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.
Just received my 32gb TF and dock yesterday . I put the TF into the dock with the power cord attached to the dock . It said the transformer was charging so i closed the lid. Today i took both with me out on the go and the TF was full battery so i figured it charged both over night , then i noticed the battery % going down even tho it was plugged into dock ? I thought the tablet used the dock battery then moved on to its internal battery? Then i checked the settings and noticed it says its not charging (from the dock battery, Not plugged in). I have both on charge right now but i dont think my dock is holding a charge . I have both together and the TF is at 100% and the dock got a solid orange indicator. But as soon as i pull the cord out the indicator shuts off ( I don't know if thats supposed to happen) is my dock faulty?
Anyone?? needs to know so if its broke i can rma it
That sounds similar to how my dock/tablet behaves. I think if let's the tablet drop a bit before transferring power to charge the tablet. This depletes the dock below 95% so when you charge the dock you get the orange indicator. The only time this indicator is lit is when the charger is attached and powered.
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.
Hi - had the transformer since the May launch - pretty happy with things. However in the last couple of days, I have noticed something seems to be wrong with the keyboard dock. It no longer seems to hold any charge. Used to be could charge from empty (blinking orange) to full (green) in a few hours or so. Now I charge overnight and it is still orange. Irrespective of anything, when I have the dock on the move - if I plug in the tablet - the tablet still drains (no lightning bolt to indicate it is charging from the dock as previously the case).
Has anyone else seen this problem? Is there a software fix or do I have to return the dock?
What happens with the tablet connected to the AC adapter alone? Does it charge?
I think the dock uses the 15V circuit on the charger and the tablet uses the 5V circuit.
Have you left the AC adapter plugged into a socket for a long time? Unplug it for about half an hour, then plug it back and test.
I recently had this issue too. The dock worked fine and held a charge. Then one day it was at 0% charge, and I plugged it in but it kept blinking orange, even when I charged it over night.
This is a known, but rare, issue with the docks. If you let the keyboard dock drain to 0% and keep it like that for a few days, for some reason it "locks" into always staying at 0%. The battery can never charge again.
The way to confirm this is to download the Dual Battery Widget from the marketplace. It is supposed to show one battery for the Tablet, and a second battery for the Dock. If you have the dock plugged in, and the tablet connected to the dock, and the Dock Battery Widget part says "N/A", then you have the problem I had.
I exchanged my dock at the store. My bad dock was a B50 revision. My new dock is a B60 revision and does not have the Battery Drain issue that people have been discussing (it passes the Test the ASUS representative posted).
I am hoping that this new dock will not have the "falls to 0% and can never recharge" issue my first dock had.
Long story short, I would recommend that you exchange or RMA your dock. The battery in it is bad.
Hello,
Just got my TF along with a dock and it come with completely depleted battery (0%) so I put TF in a dock and connected dock to a charger. TF boots fine but does not show as charging while inside the dock. Is it expected?

The dock will charge the tab first. I'd suggest getting one of the dual battery monitors from the Market. That way you can monitor both easily.
Try this one. I use it and it works fine..
my B80 dock charges to 25% before the tf starts to charge, at 25% the tf charges to 100 then the dock charges to 100 from there.
