Hi.
I've just rooted my epad (having B70 serial) but I've noticed that when I plug in the USB cable to the computer, it won't recharge. Is that normal??

Yes normal. Does not charge with USB to PC.
ya its not so posed to fully charge but correct me if i am wrong i think that it trickle charges if it is plugged into a highspeed or a 3.0 port with the screen off

I believed so but I think you need a 3.0 USB cable also IIRC
You will get a trickle off USB2; not sure if anyone has tried USB3, I would think it can give enough juice to charge though. For meaningful stuff in the stikk USB2 filled world, use the charger

Hmm so nothing definitive then on this?
Could you use the keypad ports to charge?
If so would it matter which port you plug it in to on the Transformer?
Can the usb be used to transfer files to and from the laptop computer

do you have the dock? pretty sure it works fine with mine. wht rom/kernel are you using?
It will charge from the main adapter from a wall plug in. It will charge from the dock. It will SLOWLY trickle charge from usb if the screen is off.
No im on stock have b70 so no root. And no dock

Had it plugged into cable box usb overnight screen off no luck. Its like it only work with its own stuff
Sent from my SCH-I510 using XDA App
Yes...It really only works with its own stuff. Some have claimed to have it charge from usb when it was off but I have never tested it.
Are any other similar devices able to charge through usb? Netbooks or laptops? Usb was not designed to be a big power source. Some hard drives require two usb connectors for just a hard drive.

From what i have read in other threads it has to do with the voltage required and how Asus wired their plug.
Use USB 3.0 cables and it will work fine. Also use a USB 3.0 port on the pc for slow charging.
Usb 3 cable works fine here...

Hi,
I connect my TFT to an USB 3.0 port and the battery icon is not charging. Is it normal or ....?
Tks.
IIRC it will trickle charge when the screen is off. USB will not charge it like a wall charger would
Sent from my Transformer TF101 using Tapatalk
Yea its normal, bad design by ASUS
It will charge via USB 2.0 and USB 3.0 but you have to put the TF in sleep mode or turn it off and the charge is very slow

I charge thru my computer's USB 3.0 port.
Reading the manual, it says after charging the first time, that the tablet can be charged by USB if there is enough power through the USB port. I put an extension between the Asus adapter and the proprietary cord, and it won't charge unless directly connected to the adapter. I have USB 3 port on my computer that gives out higher than standard power, and I have a USB port in my car, and this tablet won't charge on anything except a direct single asus wire connection to the Asus adapter. Is this correct? It seems that I may have a defective tablet.
Are there any other people having this issue.
USB 3.0

The USB extension also needs to be USB 3.0. Is the one you're using?
The extension was to the power outlet in the wall.
I wonder if the Asus chord is made for USB 3 then?
Sent from my brain to my hand to XDA
Is your extension just a USB extension or a powered USB extension? Maybe it carries data but not power? Can you charge other devices with the extension (and do they actually charge at a decent rate)?
Yes! I charge my htc sensation on it all the time. But I more than that, I am trying to find out if others are able to charge via the Asus proprietary USB cord to another source such as a computer or car etc.....
as opposed to using the wall power adapter from Asus

I also can't get the tf700 to charge with any adapter other than the supplied charger. I've tried 500mA, 1A and 1.9A (from a Nook color) USB chargers and none work.

I am quite certain that it says in the user manual that it is possible to charge via USB, i don't have it with me at work, but can someone verify this.... it could be a major issue for some, and needs to be addressed. I know that the battery power at full charge is not going to last all day for me, and being able to charge via USB is really important since i am in sales so i do not have access to an electrical outlet, but i do have a USB port in my car.

I'll add my personal experience to this...
When I got the tablet I put in a basic USB extension cable between the tablet cable and the outlet adapter. I didn't notice for an hour or so that it wasn't saying it was "charging".
Except...in that hour the battery hadn't gone at all.
And with the screen off and left to its own devices it will charge to 100%.
So I guess the point is this, it may not say its charging but it is getting power. If you're using it as like an overnight charging thing, it should work just fine.
Doesn't the manual say that you need to power it off before changing over USB?

Thanks for pointing this out.
I'll have to check this out, but I hope one doesn't need to have to restart a tablet, just to change the power source. Kind of a pain

So maybe it is charging a little, even though it says it isn't. I think I will try this out and leave it for a few hours or overnight as a test.

So I plugged into the USB port and the power level was at 78%, I left it plugged in for about 5 hours and when i rechecked, it read 97%. The whole time it read as Not charging. This is good news, I really need that feature. It is interesting that it reads as Not charging, this must be a software error.

Sorry I thought you wanted to be able to charge your tf101 with a barrel plug, im not sure whether an adapter would work or not but i would recommend just using the stock charger it will be much easier and reliable

The note will not charge through the cable plugged into a usb. It will only charge through the wall plug provided. Not sure about the note as I have only had mine about a week, but I know on my galaxy tab, changing the kernel enables usb charging although very slow at charging.

I can charge my note via USB, but it seems to be much slower.
Yeah slowly charging.. maybe the capasity of battery too large.. but when battery full my note having long life..
Sent from my GT-N8000
Your note needs 2amp to make it charge at a better speed, it will charge via the pc but will take a long time due to the small amount of amp the pc usb port will give out,

Try pushing your USB very slowly in the port, it should show the charging sign once halfway through. Then wait a second and push it all the way in.
You might have to try this two-three times to master the art. I have a Tab and it works fine.
USB charging charges at a very slow rate.. turn the screen off and avoid using while charing and you should notice an increase in the battery % after a few minutes. A wall charger is much faster though, just grab a spare one on eBay/Amazon they won't set you back much

You are correct. Pc supplys maybe 500ma and tab charger is 2000ma. So on pc will take over 3 times as long.
