faulty XDA 2 - MDA II, XDA II, 2060 General

Hi, Can anyone help?
I plugged my XDA 2 into my home pc's USB port using its cradle. I noticed it began to over heat, now the the top righthand power recharge light stays on (active) all the time even when it is not in its cradle, in addition to this that battery dies very very quickly e.g 15mins.
I have not been able to find any fault codes relating to the yellow light ( this should normally show only when the phone is charging.) I have tried updating the ROM and also a new battery but the problem remains.
I'd be really gratful for some advice.
thx

If it overheated it is either a short on the cradle, a short in the pda connector, a short in the battery or too much voltage. I would suspect the first three, sounds like the battery is now cooked. This is a warranty issue I think.

Do you think I could repair this my self maybe a blewn fuse or somthing ?

Repair a Hermes

All,
I'm looking for a company which is able to clean and repair my HERM300 device.
It got wet and now when I want to charge it the led turns red.....
When I leave my device on a warm radiator it works and I can use the device...
But it seems to fail when it gets colder....
Any suggestions?
Cheers and thanks,
Hellejoep

Can you say a bit more on "fail when it gets colder...."
I ask because soon maybe tonight I'm going to make a post on the charging and Red light problem but I'm just wondering exactly what you mean by "fail"

It blacks out as soon as I connect it to my activesync via USB....
Is it a short circuit?
Or something else?

I would like to add something, may be you already know, to red led knowledge. I have a car charger (just plain chinese USB charger with usb cable) When I connect my HERMES I could have 3 conditions: orange (charging) Nothing (not charging) or RED (?). If I soft reset, with charger connected, I ALWAYS have orange, after Windows Mobile screen, But if I disconnect and reconect I have ALWAYS No Light
connecting hermes to charger without battery also enables red light.
Charging Problems - Red Light of Death (RLOD)
Battery Charging Problems, in particular the RLOD so called because the phone refuses to charge and the red LED shows, indicating that the battery is NOT charging.
Background
Problems with charging are not HTC or Windows Mobile specific. Similar if not identical problems are reported across many models and platforms. The issues centre around the state of charge of the battery and the interpretive circuitry in the device and charger. Typically a device will show a Red light rather than an Amber charging light. (NB: RED LED always shows when battery is absent or fails to charge). see also http://forum.xda-developers.com/showpost.php?p=1076879&postcount=28
Getting the battery to start charging once this light is shown is not always straightforward and is as unpredictable and temperamental as priming a water pump (those that have done this will know what is meant). In other words, and to put it crudely, you need to kick start the system. Unfortunately those that have managed to do this have usually tried lots of things before it starts working again. This makes it hard to be absolutely certain about the solution other than perhaps the last 4 or 5 actions taken.
Those that have managed to recommence charging have not reported that the problem recurs on a frequent basis. (possible exception of in-car charging issue). This issue requires patience and time, (time maybe critical, it is possible the issue would resolve itself perhaps as charges dissipate within battery and circuitry involved). However the following points seem probable solutions and were thought to work by some who resolved the problem.
Failure to Charge (Red LED Lit when charger connected)
Causes of this problem are unclear, but in practical terms events leading up to this issue have included:
1
Leaving the phone on charge overnight (possibly but not necessarily with certain programmes or connections running) It seems a fault occurs in the charging system, which causes the battery charge to drain rather than increase. Resulting battery charge is very low. (Another Blog will be added concerning an Active Sync issue which can cause the battery to drain over-night through repeated connection attempts)
2
Through heavy use or not re-charging often enough so that the battery is permitted to reach a sub 10% charge (not precisely known but likely to be very low)
Possible Solutions:
A
1.) Remove battery
2.) Connect the phone to the charger or USB
3.) Insert the battery while connected to charger
4.) Red light should turn Amber
5.) Soft Reset
If this does not work immediately it is suggested that the battery be removed from the phone for around 1 hour and the above steps repeated.
OR
B
It has been found with some phones charging can be re-started by:
1 ) Remove battery
2 ) Connect charger (Optional. I would try this potential solution without the charger connected the first time I try this. If it fails to work then I would repeat the steps with the charger connected)
3 ) Holding the battery, line it up wiith the phone's battery contacts.
4 ) Move the battery rapidly on and off the contacts
6 ) Repeat the above until the Amber charging light comes on. So after perhaps connecting/disconnecting 20 times, insert the battery properly and give it a few seconds to see if the LED turns Amber.
7.) Soft Reset
NB: I have seen two reports where those attempting this report a fairly loud "pop" sound following which the phone began to charge. However in one case the person reported that they then had subsequent problems of signal reception on the phone and thought the popping sound may have been related to this.
OR
C
If your problems remain after trying this a few times you could always try the following to manually charge the battery a little (enough to let the phone charger circuit detect the battery is present when you put it back in)
1) Remove the battery from the phone!
2) Take 3 fresh AAA batteries in series (total 3 x 1.5V = 4.5V)
3) Connected the (+) wire to (+) on the battery
4) Connected the (-) wire to (-) on the battery
5) Hold this in place for 60 seconds.(possibly longer you are trying to charge it enough for charging circuitry to recognise there is a battery installed.
6) Put the battery in your phone
7) Switch on phone and start charging (via USB)
Hopefully you will get the Amber charging light.It may be worth repeating this a few times if not successful on the first try.
The electrical contacts are all important, poor contacts will render this a worthless exercise.
I leave it to you to decide how you connect the wires. If you have no other means you could enlist the help of someone to hold the batteries and wires together while you connect to the phone battery! Warning - Do not connect a mains based transformer to the battery with an incorrect charge rate (mAh) and voltage (V). Any attempt to force charge using mains transformers could be extremely hazardous (explosive). Only a qualified/competent person should attempt to charge the battery in this way. Similarly, even if you are using batteries to do this task, do not leave them connected for more than a few minutes and stop immediately if either set of batteries become warm.If the problem persists:The final resort - a new battery.

Very good article Mike, I linked it on the Hermes problems wiki page
i just want to add my 2 cents to this, there was an earlier post on here that mentioned the car charger deal where it wont charge unless you turn the phone off, plug it in, then turn the phone.. right now i am on my 2nd 8525 and it has done this, but its not only the car charger (cheap belkin car charger) but it sometimes does this with usb cradle i got from ebay, i have opened the cradle and there isnt anything different, its a straight usb connection, hmm except now that i think about it there is a blue LED, but it shouldnt be drawing enough current to cause this. Also i have a motorola charger in my office that i used with my wizard (i believe output is slightly different, if i remember correctly its a .5 amp where as the HTC charger is 1 amp) but it also behaves in the same manner... the only 2 methods that work constantly and consistantly of plugging in without turning off is either the factory charger, or a regular usb cable on the pc..
just seems weird since all of these problematic situations worked fine on the wizard and i believe they both have the power requirements...
let me toss another idea in the fire here on this, something that just occured to me... i wonder if this somehow could be related to the factory installed driver for this. what made me think of this is how the battery meter only goes by 10%.. could this funky driver be the source of the problem?

If your cradle is not connected to your PC, or if your PC is off while you see the behaviour you described, then the likely reason is that pin 4 of the Mini USB connector isn't grounded on both your car charger and cradle. See here for more details.

Some of the type sizes are a bit strange (but readable!) serves me right for copying and pasting from Word formatting!
Tadzio's link is good/informative and I edited in a link to it in my post - though it's on this page anyway.

cradle is connected to pc at all times, and i will deal with the car charger for now cause my HTC one should be arriving any week now, but thanks for the tip!
8525 (hermes) Charging may be voltage sensitive
I have noticed with my new 8525 (USA Cingular model of phone) that it came with a 5.5V charger. Whenever I connect to a 5.0 V USB source charging the phone is very "iffy". Given that the standard for USB is 5.0 V (4.75 - 5.25) there is a problem with the design. My question for the HTC crowd is can this be fixed via a ROM change or are we stuck with a bad design?

Since you got it wet, it is most likely not covered by the warranty, these and the numbers for out of warranty repair if you live in the U.S. I know that for cingular, you have to ship it to them yourself, and they will charge you a $28 diagnostic fee, before telling you how much is costs to fix the problem (if they even can)
heh here almost the same, providers are charging ~$29.5 USD as diagnostic fee but they are more polite, they first tell estimated costs, and only ask for the sum if you (usually) don't order the repair but need back your phone
Hellejoep:
if you are willing to send it abroad (inside EU) and you are either not need "overnight return" or such nonsense or cover the extra costs such operations really need, you may contact me. no diagnostics fee or anything such (though you will have a small loss.
about the charging problem:
the same issue occurs also in Wizard/Prophet, and Charmer (compactII) as well. though not in Magician, even so that they share the exactly same battery.
I believe it must have something to do with the charging controller. I don't have a disassembled unit at home with me now, but I suppose it should be a crap companion chip from Texas, to be interfaced with the ever-worst TI OMAP platform
(sorry, no hard feelings, pals, but someone using such one as an actual everyday phone must have some sorta mental problem )
strange battery issue
Hi all,
I've a similar issue with any charger.
It happened first with car charger (one cradle with an usb output): sometimes it charged, most of all it charged only when power was off.
Now I cannot charge with any method. (those described here: battery charging problems)
Usb cable (it's not original), original power supply, even with the y cable.
When i try to charge, it drain battery (i tried with a new one) and amber led blinks slowly instead to be firmly light.
There's anything I can do?
It's a SPV M3100 buyed two months ago on ebay.
I tried also with two roms WM6 official release ITA ver and Schap's 3.54b ITA ROM WM6

Any suggestions?
Herm200/tytn problems
hi to all,
i read most of your post on possible problems with this PDA (HERM200/HTC TYTN).
i'll try to spent some few words to explain the story around my pda.
i live in italy and i bought the TYTN on december 2006 and for 6 months with his software problems i used it day by day in my business activity, untill one day, it falled down the ground from my and with all the leather cover (bundled with the pda, an hard black belt cover); then i took it and picked up a telephone number from my addres book and then putted it in charge for all the night; when, late in the morning, i took it, i noted that there was still the red light of the battery indicator and then PDA didn't turned on.
i tried to make soft/hard reset but nothing.
I carried to the italian warranty service of HTC and after 7 days they deliver to me the PDA in the same state that i carried; on the technical report there was: pcb damaged, battery connector pinouts damaged, pda not Repairable - out of warranty.
i thought: "i have had a lot of care for this PDA that still look like as new one"
and now i have a 700€ of unusefull PDA.
Last day i finally decided to open my PDA to find broken pieces and more.... but nothing.... i observed really well: NOTHING of wrong.
Now i will to know if somebody of you, can suggest me something to revive my PDA or suggest me any service center (affidable) in europe (not like the italian one) where to send it for maintenance: I DONT WANT TO THROW OUT MY PDA!
Thank you in advance for your attention and patience.
ps: sorry for my english, i hope it will be comprehensive.

If I understood you correctly, your TyTN still works - it just cannot charge the battery, right?
Then, probably one of the cheapest (although not perfect) solutions is to get a cradle that can charge a battery outside the TyTN (like this one on eBay). You will have to power down your TyTN, remove the battery and put it in the cradle every other night or so, so it's not very convenient. But it's cheap. Maybe you'll want to keep this as "plan B" in your mind while you look for a more perfect solution.

Hello!
I had also a battery charging problems with my MDA Vario II (TyTN; Hermes; HERM300):
1. Charging from the AC mains supply with the original miniUSB 5V charger: no problems.
2. Charging in the car with the non-original car lighter miniUSB 5V charger: it was charged only when the phone was OFF; no charging when the phone was ON.
3. Charging with the USB-miniUSB 5V cable connected to the notebook: it is charging only when the phone is OFF; no charging when the phone is ON.
So I asked myself: what is the difference between all these three cases? They are all miniUSB 5V power sources... And I found out an answer: It should be a matter of the USB current amperage.
Original AC miniUSB 5V charger delivered with the phone is 5V/ 1A. When I have bought the car 5V miniUSB charger with the 1A (one amper) amperage - there is no problem with car battery charging anymore... ;-) The phone is charged either way: ON or OFF.
But is it possible to charge the battery correctly from the notebook? I think not, because I have no influence on the current value from the 5V notebook USB.
Previously I had MDA Vario (Wizard): in this phone there were no battery charging problems... I wonder why the are some with the Hermes...
Take care,

This is not correct. The problem is well understood and has been discussed several times.
The key is that your device tries to sense what it is connected to:
- if there is USB data traffic, it concludes that it is connected to a computer. It will then negotiate the current (power) it can draw from the USB port with that computer.
- otherwise, your device checks if pin 4 of the connector is pulled to ground. If yes, it concludes that is is connected to a dedicated USB charger, and starts charging, consuming as much power as it needs. This mechanism seems to work only if the device is on - and sometimes not even then (bug?). I guess the mechanism is implemented in software, so it can't function when it is off.
- otherwise, it doesn't know what it's connected to. Could be a computer in stand-by that didn't power off its USB ports or something. Your device concludes it may be unwise to start charging (could, for example, drain the other device's battery).
The cheap after-market chargers do not connect pin 4 to ground (pin 5), so your device doesn't charge. If you are really good with a soldering iron, try connecting pins 4 and 5 of the charger's USB connector, and you'll see that your device will start charging with it.

Thank youu Tadzio,
but my PDA is DEAD !
I still don't try to charge the battery separetly.
The reason is that when i carried the PDA to service i leaved the PDA and Battery: i dont wanto to believe that service dont check the battery !??!?
However , i will try to charge the battery separetly and then i will know you the outcome.
Thanx and Cheers

Help! Jamin not charging and showing red light

Hi all,
I have no clue about what i did to my Jamin but even though it has
been pluged-in to my pc all day, the battery went down to zero. Now i
cant even open it. I am now using a charger to charge it. However, it
now shows a red light (not orange) and still not opening. I cant see
anylights on when i plug it in to my pc either.
I tried to look at the meaning of the red light on the internet. I
guess it means "device not charging". What do you think is the problem
and can anyone suggest anything????
Thanks in case
Hi,
I had a similar (not same) problem on my xda neo: no action at all even after long loading (NO LED, not even red). I finally resolved it by manually loading the battery (upper contact = plus, lower=minus, 100mA feed current, 3,9 V shutoff voltage, 4 hours at a laboratory power supply) - for me that helped.
It seems, the device does not have a charging logic which works just from USB power - it seems however, the device needs some battery power to get the charging system up and running - very silly!
If you do not have access to a laboratory power supply, but know someone else with a working PDA - just try to swap batteries to see, whether the problem sticks to the device or the battery...
Question from my end to everyone: "manually" fiddeling with teh batteries ist really ugly - is there anywhere a charger (other than the PDA itself) for the PM16A?
Regards

Charge with a RC Car Charger like Graupner Ultimat10 ... it can charge a ILPO without blasting the Akku :->

HTC TyTN does not charge anymore.... Need Help

Hi Guys
I have a problem with my TyTN at the moment.
My device is not charging.
Yesterday i put it in my Docking Station and wait a little time.
But Now the Tynt isnt charged.
I think ist a Problem with my TyTN Hardware.
I have all Power Supplys used they i have, but it doesent work.
Can you help me?
Its this a problem with the accu or a fuse on the circuit ?
Sorry for my broken english i hope you understand me.
Regards Patrik Laube
Hello,
first of all, try to soft reset the device.
If it fails, hard reset it.
If it doesn't work, go the service center.
Good luck
The above advice is fine. But you did not say if any of the LEDs are lit.
Do you get the red NO CHARGE LED?
Does your phone operate normally except for not charging?
Mike
Hello
My Phone is working fine but i cant charge it with the original HTC adapter.
I must load the accu with a special loader.
USB and Charge dont work....
And i have no warranty I cant send it to my operator.
When i plug in the USB Cable it doesent make everthing.
I think it was a to high voltage on the USB or the USB Ground ( - ) had a electrical Power for a litte moment.
Have you an idea?
Thanks for yur help.
Regards Patrik
I had a similar problem, which was sorted by a new rom, but I ascertained it was software problem when I realised it charged when powered off.

hi,
try this: when your device is connected via usb, tab on the battery icon in the taskbar on you device, go to the register "advanced" and check/uncheck "When Device is turned on, do not charge the battery when connected to the pc"
thats it

I'm having an issue along these lines, also.
My phone has been working fine untill the other night when I tried to charge it via the wall electrical outlet. It will not charge at all, the battery has been drained to nothing and I can't turn it on. The yellowish light doesn't turn on when I plug it in like it used to.
I don't know if this is a battery issue or an issue with the USB connection inside of the phone. On a side note, when it did have power and I tried to connect it to the USB via the PC; it didn't work. The phone was on, but the computer didn't even notice the phone was plugged in. That leads me to believe it would be a connection issue; but I'm not quite sure.
If anyone has anything they can add to this I would appreciate it, thank you.
P.S. Bringing it to a service center is a bit out of the question in the mean time seeing as it was bought on eBay and funds are limited for the time-being.

Hello, I cannot find the "When Device is turned on, do not charge the battery when connected to the pc" in my device. My Rom is WM6.1 CE OS 5.2.20273 cooked by dvha79_ddt.
My HTC TyTN has the sample problem, but i can use the USB to charge normally. It cannot work using my AC adapter Only when the device is open...
About your Battery Issue.
I'll tell you exactly why ur phone isnt charging anymore... If you have been charging it alot on the USB or pretty much any!! charging on the USB u have killed ur battery, never charge your phone on the USB it kinda sucks they should make these phones able to be Sync'd thru USB without a battery cause these batteries should not be powered thru the USB over Time... from syncing to your pc will kill these batteries i have noticed that when u sync this Tytn Ithru USB and the device is at say 70% it charges up to 100% pretty fast i would recommand to you and anyone who reads this dont sync your TYTN or any HTCC phone for to long to the USB Cause it will Trash your batteries Life down the road... Hope this was HELPFUL.

^I'm having the same problem with my herm200. I did the soft reset, hard reset changed ROMs but still the same problem. I don't think it's the usb connector because if it is it wouldn't have been able to charge the phone even if it's turned off. Before I'm able to charge it turned on but it would take a few minutes before the orange led turns on, but when I use the phone or if I receive a text the orange led would turn off it's like the charger disconnects but after a few minutes it would go back again. Now it just wouldn't charge turned on, sometimes it gets worse where it just wouldn't charge on or off.
Now I'm already planning to buy an external battery charger.

Are you using an official 1000mA charger? (Not a 500mA one) 500mA ones work, but they are under-powered and can cause strange behaviour, like not charging whilst turned on or whilst on a call. Similar problems can be found with car-chargers that will not charge until the device is soft reset.
Mike
^no it's not the official charger, I have this usb wall charger called Power Juice (phone and mp3 charger).
Input Voltage: AC100-240V
Output Voltage: 5V
Output Current:1000mAh
Do you think it's because I'm not using the original charger?
fixed my charging problems
The boyfriend told me to try a new cable for my charger so he bought me a 5pin usb cable, tried it at home and it worked! I still need to turn off the screen sometimes but that's ok at least I don't have to turn off the phone anymore. Now my battery charges less than 3 hours.
Hold both SoftKeys and Then press the Power button
Or you can also hold both softkeys and then put your stylus into the reset hole.
answer why it does not charge through the usb
Sorry for the very very late response. Under electrical legislation all hand held electrical devices must be insulated and fused. Some of the chargers that you can purchase are sealed without fuse which indicates that the phone has a fuse contained within its circuitry (or there may be 2 fuses one in each device) .
The problem you have encountered is that you have connected your phone to a computer or mains supply to charge. There has been a surge in the electrical supply either on connection or by un-connecting from these supplies (e.g. connect to the computer as it is booting would see a 65w signal through the USB) and this more often than not blows the fuse which sits on the PCB (printed circuit board) just after the usb connection internally to the phone.
you can either have the fuse fixed for 20/25 gbp or you can purchase a new circuit board or you can use an external charger for the battery. As it is only the power input point that is faulty.
hope this helps
Since we are at this non-charging & battery issue, I would like to ask this question on the D838pro. My battery won't charge even after 24 hours of charging. The red LED blinks thru the whole process. The LED did not turn on to orange or green. It is the battery problem because my spare battery works well. I would like to know what is wrong with the battery as I am willing to strip down the battery. Could it be the battery circuit or wiring that had fired?

I would like to know what is wrong with the battery as I am willing to strip down the battery. Could it be the battery circuit or wiring that had fired?

Never tried stripping down a battery, some things... well, just don't seem worth it. However as a learning exercise it might be interesting. Without lots of testing on a good battery with a multimeter then I have no clue what the readings should be between all the contacts. (Now there's a little job for you) It is as likely the internal structure of the battery is screwed as it is to be a wiring problem.
If you solve it you can certainly report back here

charging problems

Hi guys asked it once before in battery section, but no replies.
My HD doesn't charge auto, when I press the on button the battery charges for 15 sec. tried a new battery same result. I know it Physicly charges, when I charge the phone by pressing the on button a couple of 100 times (really 100x) I get 1% charge. So don't say 'HTC phones only charge when on', cause I know.. Tried a Hard reset 2 times no luck. meanwhile my batt. is dead. So I can't try other firmware.(need 50% charge min)
(chargers are fine)
In short, anybody ever heard of this problem before with other htc models/HD ?
Physicly it charges, so would a firmware change help?(then I need to get a standalone charger/new battery with charge).
My last option is to bring it to HTC but that would take a month
Sorry for number of words on this lazy sunday.
Update - firmware update doesn't work.. next is radio....
no ideas anybody?
Hi,
Unfortunately I dont know much other, then charge the battery in another HD up if available (maybe u can ask in a telephoneshop or so) and then test the Firmware changes.
Is the same if you charge it via PC/USB?
thx for the reply, did just that, changed Rom/radio, official and dutty's rom's, no change. No problem sync. have atleast 3 usb chargers none of them work. When connected to usb cable 2 lights blink 1 green 1 amber one after each other. just like a new message/ low battery even when battery has 50% I get the same light patern, (this is a new battery).
The thing is when the battery is completly flat it stil charges for 15 sec then it turns of. So when I charge it 15 (x15 sec) times or so I'm able to turn the device on again. But when it has (some) battery power the lights start blinking again and I'm completly unable to charge the battery.
The phone is almost 2 weeks old and charged normaly until I checked the "don't charge when connected to usb" option in the power menu. ??!
Then I think you wont get around, to send it back for repair.
have you tried to charge it with a wall socket or is this only when you usb to pc charge??

I never charges, wall/usb doesn't matter.
I just used another HD battery to restore everything to default, So I'll guess I'm taking it back..
Thx anyway.
exact same problem
Did you get anywhere with this problem? I have been strugling with the exact same thing... I have tried all the same things as you, only sometimes it seems like it might be the battery contacts.. I havent been able to consistently get it to work but sometimes if I firmly press the battery against the contacts it will behave normally

Nope tried the contacts but they work fine, battery just won't charge, do your light also blink? (on the power button).
I haven't found any info on the web?!?:S
Problem is solved.. had to be sent back to HTC for repair, it took less then 2 weeks (door to door) so that was pretty fast. They swapped the mainbord, so I got my 'old' phone with a new imei.
So don't waste your time with software up/downgrades. It's a hardware problem.
I had a very similar problem.
Once my battery died some app hung system all night.
No charging at all wall charger and USB 1 day each and so many manipulations. The indicator blinks momentarily and then nothing. I didn't try (didn't know) the key presses like Dogtag. Did a hard reset still nothing...
Then thought about charging the battery with external (Lion) charger before sending for repair. I also shorted the battery compartment pins momentarily. To my pleasant surprise everything back to normal
So far no problems after that though I never drained my battery to zero.
Looks like something to do with corruption in battery calibration data - may not be in ROM?? who knows??
fantastic. can u elaberate?
hey Cragee
I did't understand what u did. Can u try to explane it to me one more time?
I'm realy excited about a posible soulution
hooray

Only two things I did can matter -
1. Charging the battery after taking it out (with a battery charger*)
2. shorting pins in the battery compartment after taking out the battery. (Warning: not on batteries)
Don't know which of the two worked.. No harm trying both anyway.
* U need a Li-ion battery charger - else invitation for trouble including fire and explosion.. These are available in electronics shop at a reasonable price.
Short-circuiting the battery pins... seems to work
I had the same problems with my Touch HD the last few weeks:
- stopped charging after a few seconds
- didn't charge at all (nor the wall nor the computer method, on or off)
- well... it charged sometimes but randomly, keeping it on a wall charger (on OR off) for a night could bring it back to 20% and then rapidly back to 0%
- no charging indicator in the screen while turned on
- blinking orange and yellow (?) light even while turned off
- charged almost never to full and 'jumping' from high to ultra low capacity when turning it on & off
So before bringing it back to the store i tried to short circuit the battery pins as suggested (while the battery and charge were unhooked) like the thing you would do to clear the CMOS memmory of a PC in the 'old days'
And for now it seems to work, at least the charging icon is back online!
I'll keep you posted on longer term results!
Update: I switched to the wall charger and the HD died again??? Now it's back on the computer and it seems to charge fine... why????

When u say "shorted the battery" do u mean, turnoing phone off, taking battery out, connecting the 3 battery connectors with a wire for a few seconds?
....so what does shorting mean??

I thing so. You should circuit the pins WITHOUT battery. In any other case it may occurs damage on the telephone
Dogtag is right... it's defenitly a hardware problem
As posted before...i had the same problem with my touch HD, charging was a pain or sometimes seemed impossible. The phone was repaired twice.
-First they replaced the connector - no succes.
-Second time the replaced the motherboard, and everything was solved.
So imho it's the mainboard of some machines, i still wonder if it's a factory problem or a 'fried' chip of some kind after a bad charging procedure? Bad USB car charger of some kind?

Atom life only recharges when turned off

Hello,
my problem is strange.
When I turn off my Atom Life it can be charged (USB, External Power Supply).
Red indicator light on.
When turned on (in use) it does not charge. The charging symbol in the status line shows the unit is connected to external power, but the red indicator light is off, and power continuously goes down.
I already tried a hard reset, but that did not help.
Does anybody have an idea?
Sorry, I forgot to mention that everything with charging went fine earlier (until some weeks ago)
charging
same thing with my XDA ATom dude
I have ordered a new battery for mine at ebay (did not arrive yet).
Maybe it helps.
Otherwise ...
Ok, the battery came in and it does not change anything.
Still the same issue.
So I am gonna litter it...
bye bye
New info,
there seems to be a bad contact at the USB connector.
If I connect the USB cable and hold the plug in a specific angle, then the charging light (red led) turns on).
Brought the device to a friend of mine. He's good at electronics and tries to figure out and fix the usb connector.
wait and see

any news for your problem ??
i'm having this problem too
i brought used one and seems the battery is almost dead and can't charge when device is ON
Thanks!
I got a used atom life and bought a new main battery for it. Charging via USB cable connected to my notebook is working fine. Using the (wall socket plugin) power supply with the same cable it behaves the same way you described it. It starts charging only when the device is turned On and back Off. In my opinion the power supply is the reason. Maybe it is to week ar has some sort of security switch build in, which is protecting it against to high power consumption.
In my case it was definitely not the charger. I tried several ones and they behaved all the same (the original one wrked for long time).
It is the device itself.
I had it sent to a friend who was able to open it and a have a look at it.
The USB plug itself was a bit loose. But soldering it again did not fix the problem.
There seems to be a micro break of a wire on the mainboard (which is multi layered). So no real chance to repair.
I replaced my device by a HTC Desire which was available in Germany very very cheaply (you don't want to know the price because it wuld be too frustrating).
So goodbye Atom Life.
