[Q] [HELP] Tablet/Dock not charging - Eee Pad Transformer Q&A, Help & Troubleshooting

Seems I probably have an issue with the charging cable for the tablet. Cannot get the dock or tablet to show any signs of charging. Unfortunately, none of the stores in my area report having a replacement cable.
Does anyone know another ASUS or non-ASUS device that uses the same end? If I can't find something else then no tablet until I can get a new one off the net which really sucks.

I was able to get the wall charger to at least light up the dock LED and act like it is charging. However, no matter what I do can't get the tablet to turn on. Doesn't matter if it is docked and charging that way or charging straight.
Any suggestions?

[Q] TF101 NOT charging

Is anyone else having an issue with charging? it worked fine for a week or more. now when i plug it in, to any outlet, it wont charge at all.. they are considering RMAing the entire unit, and im going to be torked off if i have to wait weeks to get another. argh.
just curious if anyone else is having charging issues.
thanks
My unit doesn't charge if the battery is above 90%. I see no problems there, what % is your battery at? That is expected behaviour to an extent to prevent overcharging of the battery.
Sent from my Transformer TF101 using XDA Premium App
Mine did that once and I just left it alone for awhile and it started to work again on its own.
i only noticed it because its asking me to connect to charger now.
so its at 11% right now.
Tech wanted me to trickle charge to see if i get anything out of it. Its not working.
Is there any lights on the adapter? i cant remember? but i think the unit may be bad.
SOOOOO pissed, now i have to wait weeks for a replacement to show up.
Has anyone else had a unit they have had to RMA??? is so, did they send a brand new one, sealed in box? if so, i have an extra here, ill just use it and sell the RMA one when it comes in.
thanks
EDIT: i had it trickle charging in the off position. just turned it back on. then plugged it in to wall. seems to be charging now.. WTH. wonder if its something with the dock?
Thanks
Hi
Nice to have found your thread on this - mine was doing the same thing after I had if docked. Connected it to my PC and synced and then put it back in the charger and everything is fine.
Weird.
Since you guys seem new to this forum, I suggest you read the stickies. The "Ultimate Transformer Information Thread" mentions some specific adapter issues you should be aware of.

TF101 not charging after run flat issue - SOLVED
Hello
I also had this problem. The tablet drained the docking station dry, and then neither device would charge from the adapter.
I solved the problem as follows:
1) Remove table from docking station.
2) Turn tablet off completely.
3) Plug tablet only into the charger, at this point the tablet turned on, and began charging.
4) Allow the tablet to charge completely!
5) Reconnect tablet to docking station, and plug docking station into charger.
Voila, all charged Hope it works for others who have this issue!
Mine also had charging problems. When I charged it, it never reached 100%. I took it to the Asus repair center, and they called me today and said they got it to reach 100%. Also, above 90% it reports the battery status as full.
I also to them about the battery drain problem, and gave them my tablet with the dual battery widget installed. Told them to charge both the tablet and keyboard to full, dock the tablet, power off, and wait until morning to see the results.
I'll find out what happens tomorrow when I go see them in the morning.
TF101 not charging today...
It happened already once some time ago, but leaving the power adapter disconnected from the wall plug for 10min solved the problem.
Now it's happening again... and previous workaround is not working.
Tablet is TF101, no docking keyboard, last version of ICS installed.
I've checked the various threads for suggestions: of course I tried the various reboot options; the only thing I'm missing is the refrigerator, but the power adapter is cold (tablet is not charging since 2d, and battery is still alive...).
I've not checked the cable, but have cleaned with air the connectors (just to avoid dust inside).
Any suggestion is welcome.
Thanks
I have had my charger stop working twice in the past 6 months. Both times I put the wall adapter in a zip-lock bag and placed in my freezer for 30 minutes. Upon removing I plugged the usb cable back into the adapter and bam, everything was working fine again. From what I remember, there is a temperature sensitive circuit breaker inside the adapter that sometimes gets stuck. Even if the charger is cold or has been left alone it takes the dramatic temperature of the freezer to unsieze it. Good Luck it worked for me, twice.

[Q] Asus TF Keyboard Dock not holding a charge

I'm wondering if anyone has experienced this. So far I've tried charging the dock for 9+ hours and when I unplug it, the LED still starts flashing as soon as I unplug it, indicating less than 10%~ battery left. I don't think this dock ever got a full charge ever.
Am I doing something wrong, or should I RMA the dock?
Bump, see if anyone knows the answer.
Is the charger getting hot when you plug it into the keyboard dock?
No, it doesn't get any hotter, but I know that it's passing power to the tablet, since the cable goes into the Mobile Dock and the Tablet is docked, the tablet gets a charged to 100%, but Mobile Dock doesn't
Remove the tablet part and just charge the dock on its own.
yep. charge them separately. i believe that if they are connected the tablet fills to 100% before the dock even starts to charge ....

Tried it, over 10+ hours, still the LED starts flashing as soon as I unplug it.
I think I may have to RMA

I got same problem too.
but the charger is hot while I charge tablet or dock or both together.
dock is not charge, it always 0%.
sorry for my bad on english
Is the dock FW up to date ?
TBH .. i'd just RMA it, if its under warranty, just get it sent back.
P.S. Download the dual battery widget to see what it displays for the dock power ... but still RMA it.

[Q] Tablet Not Charging After Using Dock? (How does this make sense?)

I've never had any problems with charging before until today I finally found a keyboard dock for my Asus Transformer. I plugged it in and tried to charge it but it was not charging. Then I unplugged the keyboard dock and my tablet itself would not charge. Did docking the tablet cause this problem (maybe the update it installed upon plugging it in) or is it a coicidence that my cable just stopped working. Either way I'm freaking out!
I may have the same issue or a simiar issue before with the charging but later I found out it wont charge when it at a certain percentage. Basicly if the % around 95 then it wont charge but for example you at 70% then it should start charging again. i would say it like a preventative measure to prevent over charging. If that was the case then this should be the reason.
On a side note I recommend dling dual battery widget so you know how much batter your dock have and tablet so you will not be charging it all the time thinking it might be out soon.

[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.

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?
