[Q] Defect Battery? - Eee Pad Transformer Q&A, Help & Troubleshooting

I am not sure what the problem is, so maybe someone can help me.
I have a tf101 whit docking not rooted or anything.
The battery is drained 1% I can start the tabled and it shuts down, exactly what you would expec. When i plug in the adapter directly in the docking or tablet alone. it does not say charching. When i leave the charger in the tablet it is actualy charching(over night it is 30%), but it is not saying that it is charging. When the battry is 30% and i leave the charger in and start up the tablet the battery drains to zero.
I have tried multiple cables and chargers and all simulair.
Anyone?

I just found out that it is charching whit the original charger again. Maybe the charger has been the issue over all.
For now the tablet is charging again and problem looks OK again I still think it is a combo of battey getting bad and bad charger.

[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] TF101G - Charging issues

Hi all,
Sorry in advance if I'm asking for something that has been answered before.
I have seen lots of threads that talked about the Asus Transformer tf101 and tf101G that doesn't charge correctly.
My TF101G stopped charging after it was fully drained after the kids played some games on it. When I plugged it in to charge the TF screen came on with a big battery indicator which showed a empty battery with red at the bottom. Then it just goes off. When trying to switch on again it just briefly flashes this battery and goes off again.
I left the TF to "charge" overnight and this morning after about 6 hours of charging it had +-14% battery life.
So it appears that the charger still trickle charges the TF when it completely off, but doesn't want to charge when it powered on.
Also, the TF recognizes the cable when it gets plugged in. If off and with some power in the battery the TF starts to boot up, but no charge indicator is showed when booted and battery drains as per normal.
Could it be that this is a software issue? I would guess not, but then again I ask myself if the charger or USB cable was broken then it wouldn't trickle charge. right?
Anyone came across this yet?
I know that some people suggested the freezer trick, but I don't want to do that before I checked on this with the community members here.
Many thanks in advance for your assistance and sorry again if I missed a similar thread.

It could. The charger cable got 2 red wires thats connected to the same point on the TF.
One of the wires is your normal +5v USB power, while the other is connected to a USB3 pin to tell the charger to spit out 15V instead of 5V.
If that particular cable is broken, the charger will only send 5V.
The odds that that small wire is broken though, is... well, very slim.

Why did it discharge, and why won't it charge anymore?

Two days ago, I turned my Infinity off and docked it. Both batteries were fully charged. A few hours ago I picked it up again, and the tablet wouldn't turn on.
I plugged it into the wall outlet. It started charging and I was able to turn on the device. It had 0% charge, and the batteries on the dock were also dead. What I don't understand is: how can the Infinity and the dock discharge completely in that time even though it was supposed to be off?
I left it plugged in so that I could use it while it charges. After some time, it asked me to connect the charger and then turned itself off due to almost dead batteries. Cable was still plugged in, though the charging light was off.
Tried connecting the cable to the dock, no light. Tried connecting the cable to my computer, it didn't work. So, the cable must be faulty, right? I can still turn the Infinity on, it'll boot normally and turn itself off after it's reached the lock screen. There's a red exclamation mark on the battery icon that wasn't there in the first time I turned it on, does it mean anything serious?
I had it drain to zero once overnight. Wasn't completely charged but it was strange... hasn't happened since in fact it generally has very good battery life.
I would definitely try a new cable and or charger.
Yeah, I've asked the store for a new cable. They'll have to mail it to me, so my tablet will stay dead for a few days. Now I know why propietary connectors suck.
Anyway, it seems I'm not the only one that had problems with the charger. Many people have reported overheating, but that never happened to me. The adapter that came with my Infinity seems to be a newer model; the plugs can't be folded or detached.
Charger: I had that happened several times to the SL101. Turned out I had something else plugged into the USB and the adapter was overloaded and tripped. Unplugged for a little while for it to cool down and reset itself.
What do you mean you had something else plugged into the USB?
Anyway, I've left my adapter alone for quite some time. I'll go see if it works as soon as I get home.

I was charging a small 700 mAh battery through the USB. That was enough to trip the AC adapter.

Help - Dock not charging

Hello i have a problem with the tablet dock
The tablet was just stored for a long time and i got a new charger because i lost the old one, the tablet works fine but the dock stays at 0% no matter what
i flipped the switch inside the dock like once or twice a day over a week but its still at 0%
I have switched the battery from the tablet wich was at 100% to the dock and the tablet got charged like no problem but the dock it still not charging, right now its at around 80% it got discharged a little over some weeks .
The keyboard works with no problem its just not getting charge or charging the tablet when docked but if i connect the charger to the keyboard while docked it charges the tablet
I hope someone can help me
Sounds like the charging circuit is fried in the dock if the battery charges fine in the tablet

is there any way to test it that you know?
Buy a new charging board and replace it
Other than asking someone with a lot of micro-electronics knowledge to test it, that's the only thing I can think of
They are so cheap now though, it would be easier to just buy another one, you can get both tablet and dock on ebay for £99, or the dock for around £40
Usually when they are stored for a long time, the batteries drain and once they hit 0%, they won't charge again, but if you say that battery still works fine in the tablet half, and the dock can still charge the tablet, then it sounds like it's the actual dock charging circuit at fault, can't think of anything else other than connections being loose between the battery and the dock
The dock battery not working properly
Hi, i have Transformer TF101 (KTU87Q KaTKiss-4.4.4_036) after some time the battery in my dock stops working (icon dock battery display still 0% and red exclamation mark)and while charging the battery dock is still flashing red light. I replaced the battery for genuine type, battery can be charged (green light while full charging - OK) BUT when I turn on the tablet, then some time icon shows 0% and red exclamation mark after that for example 96%, when the tablet battery is discharged, transfomer shuts down and the icon dock battery still display example 94% What is wrong?
I made a battery calibration but nothing has changed.
Why new replaced genuine dock battery not working?
Thank you
Meldo

I recently had a dock that had the same problem. Everything worked fine except that it would not charge a known working battery. Make sure that you have the switch in the correct position. From what I recall, the switch has markings on it that show in one position "0" and the other "1", similar to a power source switch on a desktop computer. You want it in the "1" position.
Also, does the battery indicator light come on when the battery is less than 90% and you are connected to the charger? Are you using a OEM ASUS TF-101 cable and power adapter?
It may be that the dock has a hardware problem in which case the only thing that will fix it is a new board. Not really worth fixing as this is now 4+ years old and there are many devices that can be purchased brand new for the price of fixing the dock which are vastly superior to the TF101.

Battery dock replaced but still no charging!

I've successfully replaced the battery of the dock with a new one. It was showing some charge 36% instead of 0% and no more tablet draining, but it never charged! So now it's at 9%, red dot blinking, and I don't know how to fix it! Charging sign appears when plugged in and tablet charges trough the dock.
I've tried the cold boot and the trickle charge but I didn't see changes, maybe I've done something wrong?
What more can I do to make it charge again?
I thought it was the charger or the cable but for what I see the 40-pin connector has actually only the 4 pins (the usb signal) so I don't think I need another cable.

I don't believe it is a software issue. It might be a contact issue caused by yourself I think.
Firstly disconnect your tablet from the dock. Connect it with the charger and check if it is going to be charged. If so, your both charger and cable are OK.
Secondly check whether all contacts between the battery and the dock are closed correctly or not. Please follow backwards the sequence you used to taking out the old battery by yourself.
try and charge it with the official charging brick, or at least something that can put out 15V at 1.5A i had the same problem when using my tablet after a long time and only my tablet would get charged not the dock
Yes I'm charging it with the official charger, maybe it got some problems
I don't have a tester at the moment but I got a doubt. Is it possibile that the cable has 2 charging lines one for the tablet and one for the dock? Because I want to buy another charger but maybe it could be not compatible for charging also the dock.
I opened it again last weekend and there was nothing unplugged, everything was good.
