Hi,
My Xperia Tablet Z stopped working. I suspect the micro-usb connector failed. I want to try charging it using the two copper docking contacts. I'm thinking 5V will do, but I have no idea about wich connector is + or -
Any help is very welcome.
Ragards,

Hello!
Upper one is + (plus), down is - (minus).
Thanks. Fixed it by replacing the connector and disconnecting and reconnecting battery.

Anyone know about a splitter that will take the 30-pin input and let you use one side for the 30-pin power adapter and the other side for 30-pin accessory like USB OTG pigtail?
I'm in the same boat,
Search and search but nothing,
You get USB to 2 30-pin but nothing for 30-pin to 2 30-pin adapters
The only option you have is to buy a Galaxy Tab break out board from Kinetica and solder your own cables to it..
What do you want to use at same time?
It would be nice to run external power while having an accessory plugged in such as the SD or USB drive or keyboard. I have 2 USB keyboards that have the pointing device built into it.
look in m y post in the make your own cables thread.
i added power to the odks circuit board and can watch movies via hdd at same time as charging.
easier way would be use the breaK out board though..
I have the connector parts, just I have to know the pin assignments...

Look at this thread..
Try my post first one before this page..
It explains it..
pin 7 is the posative 5v @2amps...
pin 30 is the earth..
(this is how i run it in car connected to 2 amps 5v source)
works well and if start close to 100 percent battery power leave it plugged in it doesnt drop anything even after watching 4 movies in a row still is 100 percent.
eventually i disconnected it to let the battery drop down alittle as not sure if good to keep it at full charge?
Maybe the best way would be try to follow my dock mod?
that way you can just use the 30 pin usb adapter and add a powered hub.
havent given an update on "line out" output as my usb adapter is covering it up
the outlet socket.might consider opening it up again and finding out if works then relocate the 3.5 stereo socket outlet.maybe could just solder some wires to it inside and add a new output some where else more accessable..
This is a bit of an old thread, but thought people might like to know that I have found a solution! DealExtreme has a splitter that has 2 OTG connectors and a charging connector....

Havent seen that cable before...anybody tried it?
Just curious IF and HOW it works...
I modded my dock to accept charge and host at same time but only triggers charge when hdd is connected whilst power applied.
I've got one from ebay. But its very poor quality. Its functionality is OK, but you cannot charge the Tab. External power is used to power the USB devices. It switches between internal Tab 5V and external 5V when applied. It ok with USB hdd that needs power.
o.k. thanks..
Cant help but wonder about the possibility of using it as charging and host at same time by using different resistor than 20k.not sure if you guys seen the thread about host and charging on galaxy s3 (hw mod) but they discovered a different resistance value 40.2k that could make the power part of the usb travel in both directions at the same time allowing this to happen...
im thinking the same could maybe happen for our 7.7 tab.

Ordered this one few days ago but unfortunately it's not in stock and they don't know when they will have it back in stock so, are there some other options?

Hey, did you get it? How is it?
Hi,
my screen of the archos g9 (1ghz, 8gb) is broken.
now i want to use the logic board like a raspberry pi.
i have bought a mini hdmi to hdmi cable.
i removed the battery, so do anyone know if it will work without the battery (by just plugging in the usb cable?)
which pins should i connect to let it boot?
Hopefully someone like scholbert can help me with this problem,
Nick

i have the same tablet as you and my battery still slowly discharges while plugged in if im actually using it. just a thought but maybe youll have to put the batteries back into the tablet
although thinking about it since your not using the screen at all it wont be drawing any power and from what little i know im pretty sure thats the most power hungry part of the machine.
Yeah, but I tried to boot without battery with no success
On some things you need to connect 2 pins to get it working

You can try... but i guess you'll need to tweak your Android system a little bit to make it work.
For example, i found out that Android refused to start up completely without the touchcontroller connected to the internal I2C bus.
Another thing might be the avtivation of HDMI.
Never tried it though.

No, plugging the USB cable is not enough. But you can power it up without batteries. There's no need to connect some pins directly, though it might be useful to similate the NTC. Read on to get it work.
As you know i use my A80S mainboard for experiments and i use a LDO to power the board instead of batteries. You'll need some soldering skills though!

As stated above this won't work.
Please see the attached pic.
I use a simple wiring with an LDO adjusted to 3.8..4.2V and connected this cicuit to the battery solder pads on the mainboard. Completely unsolder the battery wires first.
To avoid temperature warnings i soldered an additional 4K7 resistor at the NTC solder pads.
You may use any adjustable LDO which is capable to deliver at least about 1.5A max. current.
The example in the pic uses the LDO from Pandaboard.
It is adjusted at 4.2V, which is the approximate maximum value of a fully charged LiPo cell.
The datasheet could be found very easily in the web, to get further information.
Happy hacking!

thanks for your post, i was on holiday so i couldn't replay earlier.
seems like i am just going to connect an battery then
If i get some money i will try the way without the battery
i can't use the board for something else so this is a nice "hack" project for later
Big thanks
Hello
I have a big problem with my Razr, my usb connector of my razr is broken.
I can not charge it anymore, it is not caused by usb cable because I tried with differents.
Someone know if we can buy new usb connector and replace it ?
Thanks you.

Is the connector on the phone "physically" broken, or does it just not charge?
It just doesn't charge.
But the connector is damaged for sure.
Just as a temp solution you Cern use battery charges (connecting their probes directly to the bat. + -)

I tried to do that yesterday but it didnt work.
I cut an usb cable and I put the red and black wires only on screw (
I did not have a screwdriver )

Hello,
I have problem with power connector on the tablet. When charger is plugged in it moves left and right slightly, making rec power light disappear, screen flickering and even continuous tablet restarts.
There are two possibilities:
1. Charger cable is problematic
2. Charging port is problematic (it has 0.8 Nokia like round charger plug).
I do not have spare charger to test, but from what I see, more probable is that charging port is problematic.
So here are questions:
a) Where can i buy such port on e-bay to solder it in place of old one (someone who knows please answer me)
b) Since battery i very weak, can it be ordered somewhere on e-bay or similar site?
c) Is there a way to make tablet work directly plugged in (charger directly connected to mainboard)
d) Your suggestion (other than throwing tablet away, because I know that one on my own)
Thank you in advance.
Hi guys, looking for some help here. My goal is to use a tablet with a seek thermal USB camera plugged into the charging port. It's going to be mounted in a semi-permanent location and running non stop, so I'll need to keep power to the tablet at all times. Is there a solution for this? Is there a way to plug power into the charging port while also allowing the OTG item (Seek Thermal) to work simultaneously? I've looked at some connectors on Amazon but it's very unclear if they will only Power the OTG item but not charged the tablet or both. I thought about using inductive charging for the tablet, but I'm failing to find any tablet that has an inductive coil built-in.
I'm going to purchase a new tablet for this so I'm open to whatever model works. Right now the Seek Thermal is a micro USB connection but I have a micro USB to USB-C connector just in case the new tablet uses a USB-C connection.
Thanks so much in advance!
