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.
I think this is getting quite critical for me, and I have seen a few others having the same issue. I kept my dock charged all weekend(solid green light), and last night took it off charge closed lid and put it in my bag. Today, I opened the TF and installed the awesome Battery widget from the Apps section, and it says my dock is at 3%, and my TF at 97%. So in a matter of 14 hours, the dock has been drained with the TF being idle and screen off.
Link to the battery widget?

Was the tablet on the dock when it was charging?
yes. the tablet charged first and then the dock charged.

FYI: In a recent "test" I did with 3.1 the dock battery lasted 30 hours from green light to flashing red (orange) light (I didn't have the great battery widget at that time. I just installed it!!!). This is with 4-5 hours of moderate use (navigation, email, some youtube), 10 hours of standby with wifi off and the rest (15 hours) of standby with wifi on.
This means around 3%/hour battery drain while on standby.
Joël.
Which is unacceptablet. the iPad, and the Nook Color lasts easily a week in standby.
Hey all, first off, thanks for the link-age to the battery widget. I can finally see what's going on with my dock battery status....and that status is NOT good
I posted in another thread that I had charged my dock as soon as I got it (before connecting to the tablet) for 18+ hours, and I never saw a green light. After that, I connected it to my tablet running Primordial 3.1, it offered to update the dock FW to 0209, and I allowed it to. It said update successful, and Settings confirms the dock is at v0209.
Problem is, now that I can see my dock battery status with that widget, it shows only 37%. My tablet is at 100%, so I figured the dock should then take the charge from the official ASUS mains charger, but this doesn't appear to be happening. As soon as I plug in the charger, the widget shows "Dock Status: Charging", then after 1-2 secs, changes back to "Not Charging".
The dock light is solid orange while I have it "charging"/plugged in, and I have NEVER seen it turn green. When I disconnect the charger, the orange light on the dock flashes infrequently, telling me that it has less that 95% charge. I am not sure if there is something faulty with my actual dock, but people reported that the v0209 FW fixed most issues. I just wish I could get both battery statuses to 100%!!
I wish ASUS did a better job on this dock. I know that it is a groundbreaking product here, so bugs are expected, but since it is hardware and I only have 14 days to return it to the store I bought it from, it would be good to know what the beep is going on...
Any thoughts, suggestions, comments would be appreciated!
Thanks in advance...
We may still be waiting on the battery saving fix from Asus. They've mentioned the dock is draining too quickly (especially in standby) - haven't seen an improvement even with 0209 upgrade so hopefully we're still outstanding!
The "mobile dock battery saving mode" under settings -> screen seems to help a litle. Lost ~30% overnight on dock charge, and dock has just hit 3% after a good 4 hours use so far today.

Thanks for that Highland3r...but may I ask, have you guys ever seen your TF dock hit a 100% charge? I'm still puzzled as to why mine is stuck at 37% and the battery widget shows that the dock is not charging.
Also, what is the supposed process when the dock and tablet are joined, but OFF of the charger? I would assume that the dock charges the tablet until it runs out of juice, then the tablet battery would decrease?
Funny because when I have none connected to the charger, but combined, my battery icon does not show that the tablet is charging. Maybe in this case, the dock battery + tablet battery enter some sort of parallel mode, which combines the draw from both (as one big battery?)...No idea here, but I still think something is wrong if my dock won't show past 37% and others have (possibly) seen their dock charge to 100%.

Sorry I can't give you any useful comments other that I have a similar problem. After one successful initial charge (successful meaning the light turned green), the dock will not completely charge anymore. I had the dock by itself on the charger for 11 hours and still had the orange led. Unplugged the charger, docked the tablet and immediately got the flashing orange.

Yup, dock hits 100% charge.
When combined but off AC, tablet remains at 100% charge until dock hits ~3% then the tablet battery drops.
Looks like, once the tablet hits 100% it no longer shows the charging status, just shows as full until it drops down to ~95%.
When charging, the tablet charges to ~100% first, then the dock charges up.
Have you tried charging the dock alone (i.e dock not connected to dock) overnight and see what the charge shows the next morning?
Here's my experience today with the dock... Took my dock and tablet off charge at 7:00am this morning. Started using it at a Google AdWords seminar at 9:00am for taking notes, email, doing Google AdWords stuff, etc. It's now 2:30pm, and the dock is at 27% remining. The tablet is at 100% remaining. So, that's 5.5 hours of solid use, and the dock still has over 25% remaining. If it keeps up, I should get to just about the end of the seminar at around 4:00pm before I start using the tablet's battery.
This seems pretty good to me.

Yes, I did in fact charge it alone for 18+ hours as soon as I got it, before ever connecting it to the tablet.
Right now I'm running more tests, and as both devices are coupled, OFF of the mains charger, my tablet is NOT receiving a charge at all. I ran some battery-intensive tasks to get the power level to drop below 90%, but the dock still never seems to charge the tablet (I don't see the battery icon change, nor do any other indicators show that the tablet is getting a charge when docked). Still says the dock is at 37% power, which I've never seen change after getting the Battery Widget, so I'm thinking something is wrong with my dock.
BTW, did you guys update the dock to v0209 while on Primordial 3.1? This is what I did, and while I suspect the FW was not modified by Roach, it should have flashed fine (which it did say after I performed the dock FW update). Although, as I did the update, it stayed at 0% for a while, then immediately said "Update Successful". A bit odd, but it still shows v0209 in the System Settings, and appears to work fine. It's just this battery madness!!
Will give it another day or two, but then might return it to the store before my 2 weeks are up.
Thanks again for the feedback all...really helps to try and figure out what's going on...
I've run some test, and to sum up, with the tablet docked with the keyboard, I've lost 16% battery in one night with the tablet TURN OFF ! (and not in stand by mode) !
Is Asus aware of this problem ? Is a fix on the way ?
Thanks, and sorry for my english !
_Believe_ my dock update came from a Modaco release - HR4 or 5 maybe.
Just to clarify - the dock constantly shows 37%? Doesn't drop lower and never increases? Seems a little wierd - would expect some battery drain of the dock due to the "other" issues.
You maybe best off trying an RMA on the dock, or contacting Asus and see if they can suggest anything.
One other thing to try (just to rule things out) is to run the following command via terminal emulator on your tablet (you can probably use ADB via a PC too if you wanted)
If you can post (or PM) the output - these two entries look to contain relevant information on Battery Status etc.
Try pulling the dock whilst running the logcat (you should see new entries on keyboard remove and keyboard dock, try the same with charged vs non charged too)
Code:
logcat BatteryService:D DockManagerService:D *:S
Lsst night, another test on the drain rate of the dock. At 11:45 PM, dock was at 61% and tablet was 100%. Today at 6:45 AM, the dock was at 27%, tablet was still full. So in 7 hrs, it drained 34% or 5% an hour on idle.
Is that consistent with what others are seeing?

Yup pretty much seeing the same. 30% drop overnight from a full charge
Hey Highland3r,
Thanks again for your help with this. I saw your post about the logcat BatteryService filter elsewhere, and I have been running it since last night (I wanted to post it before bed, but fell asleep on the couch!).
Anyways, it is attached as a .txt file so as not to clog up this thread. I did not clean it, so it has a fair amount of lines, but you will notice that my dock did drop down to 36%! Unfortunately, the tablet also goes down to 90%, so this is why I fear there is something wrong with my dock, as it should be keeping the tablet at 100% until the dock reaches 3% (or 0%).
By looking at the log and analyzing the STATUS parameter, it seems to me that:
Status = 2 (means charging)
Status = 4 (means not charging)
Status = 5 (means full batt?)
My "dock_status" appears to reflect the same, but you will notice "dock_status = 1", which shows a 0% level (this is when I was plugging, unplugging the dock from the tablet).
Anyways, I know it's tough to figure out what's going on, especially since your docks seem to be working quite nicely. I can't imagine that it would take forever to charge the dock, but the funny thing is that it finally dropped 1%, but is still NOT charging my tablet. I also do not see the tablet in charging state when both are connected, but not being charged from the mains.
Thanks again for your help, it's very much appreciated. I think for now, I will leave them both connected to the mains charger, and see how long it takes the dock to increase past a 36% charge. Otherwise, it's going back to the store I got it from 3 days ago for a new one.
A question for those of you who have docks that do charge correctly.
How warm does the wall adapter get when the dock by itself is charging?
I know when I charge my tablet by itself it gets very warm, almost too hot to hold. When I charge my dock by itself the wall adapter is barely warm. Maybe this temperature difference is related to why my dock will not get a full charge. Something is telling the wall adapter or preventing the wall adapter from outputting the correct power.
Hi,
Has anyone had this happen or know how to fix this? Last night, my tablet was docked. the battery widget I installed said tablet was full, but dock was at aabout 32%. I plugged the "netbook" in to get charged. This morning, I woke up. There was no battery light on the dock anymore, and it said it was only at 76% and not charging.
I have tried unplugging from the dock, and changing to a different outlet. However, it doesn't seem to work?
Thanks
Try unplugging the charger from the wall and let it sit 20min then try again dock only. if the charger gets too hot it shuts down. also try moving charging cables.
PS I would not leave charger charging overight.
I think the charging cable is fine. Because if I plug it into my tablet, it started charging it... but if I move to the dock.... I get nothing
Try letting it sit plugged into dock only for a while. Others have reported that if you draw the dock battery down to zero, it doesn't charge correctly. Some times starts and sometimes will not. LiPos do not like to go to zero.
I haven't hit zero yet. widget is reporting 52%. Ok, let me try.
still no charge for the keyboard battery. Although, if I dock, it will still charge my tablet
That's happening to my dock too. It doesn't get charged at all anymore (I have the TF101 since 1 week). It has 27% left and I don't dare to use it at all before Asus finds a solution to this problem.
The tablet is charging perfecly and fast.
I have to dock the tablet before my keyboard dock will start charging. I can undock once it starts charging and it will continue to charge, just doesn't start until tablet is connected. This just started happening after using/charging the dock perfectly fine for the first four days I had it.
At least I can still charge it, probably just keep it for a bit until some info on fixes comes out.
I reached ASUS tech support. He gave me an RMA number to get the dock sent to them to get looked at.
