need expetise and advise
my ATOM cannot charge and cannot connect via activesync
battery and usd cable and power charger are proven OK, tested with other Atom , it works
now suspect mini usb port problem or software or other hardware problem
when i hook up charger or usb cable , the red light on for a while and off
i can see the charging logo on for a while, i go to POWER screen, can see charging but just a while only
tell me all possbile solution
million thanks
This could be hardware error...the usb port...
But...try it with carefully plug the usb cable, slowly...don't pull it to end of device slot...
Just untill the red light of battery charging turned on...then leave it...
hope this help...
cmiiw
same problem..
i had this problem recently as well, mine turned out the usb sockets on one of my notebooks couldn't cope with the current being pulled to charge and so shut themselves down stopping the charging after a few seconds. i found a mains to usb charger plugged it in and left it for an hour and all was ok again. if you don't have a mains charger try one of the dual usb to mini leads you get with some external drives, the one i tried seems to spread the load enough to charge the device
hope its something as simple as this for you as well
the atom series from quanta have a lousy usb port and ear piece component used
both of these component need to be hot air-ed out of the board in order to do replacement.
the usb port will be easily fallen off from the board due to poor soldering or mis-used by user.
the ear piece 2.5mm jack will be spoilt when frequently used and headset unplugging from device. when faulty, the device will think that the headset is still inserted & do not project the sound out during a call from normal hearing speaker (user can only use bluetooth headset to do calls) the mic will not work too if loudspeaker mode is on.
my 2cents, find someone skilled to replace them if they still can find the component in market & u think its worth servicing or buy another model.

Hello,
I work in IT, and have been given two of these phones that both have their own problems. I finally found a disassembly guide at http://www.pdacenter.ru/razborka/razbor_htc_star_trek/
The one phone has no charging port at all. The other phone has a broken external LCD screen. So I want to move the working external LCD from the phone with the broken proprietary usb port to the phone with the broken screen. In theory I should have a working phone.
Now I don't have any wall charger for this phone (blasted proprietary port!) But I have the usb sync cable that fits the phone. I tried plugging this into 4 different USB ports and none of them will charge the dang thing. I guess my question is, does the USB sync cable charge the STAR100? I have two batteries here that are dead (they sat around for months). I know my Cingular 8525 Hermes charges via the USB port (although that port is very flaky, I use a desktop charger).
So am I out of luck, or do I need to get a wall charger? I could find one at work to test tomorrow, but I would of liked to test it now.
move
instead of doing that, move the working control board from the one with the good charging port to the other one, it will be much easier and yes you can use the usb to charge.
Thanks I got it to work.
Today at work I sourced a wall charger. That made the LED light red on the phone, after awhile it turned orange, then green (after about 4+ hours). Now it appears to charge off the USB cable at home.
Now if I can only figure out how to get a T-Mobile sim to work in it, without paying an unlocking service (I have enough bills to pay with a wedding coming up this October).
Does someone know if the HTC shift can be charged via the USB port?
This might allow: 1) use of an external power supply via USB; b) hot swap of standard Shift battery 3) Emergency power in a pinch...
Should it be possible?

No
The shift needs alot more powere than what a usb port can provide, so it's newer going to happen
Yup = the charger outputs 12 v and USB is of course 5 v - Too bad WOuld have been cool to hot swap the battery though...
another charging-related question
My SHIFT has stopped recognizing when the external power supply is plugged in: no orange LED, no icon toggle, no switch to the plugged-in power management profile. The battery charges okay, so I can live with it, but it is annoying. I suspect a component in the charging electronics has failed, but am curious about alternative theories, and if anyone else has this problem.

HTC Red light of Death
Guys,
I am a service tech for HTC. I would like to tell you couple of things.
When there is red right, Battery will not charge with the chargers (Electrical or USB). It will flash with Car Charger as the charge is high in Car charger.
If you see Red light..your Battery is fine. there is no point of changing the battery.
There are two IC in the motherboard of HTC. One is the Charging IC & the other one is Power Consumption IC. You need to Change the Power Consumption IC, which will cost around 10-20$.
Dont follow unnessary steps as it will affect your PDA ROM sometimes.
YOur HTC will work fine for ever.
thank you for your answer

Thumbs up HTC Red light of Death
Guys,
I am a service tech for HTC. I would like to tell you couple of things.""
so you said you are working for htc ? if so i suppose you re not allowed to give us some clues about the very specific clio hardware, like the sd card link with the snap vue side..
anyway i think you are very welcome here!
woooooooow ur welcome here defenatly, at least we can pick ur brains with few things, plz plz plz make our shift upto expectations by giving us clues not solution but pointers for making BT and SD work
looking at his lack of spelling and grammer i think he might be a joker especially his last part " YOur HTC will work fine for ever. " erm he would no thats not true if he really worked for them.
tho i hope im wrong and they can get us a shift that works with the odd lil leak of info.

Hello friend,
I am unfortunate I damaged my Shift when power accidentally went in through the USB port thus damaging the power consumption IC in the motherboard. Unfortunately I dont seem to get the replacement part anywhere. You had mentioned that specific part in the post mentioned and I was hoping that you might be able to assist me.
Here is the thread about my unfortunate Shift..... http://forum.xda-developers.com/showthread.php?t=701950
Car power adapter 15-25 for my htc shift is it possible?
Hi to all.
Yesterday I bought via internet a car power adapter like this:
http://cgi.ebay.com/15-24V-80W-Car-DC-Power-Adapter-Auto-Charger-Laptop-/180476771054
But my HTC SHIFT can be recharged with 12volts typical so question is:
CAN I USE 15Volts (minimum output from my new car adapter) to power my HTC SHIFT or is just a little bit more. I suppose max 20% more is just good but not more than this.
I must put a zener diode ... to reduce a little bit or as in your opinion I CAN USE IT WITHOUT PROBLEMS.
Thanks
sullivan2002
Thanks for the idea! I would defenitly put a zener between there just in case. Do make sure you use a high amp zener. I could build a boost converter to get from 5 to 12V but that would cut the amps in more than halve but it could be nice to use an external USB battery to swap my shifts battery. I have 3 battery's so that would be nice. Any idea how much a sleeping shift uses? The converter won't be able to put out more than 200mA becouse of the USB restrictions. Is it possible to keep it from charging when swapping battery? Becose i think that charging uses a lot but a sleeping shift almost nothing(not hibernate).
Guys be very careful when using chargers that are above the Shift's specific power rating. My experience with the Shift confirms that HTC did not think about safety measures when putting the Shift together. I had a small freak accident with the Shift when power entered through the USB port and instead of just blowing a fuse the entire motherboard got fried! You dont want to fry the motherboard coz getting a replacement motherboard is as difficult as swimming across the Atlantic. Ask me how I managed to swim across I will tell you.
So I would advise you to tread very carefully. For me what I did is that I had a 12V, 2A car charger for a different device lying around. I simply cut off the power jack on that car charge and replaced with one similar to the Shift wall charger jack and all is good. Of course you also have to be precise about the polarity. The Shift has several week points that you dont want to mess with
They say that the charger of an EEE PC 901 an the Asus R2H have the same charger as the shift. That is only partially true. The specs on the charger is the same but the shift uses a slightly smaller jack. The eee and the R2H are interchangeble. I have a friend with a 901 and it charges my R2H just fine. Shame becose I have 2 chargers for the R2H and only one wonky one for shiffy.

True it has been confirmed that Shift Charger and eee Pc is one and the same. Only difference is the jack.
http://forum.xda-developers.com/showthread.php?t=502548
So if you have a eee pc or similarly rated charger lying around you can replace the jack and you will be good to go. You can pick the Shift size jack from any elctronics shop. Thats how I managed to rig myself a Shift car charger
Hi new member and new owner of a 4G shift
to answer the OP 's original question of "can you charge off the USB"
it depends on your motherboard, I have a Gigabyte X58-UD4P and with the USB power switches enabled my phone will charge while connected to the USB port
I have 4 PCs set up and my personal rig is the only one that will do this
Now a Lap top is a different story, I would suggest checking with the manufacture
of the Lap top to see if the USB can be used for this function
usb
i charge mine vis pc usb sometimes.
works but a lot slower than the stock charger.
Could you explain if it's necesarry a especial cable or how do you conect the Shift's USB port to a energy usb porwer source?
If you are traveling and need to use GPS, but maps are loaded on a external card and you have your viewpad charging on lighter outlet.
or (my case) you have some serious amount of text to write and you need the keyboard connected as well as your wall mount charger....
Is there any known way to connect the battery charger and a peripheral as keyboard or usb mass storage device at the same time?
I'm thinking about some surgery to the usb-to-miniusb converter that I use to connect my desktop type keyboard to the viewpad, but don't know what could happen to the usb device or the keyboard. Neither know which of the 5 pins (contacts) of the charger is the active one...
Any suggestions?
Tnx in advance.
anothe question....
Ok... since there is no answer over 24hrs, I'll make another question to make this a little more interesting for you people could help me...
Is there any chance to connect a keyboard (already working) plus a SD card at the same time??
I'm making some fun stuff with a keyboard and making some surgery I could install some kind of "external USB Port" on the keyboard.... but, should it work?? I mean, keyboard and flash memory together, connected to one-single miniUSB port....
Developers.... any suggestion??
Thnx again...
Forgett to say.... on Viewpad7 with FROYO 2.2.1
Another idea
Ok, easy people... That bunch of comments about my topic make s me feel kind dizzy...
Just kidding....
Making some research (on goggle, haha!!), I've found that USB port on a pc have a 5volt-500mA output... So, if that's nominal out and that power could charge the viewpad AND don't turn on smoke any peripheral, Then I just have to connect power out on a wall-mount charger to the 1st pin (wire) of a 5 contact miniUSB, regarding on the power out put on 500mA.
(thanks isIran for your assistance )
now... PLEASE SOMEONE STOP ME IF I'M HAVING SOME IDIOTIC, TABLET BRICKING, IDEA!!!!
Thnx again
Hi,
The Viewpad wall charger have a non standard conector, if you look in the contact part you will see double connection.
In the main charger body you will find the pinout:
Pin 1 & 6 +, pin 5 & 10 -
These pins (6&10) are longer than the data pins to ensure that the power connections mate first and un-mate last.
The wall charger is 2 A and the USB PC port only 0.5A (0.9A for USB3)
For this reason a wall charger change in 2 hours and a PC USB in 15 hours.
A dedicated USB charger should short the 2 data lines together. The device will then not attempt to transmit or receive data, but can draw up to 1.8A
for this reason the device know when it's connected to a computer or to a dedicated charger (like a Garmin GPS)
Probably modifiying a connector (or keyboard) to provide energy and data will work.
Did you try a USB hub?
Less us know the result of your experience.
cheers
You could solve the keyboard problem by using a bluetooth keyboard and you can charge the tab on the USB port at the same time.

Right, this solve one problem, but is much expensive and less fun... Besides, didn't solve the flash drive plus charger issue...
About pins 6 &10... Just noticed that (in over a year never look that closer the charger pin).
I'll try usb hub, but I'm afraid to burn some flash drive or worst...
Thanx for your interest and helpful advice...
I have a Samsung Galaxy S Wifi 5.0, and lately it won't charge naturally (it doesn't charge when you just plug the USB cable to the port and to the wall), but you need to charge it a certain angle (eg move it until you hear the charging sound but afterwards it won't charge when you remove it!)
I have the original Samsung adapter that came with the SGP Box, but I replaced the original USB cable with another one because of the charge-at-a-certain-angle problem. I changed my USB cable thrice now, but the problem persists.
The weird thing is, it charges perfectly on a BLACKBERRY CHARGER. Although the problem is still there when I charge it with the BB charger, it never got to the point where I had to apply so much pressure on my tablet.
I just want to know what is causing this problem and a solution. I can't always use the BB charger since my sister brings it with her to school everyday. -_-
I had the same problem with my Galaxy SI. I was forced to place a book directly under the usb cable so that the phone sloped downwards. I had different luck with different usp cables. My girlfriends usb cable -that was relatively new worked fine as it sat quite snuggly/tight. Others, new or old, that did not sit as tight did not work.
Take you phone to a PC hardware store and test a few.
Hopefully you will find that it is the usb cable that is worn and not the inside of the phone.
Thanks, I'll try that out!
Hi all, my lumia 920, does not recharge any more when plugged in USB cable.
It isn’t even recognized by my PC. It seems the USB plug is dead, regardless wich cable I use.
Is there any possibility to get it working??
The problem is that I live in spain now, and bought the lumia in germany, so there’s no way to bring it to customer service. Anyways I don’t even like customer service, because they give you the phone back in bad conditions, with scratches and even bad mounted parts, like display etc..
Thanks everyone for the support!

Sounds like the USB port is damaged, why are you even using the USB when this phone has wireless charging? Just get a wireless charger and don't worry about it. You can share stuff between it and your PC by using the cloud.

The microusb port on this phone is soldered in a weird way from others. All it takes is a pull from the side on the cord while it is plugged in and the connections on the PCB can be broken. This phone is not Android and therefore the charging is not software controlled. it can be totally dead and will still charge through USB and wireless as the wireless base will supply power as it charges.
No this sounds like a hardware issue so you should try to get a warranty claim on it and hope you have the extended warranty as damage caused by use or handling is not covered by Nokia's warranty.
i have a semilar problem.
After a total discharge of my battery (I used it as navigation in the car but forgot to plug the power) my Lumia 920 wouldn't reboot (it gives a red battery). Nothing worked to bring i back alive (i did a soft reset and even hard reset!) but when i got home the wireless charger worked. (
But still nothing on the USB plug. My first conclusion: USB port dead. But when i plug in my powercable the Phone gets warm as it is charging. One more test i did is. When i place i on the wireless charger (charging starts) and then connect the USB to (for example my Laptop) charging stops. Next simple conclusion "USB port is okay", but maybe it's because of som battery security feature (bug)?
Anyone??
