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.

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
radio 1.48
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,
Przemo

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.

Hi,
Wondered if anyone can help me out. I have an XDA Mini S, not been used for a while but now I've tried to use it again and I cannot get it to charge. Sometimes orange light comes on and it looks like its charging but then light starts flashing orange or goes out, device won't stay on more than a few seconds. Also sometimes get red light flashing or constant, anyone seen this??
Thanks.

battery is dead, get a new one...
It could be that the battery is too dead to get it to boot into windows. I've noticed on my G4 Qtek 9100 Wizard, that if i kill the battery all the way i cannot get it to charge what so ever.
It seems as if the charging circuit will not function unless the device is booted up. I can put the battery into a standalone charger to charge it up a bit, then put it into the Wizard and then it will charge the rest of the way after is has booted into windows.
I made a post previously about this, and got one reply which did not help, as a registry change has no function if the device cannot even turn on to begin with

Are you plugging it in with the wall charger? If so maybe the battery is dead?
Doug: The Wizard can not be charged (except by the wall charger or some other method) unless the battery still has juice. It requires extra power to jump start the battery. This is documented in the manual and in lots of places on this board...

Thanks, I did not know this was an offically known thing. It's unusual from any other standard cell phone or PDA i have owned in the past.
With them I did not need to worry about the battery running down to 0. If it did, I could just plug the phone or PDA in and they would charge, after they had charged for 10min or so there would be enough charge to turn the device on. I perfer to run my battery down to 30-25% before charging again, due to the limit on charge cycles that Lithim-Ion batteries have. Although sometimes i just forget to charge it
Those charge cycles are the reason alot of people kill the capacity of their laptop/phone battery in a few months. They constantly plug and unplug from their AC adapter. Each plugin initiates another charge, even if its just a small top off charge.
Finally got a new battery and still no joy, when i plug charger into phone i get orange light as if its charging but after about 20 seconds the orange light starts flashing (not a missed call/message as phone has been flashed and no sim card in). Do you think the charging circuit could be broken?

Interesting... hmm. Have you tried charging the battery(ies) in a different phone? (eg. a friend's, service provider's store?, etc?) Have you tried a different charger? USB-comp, wall, auto?

Tried a few different chargers, usb cable and car, none of these work, unit worked with new battery but must have been charge present when battery first delivered. Incidently all chargers used do charge my xda orbit so i know they work.

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

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

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

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

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

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 :->
Hi all, there is a way to turn off the charging function when using USB ,
1-install FdcSoft TaskMgr from here
dotfred.net/TM/FdcSoft_TaskMgrv3.3_WM6.5.cab
2-go to Devices--->$device\BAT1(BAT1 and stop this service
3-thats All
To Use charge restart this service
hey thx for the tips! but after stop the service my o2 keep saying batt low...
Is there any reason why we would want to turn off this service?

I'm not so sure about that... I've always charged both my O2 and the O1 before through usb and the battery has always been fine.
Actually, I even noticed that charging through usb takes longer but once it's charged it also lasts longer (this happened on the O1, haven't made the same comparison on the O2 yet)
Dunno if plugging / unplugging the usb cable too frequently can have some sort of ill effect on the battery life, but it's not like we're plugging it every 10 minutes is it?
Never had a battery problem with a "normal" usb usage and usb charging enabled so far...
Yes but not anymore

I heard that it keeps your battery in good shape

It's always good to drink all the juice so the battery don't develop a offline or fake "memory".
Also the multi cell assembly insde the battery praticly don't allow batery memory anymore.
Thx for the reference
Regarding battery life
Hi,
Actually, for a battery it depletes it's life every second. There is no way of preventing this But we can extend the service life. For example the most basic rules:
1-Do not charge your battery unless it is almost empty
2-Avoid deep discharging (this is not possible with a PDA coz it has an early shut down routine)
3-Do not overcharge the battery (also this not possible, coz there is a voltage limiter by hardware)
4-Do not leave your battery in a high temperature environment (for example in a car during summer, we are using chemical-reaction batteries)
the rest is do not puncture, do not short circuit boola boola boola
ok, finally while using your PDA with a USB charging interface, it should stop charging when the battery is full (Even my mother's old nokia doing this)
Plus, how much it costs for a new battery? only few bucks.. ehh.. (not for an original one ofcourse)
PDA batteries, in most cases, are 3.7volts (charging voltage is 5volts by USB) and 1200 to 1500mAh (for the ones who doesnt know what is "mAh": it is the capacity of the battery and it means if you pull for example for a 1300mAh battery, 1300 "mili ampers per hour" it will deplete. Some of my friends they are using 3.7V 2000mAh batteries while their PDAs supplied with 1230mAh batteries, thus, standby time goes up to a week. They are not using their originals ofcourse. I dont understand why manufacturers are not supplying PDAs with these kind of batteries by standart. Even a chinese made battery can be so efficient. (I am using a chinese one, my original battery is 1300mAh, i could find 1500mAh same battery)
I spoke to my friends, they are not charging their 2000mAh batteries via USB/charger while battery is in the phone. Because there is an internal electrical resistance of every battery. May be PDA's battery charging circuit get damaged! Because of this if you plan to use a high capacity battery, charge it seperately by using another charging equipment.
Finally when you want to sell out your PDA install the original battery (which you have never used before hehe ) and get a higher price
This might be some really big idiotic question, but what if the service is down and the battery drains and the phone shuts itself off, will it turn on by connecting the charger to the phone?
I ask this because with the service off even the real phone charger wont work (at least while it is on)!

Hi all, there is a way to turn off the charging function when using USB ,
1-install FdcSoft TaskMgr from here
dotfred.net/TM/FdcSoft_TaskMgrv3.3_WM6.5.cab
2-go to Devices--->$device\BAT1(BAT1 and stop this service
3-thats All
To Use charge restart this service

I just did what you said, and now the device\BAT1(BAT1 completely disappear! How am i supose to turn it on again now?
And no, i obviously didn't delect it, i just stoped the service and it vanished from the damn list!
im very interested in this but how can you restart the charging service?
