tf201 just update to .13 and now I am not seeing that the key board is transfering power to the tablet. prior to the update this morning I did not have this issue. anyone else have this issue?

I am obligated to ask you this question...
Are you absolutely certain that your keyboard dock has a significant amount of battery, thus enough to charge or "transfer" its power to your TFP?
Mine is not having this issue, nor has it ever.
Always witnessing the arrow symbols indicating transfer.
Sent from the last remaining Prime; Leader of the Autopads.
It had 55% at the tim. About 10 minuteslater it started the transfer.

im confused. how is this not normal? After the tablet drops below 70%, the dock charges it up to (nearly) 95ish %. Then it drains again, and the dock charges it again...?
Are you getting something different or weird?
The power transfer behaivior on my prime TF201 changed when I went from HC to ICS .13. From what I can tell currently the dock supplies all the power and will drain down to 1% prior to having the main battery in the tablet drop below 92%. Prior to the update they would both drain down at the same time with the dock running ~10% lower than the tablet.
This might be tablet version specific as the B1 serial number tbalet that I had prior to it bricking with the ICS update would drain the tablet first then the dock. I exchanged my tablet and now have a C1 series serial number. I dont know if this helps

That's strange behavior. From what I know, what I have described above is what is "normal". Maybe you need to try a new dock?

I think you didn't know how your tablet worked in the first place. This is the way my tablet has worked from day 1 with HC and with ICS. The tablet gets down to around 70% and the keyboard dock recharges it. In fact there are 5 or 6 threads already out on this forum about this topic. If your tablet is working as described here now, then your tablet and dock are working as intended.

Hadn't used my dock for a couple of days and plugged in my Prime tonight to see how the dock held its charge. I was impressed to see the dock at 98%, which is right where I had left it. That's about perfect.
Just thought I'd make note of a significant positive.

Yes, that's something that ASUS needs to resolve. I get about 1.5%/hour usage when the Prime is docked and closed (and thus on standby), vs. about .25%/hour on standby for the tablet by itself.
That's better than what I get with my original Transformer when it's docked, which is closer to 2.5%/hour usage. But, it would be great if ASUS can figure out a way for the dock to not stop the tablet from entering deep sleep.

I don't see it as that much of a problem. If there's truly something about the dock that makes deep sleep on the tablet impossible (I have no idea if there is or not, and it really does remain to be seen), it's not an unreasonable solution to simply store them separately. Even carrying them separately isn't a problem, really.
I do hope that ASUS can enable deep sleep when docked, but if they can't it doesn't really reduce the usefulness of the dock for me. In fact, I use my tablet by itself the majority of the time in any case and thus tend to keep the two separate.
The fact that the dock maintains its charge when undocked is far more important to me, and it does that quite well.
Just a guess but I would assume it doesn't enter deep sleep because it will turn on the screen when you open it. If it is docked and you close it, the screen shuts off but it still needs to monitor the dock to see if you open it again. It would be nice to have an option to have it conserve power (as if it isn't docked) and you have to manually turn the screen on again.

I'm not saying it's the end of the world, but one of the attractions of the dock is to make a clamshell shape that will protect the tablet and keys during transport. sucks if it will drain the battery whenever you want to take it somewhere.
Mine does go into deep sleep, make sure in asus customized setting you put it in battery facet dock mode, then the keyboard doesn't wake the tab.

I didn't know that. Very helpful, I'll check that
I have something setup wrong because my tablet sucks my dock dry in about 3 hours in use - it just never stops pulling the charge from the dock. I only let them sleep together once and it was a disaster ......dock was drained, tablets had rebooted I suppose because it was in some sort of different "mode", it still had life, but it was alien like life!

My wifi is set to never.
I last charged my tab on thursday night, its between mostly idle since then(like 3 hours total use since then) still have 77% on tab and 37% dock.

I'd been wondering how well it would hold a charge while docked, so last night I fully charged both the tablet and dock then left it closed from midnight (UK time.)
It sat on my desk like that until I got home from work at 17:15 this evening, opened it up and the dock was showing 99% and the prime 98% full charge.
I've not changed any of the power settings or docked settings yet, so that's running out of the box (post updates of course.)
Of course it's possible the battery indicator isn't accurately reflecting the amount of charge it's used, but based on those numbers it doesn't seem to be a problem.
Somewhat anecdotal evidence, I'll test it out a bit further this week and see if its actually entering deep sleep (presumably it is.)

This has been my experience as well. The dock does not seem to keep the screen any more awake than when they are not connected. I do love how the screen automatically comes up when you open it and turns off when you close it.
Man I love the two of these things together.
I have the Asus setting checked but my tab is like a vampire and sucks the dock battery dry in just a few hours time. There needs to be a deep sleep setting. It isn't really practical for me to disconnect the dock every time I stop using it. That takes away a good part of the portability aspect.

Do you mean when the Prime is completely charged (which is what this thread is about) or when the dock is charging the Prime? Because the dock battery IS smaller than the Prime's, and thus it will certainly discharge at a faster rate when charging the Prime's battery (until it runs out, of course).
Indeed, the dock shouldn't discharge AT ALL until the Prime is at 70% or less. So, if your Prime is 100% charged and it still sucks the dock battery dry in a few hours, then you're experiencing some other problem.
Again, this is about the Prime and dock both being at 100%, and whether or not the Prime enters deep sleep. It's not about the impact on the dock battery when the dock is actually charging the Prime from a less-than-70% state.

As I said in the post just before yours, if your Prime is at 70% or less, your dock will charge it which will definitely discharge the dock pretty quickly. If your Prime is at 100%, then it shouldn't be discharging the dock at all. If it is, then something's broken.

There is a ton of information about this throughout the forums. Use the search function next time.
What you will find is that due to the batteries being Lithium-Polymer, the dock (and the wall charger, for that matter), will charge the tablet only when the tablet reaches at least a 30% drain. At that time, it should recharge it back to 100%. This will keep the LiPo batteries from damaging short cycles.
Just exchanged my C2OK serial TP at Best Buy because of the bad WiFi battery drain and got the C3OK serial ATP. I also noticed that it does show GPS on the box. Did Asus remove the GPS from the box in the prior TP? I didn't check the C2 box if it showed GPS.

I don't think it even really matters anymore. as far as i know, every box still says GPS. could be wrong though.
I have a c2ok also. How do you know that it has a battery drain issue? it appears like the battery on mine dies faster than i think it should, but maybe i am just paranoid. what sort of symptoms did you see on the battery drain issue? what sort of life was bad enough to know you had a serious problem?

After I got the .21 update, I noticed that I could no longer get the same 10 to 12 hours I was getting. At first when I got my TP I tested for a weekend and was able to go through the whole day basically almost none stop using the TP, and after the .21 update I was only getting 6 hours and that was pushing it. A few times it even drained on its own just sitting and me using it for about an hour.
I did some test and posted in the threads that I was able to narrow the drain to my home Linksys router. At work I have set up a Cisco router for the office use and I can go 8 hours with no problem. The .21 update might be trying to have the WiFi push more to connect and depends on WiFi routers, its causing more battery drain on the TP. This is just my case, can't say if this is happening with others.

Maybe Asus has improved the GPS and WiFi on the C3OK models and feel confident that the GPS and WiFi is much better.
I just tested the WiFi and it is way better than my C2O was. On the C2O, my signal was in the -79db and in the same place and same router with the C3OK model, it is from -58 to -61. This is nice. For some reason the back of this transformer prime feels much thinner than the previous version. When you tap the back it feels much thinner by the sound. Maybe its just me.

Hey guys,
Has anyone figured out a way to limit the charging from the dock to the tablet? As in not for the tablet to charge at 75% battery life, to drop it to say 25% the only charge to 50% to try and preserve the life of the batteries, as it seems the tablet will lose battery life due to a 'constant' charge
like a laptop you can set power settings up so that your laptop doesnt charge unless needed when plugged into the power source.
I just want to know if it can be done

I honestly never thought of this, but I gotta say that's a really good idea. What's the point of charging through the dock if eventually, the battery in the dock is gonna run out? I would love it if anyone could figure this out.
Likewise, i know it's somewhere in the power settings yet its fnding out how to do it, and hopefully you dont have to root it or be running a custom rom, if it could be an app install that does it even better, there are some apps that look at the power consumption yet this one would be to turn off / edit the charge protocol

From what i have seen even when keyboard dock says no battery (after completely transferring it to tablet) it runs without any problem. It either has some reserve or gets powered by tablet.

By charging from the dock when the Prime runs down to around 75%, it keeps the Prime charged up longer as in for around 18 hours instead of the 12 hours the tablet alone is rated to deliver.
Even if the keyboard dock becomes completely depleted, it will still work fine as it draws current from the tablet's battery even while it is "charging" the tablet.
The battery in the dock is only there to charge the tablet, it serves no other purpose.
I interpreted the question as 'this mode of operation is bad for the battery cause it can only cope with XXX charge cycles'
I think it's a limitation in the charging circuit that makes it impossible to run off DC input only (with the battery offline), and the battery technology prohibits a constant float charge of the cells.
It might be possible to tweak the end-of-charge current to closer match the 'on' consumption of the tablet (but in what state), so 95-99% charge takes much longer, but probably only in the kernel. It's not worth the effort for my money...

Pretty sure it just draws power from the tablet once the dock battery is dead.

Just about a week ago, I noticed my Prime's battery wouldn't charge above 74%. Sometimes it reads 63% and won't charge any further. The keyboard can go to 100% but prime stays at 74%. I have drained the battery fully, but it still only goes to 74%. I'll be doing an RMA for my prime in a few days (wifi, camera, mura).
Is this software or hardware? Should I just add that as a problem alongside the wifi, camera and mura? Thanks.

Can someone tell me whether ASUS actually does *fix* or *improve* WiFi signal strength when sent in for RMA. It's just that the tablet is actually unusable without a piece of tinfoil on the bezel. Thanks.

What did they repair in order for the tablet to charge correctly? Before I had mine sent in for repairs due to an accidental brick; mine had also been showing some inconsistent battery readings. The tablet would show a certain percentage, but stay at that same percentage for about a minute, while it had eaten up about 3-5% from the dock before there were any noticeable changes in the tablet's overall charge.
AW: Transformer won't charge above certain battery %
Have you tried loading the Prime overnight while it is switched off? I do that from time to time, and until now it has always worked to get 100% charge back. Never could get completely rid of the problem though...
