'm up to about 50% charge and been using the phone heavily while charging.
So, in summary... never let your battery discharge below 5% or you can only charge it with an OEM cable rated at 1amp (rare). IF you let it discharge to "dead" then charge for 5-10 minutes with the "wire" method and then charge normally!
Thanks to Dozzen for the original idea!!
Wizard that won't charge
When my Wizard/HTC 8125 goes dead my cure for the battery is to use a 9 volt charger with the wires stripped back also. But, my method is a bit different. I place a standard Christmas Tree light bulb (the newer small ones)in series with the charger wires. Observe the correct polarity. The battery is labeled + and - so that part is easy. By using the small light bulb you are doing 2 things. 1.You can see the slight glow from the bulb and know that proper connection is made. 2. You are limiting the charging current to the battery.
If you get really creative like I did you can solder a couple of small nails or in my case a set of red and black probes to the setup and the points on these nails/probes make for much easier connections. Note.... This method may take a few minutes longer but, is much easier on the battery.
In my experience once the battery is below a certain level NO charger that I plug in will work. I just purchased a used 8125 from eBay and brought it back to life most successfully with this method.
hy there my htc wizard battery whos dead so i charched with a cable with + and - the phone starts but when i try to connect to a usb or a adaptor it doesnt charge anymore it show me the charge icon on the baterry but it doesnt charge the usb works fine it's sync to my pc but it doesnt charge anymore... what sould i do?
So it seems no one touched on what really matters here.
A design flaw, in my opinion. The HTC Wizard cannot recharge via USB unless there is enough power to turn on. The reason is because it requires the OS to charge.
So, what many people already posted are very creative ways to charge your 8125. The easiest and cheapest way, in my opinion, is to use AA batteries.
1) Take two AA batteries and tape together so they are in series. Imagine it like this... [- AA battery #1 +][- AA battery #2 +]
2) Use two wires and tape one to each side of the AA's (one on the + side and another on the other battery's - side since the - of the first battery is connected to the + of the second).
--w-i-r-e--[- AA battery #1 +][- AA battery #2 +]--w-i-r-e--
3) Connect the positive (+) wire to the positive (+) side of the phone. By this I mean the 6 metal pieces that stick out to contact the phone battery. I did it by wrapping the wire around the top most one (or second top most, it's been over a year since I've done this.).
4) Connect the negative (-) wire to the negative (-) side of the phone. Again, bottom most or second bottom most (see #3).
5) Insert phone battery while the wires are still in and connected to the two AAs.
6) Let the power flow for 30 seconds or so and then try turning your phone on. This part is the important part because you cannot use a USB to mini-USB connected to your computer to charge the phone unless the operating system can function. Meaning, it needs to be turned on first.
7) Once the phone is on, plug in the mini-USB part and connect it to a computer. I'd recommend getting at least 5% battery before disconnecting the AAs, seeing as you need to be able to start up your phone long enough for the OS to boot. Once the OS boots, you can fully charge it through a normal USB to mini-USB connection on any computer.
old post but just wanted to say thanks. Used the wire to battery method and got phone turned on after 2 mins of holding wires to battery.
