In an attempt to add induction charging to my Nook Color, I mangled the connector that attaches the battery to the login board (battery side). What is this type of connector called? and where would I buy one?
Thanks.

ok, the connector is broken.
I disassembled cover parts,
fixed connector,
I'm sure there is 5V inside (the connector inside I measure by voltagemeter) when I plug-in the external charger. The connector has 3 pins for GND and 3 pins for 5V and I'm sure there is volatage inside.
But the battery is not charging. O/S say the battery status as remained, but do to charge.
how to fix? what next to check?
crying:
You could check to see if the protection fuse has blown, if so you can bridge the circuit, if you search for charging or charge on the forum you will find pictures and methods.
the protection fuse just beside the battery? under small piece of white scotch tape?
fixed
thanks for suggestion.
yes, it was broken micro fuse, the one right beside the connector pins on motherboard.
Glad to be of assistance, hope its all ok now. 8)

Hi Jgui, could you tell me how you managed to repair borken connector at th bottom??
I search for a repair shop for my MDAII or th way to do it myself...
thanks a lot for your answer
My microUSB adapter coupled with the USB light is too heavy. I have to hold the nook upside down so that gravity will push down on the microUSB port. Furthermore, as mentioned in other threads, Android 2.1 doesn't allow the screen to rotate 180 degrees.
Do microUSB ports have a lock like Apple's dock connector? People have attached wriststraps to the iPhone's dock connector.
Is there another type of microUSB adapter I can get?
Oh, supporting your light off the connector is not a good idea.
Somebody should do a teardown on the glowworm to see if the LED is fed off a spare regulator in the TPS65921B (TWL4030).
Then you could use the stock glowworm software to control your light.
You wouldn't be using the USB connector.
You could either hardwire it or put a jack at the top.
I should check out making all 4 orientations work.
Sorry I'm not familiar with electronics terms.
I used the microUSB port after seeing this guy's photo.

Does hardwire mean solder the light like

And putting a jack at the top means creating a USB port by attaching one to the regulator?
All these require drilling the holes in the case...
I don't like putting stress on the poor little micro USB connector.
I wouldn't ever use one of those block adapters that you use.
See the adapter in the attachment photo here: http://forum.xda-developers.com/showthread.php?p=26286972#post26286972
How about clamping the light on the top edge of the Nook and running the cord in the back?
It looks like the Nook Glow uses additional hardware for the power supply of the glow.
Yep I've seen those adapters before for attaching peripherals to phones and tablets. Before this I didn't know OTG was a common type of microUSB to USB adapter.
I bought the block adapter without thinking of the weight factor because it fit. And that cost more than the OTG cables!
Don't do it!
Listen to Renate. Unlike "normal" USB (-A, -B, mini-) connectors, those micro-USB connectors are usually just soldered to the top of the circuit board, instead of with a hole-through. Thus it is extremely easy to rip the connector of your PCB, and then you have a serious problem...
Don't worry, I've bought a OTG cable from China off eBay for 3 USD.
Hi all,
I am a newbie to the forum.
My tablet does not charge the battery. I open it and find that the motherboard only supply 3.74v, instead of standard 4.2v, to the 3.7v Li-ion battery. I examine the motherboard and find that a white part (in the middle of the photo below, opposite to the flat cable) was burnt. The white part is found in the charging circuit, giving power to a regulator before charging the battery.:crying:

Anyone knows what the burnt white part probably is?
Many thanks.

what tablet is it? make plus model number please
are there still any letters nubers on the part visible?
looks like a resistor to me probably a after release fix one because it's kinda big
I fried my charging port socket (don't ask -- coffee, I think). It smelled burned and the charger tip would get hot in the port. I bought a new charging port panel and properly installed it with the protective film removed from the bottom and carefully connected the ribbon cable. The phone will not accept input through the charging port micro USB, but it will charge on a wireless charger. Could I have fried the connector at the battery through which the plug-in power goes? Is there a separate circuit that inputs current from the wireless charger? Could that explain why changing the charging port circuit panel did not fix the problem? Should I buy a new battery and try that? Diagnostic help would be appreciated.
hi, when i take off the back cover to the left of the battery are three copper terminals and above the battery are 2 terminals. curious, what are they for ?
one is for wireless charging and NFC if you add a cover with a built-in coil and chip like the official Samsung s-view cover, can't remember which one is which but it should tell you in the manual that is on your phone
thanx. i wonder if there is a pin-out diagram detailing whats pos/neg.
What's your plan?
hi there.
those are the NFC connectors.
the usb charging connector is mash up. looking for ways to charge it ?
@schneidz just buy a wireless charging receiver (they are not that expensive, about 6 USD) and buy a wireless charger and you should be good to go
thankx, @ShaDisNX255 for now i cut a usb cable and stripped the wires and connect them to the battery (red -> +; black -> -) to charge for about an hour.
