guys, I am having this problem from day 2 of having TF. First day was charging fine. Second day I had to play with the wire and reset the device then it charged. Today, NO CHARGING AT ALL!!!!
I tried to the piece that goes to the AC out , but still nothing happening. I connected to my PC, and it recognizes the TF and I can view its files, but with no charging!! Is that normal or what??? Does yours charge when you connected to your PC?? What should I do? Should I call Asus? if yes, what number? or should I return it to Best Buy.??
Help, please ....
I don't think the TF charges when connected to a computer but others have said it does but at a very slow rate. I've heard others say it does slowly only w the screen off as well.
It sounds like you may have a defective charger or charger port on the TF.
Do you have any other USB AC plug adaptors you could try? I know many of them don't put out the same power but may be worth a shot.

I tried a different USB AC plug, but no luck. I guess I am going to return it to Best Buy.
You need to make sure your using the USB cable that came with the TF and the outlet device that came with the cable/TF...
The TF charges at a higher rate than USB from the PC. So, the TF uses a USB 3.0 cable (included - most cables purchased are USB 2.0) which had more pins and allows for faster charging/higher charge rate.
Using the computer will only "trickle" charge. Using a USB 2.0 cable with the TF setup will prevent it from charging or only "trickle" charge....
I did not use any other cable or outlet device beside the one that came with the TF.
It seems it only syncs, but it does NOT charge !!!
I took it to Best Buy they said we can refund the money to your credit or choose another tablet because they don't have it in stock.
I don't want another tablet. If I had to, I will go to iPad 2
3 days now and I am having no issues at all.
I called ASUS, and they said its from the adapter, and I can not use any USB adapter like apple's. So, they want me to send it back to them, and they will do diagnostic at everything and will return it to me.

Okay so my usb port has been a bit annoying the past week - where i had to vigorously wiggle the cable to get it to charge or to sync (and even when it did decide to connect to the computer, it would chop out eventually)
But now it's no longer charging or being recognized by my comp
It's strange because the headphone adapter was working fine, and so was the usb host, but it just wont charge anymore - I effectively now have a dead TG01
Currently, i'll get the orange light, telling me it's charging, but when i try to power on, nothing happens...
So i'm thinking a new USB port which is where I need some help: I'm not sure on what part to get
But maybe This is the one? Comparing the images with the ones found on the net of the TG01 (Yep - I still haven't got mine open yet)
But yeah, just a heads up on whether you think it would work would be epic, or whether you think i should just try a different battery/charger/throw it away (Although i'm almost certain it's the port, as it was working intermitently before - it's now gone altogether)
are u using only usb to charging or an wall charger?

Wall charger, but i tried USB, and still no luck
It just wont charge at all, regardless of the orange light when plugged in now that it's off (though i wouldn't get it when the phone did still have charge left and was therefore still switched on...)
BUMP: Any ideas you clever people? Just some guidance would be nice...
I'm still without my beloved TG01, I'm having to use a **** old Samsung G600
I do have some problems of my own with my USB cable. I believe the problems are due to the cable, though. The wall charger works fine. The USB cable that I use, has to stay somehow "forced"... imagine having the cell laying face up on a desk. The USB cable gets out and is forced by a small pen that stays right near the cellphone, to have a 30% slope upwards, so pushing a bit the cable onto the upper part of the USB port. I do know that you are telling us a different issue, however, maybe this way you could check whether it's just a broken connection and not a completely dead port.
No, this sounds like the exact issue i had...
It was like this with the Charger and USB - where i had to force it to be recognised or charged, and it would still cut out after a while - and wiggling it or knocking it wouldn't actually affect it, it would be of it's own accordance...
But it was strange because the headphone adapter worked fine...
Nothing happens at all now though
Are you try: Settings- Connections- USB to PC- unmark Enable advanced network functionality
I can't turn the phone on because it wont charge, so it's not that
Battery may be defective. Try with any 5V charger, connect directly to battery pin in 10 min
Hi
It vaguely remembers me of something I read on the forum about different micro usb (explaining my different cables do not connect just the same, some easy, some bit forced); I think there also was a drawing. (but I don't have time to search for the exact thread; it was not the "solving usb port mistery one))
Maybe your earphone adaptator don't have exactly the same as your charger? And if it is not battery trouble, find a charger with the "very right" micro usb plug?
Thank you both so much for your response:
I understand why you say it could be the battery problem with the charger - but it doesn't explain the intermittent connection with my computer when using the USB cable. Which is convincing myslef more and more that it's a port problem
One solution for now would be to buy one of these cheap external battery chargers from eBay, but it would mean i still wouldn't be able to use sync using the USB cable and i'm a bit conscious on whether the charger is safe and wont fry my battery
Which is why i'm leaning towards having a stab at reparing it myself
It'd solve the issue directly and it'd be a safer and more secure solution too... (the external charger would have to be ordered in from Hong Kong eBay)
I'm having what seem to be exactly the same problems. I have used 2 x usb based chargers on it - and neither work (whereas they had been working for the past 6 months). Got a mains charger last week - was working for a while - but as of right now, no longer works.
I'm not sure what else to do. I will try later to use the other adapter I have for connection to usb keyboard. The strange thing is - this will probably work but charging won't!
So....is it the micro usb port that's broken? (strange if it is but still works for data)
OR
could it be the battery?
So, I'm traveling (for a long period of time) with my TF. One day, it stopped charging.
I took apart the power brick and put it back together, I even tried to freeze it (on advice from some older "not charging" threads), nothing helps.
When I connect the TF to my laptop via USB - it recognizes the TF. When I connect my iPod to the power brick (with its own cable obviously) - it charges just fine. So what broke?!
I hate this, the local stores here don't sell the power brick separately and I don't even know if that's the source of the problem.
This sucks
Sounds like the power pin in the TF port has bent/broken or just has some detritus/dirt/foreign matter in it and is stopping it from charging properly. Have a look, but you might need to check the port with lots of light and a magnifying glass, so not easy while you're on the move.
If you are in the US Office Depot sells the charger and USB cable for $30.
strange thing is that sometime my transformer doesn't charge.
i have to reboot and it start to charge again.
Same happened here. Asus tech wanted me to wipe the device. After trying other options to get it to charge, I did but it didn't wipe... Go figure... But it booted up normally and now it has been charging.

Apparently charging has some history of issues on the TF101.
I just had mine act up on me, went around the house trying different wall sockets and checked that it worked fine via USB to PC. Ended up taking a can of dust-off to all the pins, then shoving the plug hard into the TF101 socket. Now it works.
Should have mentioned I have a dock as well, which doesn't charge either (so problem is probably with cable/brick)
I'm trying to get new ones (nowhere to be found here, but I'm trying to get one sent to me). I tried looking for dust/dirt and different wall sockets, no luck.
Weird thing - I left it plugged in to the wall overnight and it grew from 5% to 15%, so looks like some electricity is trickling.
I had the same problem with mine after I had it for 5 weeks, I just RMA'd it and everything is fine.
Im having the same exact problem. I left it charging over night by mistake the night before yesterday. I only let it charge 3 hours the most because I know the Transformers have known issues.
I tried to charge it this morning and nothing. I plug it into my PC. The PC recognized the Transformer but no charging. Turned it on and off, nothing.
Just put the power brick in the freezer, waiting to dry up to see if it works .
Although the tf charger and cable has a usb connector it is not usb compliant. the charger brick looks for a gnd signal on pin 7 of the usb connector ( normally a usb 3.0 data line) to determine it should supply 15V to the positive charge pin vs standard 5V. The slow charge you are seeing is from the 5V supply . check to see if pin7 is seeing the gnd signal. Are you using a usb 2.0 extension cable as it doesn't have have pin 7 conductor. be careful connecting your ipod as it could accidentaly see 15V vs the 5V it is designed for.
My Photon Q won't charge off a PC USB port, or my laptop. Is this common? Thanks.
Are you using the usb cable that came with the phone? Reason I ask....I've discovered this phone is extremely picky about the cables you use. So far of the ones I have on hand, I can only consistently charge while in the car using my Belkin usb charging adapter with the Motorola cable that came with the phone. That includes a fairly nice ferrite core 6ft usb cable I got from Monoprice...which it works fine at home on AC, but in the car it stutters back and forth between charging and not charging.
Just today I used a cheap USB cable I bought off of ebay to charge my PQ using my laptop.
Its one of the ones sold as "HTC OEM USB Charger + cable" on ebay for like 3 bucks.
I also charge it at home using a green 3m cable from ebay, also bought for like 3 bucks lol.
Does it require that drivers be installed on the PC to get a charge? I've tried a few cables that I have laying around. I'll see if I can find other cables to try. The weird thing is if the phone is off, and plugged in, the LED lights up green, as if it's charging. But using the same cable, if the phone is on, it won't acknowledge that it is plugged in.

No, I wouldn't think so...
I've been able to charge off of many different USB cables on my Q. Not sure... Only thing it's been picky on so far is the wall wart - cable it hasn't seemed too picky about.
If its an old desktop with USB 1.1 it may not charge, and many laptops won't allow charging via USB if the laptop itself is not plugged into AC. Just a thought.

Very good point ^^^. I've heard some laptops, even when plugged in, still don't provide enough juice to charge (some) devices. Perhaps your laptop is one of these low-power USB port devices.
ive noticed that this phone is picky about what charger you use. i have a hard time charging on my pc as well. and certain micro usb's i have dont seem to charge it well either. needs to be the stock plug it came with.
I've basically given up at this point. Blackberry AC chargers work well for me, so I'll try and track down a few more of them. Otherwise, nothing is consistent. The desktop I've used has a plenty big enough power supply, and it charges my Epic with no problem. My personal laptop and work laptop both charged the Epic, but not the Photon Q. I guess I'll just have to carry around a charger instead of a MicroUSB cable when I'm on the road with my laptop.
Thanks, all.

All,
For what little it's worth, I just noticed that the words "Not Charging" come up on the lock screen whenever I connect to the USB port of my laptop or desktop. So the PQ knows it's plugged in; it just refuses to accept the charge.
Also, whenever the battery completely dies, the phone will start to charge. It will charge for a few minutes until it has enough battery to turn itself on. As soon as it turns on, it stops charging, and a minute later, shuts down because of the dead battery. Then it starts charging again. This basically gives me an endless loop of the phone charging, starting, discharging, and shutting back off. I can't even get it to stay off long enough to get a useful charge without turning on automatically.
Yeah, the only issue I've had with this phone at all is the extreme 'quirkiness' it has in regards to charging on anything other than the stock usb cord & power adapter it plugs into. Even using the Moto vehicle dock for the Q, its completely hit/miss on charging. It will *often* go into that 'Not Charging' state where its kind of keeping sort of a baseline/'stalemate' of the current charge level for me, not really going down but not charging back up either. Not really sure what's up with that. With my vehicle dock for the longest I kept thinking maybe my cig lighter port on my car is bad, but I don't have issues with my radar detector at all.
Had the same problem with the not charging a few days back. I was leaving the phone in Mass Storage mode because just getting it into Mass Storage was a headache originally.
Hooked it up to it's original cable and woke up with 65% battery. Switched from mass storage to charge only and it started charging.
Not sure if it was caused by being in Mass Storage and wouldn't charge but now I put in Charge Only before bed.
It always works (in my experience) with the original cable that comes with it regardless, its anything else where its quirky.

Isn't there a setting in ##3282# that enables and disables USB charging? Y'all have probably thought of this already. Anyways just thought if throw that out there. This is my first android that was not a low usage device. I know very little about it. I seriously think xda should make tee shirts that say "everything I have learned in life I learned from xda".
My phone was not charging in debugging mode yesterday.

Hi everyone... I have an asus tf700t and I was wondering if I can charge it using the belkin mini surge protector with usb charger ( w**.belkin.com/us/p/P-BZ103050-TVL )? I just wanna make sure if it would be ok plugging the usb cord straight to the usb socket of this belkin usb socket. I carry a lot of gadgets with me whereever I go so I kinda feel that it would be bulky carryng a lot of chargers for my cellphone, laptop... etc. Would this be safe? I just experienced last week someone's charger got toasted using a public wall socket using the original charger. Thats why I thought of buying a surge protector as well. Thank you.
Depends on what you mean. Do you mean skip the Asus wall plug and use the usb ports on this protector? Then the answer is no. The usb ports on any device you use to charge the tablet needs to be usb 3.0 and supply the needed 15v of power. All of the usb plugs that are sold are made for 2-5v devices. If there is one that does supply the 15v then I have not seen it and many people using this forum would probably love to purchase it. You've stated one main reason to buy something like this, limiting the number of plugs to carry around, but it's also like $40 bucks to buy another plug from Asus.
That 2-5v is enough to charge cell phones, gps units, apple products, other tablets that don't use a proprietary power plug, etc. It may supply a small trickle of power similar to hooking up the device to a computer while the tablet is powered off. That would take hours to charge the device and not what you are looking for. I think one of the advantages Asus went for in using usb 3.0 and 15v is the speed of which the device can charge. It is pulling more power and able to delivery it to the battery faster. That is my guess but it is limiting our after market choices.
Now if you mean use that as added protection and have the Asus plug plugged into it, then yes it will work. If you are concerned about pulling too much power through it then don't have the device hooked up to it and use all of the other ports on the protector at the same time. That little device does seem neat. I lost an a/c adapter for my laptop when lightening struck really close to my hotel. Fried the power brick but luckily the laptop was not damaged. At work and at home I use a power strip/surge protector when plugging in the tablet to charge.

Ok tnx for the input. Just wanted to be sure if it would not harm the device if I use the usb wire without the charger adapter that came with asus but rather plug the usb cable directly to the belkin usb socket. Being stated that the tf700t is usb 3 and 15v is needed, will the belkin suffice to charge the device using its usb slot for charging without causing any harm? The spec says in belkin mini surge protector is 5V/500mA each usb port.

It should work and do no harm, but it will be very very slow - maybe 5% per hour...

One correction please. Its not usb 3.0. Its just usb 2.0. Check for the specs on asus site.

It's a USB 3 plug, and the additional lines are somehow used by the Asus charger for detecting the tablet and switching the voltage.

Oh! I was talking about the tablet. If the tablet had USB 2.0 why would the plug be of USB 3.0.
Hi I noticed a while ago that pin 30 on my charging port of my tablet was lifted some so I pushed it down with a toothpick. There wasnt an issue with the tablet before, it was just something I noticed. I ordered a cable from ebay, probably a knock off, and it worked for both charging (with the use of the p1000 adapter) and for data transfer. I was using the tablet mostly for debugging and movies. I recently had it charging for a while using the rocketfish usb hub and the p1000 adapter. I tried to plug in my tablet to the pc with and without the adapter and my pc was telling me that it had an unknown device plugged in. I looked up what exactly pin 30 was and it is a ground pin. My question is would that pin affect the ability for the pc to data transfer and recognize the device? The cable currently only works for charging and that is with or without the P1000 adapter. Other than that it gives me an unknown device when plugged into the pc. I dont have another tablet or cable to test so I may just order an official cable and charger if the ground shouldnt be an issue.
Have you installed Kies? Windows cannot recognize samsung galaxy devices without it
My cable stopped charging all together. I ordered another data cable to see if my original cable was faulty. Hopefully that was the problem all along.
I got my new cable in which btw is alot more sturdier than the last. I plugged it in anticipating an error and behold! My pc recognized my tablet and began to charge. The data part works because it instantly showed that the tablet was in debug mode. So my pins were not a problem, just my cheap chinese tablet cable. P.S. I did not have to install that software and if in the future I come across a problem then I will try out the software. Unless there is a benefit to installing the samsung software? feels like an iTunes type of software. Thanks for the suggestions and hopefully this will help others in the future.

Thank you for posting your fix for your question. It drives me crazy when people ask a question. Then later reply nvm I figured it out. (And don't explain what they did) or not even reply at all.
I think I have same issue. My stock cable won't charge anymore. Do you have a link where you bought new charger? Or what store did you go to?
I ordered one from amazon and it was a knockoff that gets a red x over battery icon :/

No I order this combo kit with wall charger, car charger and 30 pin USB cable. From amazon
Weird cause the car charger works amazing. Can watch Netflix w/ full brightness and still charge. While the wall charger will only charge if shut down
But about original charger. I was mistaken. I had a 6ft. Extention cord that I would plug it into cause original cord is way to short. And come to find out it was the extention causing the issue.
But I'm still interested in a Spare wall charger that actually works. Lol where did you get yours. Is it just as good as stock

Well technically the extention cord isn't putting out the same amount of amps as the wall outlet. Especially when the gauge of the wire is way smaller most likely. But I like to use my tablet while charger and refuse to 3ft away from wall so its kinda neccessary lol
