Stupid thing stopped charging :(

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.

[Q] Keyboard/Dock Charging but not being seen by tablet.

So I've searched through the other forums and haven't seen my exact issue. I'm running cromiX 4.7 with hunds kernel. Last night I was playing Dungeon hunter, when I noticed my dock/keyboard was no longer showing in my notification tray. So I rebooted, tried to reconnect it etc. No luck, the tablet still wasn't detecting it. So I began troublshooting. First thing I did was go plug it into the charger, the led came on so I know it's getting power. So to verify the port was working I plugged in my tablet to the dock and plugged it back into the charger and it began charging my tablet and dock, like I do every night. So I know there is power and I know that the port is functioning. I reloaded cromi, and tried a different rom and the dock still isn't being detected. Has anyone encountered this issue? Thanks
EDIT: Upon further inspection I noticed, that when the tablet is docked and charging cable attacked the LED on the tablet and dock lights up but the tablet is NOT charging, even though the LED charging lite is on.
FIXED: So i decided to dissassemble the dock (Very easy) and removed all cables and hinge, checked for scorch marks etc. Once everything looked good I reconnected all cables and verified that they are secure. Upon reconnecting my tablet, I found that the tablet once again was seeing the dock. So no surprise, ASUS just built a crummy product, great idea just poorly designed. Hope this helps others.

Is there by any chance dust or dirt in the Tablet's charger port?

I took an esd brush and cleaned out dock port and tablet port and took air compressor to blow out any debris, no luck.

[Q] Sudden charging issues.

I just picked up a used TF300T on Craigslist yesterday. It was completely stock, running 4.2.1. When the lady handed it to me to check out, both the dock and tablet were fully charged and everything was functioning normally. It wasn't til later that I tried to charge the tablet/dock that I noticed the dock wasn't taking a charge, but the tablet was charging. Eventually, the dock battery went down to 0% and that's when things got worse. Now, neither the dock nor the tablet will charge. Even when the tablet itself has the cable plugged directly into it, it still won't charge. No matter which port I plug the cable into, my PC recognizes it and mounts internal storage; but the stupid thing won't charge.
I've since unlocked the bootloader, installed the latest TWRP, wiped data/factory reset, rooted, etc. Nothing has made any difference. The fact that everything was fully charged up seems to support the original owner's claims that she never had any issues with it. I just don't understand how it could be fine one minute and suddenly have issues once I take possession of it. I'm pretty anal about caring for my gadgets, so it didn't suffer any bumps or any kind of mishandling in the 24 hours that I've owned it. I'm at a loss. Any ideas?
The only activity I've seen from the dock's charging LED came after the dock was fully discharged. Now, if I have the tablet docked and the charger plugged into the dock, the LED blinks orange. I've never seen the LED do anything without the tablet docked. No idea if that's significant, but thought it was worth mentioning. I did some searching and found that some people had charging issues with their docks, but didn't stumble across anything that seems to match what's happening with mine.

The USB cables have been known to go bad, and regularly at that. The wall wart's quality is stable, but you can never tell. Now if you plug the cable to the dock and it blinks orange, leave it for a few hours. If on inspection, it persistently shows 0%, that means 2 things: either the charging port soldered onto the mainboard is kaputt (unlikely if the charger charges the tab through the dock); or the I/O controller chip (Nuvoton781) has gone AWOL (this is situated on the back of the dock's main board). The inner circuit that burned the charging part still allows for other functions such as USB and SD card and keyboard, and give you the false impression that ube alles, just for the fun of it. But don't be fooled. It has died.
If you plug the cable directly into the tab and the (a) the led shines solid orange, it means the charging circuit is good; or (b) blinks orange, it means it's charging but the battery voltage has gone too low for the tab to be useable. Normally such situation requires at least a few hours of charge. If it don't do nothing, again either the charging port (cable) has gone bad, or the cable and/or brick are. One time I plugged the cable in upside down, and accidentally forced it a bit, which resulted in my bending 2 pins inside. Had to replace port. So use a loupe and look inside all the connectors to make sure nothing has been twisted out of place. It might be tedious work, but since you're anal, you might enjoy it (lol).

Your tf300t will not charge from your computer. You need to get the USB adaptor to charge it. The Blinking orange light usually means you have an empty battery.

Thanks for the response. It was thinking along those lines that ended up leading to me figuring out the issue.

While not entirely true, my issues are actually along those lines. The TF300T actually will charge from a PC's USB port. It just charges painfully slowly. From what I've been reading, unless it's connected to the correct power adapter, it'll trickle charge, but the system doesn't know it's being charged and the LED won't acknowledge the trickle charging.
Well, after more panic-stricken reading, I figured out the problem, and it was comically simple. Apparently, neither of us had noticed that the lady accidentally gave me the wall wart (adapter) that came with her Samsung 7" tablet. It was when I was inspecting all the various connection points that I noticed the adapter said Samsung on it.
Apparently, it's as simple and stupid as the 5V output from the Samsung adapter being too weak to properly charge either the tablet or the dock. Oddly enough, it'll trickle-charge the tablet, but doesn't seem to do anything for the dock. Until proven otherwise, I'm gonna be optimistic and assume that, once I have possession of the proper wall wart, it'll charge normally. Can't wait to find out.

TF300T stays at 1% & will not charge

I recently picked up a used TF300T with a shattered digitizer. I managed to successfully remove/replace it & the tablet is working fine.. except for charging. It turns on and says the battery is at 1% and needs to be charged. When I plug it in to charge it, it doesn't charge(just stays at 1%).
It came with a genuine Asus USB cable & what appears to be a generic USB wall charger. When I connect the tablet though, it registers and the screen comes on. When I plug it into my PC it also comes on and registers(so I know the USB cable and charging port on the tablet are fine).
I do have other tablets(iPad 3, iPad Air, Surface Pro 2, etc..) and tried using the wall chargers that came with those, but still no luck.
I'm assuming then that I have to use an actual Asus wall charger meant specifically for the TF300T? Or do you guys have a link to one that will work?
EDIT: -- Ok, I just tried another generic that I have here. It's a 5V 2.1A and the tablet is actually charging... oddly though, it doesn't show the charging icon nor does it say it's charging... but it is.

You need a 15 volts adapter not 5 volts!

The weird thing is, the Surface Pro charger I have is 24... and it charges just as fast as the 5 I used last night. I borrowed an Asus brand charger today and had no problems at all with that.

Display issue issue has me stumped

OK, picked up a tf700t with the dock for next to nothing(30$) It has a slight issue.... the display doesn't work. Here is the issue. The tablet charges, holds a charge and functions fine... when plugged in to a PC. If it is not plugged into a PC, the display is dark. Touch screen works, HDMI works whether the tablet is connected to a PC or not. I am thinking it might be the power port as the Asus charging cable is very loose when plugged in. I have taken the tablet apart and nothing appears out of the ordinary. There is some scorch-like damage to the cable from the port to the mainboard.
I am stumped. I don't think it is the mainboard as the tablet boots just fine. I already have it unlocked, TWRP installed and running KK Nougat v13. Pics to prove my point
Tablet plugged into TV via HDMI, but not plugged into PC
Tablet plugged into PC and TV via HDMI
yes, I have searched and while many have posted the issue, I have not seen an answer to the issue. I am thinking if it isn't the power port, that it be the battery not putting out enough voltage. Any help or ideas would be greatly appreciated. Oh yeah, I have to wiggle the plug in the power port to get the screen to come on. That is what has me thinking that it might be something with the port
One more data point to add. Display works when the tablet is plugged into the wall charger.
Beginning to think that it may be the battery. It may be charging and holding a charge, but it may be discharging at a lower value than what the mainboard wants to see. Would this cause the display to turn off?
