I do believe that for the tab 2 to charge via your computer's usb port, it needs to be off.
Normal usb do only have 5volts to use. And the tab 2 uses more than that when it is on.

i asked myself that when i got mine.
it says "discharging" ans shows an "X" but in fact it DOES charge, but very veeeery slowly. you can leave it plugged for hours and you'll see that. i tend not to charge it via USB but if you will be on the laptop for hours its a good alternative.

my P5100 also doesnt charge from the laptop, same cable that charges from the wall charger i got with the tablet
maybe needs another special usb cable to charge from computers

Thanks for the replies

i remember reading on a site not too long ago trying to figure out this problem myself. they were saying that usb ports are like 500ma and since our tablets have a 4000mah battery. the usb ports dont provide suffient power even with the screens turned off. only way to do it was with the tablet completely off and maybe it would charge. i know when i plug mine into usb it wont charge, even with trying the little trick to it.

The manual states the tab will not charge via USB and the provided wall chargermust be used to charge the tab. USB ports dont provide enough power to run the tab and charge the battery.

Hi, You don't have the box ticked in the battery screen do you ?
the one that says
When device is turned on, do not charge the battery when connected to the PC
this should be unticked.
dean
Hi Dean
Now I dont have it ticked !!
Any other idea's?
The problem could also be your usb line or usb port. try some alternatives first.
Tried everything, different usb leads, different sockets even different laptops !!
Help
Same problem here. But i changed the USB cable and problem solved. Did u tried it, with the official USB cable from HTC? (I guess so, just to check)
Yep I did !!
Will try again when I get home though..
Thats strange... my TP came with UK power adapter, so I couldnt use AC power until I get an adapter (4 days)... in these days I always charged via USB (all night long)
Well I tried the official usb lead and it charged last night, Im now using the official lead again using same laptop and same usb port and guess what !!! It wont charge again
Have I a faulty touch pro?
shall i phone vodaphone and ask for a replacement

Hi,
this is sounding kinda weird..
What kind of wall charger came with the phone, mine is a wall adapter that i plug the USB lead into to charge the phone
So i know my USB lead works as this charges the phone with both the adapter and via USB on any PC ( i have tried home and work PC's)
Sounds like it could be a handset issue then ???
mine is a Vodafone handset that i bought unlocked and flashed with a different ROM and its working fine..

Laptops can be a bit funny about USB charging, I remember one laptop I had wouldn't charge my phone (SE K800i at the time), unless it was on mains power. The laptop had to be powered up while on the mains, with no USB devices plugged in, then it would supply power to the ports.
My work laptop is also a bit funny about it, I had to disable powering down of the USB ports otherwise it won't power them back up, but since if nothing is connected there's not much of a problem. There is also the possibility it's powering the port, which will charge the phone, but not enough power to actually make it worthwhile, you can check to see how much power is going to the ports by looking under device manager. So you might want to check it's not a problem with your laptop.

This is exactly what mine turned out to be. At work I've got a Dell Optiplex 745 tower and none of the USB ports put out enough power to charge my phone and have the phone on. I've got wifi turned off but the data, EDGE, is always on. If the display is on and I'm in Storage mode there's very little charging going on. It doesn't drain quickly but it definitely isn't going up. If I'm in sync mode it drains pretty quickly and it seems as tho it's not even charging at all.
What I do now is plug it in at work and turn off the display. Kinda sucks but I need my phone fully charged at all times.
I have the same problem....
the usb and the factory usb are different if u have looked carefully
firstable, the shape of the heads are different. secondly, there are 4 pins inside usb and 6 pins inside the factory usb...I guess that's the problem.
Try messing with the USB to PC settings. I know my TP was acting funny and not charging, and after i disabled network functionality, i think it started charging. GL.
Thamks for all the replys, if done everytjhing sometimes it will charge sometimes it wont, I have it connected to my laptop all day for internet sharing, it has charged up very slowly twive, and not at all 8 or 9 times, same usb slot , laptop plugged into mains, official usb lead used ( it never charges from another usb lead )
This is the 3rd htc Ive owned and the first to play up like this over usb !!

Have you tried it plugged into a desktop computer? It would rule out the laptop being the problem if it didn't work. You could also use a mini-usb cable, which could also prove if the official cable is a problem.
Having similar problem...
I'm having a similar problem. My laptop used to charge Touch Pro when i connect it. Now for reason i noticed that it doesn't anymore.
I could be wrong, but I thought I read in the manual that when the phone is synched to a PC, it only charges in trickle mode, so it doesn't recharge the battery efficiently. Is this the problem?
same problem here. Mine was working fine with ANY charger whether it be USB, car charger or wall charger. But now it will only charge with the htc plug but not the HTC wall charger. The plug is the one with the ports for tv-out, headphones.
I'm going to go try and do a hard reset.I dont understand what could cause this.

AC discharges instead of charging

Hello to all XDA-Developers and mortals
After years of using this forum and always being helped by just using the search function, this time I need to make this Post to hopefully get some help.
I have right now a touch Pro, with the original rom from HTC support site on my tPro. (Before it was several different Energy roms)
since a week my only chance to get my tPro charged is, using a USB connection cable since the original charger won't charge furthermore it discharges my device in less than e few minutes. I can actualy watch it sucking it out.
hase anybody an Idea what might fix this problem.
I want to (miss)use this post to thank all the chefs and developers that have worked on improving our everyday experience with our devices.
thank you all.
just go to start-->settings-->system-->battery and should say something about not charging on pc and you should be set from there

there is the option that says [do not charge over USB if conected to PC]
if I uncheck this one it won't even charge over USB, but my problem is that the battery is not charged with the original charger.

have u shut off the phone properly and take out the battery for like 30 seconds and putting it back in and connecting the charger? if that doesnt work, look for a spare USB cable sometimes USB cables give in at times, or look for a usb ac charger

Battery Charging with Red X?

I have just got my p6200 3g from malaysia. Couldnt be more satisfied. I feel like I just opened the only present I wanted on Christmas morning and its better than I hoped. Of course this came with an international gigantic 3 pronged charger adapter. I have (2) 2amp 5 volt adapters I was using for my dell streak 7. I tried them both and still get the red X. However when powered off, the device shows the battery charging animation. In settings menu it says battery state..discharging. I have ordered one from amazon due any day now, supposedly works with all versions of gtabs including 7.0+. Am I getting a trickle charge or is this due to not being a samsung charger? Im using the supplied samsung cable and outlet is capable of 2amps 5 volts.. please help! thank you!
the big 3 prong plug says 2.5 amp 250V? come on this thing cant need all that.. what does this batt need to charge??
##nevermind, I have the charger, just need the 2 prong USA adapter, hopefully I can find one. anyone have any ideas?
The red X is indeed due to not being a Samsung charger. Samsung tablets look for D+ and D- to be tied together and floating at around 1.2 volts or so. If they see anything else (such as the voltages that iPad chargers put on D+ and D-), they'll assume a USB connection and not charge.
Ebay is your best choice for these type of things :

To my knowledge, all Galaxy Tab variants use the same method of signaling a "dumb" charger. So any Samsung charger intended for a Tab should work - see my previous post for details.
thanks a lot dude. excellent.
Or get one of these

Plug it between the cable & any aftermarket usb charger, even the ipad ones, viola normal charging. Can even plug it into the computer for normal charging just a bit slower
hi,
i have the p6200 version of the galaxy tab plus, came with a usb cable and an outlet charger that connects to usb cable. when charging on outlet, it charges fine, but when i connect the tablet to my sony laptop, it says MTP instead of USB connection and there is a red X on the battery icon of my tablet, it's also not charging. how do i get my p6200 to charge on usb connected to my laptop? thanks!
I could be wrong, but i don't think it will charge via laptop usb.

It will and does. I've done it, it just charges MUCH slower and if you use it while plugged in too much it will drain at a slower rate than if you didn't have it plugged in. I was backing up my tab and the battery was at 50%, I plugged it into my computer and by the time the backup was done (nearly 16GB full) it was at 70% (took 2 hours)
Buy one of these: http://www.dealextreme.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
Set it to charge mode, plug between cable and charger (be it a computer or an otherwise not supported USB charger) and it will charge

My Galaxy tab 2 (GT-P1000) will not charge while it is on. I get the same charging icon with the red X. I am using the original cord that came with the tablet. Only when I turn off the tablet will it charge on the cord. The USB still works fine for connection to Kies. I just can't charge it normally. Any suggestions.
Also, I have been unable to sync my tablet so that my music, video, and pictures are available through the "video" and "music" icons on the desktop. I can play the files individually, but haven't been able to add them to the right library for these media players. What am I doing wrong? LOL

I believe you are asking in the wrong forum. This is the Galaxy Tab 7.0plus (GT-P62XX) area. You should ask in the GT2 section or the original GT forum (the model number you posted is the first Galaxy Tab). The fact that you have the product naming mixed up tells me you may have reading comprehension problems
Anyway. You are not being descriptive enough of your issue with usb charging. Are you using the Tab's charger? If not, it will charge really slow if at all (you didn't read this thread at all, did you?).
Also, You can't (AFAIK) play files directly off your Tab connected to a computer via MTP. It would have to be mounted as an external drive for the computer to use it as such.

[Q]Help please!!! Battery don't want to charge.

Hi guys...my friend gave me his Tab 2 7.0 in order to root and flash paranoid android on it...but now something terrible happens it won't charge...but it recognizes if it is plugged in or not...of it is off and I plug in the USB cable it loads the battery sign and shows me a battery with golden "juice" but than the sing disappears again...could you help me please? I read on a lot of forums that it's might just the cable but I can't test...he gave me just the USB cable... One thing I recognized is the phone showed me before rooting a litte red "x" in the battery all the time I was charging.
I'd be pleased to all answers.
EDIT: I've just cleaned the usb cable and the female input and actually it charges but it doesnt show not even on cm10.1.2 stable.

Did you try using another cable? Samsung stock cables are the worst. Most of the problems with my galaxt tab 2 and my girlfriend's s3 were caused by the faulty cable.
Just make sure there is nothing wrong with the cable or adapter you are using then go from there if it still won't charge.

Why won't my tablet start?

Sorry if this is the wrong board but I'm new to XDA :/
So one day I left my Versus touchtab to charge and then when I came back it wouldn't turn on. The problem is that sometimes when I plug it in the tablet would act as though it's charging but it wont so I run out of charge. My theory is that it didn't charge properly and it's completely out of juice. Please could anyone tell me why they think it's not working and how to fix the issue. Thanks in advance!
P.S It doesn't charge via micro USB and I've already been told to charge it via USB and it's actual charger many times!
