Thanks to an article on makeuseof "HP TouchPad Not Charging? Don’t Worry, It’s Probably Not Bricked!" (jgfi - I'm a noob so no hotlinking) - I couldn't see any mention of this fix in any obvious place so I thought I should mention it.
Once you have made sure the charging port isn't wobbly and that you aren't using your mate's MK II Kindle cable by accident take a good look at that round charger. It's round because it unscrews...often by itself without you realising. So I unscrewed it, checked the contacts were clean and screwed it back together.
Before you head to the webOS support forums in a panic only to be told that you have to send your tablet back to the manufacturer (not a great idea, under the circumstances) there is still time for a level head. You see, unless your battery is broken (pretty unlikely in my experience) then what you need to do is unplug your HP TouchPad and remove the adaptor from the mains.
This barrel-shaped device has a twist-and-lock feature for switching plugs (after all, we use different connectors in different countries) and this can become slightly untwisted over time. The result of this is that your HP TouchPad receives a small charge, but not enough to recharge the battery.

Subsequently the "usb" part of the charger has been attached permanently to a cable leading to a normal 230v UK/GB mains plug. I won't go into too much detail how, as if you are qualified enough to do this part of the fix you won't need my instructions. There are a few other ways to keep the charger in place that I can think of, including remembering to screw it back together firmly whenever you use it and/or if it crackles.
My Touchpad now charges at something approaching post-industrial revolution speeds, and no longer sounds like the sound effects from an early Hammer Horror film. It also seems to hold a charge longer, and I diidn't have to spend money I didn't have on a Touchstone. Yay.
Apologies for attachments and broken links - still under 10 posts. :angel:
As a certified electrician, I want to reiterate that you should not attempt to mess with the charger (by attaching cables or some such) unless you absolutely, positively know what you are doing. (Props to stuff_it for not going into details). If you do, make sure you insulate everything properly afterward.

Thankfully my other half is well qualified to make a permanent fix, but there's nothing to stop the less qualified from simply making sure the two parts are screwed firmly together before use. It's surprising how much of a difference it can make.

I was unplugging my usb cable after flashing my phone and it pulled the pins and little charging thing out of my kaiser, now its just a hole with nothing inside, is this expensive to mend? basically it wont charge with charger or computer as there is nothing inside!!!!!!!!!! HELP!

Depends who you get to do the work (or if you buy the part and do the work yourself). If you review the Kaiser Service Manual (avail through the Kaiser wiki here on xda-dev), it provides part no details etc and shows you pics of what you're in for. All is not lost although it does make me wonder how pulling the plug *out* caused this problem - what is there to snag
Oh and most people will refer to that as the USB connector (whereas the charging block is commonly the thing you plug into the mains socket).
Please search XDA, this has been address in one way or another many, many times. Search for broken USB port. You can buy the the porst and try the impossible micro-soldering repair, or send it off and have it fixed. One service a lot of poeple use is http://www.ppctechs.com/ I think they charge $79 to repalce it.
If you want to see what is involved in doing it yourself; and why I will never try, look at post 4 here:
http://www.modaco.com/content/smart...hf-mini-usb-replacement-project/#entry1001118
I busted my plug and did not have enough to get it fixed, and there is not way I was going to try and fix it myself. I got a cradle with a battery charger from ebay; it even included an extra battery. I just leave one battery charging and swicth them when they die. It sucks becasue I have to take my back cover off every day; but it was only like $10.
Got an NC for Christmas and after reading all the awesome help on here got it rooted and set up the way I wanted it. So I plug it in night before last and it wont charge. Had to hold it at a certain angle then when I let go it would quit. I call B&N and they were gonna send me a cable. I said no the port is bad and I tried another usb cable and got the same result. So they are sending me another NC should be here tomorrow. I had barely 20% battery when I restored it to stock (which they told me to do before sending it back) or I would have been screwed. Anyone else had his problem? Also she told at first that another USB cable wouldn't work on it?? Anyone else use another cable or phone charger?
Thanks again for all the great info on here!!
All I know is that the mini-usb port on my NC -- where the charging cable plugs in -- is a mess. I have to insert the plug at a sharp angle and wiggle/force it, before it will go all the way into the port. (lame!)
On another note, the black plastic around the larger USB plug at the other end of the cable fell apart completely on the second day I had the NC. That end of the cable is now being held together by electrical tape. (even more lame!)
I'm considering an RMA for the entire unit to try my luck with a new one...
PS: performance wise, once rooted, this thing kicks total ass for $250!
Yeah, once mine is plugged in if I push the cable around it will stop charging.
I wonder if that Tear down gave us a reason for this?
After reading lots of posts over the past months it seems the port/plug is the most often reported problem .. I have two units and one (the first) is just fine, the other had difficulty with plug insertion but once inserted was fine. I tried the plug from #2 on #1 and yup, it was a problem to insert, so perhaps the B&N supplied cable is the problematic part, not the NC itself?
Saw that the EU has/will 'standardize' on the uUSB for charging .. personally don't understand ... it can't make that much difference in design/mfg and the miniUSB is very much more preferable to me .. sturdier it seems ... but it is what it is and I still love my NC!!!!

NC #1 that I got last Thursday had a fault USB port, as in I had a b!tch of a time getting the USB cable inserted, but managed it twice on Thursday for initial charge and a second time to try something sideloaded from Calibre. (Actually was about to return it as soon as I got it home and had trouble with the cable insertion until just as I was about to give up and pack it up, the cable went in...)
The next morning no amount of fiddling would allow me to insert the cable, so I factory reset and went back to the B&N for a horrid cs experience before they finally deigned to replace it. NC #2 the cable inserts MUCH more readily into...
Crossing fingers that nothing else goes wrong with #2. Ended up giving up on a pushed 1.01 update and sideloaded it last night, but first try was a phail, 2nd try went as expected. They need a user fw check and initiate fw update app as their OTA doesn't seem to be very robust or even work AFAICT.

Sounds like the charging port is a piece of crap. Still love the NC but I dread everytime I have to plug it in to charge it. Also when I plug it in to the computer or the wall the screen goes crazy and is virtually unusable. Read a few cases on here but no real explanation as to why.
As far as the update. Had to sideload it on both of the NC's i have had. Never would push it to it. Strange.
My first NC had a bad charging port. I returned it immediately. The second is fine.

Does your screen act up when plugged in? Mine does either plugged in the wall or the computer. Just curious how many people have this issue??
I haven't returned mine. The cable that comes with it is difficult to insert, but if I fiddle with it, it goes in. I have a generic cable that I use to connect it to my PC and it charges it, too. It may be slower and doesn't indicate that it is charging, but if I leave it plugged in all night, it is fully charged in the morning.

You do realize the NC (and most phones) uses MicroUSB, right? And actually MicroUSB is rated for more insertions and is sturdier.
The reason the NC's cable is a PITA is because it's not a standard MicroUSB, it has extra pins on each side to deliver the 1.9A of current that the NC charges at.

Great info. What I was wondering about. One question....will it hurt the NC port to use a standard micro usb cable to charge or connect to the computer?? I did on my first one and thought that may have been the reason it went bad.

I would not think so, in fact if that were the case I'd hope B&N would have had the jack not fit normal MicroUSB cables, but who knows.
Also B&N knows users aren't going to unplug the cable from their charger and plug it into their computer.. At least a reasonable number of users won't do this, although I might be the exception having a MiniUSB and MicroUSB dangling out from under my monitor for plugging in stuff
I've plugged mine into my computer numerous times, no problems so far. It does charge from any USB source, albeit slow.
On the new one. No.

Yep. #2 has that problem while #1 did not. I notice it on #2 as soon as I had gotten home and had it charging and was trying to do the setup/registration... It was an exercise in frustration...
I'm going to be letting #2 discharge today, then do a full charge and carefully track how much time I get off the charge since I've read a battery runtime thread on the B&N forums. (Very low backlight & WiFi off.) Might need to return #2 for battery problems as it seems very short to me although I have not been keeping careful track of how long I've been running between charges...

It is very frustrating! Guess will just have to quit using while charging. About the battery, are these like the new phones where you can just charge them each night? I do this on my Droid X just wondering if it would hurt these batteries?

I have this problem. I believe this is caused by the AC adapter. I went to my local B&N and hooked up my nook to their charger and had no problems. I called B&N support and explained the problem to them. They said they would send me a new AC adapter which should have arrived yesterday. It hasn't arrived yet but I think that should fix the problem.
I also have a problem with having to insert the micro usb in at a funny angle, but once in it charges.

Think I will call them as well. Just to calm my OCD.
Yeah I have insert my USB at an angle as well. Once there though it is fine.
Would like to know about the battery though as I stated in a post above.
My sister bought one on Monday with a bad port. She took it back and got a new one.
BTW - My sister so liked my rooted Nook she went and bought one. She came straight to my house to have me root and install apps.
My 'charger' I'm using is nothing more than cutting the end off of a usb cable, stripping the red and black wires bare, and twisting them so the strands are tightly twisted. Then I carefully stick the red into the positive pin slot of the battery and the black into the negative. I then insert the battery into the phone and snap the cover on. Plugging the usb into a charger makes the phone think it's fully charged so I can flash.
I just wanted to put this here in case anyone has a low battery and needs to flash. If anyone needs more info/help let me know.
There is a special cable you can get with special wiring, often referred to as a Motorola factory cable, that can power the phone through the regular charging port instead of using it to charge, and that can also be used for basically the same purpose as what you did. There are multiple places online to buy these. It is another option for those who don't want to modify cables themselves.
I should get one of those as we've still got this Bionic and a MotoX in the house.
I was considering posting some warning about that cable, but found this page I'd previously read with various precautions and warnings and other info, I think written by the person who released the schematic for the cable: http://www.shop.teamblackhat.info/Factory-style-programming-cable-for-Motorola-FactCable.htm
There may be more phones it works with than those listed, but personally I'd only use it with ones people somewhere have reported that it works with.
Hey all,
Before I even start here, please no snide replies about using the search box on here or anywhere... if the answer is out there, I'm at a loss for the keywords to get it. Fair enough? As FYI, bootloader is (was??) unlocked, rooted, and has cwm recovery.
So I dropped my MB886 cracking the screen (round of applause please) and in the process of disassembling the case to install replacement I tore (severed) the battery connection cable. Fast forward to phone now reassembled with new screen and battery installed --> -->
The phone now has a green LED that will respond with blinks to button certain presses i.e. the simulated battery pull, but the device doesn't show up in lsusb output or device manager. I've read of similar problems where the phone has been brought back, and I've read of the exact problem with no solution. Basically the only two things I've really read that supposedly work are battery pull button sequence and using OEM charger/cable to get battery to take a charge.
Unlike, say the Atrix 2 where the lonely white LED is there to serve as a reminder that it is a hard brick and that's all you're ever going to get from it again, I haven't even read that this is in fact the #1 sign device is now a brick. So could someone verify it is or isn't? I've never tried to access a device this way, but Is JTAG an option?
I don't get why this should be, despite battery issue, it's all simple hardware swapping involved here as the software wasn't touched and was 100% working even with cracked screen.
Thanks for anyone with an answer or the direction to one.
2 things it could be then: you over- or under-tightened the new battery cable screws to where there isn't a good connection with the board. The screws have to provide equal pressure on the positive or negative contacts or otherwise there's a fault in the circuit.
OR
Your new LCD/digitizer is defective OR wasn't seated well.
Since it was working before, and since you didn't break anything else (to your knowledge), those are the two things I would check.

hey, thanks for the input. I remember battery connections being snugged when I originally took it apart, and to be honest, short of having a mini torque wrench I don't know I could put them back any closer to that. the digitizer could certainly be either defective or perhaps have a bad connection, and i am certainly willing to test/check for either, however do you know that this would prevent the phone from booting or cause it to only display the green led as a sign of life? something of the "halt on all errors" in pc bios? seems logical that the led would (or could've) been used like the oc speaker and blink out some code relaying you've got a bad O2 sensor or the gas cap isn't tight.
Over tightening can cause problems. So loosen them a bit if it's just-short-of torque wrench tight. I don't know why it does, but I've read people had problems when they over tightened those screws. That green light could be telling you that the battery is connected poorly.
Is there a possibility that the battery is so depleted that it won't charge? For that, you need a factory cable to charge the battery with power off.
Sorry, to clarify, no I just snugged the battery connections when reassembling, I only meant that i don't think i could get them any closer to the way they were originally without aid of something like a torque wrench.
As for battery charge as a potential issue... to be fair, I only have a OEM Moto wall charger and I think the cable I am using is Samsung. Surely the cable itself isn't the weak link in this chain? A car battery on a multimeter reading 12.0 volts is something like 50% charged and about 12.8 volts is looking pretty good, anyone know what I should get out of the 3.8V Li-Ion on a meter?
PS I double checked the both data cable connections to the motherboard, so I doubt just a bad connection is to blame here.

When I say "factory" cable, I'm not talking about the cable that came with the phone. There is a special Motorola cable (that you can even make yourself) that can charge your phone in situations when your phone is normally not willing to accept a charge.

Scratch my previous answer. Seems I misunderstood what a "factory cable" is for. It can't actually charge your battery, instead it is used to power the phone so that you can flash/diagnose it, even when your battery is dead. Normally, you need a working phone to charge the battery (with the stock "charging cable").
This information may or may not help you. At the very least, using a "factory cable" may allow you to power your phone on, which would tell you whether the problem is your battery or the phone.

well, i'll take it regardless... i've acquired one of these mythical factory cables and it gets me into fastboot and recovery, so i'd wager, even though i haven't seen it, that it would boot all the way. so being that i don't have either the original charger (although have one that's motorola) or cable (samsung), my best bet is probably just find a store that has both an OEM motorola charger and cable even if they're not for the MB886? surely one for a moto x would work to charge battery, no?
or is this like a chicken and egg problem i now have? a catch 22? i can't charge the battery without a working phone, and i can't have a working phone without a charged battery? golly gee, anybody out there with an MB886 want to charge my battery for me? can i just hotwire the battery to a couple of leads from a charger and bypass using the phone as the charging device? at least to give the battery say 15%-20% to get something to happen... like get this rain cloud perpetually parked above me to blow over from above my head for a day or two maybe?
so, with phone plugged in with "factory cable" here's what i get and when... the phone bootloops on the "bootloader unlocked" warning screen if i don't press anything. volume down gets me fastboot, volume up gets me recovery. phone shows up in both and takes commands... so is it possible i just need to restore a nandroid backup, or is the battery charge the better bet now? i would just try the nandroid for $h!ts and giggles, but the last one i have isn't as fresh as i'd like, but is certainly usable if i must.

Any generic USB charging cable SHOULD be good enough to charge and flash your phone, especially a Motorola cable. I'm currently using an old Blackberry cable for everything. They should be all the same. In rare instances, a cheap cable may give you issues (I think I had a cable from an old Samsung phone that I couldn't get to work right).
I guess just keep trying until you find one that works. Hate to tell you to go spend $20+ on an official Motorola charger...
Regarding your battery, yes you may be in a bit of a pickle. I've never had to do it, but I've read of users who had to short some leads in order to directly charge the battery. Trying searching through the forums, I'm sure the info is here.

All hope is lost, I am now looking for a replacement.
Ok, so here's where I am at with this now... As we're basically talking about any regulated power supply that can put out an excess of (around) 3.8V and 800mA I've opted to use an old ATX computer power supply and wired the mini B USB end of a cable known to have in fact to have charged this very phone... nothing. I have also, for sake of hope, even tried using the wall wort from an iPad (which puts out a cool 5.1V and up to 2.1A). The green LED will shut off after a while of being plugged into said charger, but still no booty action.
As stated before, the phone still works with the factory cable.
So, I gather from this that...
A. some hardware component (i.e. resistor, etc...) on my phones board that is involved in the charging process has gone kaput.
or
B. There is some software flag flipped somewhere that could be unflipped with or without some trickery to what actually is VS what I want the phone to think it's seeing.
Anyone have any thoughts on this or something similar pertaining to B as a course of action?
*update to my update* ... umm, which should now be up to date??
I did a complete wipe of the phone (/system, /data, /data/media, /cache, and /dalvik-cache) and reinstalled the rom... and still nothing.
So i was soldering up a extra long micro usb cable to the other day to power a cheap ip cam i had. Being the lazy git i am i didnt bother to check the polarity with my meter when finished but just blindly trusted the embossed + and - symbols that were on the micro usb plug i used. Tested it on my ipcam and it didnt work (didnt break it either considering its cheap nasty chinese trash) so lazily got a second opinion from the closest thing to hand (my z3 compact) and now its acting kind of broken. The cable did indeed have reverse polarity
Ive had the phone 2 years and its always been very reliable. The phone instantly went off and would only come back on again with power/volume up. When its on it works perfectly, no glitches or anything and seems to charge/discharge fine but will randomly reboot quite often now and battery charge will suddenly disappear. was just looking for an opinion on how buggered it is from someone in the know. Could it just be the battery buggered, is it worth trying to fix?
For the sake of £5 ive ordered a replacment battery and will hope for some luck.
Many thanks.
Looks like i overreacted. Did a fresh install/repair from PC and seems back to its old self so must have been a simple corrupt file/s caused my instant shutdown protecting itself from the cable :/
