Tytn Won't Charge

I have noticed that for the last week my Tytn won't always charge itself up either when its in its cradle or is being charged via the charging lead.
I have no idea what has brought this on. The solution I am using at the moment is to soft boot, which seems to solve the problem for a while. For the techies on here I am using the standard HTC Win5 Rom, straight out the box.
Has anyone come across this problem and, if yes, knows what the solution is please? It was only because my low battery alarm kicked in the other day that I realised there was a problem.
As I use the kit for work I cannot afford to have it not charge up.
Many thanks in advance for your help.

Caveat - Yes, did search first on here and elsewhere before posting.

Could be hardware (at Device) / could be software. Without testing these things out it's impossible to say. I suppose a quick test of the physical contacts of the device would be to switch on and connect the charger and by gently moving the connection, see if the amber charging LED goes on off.
In the end I always think with this kind of problem a hard reset saves a lot of time testing this and that. If there is nothing you can pin down as an obvious change/installation you made before this started, then I'd do a hard reset.
Of course you are fully prepared for this with full backups taken at key installation stages?? - Hope so.
Mike

The only thing I've heard of is that using USB cables/cradles, car chargers and non-standard wall chargers (such as for motorola) are ok for trickle charging but if the battery goes low you need to use the original wall charger supplied with the phone.
I know this was the problem on my Wizard - wouldn't charge a low battery with a motorola charger but fine with the original.

Mike,
I think I will do a hard reset as a last, last, resort only if all other options are well and truly exhausted. I rebuilt the damned thing for the umpteenth time only 2 weeks ago and I absolutely don't want to go through that pain again.
The frustrating thing is that for the first time since I owned the Tytn (6 months) all the problems I did not know about before I bought it had finally been resolved (excepting the freezing of TomTom, which still remains outstanding).
So just when I thought I could finally start to rely on the Tytn as a fully functioning relible working tool we get this.
I owned a Sony P900 for over 3 and a half years as a business tool (grant you the PDA functionality was a tad restricted compared to the Tytn) and it never failed me once! If it wasn't for a problem with the touch screen and me thinking it was time for a change I would still be using it today.
Anyone else any other suggestions on this problem please? Wiggling the charging cable in the mini-usb port makes no difference. Only a reboot does at this time.
So damned frustrating!

hungry TyTN
Hi,
I have a similar problem. I had a go for the WM6 from LVSW (2007-05-19) and the latest Radio (1.41.00.10) and a brand new out of the box TyTN.. First thing I noticed was that the unit discharges itself very quickly. I've tried various radios without any good luck too. I think it killed my battery, at least it went so low that I could'nt recharge it normally. I had the RED LED blinking fast, constant RED and sometimes AMBER. My tip is to never let the battery fully discharge here.. I had to kickstart it with 3 AA-batteries in serial, and hooked up + and - wires to the TyTNs battery so it could have a little power, or else the TyTN would not charge it anymore. I assumed it could be my old SIM and/or the battery, so I went to th store and got a new battery as replacement for testing this. I am now able to charge, but I the power consumption is far beyond what I expect, it is like 341 ma read with ABC Power Meter....! Even with radio off, wifi off, receive incoming beams off, BT off, screen to minimum brightness, nada... I was expecting a lot less... This hungry device will not last many hours, and the battery does even produce much heat during standby operation, which is not good besides from a hand-warmer in the pocket during winter time maybe... I have also tried using Bandswitch to disable UMTS as maybe the UMTS reception here is not super good, but still working... Even talking on the phone while charging it drains the battery heavily.... to empty...
Besides from all this the WM6 from LVSW seems to be super quick and stable, maybe the very best one to pick for a HERMES.
I am desperate to find a conclusion here...
heeelp..
Update:
I happened to purchase a faulty device!!! There was indeed a HW error on my brand new device so I got it swapped with another one that works. Not all problems are SW-bugs..

Thought I would come back on this thread.
In the end I had to do a hard reset and rebuild as other problems started to manifest themselves and rebuilding became the easiest option.
Rebuilding has solved the problem; however it might interest you to note that this time I rebuilt the Tytn just like I would build a PC. The OS built itself first, with its associated apps, then I added any other additional OS tools, eg SPB Mobile Shell. I then grouped my apps into a logical order and installed them one by one.
After each install I rebooted the PPC, checked that the last app installed ran ok, then tested every other app to see if they ran as well BEFORE installing the next app. This process was a little tedious but it seems to have paid off.
I have to say though that having rebuilt this piece of kit from scratch at least 20 times in the last 6 months, I just cannot count on it as a reliable business tool in the same way as I did with my previous Symbian device. Shame given how much I spent on it.
When my next upgrade is due a Windows mobile device WON'T be on my list!
WB

Wacky - Get a full back-up tool like SPB backup and you can avoid all that pain. Hard Reset to Restoring a full backup - 10 minutes maybe. Much better than re-installing all those apps everytime you hard reset. And you can create a backup before and after each installation if you wish.
Mike

Mike,
Thanks for the tip. Must admit I had not thought of using SPB backup in the way that you suggest (can't see the wood for the trees sometimes).
Now that I think I have a stable system I will back it up using this tool and create a "line in the sand", in terms of a good system backup.
I still remain to be convinced on the stability/suitability for sustained business use though.
Appreciate your input.

Similar (Battery Meter) Problem
This week, my phone reset for some reason and came up with the screen which shows the current IPL and SPL. The phone still has all the apps and data I installed, so it was not a hard reset. This happened with a 1/2 charge on the battery.
Since that happend a full charge now shows as a 1/2 charge only on the meter and this is as high as the meter will show. The phone still lasts just as long, so there is no physical battery problem.
Anyone know how to fix this without a true hard reset.
Thanks

Mardig,
The only suggestion I have is to hard reset the unit and then rebuild it from scratch. Worked for me.
In any case it may be advisable to do this as it sounds like you have other problems.
Once rebuilt I suggest you take up Mike Channon's suggestion to get a tool and backup the device. That way if you have further problems you at least have a line in the sand to refer back to.
By the way, I am not ruling out a hardware problem in your case. However my starting point would be my suggestions above.
Good luck

Strange TyTN behavior when charging
I bought a car charger for my TyTN and used it for ~4-5 months without a problem. One day a fuse went off and after replacing it with a new one and connecting to TyTN, a TyTN stopped charging completely. I checked at home with an original wall charger - nothing. I was stupid enough to try the same car charger with my second TyTN - not surprisingly it burned the other one too :-(
I got them both fixed, a car charger replaced with a new one, so everything should have been working fine. The following happened:
1. First time a car charger is connected, it works fine and the TyTN is charging.
2. Disconnecting a charger and reconnecting it back after couple of seconds restart charging, however this stops after 1 sec and the screen shows as it is not connected.
3. Repeating step 2 does nothing - no charging starts at all.
4. Soft reset - go back to step 1.
5. When TyTN off and car charger connected - charging is working - amber light is on.
6. Wall charger (original), TyTN on or off - charging is working - amber light is on.
I did hard reset as well thinking it might be a broken driver problem, but it didn't help. Tomorrow will try to reload ROM.
Any ideas?
Help will be appreciated (before I take it back to lab and spend another $40 for repair)
Cheers

This is a known issue. It also appears you've realised the soft reset workaround:
In Car charging
(May be relevant to USB/Mains charging also)
Hermes only charges when switched off
Pulling out charger lead (or interrupting power supply) while charging in car (with device on or off ) may result in Hermes only charging while turned off
Possible Solution:
a.) Connect charger with power on
b.) Switch on Hermes
c.) Soft reset whilst connected
Hermes should now charge whilst on or off.
I charge mine in the car but I do not use a car charger but a 12 volt to 240 volt inverter - so I can plug in a mains charger. Never have problems with this and I can also use it to power my laptop.
Examples here of cheap and expensive ones - small ones and large ones:

Hi Mike.
Thanks for your prompt response.
I did read that thread, however it seems that it doesn't explain point 2 in my explanation, does it?
Update: tried the method explained, however the situation is still the same - both points 2 and 5.
Regarding the DC-AC inverter - do you use a wall charger or USB output (if there is one, I found one that has both main and USB).

Unless I misunderstand something - one of the primary causes of the problem is the disconnection whilst charging leading to a refusal to charge when re-connected. To quote my post:
"Pulling out charger lead (or interrupting power supply) while charging in car (with device on or off ) may result in Hermes only charging while turned off "
I realise of course this does not explain things and is just a statement about what happens.

THe funny thing is that the other TyTN I have doesn't suffer the same behavior and charges fine, even though I disconnected and connected many times while charging.
Yeap, it's strange, unexplainable and most of all extremely annoying.
Thansk a lot for your help.

Solved!!!
Hi.
I am happy to tell that I managed to figure out how to overcome that problem. I hope it will work for all users - I tried it with 2 different TyTNs and it was OK.
The solution is to plug/unplug the USB charger only when the device is off - not a complete shutdown by long press on Power button, but a short one.
If it's OK, when plugging the lead the power button lights up in <1 sec. If not, it takes ~5 sec to go on.
Best regards,

i discovered today....when i plugged my hermes into the car charger, that it wasnt charging.
after a soft reset it charged. an then.....no problems untill about 22:00 pm. i plugged it again and...same thing, it needed a reset to charge.
what could cause this? igo may way and bluetooth gps. coz i think this is the reason.

Please Help - Tytn won't charge!

hi every1,
i kno theres some very clever guys on this forum as many of my past problems i have been able 2 find fixes for. I hav searched the web but can't find much info on my latest problem and the info i hav found hasnt been very useful.
The problem i have is that a couple of days ago i put my tytn on charge when i returned to hopefully find it fully charged it had totally run out of battery and wouldn't turn on. with a bit of trial and error i managed 2 get it to turn on for a bit when plugged in - looked at the power meter and it said 0%. my first thought was that it must be a battery fault so i bought a new battery but i still can't charge my phone. I've tried it plugged into the mains and also through usb connection to my laptop and both have the same effect.
the problem has really puzzled me because i am able to transfer files through usb but cannot charge the phone. when i plug it in i initially get a red light but that soon turns to flashing amber lights and does not charge - i can turn it on with the new battery but it only has 50% left. i have already resorted to a hard reset and this did not fix my problem.
i would be greatful for any help or comments on my problem as i think its rather unique due to the lack of info on it.
i have an O2 XDA Trion (tytn) and it is running WM6 which i flashed myself but it is the official opperator update.
personally i feel this is a hardware issue, if anyone knows where i can get it repaired then that would be a great help too, i may try to take it back to O2 but i dont think they will be interested as i hav had it for about a year and i am now on orange but using the tytn.
cant wait 2 hear from u, thanks in advance for any help/suggestions.
Matt.

Some things to try:
http://michael-channon.spaces.live...._c=BlogPart&partqs=cat=Hermes+Charging+Issues
NB. The rocking the battery on and off the contacts mentioned in the above link, is more of a TyTn II trick but it may work with the Hermes.
Assuming one of the gold battery connector pins onthe Hermes is not disconnected then what you are trying to do with these tricks (to put it crudely) is to reset the charging circuit that seems to have a habit of getting "stuck". Incidentally this is a problem that seems to affect many phones by different manufacturers.
Mike

A perhaps first solution that has worked for me in the past. While it may seem elementary... perhaps the pins on your usb port are dirty. When I had my palm, I pretty much had to clean the bottom pins with a needle almost every time I wanted to sync, since they got a little grimey and didnt make a good connection. Try taking out the battery, and very lightly taking a needle and seeing if there is dirt or grime on the connections. Then blow on the port really hard (even better, use a can of compressed air) and see if that solves it.
Can't hurt to try
-Jotek

in reply to mike
thanks for the suggestion. hav tried these several times and had no joy, my phone does register a battery because the red light goes away when i put the battery in but there is no amber charge light just an amber light that flashes every 2-3 secs. do you kno anything else i could try or do u kno somewhere that may be able 2 fix it if its a hardware issue? thanks. matt.
in reply to jotek
i will try this as i wont do any harm but i cant see it helping much as i am able to transfer files accross usb no problem so i dont think theres any problem with the connection. thanks for the suggestion though. wish i knew more about how the phone works lol.

all ok now
just to let people know, i wasn't able to find anyway of getting it to charge again so have taken it back to O2 and was supprised to find it was still under manufacturers warranty so thay have sent it off for repair free of charge can take up to 2 weeks they said - what's the bets that its longer than that
Thanks for the previous suggestions

You mean your PC can read your phone,but your phone's battery cannot be charged somehow. Even the power is left 50 percent,you still cannot start your phone? It is strange. Have you try use the charger connect to your phone? Maybe there is something wrong whit a component about the pover switch.

HTC TYTN doesn't charge from USB and screen allignment problem

Since I bought it with the original WM5 ROM I had two most annoying problems with it (now I run WM6):
1) When I use the car charger it will only charge the first time I plug it in. If for whatever reason I unplug it and plug it again, the damn thing won't charge from the lighter charger. This is very frustrating as you can imagine since I use igo with the screen always on that drains the battery in a few hours + bluetooth consumption + the fact that phone itself rather old + the fact that igo doesn't save routes and I have to make my route all over again!
2) My screen gets missalligned extremly often! I mean like in a few tens of minutes I have to run Allign Screen again.
These are the main reasons that I stopped using it a while back, but now I need it badly for a long trip with my car. I tried to search this forum for these problems but I couldn't make head or tails of the search results. Do you know any quick fixes for these issues?
Thank you for your time.

There is a known issue where it will charge once off a lighter socket and not again unless it is switched off. A soft reset will start it charging again. (Bit of a pain).
The screen alignment issue is dealt with extensively in other threads.
Mike

So there is no workaround for the car charging issue as of yet. That is unfortunate. Thank you for your reply.

I have the same 2 problems on my TyTN (Hermes).
Right now I'm investigating the charging problem but so far without any results. As said before, a soft reset is right now the only way to get rid of it.
The screen alignment problems are most annoying since it happens a lot really. Seen solutions for that problem in other threads. Although I don't know if I really wanna risk taking the whole device apart myself...
For now I just realign when it happens (made a shortcut to access it fast).

i had a screen alignment prob but found out it was because of the firmware i had, i could not align at all was off by 5mm, what firmware did u flash it with?

HD2 won't sleep!

Hi, wonder if someone else has had this problem.
My HD 2 will only sleep when on mains power. If it on battery when I put into sleep with the on/off button it comes back on after 1.5 seconds. Same if you wait 30 secs for it to go into sleep. To fix it (temporary) I have to put it on the mains for about a minute and then it behaves itself until the battery is about 50% and then it won't sleep again. This obviously drains the battery.
I have 'hard reset' the device and it is still the same. I also updated the rom from Vodafone support site. Still can't fix it.
Can anybody out there help please, it's driving me mad!

I have this happen every so often. fixed by plugging into the usb cable (doesn'tneed to be plugged in). what I understand happens is in the usb port a connection gets wobbled and stops sleep. sometimes I have to plug it in and out a couple of times.

Thanks
Thanks, didn't try it without power. I'll just carry a mini usb connector with me! Thanks again.

that's what I've started doing.

The USB insert actually doesn't work
Hi, tried the fix suggested but it doesn't work for me. I have to have the power supply live to make a difference.
Any other ideas?

sometimes it can take a few attempts. I normally soft reset first to see if that fixed it first. other than that I don't know.
sorry!

mine's started doing this now.. yey! rinses the battery too while its stuck on.
Tried a hard reset, even a different ROM and hasn't fixed it.
I'll try a different radio next
Anyone else got any ideas? is there some software that can monitor inputs to see what it is that's waking it up?
Spike

^ different radio didn't fix

Hey.
I had this, but after a while it didn't only do it on mains.
It started to do it all the time, and as you can imagine that was killing the battery.
I tried everything! took everything back to exactly how I got it and it still did it.
so I took it in for repair, they sent it back to me and it had clearly been opened up, and the screen was brand new.
If yours is still under warenty, take it to get fixed.
I spent a little over a month looking fro a fix and nothing worked at all.

Last 3 days i also have this problem....
Anyone found what is causing it or sending it for repair is the only thing to do..

anyone please?...

Press a button .. fixed
Haha
Mine does this too all of the sudden.
There is a very, very easy fix for this...
press the right lower button (The hang-up button)
Battery life is extended from 1 day max to 2-3 days standby even!
It used to go to sleep automatically tho.
I think I probably 'tweaked' it with the tweaking tools and that's why
it does it. I'm too lazy to turn it off - and - to be honest - it's good if it's on all the time. At least my GPS won't just stop the readings I take all of the sudden.
And after I'm all done playing with Navigation, I can still press the little button.
(It really IS NOT that much of a problem to quickly press it)

You might want to install the S2U2 program, and let it manage your power settings. I've found it to be much steadier and more reliable, without those sudden wake-ups and battery draining issues.

I don't think it has anything to do with software.
It is clearly a hardware issue
I had the same problem. After inspecting the usb close, i found that there is some dirt and/or corrosion at the contacts.
I cleaned them up using some spray for electic contacts and problem has gone for almost 1 week now.
I read somewhere on XDA that an other member tryied the same thing, problem solved but came back after a while...
Anyway the fact that i cleaned the usb and the problem is gone for now shows that is clearly a problem with this part of the phone..

solved
i two have had this problem and have just found out how to sort it out. basically i tried everything new radio, rom, getting rid of CHT
and in the end all it was is the usb connection!!!!
all you have to do when unplugging your usb cable is make it come out on a angle left to right. there are obviously some very delicate contacts that get knocked out of kilter making the phone think its still on mains power when its not hence never turning off
you can confirm this error by unplugging your phone going into backlight settings and seeing if you can adjust you light setting on battery power if when you adjust your light setting nothing happens you got the same prob as me

Well, mine was fixed by a hard reset. Been testing it since, and it hasn't failed to go to sleep now.
Since there's a few different "fixes". might be a couple separate actual causes.

Started facing same problem when was on hols in +40 and quite humid atmosphere. Connecting cable helps but only if the cable is plugged in power socket or computer. And that is actually a problem as I do switch often between Android and WM and after restart HD2 doesn't go to sleep

Did this two months ago with good results ;-)

When I suffered from this problem a couple of months ago, I was flummoxed at first.
But then I decided to use a strong (20 diopter) magnifying glass to look at the ports and buttons of the phone. I could not imagine the amount of gunk I found inside the USB slot.
I cleaned with a very very small cotton swab dabbed in cleaning alcohol and wound around a pin and the problem was solved. Power consumption at rest went down from 30-40 to 4-9 mAh.
I now do this every few weeks.

I try the following, it works :

Focus charging sound notification

My Focus all of sudden started continuously playing the notification sound that is played when we connect the charger. Even after restart its still there. I took out the battery and when booted the phone started playin the charger connected notification sound.

Same Here
I have the same problem. Called Samsung and trouble shot the problem with no success. Called AT&T Warranty Support Technical Service and spent a half hour with no success. Was told by AT&T TS:
. Known MS WP7 issue
. MS is working on it
. Will be fixed in upcoming update
. Probably caused by a virus while web browsing (laughed at that one)
. They have seen many complaints about this issue
One guy on YouTube actually had his mini USB plug and connector melt. This issue also does not let your screen shut off. I found that you need to experiment with the unplug sequence when unplugging from PC and charger. Mine does it rarely anymore, if I can remember how I did this I will post.

Theres a hack in the registry that will lower the sound , Im sure you might be able to turn it off from there as well
http://forum.xda-developers.com/showthread.php?t=907971&page=36

I also have this problem. I tried replacing the battery, soft & hard resetting. nothing changed. I have tried multiple ways to disconnect and connect the phone to the charger and that doesn't do the trick also. the battery charging indication and beep are constantly playing, so the screen cannot be locked and the battery drains.
After doing a soft reset the phone doesn't stay off, it inmediately comes back on again. The same happens when I remove the batt. The only way for it to stay off is if I remove the battery and wait a while, like a minute and something. I reinsert the battery and the phone stays off.
I looked in MSFT forums and all over the internet and the amount of information is quite limited. No solution has been posted (at least none that I have found).
Also, I cannot exchange the phone 'cause I bought it unlocked over the Internet.
If anyone has any info I am sure that all the affected people will really appreciate it.

Oh. Good to know that I am not alone on this issue. I had searched the net and didnt see anyone with this issue.. I hope this gets solved in the coming update. Cause my Focus all of a sudden at anytime starts doing this. Its embarrassing when this happens in the elevator and public places and especially when you are the only one in ur friends havin a WP7 and others a Android or iPhone.
It so wierd that for any issue the TechSupport people say that 'this issue will be solved in the update'.. I hope it does!!

Hey found this forum while searching for people with this problem - so hey.
My phone (which I bought on eBay) started doing this a couple of nights ago, I eventually got to stop by doing the following (think I read this elsewhere on the net, but don't recall where):
Plug phone into charger (and charger into wall socket).
Unplug the charger from the wall socket.
Unplug the charger from the phone
Plug the charger back into the phone and out again.
Amazingly that worked for me and 3 days later I'm still ok. I've no idea if I just got lucky, or whether that sequence actually does something. Be interested to hear from others.
This thread on MS Answers is also worth a read:

Hardware issue, not software
Hi all, according to an ATT rep "this is caused by a manufacturing problem where the micro-usb power/sync connector is not always reliably soldered to the PCB". I tend to believe this because none of the software solutions seem to work (rebooting, putting it back to the previous version, etc).
Go to the ATT support forum and seach Samsung. There are a few threads about this issue. I was trying to post the links but I guess since I'm new here, they dont let me.

if it is a hardware defect (which it does seem to be) i'd contact samsung and they should have you send it in for repair/replacement regardless of if you bought it from ebay or CL or whatever, all the phones should still be under 1 year old, and as such, under warranty.

mine did the same thing i had it in my front pocket and it started to rain kinda got the top a little wet... and had the charging port open.... it started dong the charging sound after about an hour.... everthing i did didn;t work.... come to find out i had a piece of lint in the charging port and when it got wet i shorted out...... got the lint out and has been fine.... been three months now and still working great....

It definately has to do with the USB port shorting, i read somewhere that separating the flap inside the micro USB from the wall, it seems if some kind of debris inside the port can short, or also the flap seems to bend if you plug the cable the wrong way.
In mi case it seems the flap was bent, what i did was carefully separate the little flap from the wall, and it worked, the first time it did not work, but i inserted an old simcard in there and left it for a couple hours, it seems it was enough to fix this
PS. Sorry for my bad english
