MDA 2 battery charges on USB but doesn't on standard adapter - MDA, XDA, 1010 General

I have been using my MDA2 without problems for over a year now. Recently it developed a problem. I noticed that when I put the MDA in the cradle it only charged the battery (green light on) when the computer was on and USB connector was attached to the computer. Although the adapter was also attached, it wouldn't charge the battery anymore when the computer was off. The same problem occurs in my car. When I put the MDA in the car-loader, it doesn't charge anymore.
I think the connector might have a loose contact or so. Can anyone help with this problem? Is USB charging different from standard (adapter) charging? Different voltage? Anyone heard of loose contacts in the connector in the mda? I tried different cradles and a new car connector but nothing helps. Anyone?

Car charger not working anymore used previously with 9100

Hello,
I've got my TyTN in europe (ROM 1.18.256.104) and my "usb" car charger is not working (charge sometime but ONLY if my TyTn is switched off....not usefull for GPS...)
I've tried another one same problem...restested with my 9100 : ok .
Is it due to the charging load ???
Anyone experiencing the same problem ???
Cheers
André
If I remember correctly the 9100 used an 800mA charger and the TyTn uses a 1A charger. That could be your problem.
hello,
same problem, but charging work on laptop (normally laptop is unable to offer more than 500ma).
I've read an article with C500 where charging work when pin 4 of the usb cable was linked with gnd. Is the same problem with Tytn ?
cheers
Tom
yep, had the same problem too with a standard charger with usb cable.
the charger output was 500mA. it stopped charging after a few seconds.
Recently i bought a Brodit carholder with the charger included. This charger has 1000mA output and its charging without problems.
So you need at least a 1000mA(1A) charger, otherwise it will not work well.

Thanks Luminus for the Reply, But are you sure there is no electronic part added on this car charger ? :?
Strange enough, both my car charger and USB Mains adapter (1A output) (which I was using for O2 Mini and Dopod 818Pro without any problem) was charging fine on my Dopod 838Pro, but the unit had a problem and I was given a new unit. This unit now does not work with my car charger nor the USB Mains adapter.
Looks like a trip down to the service centre again!
it was a cigarettelighterplug adaper with a usb output, with a regular usb/miniusb cable. the adapter was 500mA.( input 12V/output/5V)
it was a complete kit. you could use it for anything you want.
I only attached the TyTN to this adapter.
the adapter couldn't hold it, the amps exceeded the 500mA and stopped loading. the adapter still works on other devices.
the brodit has the same type of adapter, only with a fixed cable on it and 1000mA. this works perfect.
thats why i think that you need a 1000mA one to get it charging.
Hello,
Perhaps true perhaps not...
I used an official Qtek charger -> 1A ..it work
But not sure that due to the 1A because tried to use a self powered USB Hub and it work too ... I will check the official Qtek car charger (if nothing specific)
I use several chargers. i notice that sometimes, if a charger will only charge the device when switched off, i soft reset the device and then it will charge when on. strange problem. the problem of not charging when on, also occurs with chargers that for sure have over 1 amp.
Same problem here......tried to use the mini usb charger I got with my Leadtek BT GPS mouse......
Sometimes it will charge.....sometimes not....
Problem seems to occur when I switch the device on....ie receiving a phonecall or a textmessage....
It then stops charging only to resume after the phone goes back into stby mode....
Weird.....
Danny.
I have the same problem. I have HTC TyTN and 1A car lighter charger with normal USB cable.
Charging from normal, regular charger works. Charging from computer's USB works. Charging from car adapter works only sometimes.
I've tested about ten different car chargers, including one 2A - still nothing.
I've done factory reset of TyTN - after reset it was working for two days.
I have installed only few essential for me programs and no tweaks.
Cable is tested and working.
It makes no difference if I connect device turned on or off. It makes no difference if I reset device connected.
I have no more ideas...
I kept having the same problem but I think I've solved it.
I went into a T-Mobile shop and bought the 'official' car charger for T-Mobile SDA/MDA and I haven't had the problem since.
I've no idea what it's current rating is, because it has no relevant markings on, but it does get pretty warm in use!
help
I am really confused.
I have the sync wire that came with my device. It has stopped working as a charger from the laptop and I can;t active sync. I can however, de-activate the usb link and use the cable to activate my phone as a modem for the pc, so in theory it works at some level.
I also have another lead which is a compact one and it is giving me the same problem.
Both worked until this week so it isn't a case of them not being compatable.
Any ideas. I depserately need to sync. I can charge from the plug so thats no problem.
ahh
I have repaired actve sync and it seems to be ok now. I have no idea what happened.

USB car charger

Does anybody charge their TyTN in car via a usb car charger. I use a usb car charger for different devices: Bluetooth headset, gps reciever...
I also used it to recharge my Blue Angel.
Unfortunately I can't charge the TyTN. Has anyone had the same issue?
The charger says that it can charge 1Ampere. The original home charger is also 1 Ampere, so I don't understand why it doesn't work.
Have tried it with two different usb car chargers and both have the same problem: It charges only if TyTN is turned off. When I switch it on then the red charging light turns off.

I had similar problems except I didn't need to swithc the pda. I saw the usb charge couldn't charge completly or it was very slow to charge if I had screen with light or TomTom running.
I solved using a diferent charger, that generates 220 volts. It has 140W and costs around 40 euro.
Do you have a link, a picture or a brand name to this product?

Same problem.
I was told by the dealer that it's a matter o cable (the pins in the cable)
the one sold with the device is fine just to sync and charge from pc, but can't charge through car adapter.
I'm bought a new cable (arriving next week): it's a double cable, one side for pc, other side for charging.
if it works, I'll post..
bye
I'm afraid to tell you that your new cable will not work. You were not well informed. I am sure that it is not a cable problem, but a charger problem. According to me the power output expressed in Amps (Ampere) is not strong enough even though it says that it's 1 Ampere as the mains charger. Those cheap chinese made chargers are not strong enough for the TyTN. That's why it charges when the TyTN is switched off but as soon as you switch it on, the power output from usb car charger is not enough.

mmhhh, I'll wait the new cable, hoping it works ;.)
the fact is that with original cable the car adapter doesn't charge even if the device is off..
same thing with a 220V usb adapter.
only the original kit seems to work..
I'll tell you in a few days
btw: both adapter are chinese ;-)
Nope, Lio is right on this one. The car charger simply doesn't supply enough juice to charge the TyTN. O2 Exec users have had this problem for ages.
I use the charger bought from the Orange shop for the spv c500. Works fine, if a little slowly.
There are strange things happening!
The USB cable should not enter in to the equation as USB is USB and the pins should be wired correctly.
Here is what I have found.
If charging in the car all is ok until the power is cut, then it only charges whilst off until the TYTN is soft reset. This looks to me like there is a software / powercontroller confilct. It is a little confusing but see the scenarios below;
Soft reset TYTN, leave it off. Plug in to cigarette charger, turn TYTN on/off all is fine.
Turn off TYTN and unplug, all is fine, plug back in (TYTN off) will still charge when TYTN on.
Turn TYTN on, unplug, will not charge whilst on anymore until soft reset but will charge whilst off.
This is the same if I turn the ignition to power the lightere socket.
However, another spanner in the works, if I pull out the charger even with the device off and re-insert it it stops charging until soft reset.
What seemd to work best was to do a soft reset whilst the unit is charging and powered on. After that I was able to unplug, plug in even when the unit was on, turn ignition off/on etc... It only reverted back to not charging when I removed the charger from the socket as it was charging.
These are my findings and I presume each charger will be different.
I presume whatever electronics are in the chargers also causes problems. I have tried 2 USB and one fully wired charger and it is the same with all. I know for a fact that at least 2 of them have overcharge circuitry built in but do not think the 3rd has, I also presume the TYTN also has so perhaps there is some conflict here also.
I do know that there are car chargers specifically for the TYTN so will try one of those and see if it solves the problem. (anyone tried one?)
Anyone with more ideas please let us know.

Thank you for this tip. Now I can recharge in car thanks to u! :lol: I tried it and it works.
Great Lio,
Glad it worked. When you get a chance, could you pull out the chrger from the lighter socket as it is charging and let me know if it then stops charging again. I just want to see if the same happens to you as it did to me. It will work again once you soft reset whilst plugged in.
Thanks.

I believe this trick should go to FAQ.
A week ago I visited a lot of shops trying many mains-to-USB charges to no avail. I already had one for MP3 player that didn't work too.
After reading your post, I connected the original charger and SRed. Now that another charger works!
Can't imagine what's the reason but it really works.

Same here.
Is this a bug in the software ?
I found this : http://www.expansys.com/product.asp?code=138248
I think it should work fine, I am not sure.
"I found this : http://www.expansys.com/product.asp?code=138248"
Could you contact them and ask about its power rating and whether it is susceptible to the problem/bug?
here I am again.
finally I got the new cable and... surprise... IT WORKS
I used it without soft resetting the device and it worked
I tryed soft resetting the device and it worked
But the biggest surprise of all is that after using the new cable, also the old one started working ..
i guess there must have been a software bug that has gone (hope forever) away.
For those interested, the new cable is a double one: one side is usb, other two sides are charge connector and hotsync connector.

have you got a web link for this one you now have?
friend of mine has apparently got a tytn, I'll pick up a 1.2A USB / Car adapter this weekend and see what happens, hopefully the extra .2A should enable the tytn / exec to charge normally in a car.
Having had an exec for a while I will agree that most 12v/USB adapters struggle with the exec, but hopefully this will make the difference, if it works I will post the details of the company selling them (they are listed for the PSP)
I haven't had this trouble. Just got my new MDA Vario II and I've used it with my old MDA compact mains charger and the car USB charger and it works with no problems.
Tried it with the Vario II on and off and have a charging light on both.

charging with mains adaptor

Hi,
I'm getting some problems charging my Hero. As of last night, it's stopped taking any charge when connected to the mains (with the supplied USB cable and 3pin plug usb adaptors).... although when I connect it to my laptop, it seems to charge?!
It worked with both without issue until last night... although I do typically charge it at work via usb (except weekend, hence why I only noticed it last night).
Has anyone experienced a similar issue and know of any way to fix this?
Thanks,
Brian.
I've also tried both charging methods while the fone is switched off.... and it behaves the same way.
:-(
have you tried another charger? maybe an older style HTC MiniUSB charger (if you have one), cos it sounds like your charger's died.
Did you use the same cable for both methods (the supplied one with mains adaptor) if you did and it worked via pc/laptop then you would guess the mains adaptor has died.
I would say that your charger is dead. Power supplies on them blow sometimes, maybe from power surges, maybe they're just made poorly.
Try another charger.
Try unclipping and reclipping the pin plate. The interchangeable pins sometimes come loose.

Can't charge O2 XDA (Wallaby)

Hi! I have a prob, for me it's a major prob, since it's the first time I'm using it and don't know how to solve it. I have probs with the cradle, I can't charge it even I've plugged in the power cable (with the AC wire/adapter) to the cradle and also the USB wire connected to my desktop. I'm using Linux for my desktop. The PDA doesn't show the charging signal (amber/green light) ever, and this is a new prob, it doesn't happen yet. When I switch off the main plug, means everything that connected to, the cradle and my desktop, my PDA automatically switched on when the USB wire connected, but not switched on when it's disconnected, the power cable still remains the same, never disconnect it. Hopefully, to those who really expert about it, please help me as soon as you can.
Thanks
sounds like the battery is dead
if it works even when connected to ac but just don't charge
But before this, I still can charge it normally. How can I know whether the battery is dead or something else? Does the battery only have problem, or related to the cradle too? If I can't buy the same cradle as I've got, can I still use other cradle like for O2 XDAII, O2 XDA Atom etc?
Thanks for the replies
if it gets power so it's running when in the cradle then the cradle is fine
OK. When recently you've said that the battery is dead, how does it happen? And now, I still put my PDA on the cradle, USB and Power Supply cable still connected, but nothing happen, still not charging. So, what is the way to solve this that you might want to suggest? Rather than modify the cradle itself, because I'm not so good in electronic
batteries got a sudden time you can charge them and they die it's the same for all batteries
but if when you put your device in the cradle or connect it to the charging connector for the ac psu and nothing happens at all the device don't power on or anything then
it could be the connector in the phone which is damaged
buy a new battery they are cheap ~$8 on ebay.
i cant really understand you but I have experiance with the older HTCs horrible battery management.
plugged in+noncharging+no startup tends to imply either a bad cable or bad battery.
could be a bad phone as well, but it'd show a light of some sort i believe.
grab a new battery off ebay.

[Q] Strange charging problem

Hi everyone, hope someone can advise.
I have a UK TG01 and it works ok but overnight it wont charge from the mains charger but it charges via usb.
I have tried different chargers and an old HTC mini usb charger with a mini to micro adapter fitted but its still the same.
I have the Mugen 1300Mha battery but its the same with the standard battery on all chargers.
I have cleaned out both the charger plug and the socket on my TG01 just in case of dust but no good it only charges via usb.
I have hard reset and flashed the standard UK Orange rom but this makes no difference.
Does anyone know whats going on? it was fine, no changes or software loaded and one day its fine and the next day it wont charge??
Any advice would be gratefully received, thanks for reading.
Faulty USB sockets i think try send it back to Toshiba for warranty repair.
Not sure about that as my TG01 does charge if I plug it into my laptop, this would suggest the socket is ok?
I believe that the charger is faulty, try a new micro usb charger, or try another socket

Agreed. As the TG01 is charging via USB, then there is most unlikely to be an issue with the uUSB socket on the phone.
To tell the TG01 to go into charging mode, the uUSB connector on the charger must have the two data pins shorted out. This is the equivalent effect to connecting to a host laptop or PC when connected via a USB sync and charge cable.
If you have a non-standard charger or are using an adapter from eg. mini-USB to uUSB it is very likely that this will not be implemented.
A few questions...
- Are you trying with the supplied Toshiba charger ?
- If so did it work OK with this before but not now ? [likely duff charger]
- If a 3rd part charger, again has it ever worked ? [if not then probably missing the required pin config]
Hope that is of some help.
Hi Kevin, its a genuine Toshiba charger and I have been using it since day one.
I took my charger into work today and tried a friends Nokia micro usb charger and that worked first time so duff charger.
No, I asked him to try my Toshiba charger and that also worked
So I assume my original charger possibly may not be 'shorting' correctly or presenting exactly the right resistance to the TG01 or possibly my TG01 is getting a little fussy about how it charges.
Anyway I have ordered a genuine Nokia charger from ebay and fingers crossed all should be well and thanks for all the advice everyone.
