Hi,
I have a kaiser with either a mainboard/usb fault. HTC wanted £250 to fix, so a repair is out of the question.
If I charge the battery on another Kaiser and stick it in my faulty one then my faulty one works fine for a few hours (it discharges more rapidly than it should - I assume due to the fault, but works for probably 4 hours) there is no way of charging via the faulty phone mini usb connector (it lights up amber but doesn't charge, nor does the USB connection hook onto the computer).
Luckily I had hardspl on the phone from new and can easily update via the uSD card if any need.
My questions are these: How can I hard wire my kaiser to a power supply so that I can leave it on in my car at all times? (it doesn't need to be moved)
The battery is 4.2v, can I hook a 5v supply onto the 2 outer pins?
What are the other 2 pins for?
Do I need to connect the 4 copper pads in the battery compartment together?
Thanks for any help that you guys can give!

check out the service manual
Hi,
Thanks for that, I scoured through the service manual but I couldn't find anything about the voltages on the battery compartment terminals and therefore how to hotwire power straight into them, I don't know much about this and didn't want to screw it up worse than it already is by sticking 5volts onto them. Looking at the markings on the battery power to the outer 2 terminals would do it but i'm sure there's more to it than that.
Dan.
Many angles to this.
Battery is 3.7 volts. You'd want to supply that. But there is a battery charging circuit inside the phone. How that will effect things? I don't know.
There is a circuit in the battery that gives you battery % I believe. Unless you feel like reverse engineering that, you're in a tight spot.
I'd say save your cash, and buy a new phone. this probably won't end well.
on second thought. If you're already willing to hardwire contacts, why not just hardwire 5V to the USB pins?
Keep your battery in there and you'll have 5V on the usb port keeping everything happy
Hmmmn, you might be on to something with that, the problem with the phone is that it doesn't charge when hooked up. The power light glows amber but it actually makes the phone DISCHARGE faster than when not connected. Once the battery gets completely drained all I get is a RED led.
When I sent it back to HTC they said water damage right away. I know for a fact that it hadn't been wet in more than 2 months (it did get wet but only a few raindrops, just enough I guess to wet a detector strip) from when this fault occurred so perhaps it's not a mainboard fault and is in fact the USB connector failure another thread is referring to....Hmmmm.
Gonna give it a bit of thought and then either get the soldering iron out or just bang it on ebay for spares. Should think the screen assembly would be worth a fair bit!
Perhaps I misunderstood.
If you're getting the magical amber LED while the USB is plugged in, I'll say you have a good connection. I wouldn't screw with any soldering. It does sound like you have a short somewhere.
I only had my phone drain faster than it could charge when I setup a bittorrent client on my phone. Got warm!
Inspecting the board for damage might be the best choice. I've seen a motherboard on a laptop that went out with visible water damage. I scraped off an area with "ick" on it that was shorting out two contacts.
If you can't solve it that way, I'd try to disable 3G/bluetooth/wifi and see how low you can get your power consumption.

Well I'm at about 2% battery life, and it will not charge. I'm using my computer to charge it. Charging it from the wall hasnt worked for me for a while, not sure why.
Anyway I was wondering what it can be? I doubt my battery's dead or something is wrong with the phone... I'm sorry if this question's been answered, but I couldnt find an answer on google.
If USB charging works, but not charging with the AC adapter then the adapter is either bad, or plugged into a bad power outlet.
Nope it's neither of those because Ive tried two working AC ountlets and two warking cables. However, that's not my problem, my phone died and I can't charge it :-/
Ya so the phone died. It didn't look like it was going to charge on the USB, really weird. Anyone ever have there phone refusing to charge? While it was alive I tried to run activesync; that didn't work. So what should I do?
Btw, I've had the phone for a couple months now and I haven't had any big problems. I don't think it can be my phone failing, worst case just the battery. I've had something similar before but it fixed itself, doesn't look like thats happeneing now.

Maybe charging from the computer wasn't such a good idea. I recommend changing the battery and the charger and always be a nice boy and charge from the outlet ::- ).
I had the same thing happen to me - the connector at the bottom was broken. I had to do a return to factory. I looked (using a magnifying class) at the bottom of the phone and clearly see a crack in the connector.
It doesn't charge from the outlet.... I kinda just explained that lol

Hmm my connector does look a little bent. However it would of had to be like this before, and it was charging until I let my battery get to 5% :-/
I had a similar problem with my Kaiser a couple of weeks ago - it started to crawl and a soft reset took over 15 minutes to come back up to a working state, after which the battery wouldn't charge. It definitely wasn't the charger at fault as that still works on my TyTN. Phone was about 3 months old, so called Vodafone UK who seemed to think it was software related and so provided next day swap out. Old battery works in the new handset so never did get to find out if it was hardware or software that caused it to die.
Here's what probabally happened... you meant to stick you stylus in the reset hole and accidently put it in the usb hole... thus bending your charging port. I did it and when I plugged it into my car it would actually discharge the battery.. but when I plugged it into an outlet it just wouldn't charge.. if I were you I'd go see if it charges in a car
I appear to have a similar issue when charging from PC usb, and have identified that if I put pressure up or down on the charger it will charge the kaiser. But if plug in the charger without applying directional force it will not charge. Currently i have a small weight resting on the mini USB chargin input.
So obviously something up with the connector. But I haven't jammed anything up the usb port to my knowledge. Are these ports really that flimsy?
Tilt owners: If charge mechanism breaks, is ATT cool?
Oh no, now I can't charge or sync my Tilt.
My power is slowly running out.
What do I do? This is covered by manufacturers warranty in a year, is
ATT going to take my Tilt back and give me a new one?
I need my phone to be working and working well.
Thoughts?

Charging from the computer should be better than the wall, given that the USB ports on the computer have a 5.5v output, while wall chargers have 5v.
I made the mistake of forgetting to put my phone in my backpack while riding splash mountain at Disneyland. Needless to say, my phone got pretty damn wet! When I got the chance, I immediately removed the battery and let the phone dry for almost a week.
I was extremely worried when I plugged in the charger and got the red light o' death. After searching the forums I found that is was just a dead battery. So I quickly ordered a new one on ebay and I was back in business. Or at least I thought I was.
My phone seems to be fine, other than the fact that when it is plugged into a charge source, it does not charge the battery whatsoever. No matter what I use, (Car, AC , Computer) it states that is connected and charging for the status, orange light and everything, but the battery will continue to drain.
I know it is not a connection issue due to the fact that I can still synch it with my computer. For now, I have ordered 3 batteries and 2 external battery chargers for work and home. Does anyone have an idea on what part of my hardware is damaged so I can possibly get it replaced?

Ouch. If its what happened to me, its the USB port.......... part of the mainboard. Luckily mine was under warranty so I took it back to get another one. Mine didnt get wet though, but similar symptom. My usb port got blown by plugging in the wrong USB charger. I could sync, but not charge what so ever.
If its in warranty and your internal water markers arent red ( still white and dry ) Id try sending it back for a warranty exchange.
How spotless are the battery contacts - try some contact cleaner.

Have you checked that the option of not charging the battery while connected to the PC isn't ticked - if it's ticked, that'll explain why it's not charging when connected to the PC (although I don't know about the orange light). I did have a problem with my battery only charging for 1 min and then the orange light extinguished. It turned out it was due to a film of grease/dirt on either the battery contact prongs of the phone or the battery terminals themselves. If you have some contact cleaner and a cotton bud (folks in the US call them qtips), it'd be worth giving both of those a carefull clean. Note: don't be tempted to bend the prongs to touch the battery harder - they'll be fine as is as long as their surface is spotless.
Have you checked the water sensitive sticker under the battery to see if it's registered water in the phone - you may have been lucky and the water didn't get right into it. If there's no sign of that having indicated water ingress then if it still plays up after cleaning the terminals, you could try getting it repaired under warranty. The TyTN II charging system as a whole is a bit of a nightmare. As well as the problem I already mentioned, my HTC original charger only lasted 4 charges (a couple of weeks because I was mostly charging off the PC at the time) before going 'click' very loudly and going to the great charger graveyard. I bought a better repalcement for only £8.99 rather than getting another one the same under warranty which may only last another 4 charges.
The option of the battery not charging while connected to the machine isnt checked. I have a similar thing going on with the orange light. But it will happen at random times. (longer than a minute.) I will try cleaning my connectors to see if this helps. There was a little water under the battery when I removed it, and my sticker is pink.. So im thinking its showing signs of water damage. Another thing, my roomate has the same model, and when the battery is removed and a charger is plugged in, there is no light indication. But when I do the same thing I get the red light.
Sorry this was previously posted in the wrong forum, mis described as a tytn!
My son is unable to turn his tytn2 on, I think the battery has run down completely, as when I turn it on, I get the "smart mobilty" flash screen with the RGB data, then it turns off as if completely flat, when I plug the charger in, the led charging lighton the top of the phone does not light. At the moment I have tried removing the battery for a while to see of that "resets" it, I have also tried soft reseting but no joy yet.
Doing a bit of research, it looks like the fuse may have blown, I have emailed a repair company who have quoted £40+vat + £6 postage each way, which works out at £58, is the fuse the likely cause, could I get fixed anywhere else, looking on the htc manuals it would appear to definitely not be a diy fix (not for me anyway!)
Try charging from the USB cable plugged into a PC

Sounds very familiar so far... no blown fuse involved here however, it was a blown HTC supplied original mains power supply unit in my case - the light on the power supply stopped working also. Although I could have had this replaced for free under warranty, I didn't want another of the same type (which is all HTC said they'd provide), so I splashed out on an £8.99 Power Supply from a company based in Aylesbury. It has a shiny black plastic case (nicely matching the TyTN II case), works at both 110 and 230 Volts and came with 4 interchangable mains socket adapters for use with different mains sockets around the world. Before you rush out to get another PSU however, check if the light on the power supply still works. Will the phone charge if you connect it to a PC via the USB cable and does the phone light come on in this case (note that the phone doesn't need to be powered on to charge the battery this way, as long as the PC it's connected to is up and running)? If not, you may have a damaged USB port on the TyTN II and although this can be repaired, if it's out of warranty, a repair centre would need to do the work if you're not handy with that sort of thing. HTC have a repair depot in Kingston, Milton Keynes that should be able to do this sort of thing. Depending how your results go with the above tests, you could give them a call, the number is in your manual.
I have tried 2 chargers + the usb, no lights on phone, if I plug in my TP2 it charges correctly, so I think the fault is with the phone, it is now getting as far as the windows screen then dying (presumably after standing for a day or so the battery has recovered enough to go a little further) so the fault would appear to be somewhere in the charging circuit.

Which includes the USB port on the bottom of the phone. Have a careful look for any bent or broken pins there. It's also worth searching here on xda-dev for broken Kaiser USB port threads because this is a topic which has been posted about many times.
If you don't want the expense of getting the phone repaired and can make do without a working USB charging port, you can always buy a Kaiser charging cradle that comes with an additional battery bay to use as a spare charger then just use the battery bay to charge a spare battery and swap them over when reqd. You could also use bluetooth for Activesyncing (buying a bluetooth dongle for the pc to be synched with if needed).
My sons 8925 did the same thing.. and even though his USB looked to be "perfect" it was the problem... It stopped taking a charge from it.. out "work around" involved ordering one of those phone docking stands which had a seperate battery charger and an extra battery or 2.. Then he just had to swap batteries when one died and charge it in the stand.. We did a 3 battery... 1 for in the phone, one for in his wallet so he had one to swap anywhere, and 1 for in the charger.. it worked well (and he is a heavy user of the Wifi and GPS and such)..I hope this helps you out!
Hi, so this is a partial port of a thread I started over on the General forum.
I may have possibly water damaged my Captivate a few days ago. It wasn't submerged or anything, but was in my pocket when I got water on my lap, and didn't come out immediately.
I disassembled the phone and let it dry for a few days, and after putting the battery back in and starting it things seemed to be working fine. However, the battery was almost dead to begin, and when I plugged the charger into the USB port, I got an error about battery temp being too high and charging pausing as a result.
When I plug the phone in while it is off to the wall charger, I get a screen that flashes from the usual charging picture (the battery with a little bit of green in it) to a picture of a batter next to a caution sign and a high temperature thermometer.
What should I do? I see no signs of corrosion on the battery itself or the pins that connect with it. So long as the phone was not plugged in, I got no errors and it worked fine (on the 2% battery life that is now extinguished). This leads me to believe the problem is in the micro USB port on the top of the phone, but I can't be sure. I cannot see in it very well and don't want to disassemble it unless I have to.
Should I just buy a new battery? Will I never be able to charge my phone through the USB jack? Does this mean I should get an independent charger for the battery, and just juice it up that way from now on (a big hassle)? Any and all advice or experience appreciated.
Has nobody had any experience with this?
If a phone gets wet when power is applied (ie: sleep mode), usually it doesn't matter if you let it dry. The damage is already done. Moisture in the usb connector can do all kinds of weird things to a phone.
Have you tried cleaning the gold battery contacts on the phone and the battery? You can use rubbing alcohol on the phone contacts, followed by a white eraser.
I'd go ahead and buy a new battery. If it doesn't work, you'll have a spare when you buy a new phone.

I haven't tried using isopropyl yet. There doesn't seem to be any corrosion on the contacts whatsoever, so I didn't think it necessary. I'll give it a go.
It may be worth nothing that neither of the water indicators have turned color. Of course, the USB jack is a long way from where those water indicators are... It is completely plausible water got in there and never got down to the battery or contacts. Like I said, the only problems I've encountered are when the phone is plugged in to the charger...
Thanks for the advice though. I'll try it. If not, maybe its time to consider dismantling this thing and attempting a wipe down of the USB jack...
The phone got immersed in water for 1 second. Like a dunce, I didn't turn it off and it worked fine and I didn't think about it. 36 hours later, on 50% charge and not charging (after working fine all day), it isn't detecting a cell signal, it's saying 0B mobile data used for the time period instead of the gigs it was previously tracking (and had a presumably accurate number in the gigs of wifi data). All the settings looked right, so I rebooted, it booted up, and maybe 30 seconds after finishing the reboot, it instantly and completely bricked. Power button did nothing for minutes, power+down did nothing. Plugging into computer does nothing, charging didn't seem to cause any warmth although I'm not betting my life on that.
I dissected the phone and there were small amounts of corrosion on the parallel pins near the audio jack, miniscule amounts in some other places, and "significant" localized corrosion at the microusb port and where the battery connector plugs into the motherboard. If the battery connector on the mobo is bottom right, corrosion got near, but didn't get on or appear to intrude into the EMI shield to the immediate left or to the one right above that, but I can't rule that out obviously. I cleaned visible corrosion off/out, checked battery and it was 3.8V at the mobo connector piece. I detached the mobo to check the underside, miniscule amounts of corrosion, cleaned, put back together, still a brick, EXCEPT charging clearly creates warmth in the inductive charger/battery area, but power and power/down still do nothing (no corrosion anywhere near those buttons).
If anybody has any bright ideas for things to try to salvage this guy, or places to check connectivity to troubleshoot further, I'm all ears.
You could try the old fashion method of pulling out residual moisture by placing it in a sealed sandwich bag with a cup of dry rice for a couple days. Sorry this happened to you.
What about the connectors for the cable from the switch assembly? Just disassembling and reassembling has caused issues for at least a few people reported on this forum.
Also, there is a board as part of the battery assembly. Just because there is voltage from the battery, doesn't mean there is sufficient current.
On a really old battery, you can have trouble getting a basic charge (been there, done that). This problem resulted in an apparently bricked device. The solution for that problem was to use a low power charger overnight. Something like the USB port on a computer. Then unplug and replug. If the screen shows the bootloader basic charging animation (white vertical battery), the battery itself is shot. But you should be able to get it charged enough to boot using a fast charger at this point.

I only unattached that ribbon from the mobo, not at the taped-over connection, and I'm like 99% sure it's back in the mobo fine because I've reseated it a few times and it feels tight. I never touched the junction between the power button ribbon and the mobo connector ribbon so that shouldn't be it. Pressing the power button definitely feels like it's depressing what it's supposed to. But I'm not even getting to the dead battery screen so wtf knows.
The battery (would normally) have more than enough charge to boot right now. Battery life was in the hours for constant use and it's been charged enough. My battery didn't seem to match the one in the teardown. It has

written on the wrapping and it wasn't immedately obvious how to get it and the inductive charger disassembled and off the midframe (maybe it was just good adhesive since I saw nothing obvious holding it to the midframe), but I didn't see any corrosion issues externally.
