So my 16gb Asus Transformer has a very strange problem. I have not seen it mentioned anywhere. When I plug my unit into the supplied charger there is NO indication on the device that it is charging. It takes about 10 hours to fully charge.
Here is the really strange part... When I put the device into the keyboard dock, I get a charge symbol on the battery and it says charging. To make things even more strange the cable and wall wart provided with the tablet quick charges the keyboard dock, light is red then turns green when fully charged (no longer then 2 hours so far).
How could the charger charge the dock no problem but not charge the unit itself? My thoughts were that the dock may seat farther into the tablet then the cord does so I took a small file and took off a little of the plastic on the eee pad connector side, that did not help at all. Any ideas?
I have flashed the latest software update, and I have done a "Factory Data Reset" and it will still not "quick charge" from the supplied charger, only from the dock.

I must admit that I expected to see a charging light on the pad itself, I think the hole you mention may be the light sensor.
When I use the official charger, I get a lightning bolt symbol and it charges fairly quickly. When I used my Kindle charger or an HTC one and plugged the USB into them, I had no indication it was charging and it was really REALLY slow...

The ASUS charger is rated @ 15V 1.2A. Most USB chargers are 5V. USB itself is rated @ 5V. So I donno how it can use 15V via USB. I tried several different chargers with much higher amperage but no luck at all. Quite strange I must say.
Let me clarify, The ASUS Eee Pad has no charging lite on the unit itself. The only indication is in the taskbar on Android 3.0.1. The battery will change from a green battery symbol to a green battery symbol with a lightning bolt on it when it is "Quick Charging".
There are two ways that the device charges, the first is a quick charge (with lightning bolt on batt. symbol), the second is a slower trickle charge (no indication). A quick charge should take about 2 - 3 hours to fully charge. The trickle charge will take up to 12hrs. The ONLY two ways to get a "Quick Charge" is 1. To use the provided charger (came with the unit), and 2. Is to put it in the dock. A trickle charge can be done with ANY other USB port (ie. laptop, desktop, iPod AC adapter, ect.).
My ASUS Eee Pad Transformer will ONLY "Quick Charge" with the dock. The cable provided with the unit will NOT "Quick Charge" my device.
Anyone else have this? If so do you have a fix?

FIXED!
Ok, so here is the deal...
I ordered a 32gb version and I'm givving the 16 version to my wife. I tried the new plug in the old tablet and the same thing happened. So I thought it MUST be the tablet and NOT the charger as I thought it was.
Looking into the bottom of the tablet I noticed a pin that looked like it was bent. If you look into the socket with the screen facing up. The 4th or 5th pin was bent up and not sitting in the track like it should have been. I compaired this to the new 32gb version. I used a needle to gently move it into place and tried again and it charged as it should with both cables. Newegg offered to replace the unit, but everything else works great on it and, now it chages just fine. I'll just keep it.

If anyone else is having a problem take a look into the socket of the tablet, it could be a quick fix.
i fixed my charging problem by doing a factory reset.........wow...
Same problem
I have the exact same problem, but mine didn't start until I applied an update from asus.
I think I may have *had* the same problem. I returned my transformer to sears after it would not charge. After my return a clearance sticker was placed on it and now after reading this thread I am considering repurchasing the transformer and getting a new adapter. But I am concerned that it may be something wrong with the tablet itself. This thread leads me to conclude it is the former. But what do you think?
I was not able to charge through the adapter - however, when connected through the USB cord my laptop did recognize it. I did not leave it connected for longer than 10minutes -I guess if i left it in for 12hrs plus I would have a conclusive answer - but to late for that now..
I got the tablet today -it had 5% battery and after trying three outlets it shutdown- it would restart and not get past the homescreen (which had the time and stated to connect the charger and the lock) it would then shutdown.
In the 20 minutes I was able to use my transformer it worked great

The "hole" next to the camera is the light sensor.

Your unit is working correctly. There is no charging indicator on the tablet only on the dock. The tablet show charge status via software in the lower right corner of the display or in setup which will show percentage.
When you connect the unit to the dock, the tablet is charged via the batteries in the dock. The goal is to ensure that tablet is as charged as possible so you can undock and go knowing the tablet is charged. The charging from the dock to the tablet will only occur if the tablet is below 97%. The indicator light on the dock only refers to the charge status of the battery on the dock, not the tablet.
Someone referenced the little light on the front next to the camera, that is not a light. It is an ambient light sensor for the tablet.
The colors for the charge light indicator on the dock are documented in the manual. As I remember it they are <10% quickly flashing orange, 10-50% slowly flashing orange, 50-95% orange, 95%+ green.
I am also having charging problems with my Transformer.
Everything seems to work fine when I used the supplied charger and the USB plug, both with dock and with just the transformer itself.
However I'm presently away and only took the USB cable with me. I've plugged the USB cable into my travel multiplug, which has a usb slot as well and I'm getting no charge at all, either on the dock or the transformer itself. Also the battery is showing that it is actually draining, even while connected to the multiplug. I've also tried connecting both the dock and the transformer to my juicepack (rated at 3.7V, 4,800mAh), but no luck with that as well.
Anyone else had these problems?

The Transformer will only charge by USB using the supplied wall adapter. Not sure why that is, but that's been my experience.
my problem too.. I got mine yesterday and updated the software straight away. it charged all night and charging worked on both the pad itself and the keyboard.
today it doeasnt..
the cable and the sockets are fine (my pc sees it and did some file transfers) so hardware seems ok. the charger gets quite hot though. does anybody experience the same? maybe its the charger? I wonder if factory reset would help...

the wall plug that came with the TF is rated for 5V-15V, 2-12A. This is a lot higher than normal USB, which is 5V,1A max. When you plug it into a normal USB jack, you are only in trickle charge mode, and i think it's only with the screen off.
I purchased my transformer this evening, along with the keyboard dock. I took both out of the box and plugged in the transformer to the dock and proceeded along with my business. I plugged it in to charge a bit later, and for some reason when the dock is plugged in now after about 1 minute it stops working(both keyboard and touch pad) and the battery icon on the transformer turns into a ?
Should I return the keyboard dock? Does the battery just need to charge up? I am not quite sure but I was quite dissapointed.
Make sure both are charged and then check for updates under about tablet. The old docking firmware used to stop the dock from responding all the time. The latest dock version should be 0209. If you still can't get it to behave then maybe a duff unit and you need to take it back.
ASUS E PAD Transformer TF101 battery & charging query
I found some people query about TF101 battery & charging , so summary some info to all TF101 owner.
Q.
While charging the tablet and docking with adapter, do both get power together?
A.
The adapter will charge the tablet first and then the dock.
When the docked tablet is unplugged with adapter, the dock will provide the power to maintain the tablet for 100% until the dock hits 3%.
Q.
How could we check the information regarding status of battery in TF101?
A.
Go to Settings>> About Tablet>> Status, then you will see some information regarding the status of battery.
Q.
What is the battery life of Eee-Pad?
A.
9.5 hrs of Tablet only/ 16 hrs of docked tablet.
Moreover, the dock will provide the power to maintain the tablet for 100% until the dock hits 3%.
There are some power will be consumed during the power transportation, so the total amount will be not 16 hrs in this situation.
Q.
Could Eee-Pad transformer be charged via USB with computer?
A.
The voltage which be needed for Eee-Pad is 15V,1.2A.
We strongly recommend customers use official exclusive adapter for charging, because the computer can’t provide enough power to Eee-Pad in normal situation.

Hello,
I need help with a charging dock I purchased ASUS 90-XB3XOKDS00030- Dock for Nexus 7 1st Version
the purpose of this dock was because my kid destroyed the micro-USB connector anyhow I've tried the charging cable that was used
to connect my N7 but when the tablet is on the doc it does not say say the table is charging nor do i see the little lighting bolt inside
the battery indicating that the table is being charged. My table is rooted and is running on paroniod android.
is there any settings i have to press within the tablet to have the N7 recognize its being charged from the Dock?
any feedback would be appreciated.
thanks,
All I can suggest is check the contacts. Make sure it is firmly seated on the pogo pins and that nothing is obstructing the contacts.
2 days 19 hours on battery???? How do you do it??
I'm having exactly the same issue, the dock arrived today and the Nexus which already had a flat battery isn't showing any signs of life. Did it get yours to work? I'm on Stock 4.4.2.
Update - It was charging after all but unlike when charging from the USB socket it doesn't show any charging indicators when it is off and charging from the dock.
I have show mode charging dock for fire HD 8 2017. But it doesn't work after I installed LineageOS. Is there any way to fix it?

You can use a wireless charging coil from AliExpress or eBay.
To install wireless charging receiver coil on your Fire tablet:
1. Remove the back cover on your Fire tablet
2. Find the test point (VCHG for charging input), (GND for ground, can be connected to metal shield)
3. Prepare a hot soldering iron, solder lead, and a wire (Red for positive +) (Black for negative -)
4. Solder the test point VCHG (Red wire) and GND (Black wire)
5. Attach the wireless charging receiver coil to battery or the back cover using double sided tape or glue.
6. Put back the back cover on your Fire tablet
7. Put your Fire tablet into wireless charging transmitter (Use input voltage 5v)
Or, you want to fix the show mode charging dock by going back to stock ROM (Fire OS).
