stop charging? - Eee Pad Transformer General

Is there any way to stop the dock from charging the tablet on demand or at a pre-set level? I would like to be able to do that because the the last 2-3% of charging the tablet appears to consume more dock charge for a single percent. Up until lke 98% of charge the dock to tablet transfer is 1% for 1%.

If you do not have the dock battery drain issue (the dock battery drain only affects docks made before August 2011) once you get above 95%, undock and re-dock. The dock only initiates a charge on the tablet if the tablet is below 95%.

Tablet doesn't charge if dock is fully charged?

With my dock fully charged and showing green, my tablet was at 97% and I kept it plugged in overnight. This morning, the tablet is still showing 97% so I'm left to wonder if the dock is fully charged, then the tablet won't charge?
Anyone else notice this?
I read in this forum that the TF battery charge of 97% is a magic number which stops re-charging. If you dropped to say 90% the TF would start charging again to 100%. This was implemented as a way to lengthen the life of the battery caused by continuous mini-charges of the last 3%. So I expect that if your dock was still plugged in it is fully charged.
Yeah the tablet is effectively seeing the the power connection as being on mains when connected to the keyboard.

Battery draining on the dock

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.

Dock cannot hold charge

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.

[Q] B60 dock charge level n/a

I've searched the forums and found threads dealing with the dock and charging problems, but they all seem to pertain to B50 models on 3.1. I have a B60 dock on 3.2, everything stock. I have the dual battery widget installed and very rarely i remove my B50 pad from the dock. Lately however I've been noticing that the Dual Battery Widget displays my dock's charge level as "n/a". It shows a lightning symbol when plugging the charger in though.
Last night i had the same problem but kept undocking and redocking/unplugging and replugging the charger in different combinations to try and get the dock's battery charge to show, and eventually it showed up. It's happened today again and no matter what I do I can't get the charge to show again.
The charger itself is warm but not as warm as it usually is. I'm suspecting it's charging the pad through the dock rather than charging the dock since the dock "doesn't have" a charge it can read. Is this the notorious charging bug that people have been experiencing? I thought they fxed it in the newer revision docks (B60 and on)? I'd also like to add the fact that my dock has never gone below 3% as it shuts down at 3% charge.
Any ideas? Is there something wrong with the widget? The dock is fully functioning otherwise as I am typing this post with it.
Thanks
Edit: A screenshot from the Dual Battery Widget: http://db.tt/KN7sY8G
Edit 2: I managed to get the charge level to display by disconnecting the charger, undocking the pad, opening the Dual Battery Widget window and docking while having the window open. The dock is showing 63% charge so it isn't at 0% and i've only tried charging it for the past 15 mins since last night. I'm not sure why Dual Battery Widget is showing a battery drain of that much since clearly my dock has ~63% since last night and even the pad wasnt discharged past 97%.
Any ideas?

[Q] 'Reset' wireless charging via software - possible?

I have a simple Qi power mat that I use for charging my Nexus 4 overnight. It works quite well - a little too well in fact as it charges to full with about 6 hours left of the night. It then "disconnects" from the wireless charger and begins to discharge as if it were just sitting not on a charger.
If my backup is running or some other background tasks occur I end up with only 80% battery left in the morning which is annoying.
The way to restart charging is to remove it from the charger and place it down again - not something I can do while I am sleeping.
I was wondering if there would be a software way of 'resetting' the wireless charging so I could use something like tasker to fool the charger into thinking it had just been placed down again when, for example, the charge drops below 95%?
Would this be better in the Accessories or Developers forum?
