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?
ThePCTech
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.
ThePCTech
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.

As of this morning my TF nor the dock will charge from the charger. I suspect the charger itself is damaged somehow but I cannot find anything physically wrong with it from the outside.
EDIT: Weird, after the 20th time playing with it, taking it apart, reseating the USB cord, etc, it finally started charging again after hours of aggravation. Hopefully it stays that way....
I'm thinking the inner pins somehow lost contact with the interposer. I've also noticed that the adapter gets alarmingly warm when charging. As in it's hotter than the PSU I use for my Alienware m17x R2, which is almost hot enough to give a mild burn.
My charger gets pretty warm as well. I think because its charging the device at such a fast pace.
Takes twice as long to charge my phone than the transformer!

Yeah I'm just hoping this whole thing doesn't keep happening. Had the charger on the dock for a while before I realized it wasn't charging since there's no indicator other than the LED. I'm just glad I got the dern thinking working again. Figures it would get fixed not 5 minutes after I post here and send a ticket in to Asus.
I wonder if cutting a few vents on the charger or at least blowing some air with a fan might help. Perhaps there is a thermal protection shutdown circuit.
there are several threads about this here one;
http://forum.xda-developers.com/showthread.php?t=1042868
i had the same problem, not had it since, something is definitively happening with the charger, changing sockets seemed to help
My charger actually died on me. It doesnt charge at all anymore with the included charger. I can still use the cable to charge off of USB, but that is sloooow. I bought an iPad charger (2 amp) and it charges a bit faster. At least I can still use my tablet until a replacement charger is available.
Just FYI I was told by Asus CS a replacement would not be available for awhile, and they wouldn't RMA the charger by itself.
Sounds like many of the charger problem is the contact between the country plug adapter and the charger itself. First thing I would do if it stopped charging is remove the country plug adapter , clean contacts and reinstall. Sometimes in the process of plugging in or removing the charger, you move contacts enough to either make or break the connection.
Loses charge significantly on standby
I left it on standby last night @ about 70pc. When i turn it on this AM, it is at 20pc Any workarounds?

Standby and off are very different states. In standby, it's STILL RUNNING. If you leave the WiFi on, it's still communicating over the network. Applications are still running in the background.
I did a test recently (right before I got my dock). I left the TF in 'standby' with WiFi on (turned off the sound) and went to sleep. About 9 hours later, the battery was down around 50%.
Next day I did the same, but I turned off WiFi. Battery ended up still being above 90%.
The workaround is turning it off. Disabling WiFi reduces battery consumption in standby, but it does not eliminate it.
And for the 'stopped charging from the AC adapter' issue, it seems that unplugging the adapter from the wall for a while seems to reset the charger.

I feel this is a shortcoming of honeycomb than asus. hopefully this gets fixed in a future update. Havent seen this behavior in any other mobile device.

Which part do you think is a problem with Honeycomb instead of Asus?
The dock issues or the power supply not charging? How can the OS be responsible for either? (save for driver issues with the keyboard, which Asus fixed with an update)
I actually had this happen to me, but reassembling the charger didn't fix it for me. I ended up restoring to fix it. Haven't had any issues since.
I had the same problem. Did as stated above... Left charger unplugged for 20-25 minutes, then gave it a try and now it's back to charging... All good.
Information of PSU model with known fault here:
http://forum.xda-developers.com/showthread.php?t=1081435
Possibly a related issue? My Transformer is now not charging although I believe either my cable is faulty or the connector to the tablet itself. I don't have my official Asus charger with me today so I plugged it into another USB power charger and I get nothing. When I plug the cable into my computer the Transformer does show up as a device in Windows however there is still no charging.
So I left my tab on the multimedia charging dock overnight only to wake up this morning to the battery still at 4%! I did not turn it off though. Has this happened to anyone? The tablet is 10 days old.

The fact that it didn't completely drain to 0% makes me think that perhaps you didn't use the Samsung supplied wall plug?
The tab does not need to be powered off to charge, however you need to use a 5v 2a wall plug to charge the tablet. It sounds like your tablet was getting a small amount of juice that kept it from going to zero so perhaps the wall unit you used was 1a or .7a?
If not, I'm not sure what the problem was, but I never power my tab off and it has no problem charging with the supplied equipment.
I was using the Samsung wall adapter, but there is a USB cable extender (cable is too short) in between the adapter and the tab USB cable. I will try again later without the extender and see what happens...
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,
i've got a big problem...
I've bougt a used EEE Pad with Prime 1.7 and it doesn't charge.
I tried USB-PC, the original AC Adapter and one from artwizz.
The Pad has 13% power, wenn i put it off and plug it in it reboots like it's charging but it says: 13% remaining please plug in...
What should i do?
Thanks in advance!
Try leaving it charging for a while with screen off. If when you turn it on after several hours the battery has charged a little, then the charger is only delivering 5V and not the 15v needed for fast charging. The 15V is triggered by an gnd connection on pin 7 of the USB connector from the TF. Are you using any kind of USB extension? Std USB 2.0 extensions will not work. If all else fails get a Dynex DX-UA universal camera charger ( most electronics big box stores) and set output for 11-12 V.
I had the same issue couple of weeks ago (I posted here as well) and even got an RMA from Asus to send it in; but I didn't have to. In my case the battery was empty and when I plug in the adapter it would work but would not charge - the battery had an exclamation point on it and would not change to the "lightning bolt" indicating that it is charging. Since it works from adapter, that most likely means that adapter is ok. I also have a dock and when I plugged the adapter into the dock, the dock was charging so I knew that adapter is good. However, TF was not charging regardless if it was docked or not so I thought my battery died. The day before I sent it in for RMA I had it completely off and plugged in for a day or so. After that when I turned it on the battery showed full charge and it has been charging fine since then with no issues. So as Rumbleweed suggested below, as long as your adapter is good, turn your TF off completely and leave it plugged in overnight or longer. See what happens.
Good luck.
Will the Transformer show charging with 12V and 1500 Ampere?
At the moment it charges with a 5V 1 Ampere wenn its off.
The original adapter seems to be defect, but it works two days ago...
I've orderd a cheap 5V 2A to charge it over night. I found on amazon an adapter with 12V and 1,5 Ampere. Will it charge with it wenn i use it?
The original adapter costs 39€ and with a RMA i've to send the whole tab.
edit: An adapter with 12V and 1,5 Ampere should be working?
Mine has stopped charging today while the TF in on. It's only charging when the TF is off.
It will be soon three months I have it and it's the first time it does that.
When I touch the adapter, it's hot as it used to be before today.
I've tried to power it off and on many times.
hi all
i change my charger today ... same stuff, seems recurent problem.
Had my first issue with charging. It hasn't been on the charger for 24hrs now, finally got down to 28% and decided to charge it up while I take a nap. Went to pull it off the charger and it was down to 17%.
I tried unplugging and plugging in, tried a different wall socket, same issue. Tried my PC, it would connect so I could see the tf101 storage but would not charge, not sure if its supposed to. I tried different 5v wall chargers hoping I would see some kind of a reaction, nothing. I went back to the stock wall charger, plugged everything in and it started to work. I know people have suggested freezing the wall charger, not sure if that's the issue or not since it started to charge. It almost sounds like maybe a sync cable issue bad pin connection. Your thoughts?

the common 5v usb wall charger will not charge the asus transformer, needs 11v irc
some earlier transformers had problems with their chargers, I don't know if this still happens. I had to return my first transformer because the charger packed up, That was in August and I have had no problems since.
if it happens again you could try taking off and reseating the bit with the country specific pins, as they have been known to come lose.
two posibilities
the wallwart uses a snap in male country adapter. sometimes the connection is intermittent and it will not charge. plugging in and out moves the contacts and makes it work.
other possibility the charger senses a gnd on pin7 of the USB connector to tell it to output 15v on the positive pin. if it does not see the gnd, it delivers 5v which will charge the TF in about a day if turned off.

I'll check to see if its snapped in properly.
Mine stopped charging and seemed to trip the temp safety sensor inside the charger. I popped it into a freezer bag and stuck it in the freezer for about a half an hour. Once removed from the freezer and bag, it started working again. I haven't had issues since.

How come sometimes I am using my transformer tf101 while it's being charged, instead of charging the battery gets used up???
On the TF try blowing hard on the connection port. Dust has been known to stop charging.

What you are actually doing is using your TF while it is plugged in. It is not charging. The battery discharges because it is not charging.
Could be one of several reasons Most likely three are ( in no particular order)
1. Over temp protection in wall wart has tripped ( unplug and stick in freezer for 20 mins
2. The male country adapter ( power prongs) is not making a good connection where it connects to the charger. Wiggle or unsnap and reinstall
3. Pin 7 on USB is not seeing a GND signal from TF causing powersupply to supply %v only instead of 15V. Clean /inspect connector on TF and corresponding plug. This will also occur if you use a USB extension cable that does not have all the connections for USB 3.0
