Car Charing not working

[bartimeus]

I tried to charge my Tilt today using the Car Charger that I got with it from AT&T but it isn't working. I accidently jammed my stylus into the mini usb port a few weeks ago andthen but it didn't look any different and nothing seemed to break off. It will still charge with my wall charger at home and will still sync with my computer. I know that the car charger is supposed to charge my phone faster but it should still use the same connections as my regular one..right? Could it be the ROM possibly? I can't test this right now because I am at work and my phone won't sync with my work computer.

Sorry if this is in the wrong forum please move if it is.

Check the cigarette plug in your car, sometimes it can be full with dirt on the connector in the car.
I had the same problem today and cleaned it out just with a screwdriver so that its connecting now.

[bartimeus]

Well the light on the charger is lit so I assume there is power going to it and it works with my mom's razr charger. The USB port actually looks dirty but I wouldnt know how to clean it out lol

I had issues with my Tilt not charging in the car, which turned out to be a weird issue with CardExport. I had the CardExport tray icon set to autostart, and my phone would not charge in the car - only when connected to a PC. Disabling the CardExport tray icon and doing a soft reset fixed it. Now if I need to use CardExport I just start it manually.

Check your mini-usb connector on the phone, if the bit in the middle doesnt seem level it won't charge at full speed

[chaps]

bartimeus - Did you ever find a solution to this? I have been using Igo on my phone in the car heavily over the past few days for long trips. I have 3 car chargers and all wont charge the phone (resulting in no loss of satnav :-S).

Oddly, my phone shows that it is charging - sometimes only for a few minutes, sometimes continuosly - but it doesn't.

I accidentally shoved my stylus in the USB port too about 10 months ago and i wonder if this is a result of that. Odd it charges from a PC by usb and mains though - but not via a car charger.

I found that any of the Cheap ass Chargers I used won't charge it. I'm waiting for my HTC made one to arrive so I can find out if there is an issue.

I read on a thread a while back about pin 4 and pin 5 need to be soldered together for the Kaiser to want to charge.

I have this problem but have never used cardexport... any known fixes?

My car chargers are 'cheap ass' Ebay purchases. Please let me know how the HTC charger gets on.

[jackleung]

Not sure if this is the case for Tytn II, my Asus P525 need to have the middle 2 pins (D+ and D-) short in order to charge.

I vaguely remember reading that some people shorted Pins 4 and 5 and it worked.

[jackleung]

I vaguely remember reading that some people shorted Pins 4 and 5 and it worked.I don't know how you come up w/ Pin5 as USB has only 4 pins (5+, Ground, D+, D-). Read the spec here: http://en.wikipedia.org/wiki/USB

I will do the mod on one of my adapter tonight and verify it

Look for Mini-B It has Five Connections. That's what I'm referring too.

[jackleung]

Look for Mini-B It has Five Connections. That's what I'm referring too.Then it would be pin 2 and pin3 for D+ and D-.

Ok, let me share what I found so far and the result turns out to be very surprising. I have 3 different cigarette to usb adapter (yes, I got lot of gadgets to feed in my car. ;)). And the test are done w/ maximum backlight and A2DP music to my JVC BT-1.

1. Cheapo w/o current rating label, (I guess it's about ~500ma). D+ and D- shorted
2. Another cheapo rated w/ 650ma. D+ and D- NOT shorted
3. An expensive one w/ rated at 2A (yes, this is the only one w/ enough juice for my power hungry Dell Axim x51v). D+ and D- NOT shorted.

result: 1 = work, 2 = not work, 3 = not work.

Then I shorted both 2 and 3

result: 1 = work, 2 = not work, 3 = not work.

It seem shorten D+ and D- does not change the result. Just about to conclude I didn't prove anything and about to give up, and I try a different USB to mini-USB cable. It surprise me all of them are working!!!

From the pic below, the charging icon of battery status mean the cable is connected. Current w/ a plus sign mean the Tilt is being charge

Cable 1:

Cable2:
http://img524.imageshack.us/img524/2099/cable2mp8.jpg

Therefore, I conclude:
1. it turns out my AT&T Tilt are very picky about the USB cable quality.
2. For cigar to USB adapter, maximum support current and the quality may not very important.
3. We may or we may not need to shorten D+ and D- since I don't want to spend time to unshort them.

p.s. I still don't understand why cable 1 gives bigger charge on adapter 1 but refuse to charge on the rest, while cable 2 give consistent charge on all adapter. I re-test several times but gives the same result.

[JimmyMcGee]

Short Pin 5 (+5V) and Pin 4 (unused). And tell me what happens.

[jackleung]

Short Pin 5 (+5V) and Pin 4 (unused). And tell me what happens.The mini-usb plug is too tiny for me to work on it. I will pass it to whoever has the tool to test it.

[chaps]

Right, as I posted earlier, I have 3 cheap car chargers - 1 with integral cable and 2 that are just the adapter and require a separate cable. None charge my phone. A usb cable that works from my pc fails to charge in the car.

So, I bought a genuine HTC car charger. I fully expected this to work fine, but it doesn't. It does exactly the same as the cheapo chargers - My phone shows the amber charging light for a minute or two, then it goes out. No charging takes place at all. The battery icon shows charging all the time the cable is plugged in though.

My ciggarette socket is fine and supplies enough current to make the ciggarette lighter thingy glow hot.

/baffled.

[bartimeus]

Hey all, No i have not yet found a solution for this problem. I believe I have a genuine HTC charger or at least an AT&T one because i got it witha bundle with my phone from AT&T. I am looking at the USB plug and it seems to be bent down a bit on the right side as you are looking at it.

I think i might talk to my girlfriends cousin who works for AT&T and see if he can be awesome and replace it for me without me having to put the AT&T crap back on there for an actual warranty return.

still charges at home wall plug in and syncs with my computer just fine

[houie67]

This is how i get around this happens, though it sucks if you're using it as a navigation device. When it stops chagrining through the car adapter, I leave the cable plugged into teh phone and the cigarette/power adapter and do a soft reset. This seems to clear it up somehow and it starts charging.

[bartimeus]

Mine never even begins to charge though.

[chaps]

Do you have other USB cable to try?

Yep, and that don't work either. For me at least, I think there is an issue with my phones mini usb.

[Lauicek]

1) My cheap car chargers charge great :)
2) My genuine HTC charger don't charge after 1-2 min. :confused:

have 2 other chargers who dont work..

[o2xdaexec]

easy way is to hunt down a car lighter with the usb on it the plug in your usb lead works for me as i have a 3-1 adaptor so i can use the music in the car with the head unit.

have 2 other chargers who dont work..No, the 1-2 mins light on doesn't mean it is charging. That's probably the time it try to verify the connection. If you have battery status installed and watch that closely, you will find that 1-2 mins does give you any charge at all

ok so i got a usb car charger and connect a usb cable to it but it doesnt really charge

like noted above it turns the light on as if it was charging for about 1-2 minutes and then it goes off

The usb cable does work when i hook it up with my computer though and it gives it a full charge so i assumed it is not the cable, but i might be wrong.

does it need a specific usb car charger?

[Fulcrum1]

Same problem here:

5 Usb cables + 1 Ac->Usb adapter + Original HTC car adapter
- None of the cables charges trough the Ac adapter
- 4 of them charge trough pc's usb
- The car adapter doesn't work

A little off topic but what plugin are you using Jackleung that gives you the battery current on the today screen in the screenshots above?

[Fulcrum1]

It's HomeScreen PlusPlus, formerly konwn as Batterystatus.
That's the developer's site (http://www.chi-tai.info/cs_batterystatus_xda_neo_wm5_im_cs.htm#Download)
You can download the basic version...it'll show up the infos you need.

Fulcrum

[Fulcrum1]

I suppose this procedure has been described many times...repetita juvant.
You can try this on a spare cable, just to see if the charging problem can be solved with a little diy.

Shorten Pin 4 & 5 on the cable and everything will work fine:

http://upload.wikimedia.org/wikipedia/commons/thumb/5/56/USB_AB_mini.svg/250px-USB_AB_mini.svg.png
(yours is Mini-B)

1) With a needle lift Pin 4
2) With a screwdriver bend it over pin 5 and press it until it stucks and you can easily insert the connector it into Kaiser's miniusb.
3) Job done

You should solder 4&5 to finish up the job, 'cause the shortened pins can break during everyday use.

My charger doesn't work properly either - it slows the discharge on GPS but it still keeps going down.

I haven't tried playing with the pins given the mixed reports on here. Would be interested to hear more reports whether it works.

BTY I have a cheap car charger from Amazon - it is an Elite charger from Elite. Also bought the Herbert Richter cradle and that works fantastically - just wish I didn't have to worry about the battery on long journeys.

Again normal charger, usb charger, blackberry usb charger all work fine.

[tryps]

First, I'd like to thank Fulcrum 1 for that diagram and directions.
My tilt charged fine with the car charger worked for well over a month (cheap charger from the store I bought my Tilt). Last week it just stopped working. Blindly following suggestions here, I shorted out pins 4 and 5 in my charger and all is well again in my car charging world.

I am curious as to why this worked. Can anyone explain this?

I don't recall exactly But If 4 and 5 or shorted out The Kaiser knows that it won't be receiving anything on the "data" connections.

[tryps]

hmm, I just noticed that my phone doesn't charge on my wife's USB AC charger (was sitting right next to mine and I grabbed the wrong one). I do not know, but suspect that my AC adapter has 4 and 5 shorted out but her's doesn't.
If there is not data connection with 4 and 5 hooked up then why does my phone charge on the PC?
I suppose it can all remain a mystery until one of them fails.

[MortalX]

My charger works fine for 3 months and now after 10min in igo 2006 it won't charge untill i restart the device.

[d200]

I found myself with the same problem of not being able to charge via usb or car charger. 5 minutes of moving pin 4 to short with pin 5 and problem solved.
many many thank for the information this forum really is a credit to all you knowledgable guys. certainly keeps me interested in HTC devices. thanks again.

[cabana chives]

I'm fairly new to all this but having the same problem...

Anyone come up with a solution? I've tried MULTIPLE car chargers and wasted money and none of them charge my Tilt! Can someone explain, in detail for me, the dummy, the whole 4/5 pin thing...I don't understand but I'm willing to try! Thanks!

[jaydiamonds]

I had the same problem like 3 days ago. Bought mine from an At&T authorized dealer, it would only charge at a certain angle. Went to a store an exchanged for a new one and it works with no problem. Looks like At&T might be selling some defected chargers here.

stupid question but: have you ever tried to buy the official HTC one (http://i.expansys.com/i/b/b147571.jpg)? For me that's only one working (i.e. charging). Thus with Tomtom 6/7 runing, it also reload the battery, not only keep it alive while discharging.

NO "stupid question" but you give stupid answer.
If you read the topic, you'll find people who have problem with official HTC one so do I.

I may give "stupid answers" but you post empty comments, what's better? I am giving my feedback, not the absolute Truth. You can save such comments imho. I see you had problems w/ the officail one, great, I had problem w/ 2 euros one...

[Skirr]

Sorry to bring this one up, but I have the same problem.

I bought my car charger to use GPS in car, because using TomTom leaves me with a drain from 260 to 320mA.

But when I use this thing, the Kaiser recoginzes its existence but then wont recieve any voltage input. Instead, after a few minutes, Battery Status just shows the normal drain again.

Is the pin shortening the only and actually working solution here?

[cBorisa]

I faced the problem with car charger from Interstep.

Symptom: the device orange LED is on for 3 min and indicator shows charging of the device, but no actual charging is there.

Description: after reading several descriptions about Mini-USB pins, I figured out that HTC Kaiser gets power on PIN 1 and ground and some indicator signal on PIN 4 and 5. Pin 2 and 3 are for data.
My charger has PIN 4 and 5 are short-circuit.

Solution: when I opened the charger's connector, I've noticed PINs 2 and 3 sometimes can contact the wires from PIN 1 and PINs 4&5. I have removed PINs 2 and 3 completely from charger's connector and now device charges without any problem.
