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;

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.

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:

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.
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 - 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.
