    Default Galaxy Tab 2: Won't charge when powered on

    For one reason or another my tab won't charge if the device is powered on. If I plug it in when it is turned on a little red X appears over the battery icon in the system tray when I check the battery status is continues to say discharging. But when I turn it off it will charge albeit very slowly. Any thoughts?

    Are you charging with the factory charger or through another charger or a usb port. Only the factory charger will rapid charge your Tab and charge it while it is ON. It will charge slower when ON! The factory charger can supply up to about 2 A, while a USB port or cell phone charger can usually supply less than 1/4 of that!

    Yes I'm using the factory charger. It didn't do this when I first got it. I noticed it started to do this an update. Not the most recent one but the update before that. I mean it isn't a huge problem. I just plug it in over night and most times it'll be charged by morning. It is just a slight in convenience that I have to set aside 8 or 9 hours for charging.

    When charging with a USB port I get an X on the little green battery in the bottom right of the screen. When charging with the factory wall charger I get a lighting bolt on the battery.

    That is what mine did before a couple of the updates. Now it's red X all the time.

    I'm having the same problem. I've had my tablet since May. It just started doing this yesterday--red x while charging when the tablet is On. I'm using the same factory charger that I've always used. I notice if I plug it in and unplug it and do that a couple of times, eventually it will start charging again. However, it always charges if I turn the device off. Very annoying. Do anyone know what is causing this problem and how to fix it? It seems to be a real issue since more than one person is having the same problem with the factory supplied charger.

    Angry Re: Won't charge when powered on

    Same problem. Galaxy Tab 2 7.0 inch. Using the plug it came with. Tried all wall outlets. Turned off all antennas. Blew out all plugs and connections. Reset to factory defaults. Still not working. 3 weeks old. Samsung support acts like they have no idea. They don't even cross ship. Taking it back to Costco - fortunately they have a 90 day warranty on Tabs. But very dissapointed in the workmanship and corporate attitude.

    The stock charger charges while power is ON and it's rated at 2A. My question is how come a 3rd party charger (from Best Buy), with a 2.1A USB power rating cannot charge the Tab 2.0 7" unless I turn power off? Is it possible that the stock charger supplies extra pins (or additional ones) so that the tablet can charge while powered?

    By the way, I bought the 3rd party one from Best Buy as the stock Samsung model has been on BACK ORDER for a while on Samsung USA's site.

    I've had the same problem, ever since the update to Jelly Bean. Samsung was completely unhelpful & internet searches futile...until I found the answer on YouTube, of all places.

    With the tablet plugged in to the wall, I pressed volume up and down at the same time & held for 10 seconds. Tablet reboots. After startup, shut it down. Mine started charging normally - FINALLY!

    Time will tell whether this is a long term fix...still have to check if the doggone thing will "talk" to the computer now - it wasn't doing that, either.

    Thanks
    Had exactly the same problem.
    soft reset didn't work, but pressing both volume buttons (no idea how that differs) seems to have fixed it.
    My Tab 2 7.0 now seems to be charging normally.

    the volume rebooy button doesnT work probably because you upgraded to Jellybean... you can just hold the power button then hit restart

    This is not helpful at all. This doesn't fix our problem. You have a different situation....

    Since I bought a Samsung charger, my SGT2 7" w/4.1.1 charges while powered. As a matter of fact, I cycle power about once a week unless I am flying. The rest of the time, I put it to sleep and plug the Samsung charger. Works fine.

    Unhappy Re: Won't charge when powered on

    I'm having the same issues. Even when I leave it on all night, it is still not charge. Never drop it, always taken good care of it, and I'm really getting pissed off with this tablet. I trust Samsung products, always have. But lately with this tablet I'm getting no where. I'm about to throw it away.

    Hmm... I am wondering why it works on some tablets and not on others? Could there be a quality consistency issue on Samsung's part? This Tab2 7" has been working flawlessly since day one (which is good). It replaced my ASUS TF300T not because it was better performance wise but that it better suited my needs being smaller and more portable. Last week, I bought a Nexus 7 for my daughter... almost handed her the TAB2 and kept the N7... but I had no real reason to do so as this Tab2 works great.
