Would it be possible to create a software mod that allows the keyboard dock to directly power the tablet instead of charging the tablet's internal battery?
According to Asus:
Battery:
9.5 hours; 25Wh Li-polymer Battery *3
14 hours pad with dock; 25Wh(pad) + 19.5Wh(dock) Li-polymer Battery*3

That means, the tablet uses:
Code:
25Wh / 9.5hrs = 2.631578947368421 W per hour
However, by using the dock to charge the tablet, it uses:
Code:
19.5Whr / (14hrs - 9.5hrs) = 4.333333333333333 W per hour
This means it's operating at only 60% efficiency vs direct power.
If it was possible to create a mod that allowed the keyboard dock to power the tablet directly, we should theoretically get:
Code:
19.5Wh / 2.631578947368421 W per hour = [B]7.41[/B] additional hours instead of 4.5
If you owned the TF201 keyboard dock with the 22Wh battery, you could get:
Code:
22Wh / 2.631578947368421 W per hour = [B]8.36[/B] additional hours instead of 4.5
Is this just wishful thinking or is it actually possible that we could realize this with a software mod? I'm no electrical geek, but it seems like if the keyboard dock battery is able to charge the tablet's internal battery, then maybe it's possible to bypass the internal battery and directly power the tablet itself.
It could be something as simple as an A / B toggle switch?
For example, while the tablet is docked, we can switch it to the keyboard dock battery, then switch it over to the internal battery.
This sounds like a hardware thing, the keyboard connects to the 40 pin connector which in returns charges the batter. There is nothing in the hardware/wiring that skips over the tablets battery and directly powers the tab.
Idea is a great theory for possibly extending battery life. Retrospect they have discovered graphene which is based graphite only it is a two layer molecule which stronger then steel and flexible and more electro conductive then gold. So lithium batteries have seen there day. When graphene is folded into grafold it becomes 200 to 300 times stronger then steel. Its uses should make most known periodic table elements look undesirable. Therefore now that we can extract mater into two layer molecules we are just at the forefront of this discovery. Who knows if this leads further advancements in periodic elements.
This material is already being heavily researched by the US Navy which has dumped 11 billion into research and development. As a result cell phones are scheduled to use graphene material for its flexible phones in the near future like 10 yrs or less.
As far as the usage of my Asus tf300 I see my keyboard battery offering me a additional 10 hrs a day. For gaming and Netflix, Hulu plus. I don't usually surf the web for more then 2 hours with my Asus Transformer.

Who knows? I know the port is wired to the main board with some sort of ribbon cable and then the power goes from the board to the battery. The reason for the port being routed to the main board is for obvious reasons(data transfer via cord) So from this information it would seem likely to power the Device directly, though with experiences with my phones I have never been able to power a phone with out a battery in it.

Check out my review/mod for the Anker battery. On Amazon for $59 and it works wonders, can be used for all sorts of devices.
http://forum.xda-developers.com/showthread.php?p=29330531
I use the Anker® Astro2 Dual USB Output 8400mAh External Battery Pack. The original transformer power supply uses a variable charger I believe that uses up to 12v/2.1 A to charge your device (it uses the max when your tablet has low battery life and less when it is near capacity).
My device is limited to 5V on either the 600mAmp or 2 Amp USB port. The tablet does not show itself as charging though when I use the device but my anker device blinks to show that it is charging. I turned my tablet off and left the charger in and the tablet gained a couple of percentage points of battery life after a few minutes.
I didn't know that the larger version could do 9 and 12V, feel like a bonehead for not checking. I got the 8400mAH version because I only wanted my charger to be about the size of my phone at max size otherwise I feel that the portability of the device is compromised (only have so much room in my pockets/bags).
If anyone else understands how charging works, I'd appreciate it if they could explain to me how using only 5v/2Amps would affect my TF700 infinity battery. Thanks.

Unfortunately 5v just isn't enough voltage to trigger charging (9v/2a isn't even enough). How long have you had your battery? Amazon has a good return policy, might be able to send it back.

Thanks for confirming. Sucks I bought the wrong one but at least the alternative is only a few bucks cheaper.
Welp, the Zagg Sparq 2.0 isn't even recognized on the tablet or with the dock. :/ Seems there's not enough output.
It works fine for my Samsung Galaxy S III, though.

Ok, new TF700T user here, coming from a TF101. I'm trying to figure out how charging works between the dock and the tablet. With my TF101 it was obvious..when the tablet was docked, it was kept at 100% charge by the dock. Simple. Now, with the TF700T and dock, I see that I have two icons on the bottom showing the charge of each. Nice. But, the charge on my tablet keeps dropping. My dock is at 99% and the tablet is at 90%. Why isn't the dock charging the tablet? What's it waiting for?
I HAVE seen the dock charge the tablet before, I just cannot for the life of me figure out what triggers it. Can anyone explain how it works with the TF700T? Does the tablet have to drop below some % before the dock kicks in or what? Or..do I have a defective dock?
Note that when I plug the charger into the dock + tablet, both batteries charge fine.
The dock is a TF700T dock mislabeled as a TF201 dock, but confirmed to be a 700 by Asus themselves.

Sorry not an answer, but a supplementary. I have the same query and I also wonder why if I plug in the dock the total time available on the battery doesn't change, should it?? Overall what battery time should I expect +/- if I have both connected??

I am strongly suspecting that there is a bug in the software related to the dock charging the tablet. A quick and easy way to trigger the charging process is to simply reboot the dock + tablet combo, not plugged in to the wall...when it comes back up, BING! it starts charging the tablet. My tablet was down to 70% with the dock at 99% and there was absolutely no charging going on until I rebooted the dock + tablet.
My current theory is that something gets fubared when you plug the charging cable back into the dock + tablet combo..when you unplug it, it appears the dock won't ever charge the tablet. I need to test this further when I get home from work.
Ok now I am certain that the dock charging is not working right on the TF700T.
The "reboot" trick does work, causing the dock to charge the tablet...but only to 90%. Once it hits 90%, the charging stops.
Is there some way we can submit "bugs" to Asus? Will they even listen? I'd love to know if other TF700 owners who have the dock are seeing this.

The dock does not charge the tablet before the tab battery is down to about 70%, that is the fact for my TF201 and TF700 and according to what I've read that is the way it's supposed to be (apparantly better for the battery than the TF101 setup).
I don't think your reboot did the trick, I think it would have charged anyways. But I'm not telling you for sure, just saying I think that is the way it's supposed to be (and is for me).
Actually, then the reboot did do the trick - b/c the reboot process consumed enough battery to drop it down under the 70% margin so the dock --> tablet charging process would kick in.
I'll test that and see.
The TF 201 manual states that the tablet will go down to 70% before dock charging kicks in and rechgarges it back to about 99% and then it will stop, go back down and keep doing this, in this way it keeps the tablet charged, the dock dorps to zero at the same time that the tablet gets charged to 80, then the tablet has a nearly full charge for you to use.
And I am drunk, sorry for the typos.
Yeah, your reboot only worked because the tablet's battery fell below the threshold anyway. It charges the tablet at 70% back up to the 90s, then stops, charges again from 70-90%, stops, etc. Your battery usage ends up having spikes, looking like:
_____|\______|\_________ <-- Dock discharges to 0% here
\___
\ <-- Tablets main battery hits 0%

Hi all,
I've searched the forums thoroughly and I couldn't find the solution.
I have a brand new transformer tf700 and keyboard dock tf201. They were purchased in the USA and brought over to me in Hanoi, Vietnam.
The charger will charge the tablet, but not the dock.
When the charger is plugged into the dock, there is no light. Also nothing happens when connecting the tablet and dock. No light on either, and the tablet does not enter a docked mode. So it seems like the battery on the dock is completely drained or the dock is simply faulty.
I've tried leaving it overnight for the initial charge (first thing I did), as well as different outlets and charging by USB.
Since the charger works on the tablet it seems obvious that the problem is with the dock, but is there any further troubleshooting I can do to confirm this 100%? Since I'm in Vietnam, sending the dock back for warranty etc.. is going to be very problematic and in fact its illegal for used electronic items to be shipped back into Vietnam. So I really want to know 100% for sure what the issue is. Vietnam is 220V / 50HZ and it seems the charger is rated for that.
I'm open to more advanced options such as using a multimeter.
Thanks.

It could be that the charger was meant for a newer version of the dock. Your using a TF700T charger with a TF201T dock.
It could just be a compatibility issue. If so just buy a TF700T dock or buy a TF201T charger. I hope this helps.

Very unlikely. I regularly charge my TF700 with the TF101 charger, and I am almost sure the TF201 uses the same charger.

Well I need to test this 100% for certain, because I can't send it in for warranty due to Vietnam's import laws, and the dock is not available for sale here at the moment. So neither of those options are viable
Like I said it has never worked but so far the only advice I have gotten essentially is "plug it in" as well as check the charger. The charger works fine with the tablet so I'm pretty sure that its not that, however I am curious about the mechanism by which it jumps from 5v to 15v and how it may behave in houses with or without voltage stabilizers.
Unless I've overlooked a very simple step I'm really wanting to move forward into a more technical analysis (ie: checking voltages / opening the dock).
Further info: the shop tested the dock before sending it (it was open but unused) and it worked fine.
So this strengthens the case for a charger/voltage/amperage related issue. Of course it could have been damaged in transit but it was DHL priority and appropriately marked so not too likely

It could just be you need a universal plugin to convert the amperage.

Well a universal plug as I know it is just an adapter. It doesn't have any step-up/step-down capabilities.
But if you mean a universal power converter then possibly, although usually they just provide 12v, not 15.
The supplied adapter should be fine though, because its rated at 110-240V (Vietnam is 220V) and 50/60Hz (Vietnam is 50Hz).
My only thought with the adapter was whether it was having problems stepping up to 15v as it charges the tablet at 5v just fine.
Question: Does trickle feeding the tf201 on USB work? Also does the light turn on for a trickle feed?

does this do anything.....
fully charge the tablet on its own, connect it to the dock, connect the charger (plugged in), restart the unit?

No I tried that before creating the thread. Thanks anyway.
Don't know if this has been asked yet, but does the dock actually work (not just the battery)? Can you plug it into a nearby computer and access the mounted tablet? Also, there's a widget on the tablet that can show if the dock/tablet is charging or not. Also, you mentioned trying power from different outlets. Did you try outlets in a different building (like a hotel or university)? I've seen from visiting Brazil that "standardized electricity" doesn't mean that everyone has adopted it.
From what you've mentioned, you really have 3 viable options of failure: Dock battery is bad, dock is completely bad, or incorrect power. If its the battery, then you get to decide if you want to rip it apart or not. If its completely bad, then you would probably need to send it back. Finally, if it just doesn't work where you are, it could be that the building isn't up to standards or even that there might be electrical issues in the building your at.

It seems like there is a trickle and the light does not turn on. I only tried it for about a minute but the tablet did show that charging was happening. Maybe later I'll try a longer test.

Not yet, but I will try that soon. I have a working voltage stabilizer in my house, as well as about 8 computers and 5 tvs etc.. Everything works very well and when I fixed some people's hardware recently it worked in my house but not theirs (due to my power supply being good) so I'm pretty sure that's not the issue. I will take it somewhere else though just to rule that option out.

Right, that's the conclusion I came to as well before posting.

Well, I believe that the tablet should find the dock even if the dock has no battery power. The battery of the dock is merely a backup battery for the tablet and not used by the dock itself for functionality. For this reason, I think you got just a bad dock. If you want to try to replace the battery (since you are closer to China and Japan), you are looking for a C21-TF201D battery. You will need a small torx screwdriver (like a T-3 or T2 - my smallest is a T-4 which is just barely too big) to remove the screws in the back and a Phillips 0 to remove the screws under the pads. Top piece can then be lifted gently and there are 2 ribbons underneath to fully detach the keyboard. From there you should have just a few more things to do to get to the battery. There's a teardown video here but the speech is almost inaudible and the music is distracting.
What I was thinking is that the dock was tested before shipment then it arrived nonfunctional. It leads me to believe that something was damaged during transport (derrr, yeah I know that's obvious just bare with me). If that something damaged was the battery, then there could be some leakage that has led to possibly corrosive damage to other electronics in the device. And that wouldn't be fun to try to fix on your own. If you want to continue trying to troubleshoot it, you might want to do it without attaching the dock to the tablet until you find out what is wrong because you don't want to possibly fry your tablet connector due to the dock acting unreliably.
You should probably start talking with your shipping carrier about the fact that the device was damaged and that you should be reimbursed somehow. This might allow you to get a new one through them or sufficient money for a replacement.

What can I say, you're a legend. That's just the kind of info I was looking for. I'll get stuck into it soon and let you know how it goes.
I also wondered about whether the tablet should connect to the PC via the dock but my thinking is that you may need a minimum charge to get through the extra circuity in the dock (all dem capacimataters and circamatronics). But yeah I see your point.
About the dock working before they sent it, I'd take that with a grain of salt.
Full disclosure: When the company sent the package, they forgot to include the dock altogether and my friend left America the next day. When I was talking to (screaming at) them, they said they were totally out of stock except for one which was opened but unused. They agreed to courier it (DHL express international... ouch) over to Vietnam (as it had most of its packaging so could be treated as new. ). Why that dock was already opened in their shop I wonder. Methinks it was probably already broken and they are trying to cut their losses (they already had to cover international shipping and 100% import tax so they lost out big time due to forgetting to send the dock. They knew I couldn't send it back from Vn either).
Once again thanks!
I've swapped in a mainboard from another dock that had a bad battery.
Now the dock dock functions fine, and the tablet connects and can be charged through the dock.
However the battery light for the dock just stays as orange no matter how long I charge it for. And it always shows 0% battery on the dock so it seems like the battery doesn't charge at all.
What areas should I check? Also if I use a multimeter to check the battery, is there any way to tell if the battery can hold charge (and the issue is somewhere in the connectors) or if the battery cannot hold charge at all?
I tried a cold boot, no luck. Perhaps an alternative is the mainboard needs some kind of hard reset to recognize the new battery? Or of course the battery could just be bad, like the mainboard.

Unfortunately, it has been years since I've used a multimeter for these situations so I wouldn't be able to help you out directly in that area. Googling for how to test batteries on other devices - like the TF101 dock or even regular batteries - could provide additional valuable information to help you in your experiments.
There's the possibility that it's merely a calibration issue where the dock has no knowledge of the battery's charge, but the fact that there's a constant 0% and the light stays orange all the time (never turning to green) then it leads me to believe it's a bad battery. Have you tried checking if the tablet continues to charge from the dock with no charger attached? If the dock charges the tablet in this fashion, then it's a battery data issue. Likewise, have you tried to use the dock without the battery, detach dock, then reinsert battery to see if that spurs the dock to reset its battery data? You might also look into an app or widget that will show you the battery output charge and all (like this). That's all I can really think of at the moment. Hopefully, from whatever tests you perform we can discover whether it's really a bad battery or something else.
Thanks for suggestions Alienedd. I ended up going back to Australia for Christmas so I quietly slipped the defective parts back in and made a warranty return.
Does the TF700 dock charge the TF700T Tablet or does it power the tablet directly?
A reviewer on Newegg said that the tablet is able be powered directly from the dock. This would be awesome!
But is it true?

Pros: ah the idea behind this product is lofty. i mean how can you set yourself a standard in industry when you product you push ends up like this? it isn't a bad dock. by no means. it just doesn't quite go from good to great. it stays behind; it could have catapulted the ASUS Transformer Pad lines into Apple killers. coulda should woulda. but let me continue by naming what it did correctly.
it seamlessly integrates itself the ASUS Transformer Pad TF700T. i mean it's just an awesome thing to do. it clicks on and you really can't screw that up. on the pad and the dock there are arrows pointing where the place the thing i mean how straightforward can you get? but you will be glad the arrows are there because for me it was a little daunting. i spent all this money and i was worried i would screw something up or place it wrong. but once you see the arrows you know how and where these two things should meet.
wow. just a definite "cool" factor. welcome to the 21st century type of "cool" factors.
another awesome thing: when connected with you pad, the dock's battery will drain FIRST. supercool. and if you have the dock charged enough it will CHARGE the pad. awesome. supacool.
ports: there is a usb port...which is awesome! with certain tegra developed games you can use a controller for said game! i mean that is super sick. kinda almost defeats the purpose a tablet but it is an option. doesn't have to be a controller i plugged a 2 GB flash drive and it recognized it no prob. more expandable storage? yes please.
and it also has a sd slot...another storage option. maybe you wanna store those snazzy pics you took. snap a sd card and there you go. kudos ASUS.
3 eggs only you say? and with these cool things? well. it does. prepare for coulda shoulda woulda.
Cons: this COULDA been the bombest keyboard dock you hard earned clams you just shelled for. almost but man oh man...
COULDA: the keyboard aspect is kinda disappointing. it isn't bad but considering i paid around 120 bones for this bad boy it isn't without gripes. the keys themselves depress just fine but for me there really is an audible "clack" to reassure i press said keys. minor gripe but a gripe nonetheless. the touchpad is decent but i expected more. sometimes two-finger scrolling doesn't. it doesn't when you expect it should. at least it looks sleek and is a nice idea. too bad it doesn't wow.
SHOULDA: this dock shoulda been included with the tablet. i know i might be unfair with some gripes but one does expect more for spending that kind of dough.
WOULDA: this woulda been awesome to the max if the battery on this baby lasted longer. i know it depletes itself before the tablet will and i know it will even charge the darn thing. but the battery doesn't last on this unit. maybe i got one that wasn't built properly idk. i sure expected the battery on this dock to last longer. maybe for a four hour use total i had to charge the dock twice. not as good as i thought it would be. rather, a big let down.
Other Thoughts: a cool cool cool idea but it just underwhelmed me in terms of battery life. pros really save this product but the performance to price ratio just doesn't quite cut it. maybe if it came bundled with the ASUS Transformer Pad it would have the awesome aspects hold up well. but the disappointed battery life high price beg to differ. maybe if ASUS just tried harder to execute it woulda been worth the money.

The dock starts charging the tablet when the charge drops below 70%, and stops charging at 90%. It does not bypass the tablet battery to power the tablet directly as far as I am aware. Though I must say I have not paid attention to that. Perhaps someone else knows.

Does the TF700 dock charge the TF700T Tablet or does it power the tablet directly?
A reviewer on Newegg said that the tablet is able be powered directly from the dock. This would be awesome!
But is it true?

My experience is that the dock charges the tablet once the tablet's battery runs below 70-75%. So if my tablet is fully charged, then the dock isn't supplying any power. But if I use the tablet and the power falls around 70-75%, then the dock's battery starts recharging the tablet. If I'm running a lot of processes on the tablet, then the tablet battery will deplete faster than dock can recharge, so the battery level will continue to go down, albeit at a slower rate.
And the dock recharges on the tablet even if the tablet is off. Let's say the tablet battery is at 60% when I turn off the tablet. If connected to the dock, then you'll see the recharge indicator light is on. When you turn the tablet back on, you'll see that the tablet's charge level has increased and dock's charge level has decreased.
As for tablet being powered directly from the dock, I would think that the dock is charging the tablet and the tablet runs off its own battery, but I'm not sure if this really matters in terms of function. I would think that if the tablet is depleted and the dock is charged, you can still run the tablet by plugging it into the dock and then turning it on but I haven't tested this. (Perhaps the tablet has a minimum charge level it requires before it can be turned on-in which case you can wait for the dock to charge the tablet to the appropriate level.)
Also, in the notification area, you can see the battery level of the tablet and the dock, and you can actually see when the dock is charging the tablet by arrows going from the dock battery level to the tablet battery level.

Thanks for the detailed info!
Do you know if we could use an extra charger to charge the keyboard dock by itself (undocked from tablet)?
I'm thinking of doing this so I can charge both the tablet and keyboard dock at the same time and reduce the overall charging time.

Yes, you can charge the dock separately. I sometimes do this when I'm watching a movie and the tablet is charged while dock is low on battery.
Did you decide to buy the tablet? I highly recommend Cromi/Cromi-X. I'm still on Cromi 3.4.7 (based on JB 4.1.1) as I really like the mods by lucious.zen (http://forum.xda-developers.com/showthread.php?t=2232715).

Yes, that's what I did when I received my TF700 - I used my TF101 charger to charge the dock, while the TF700 was charging with its own charger.

Yes! I bought a tablet and dock!
Office Depot has it for $380 + I was able to use a $25 off coupon from Staples bringing it down to $365 + tax for brand new!
I have a dock on order as well!
I wanted a TF201 dock for the bigger battery but those are so hard to find.

Congratulations on the purchase and the price! As for the dock, I think the tf700 dock's weight distribution is better so the tablet is less likely to tip over. Hope the games work out for you!
And when you get the dock, you may want to check out the white mouse cursor mod posted by RpR. I posted a modified image for the cursor in that thread.

Thanks! I love this tablet and dock combo! It's the most useful thing I own!
The ST8 battery on my K1 is now bloated and the back cover is popping off. Looks pretty shady and does not qualify for a recall.
Instead of replacing the battery with third party li-ion cells, which is what most people would do, I want to run my K1 without a battery going forward and only draw power while plugged in via the native USB connection. I don't use my K1 on the go anymore and don't want to deal with the longevity issue of li-ion batteries.
Anyone use their K1 without a battery?
Apparently the battery charge board must be kept as the bootloader checks to see if the stock battery is there otherwise it shuts down and doesn't boot?
I've read somewhere that people have soldered a resistor in lieu of the battery across the terminals of the battery charge board to fool the circuitry? But that seems shady as it will keep drawing power across the resistor as the charge board tries to charge it all the time and draw power across the resistor constantly.
What about using a combination of resistors and capacitors in series and in parallel to mimic the RC circuit equivalent of the battery?
Or some circuit that fools the voltmeter on the battery charging board into thinking the terminals have reached full 3.8V and to stop charging?
I'm only just looking into this today and still pretty green on all things internal about the K1. What options are there to run the K1 without the battery?
there are not really any provisions to do what your talking you are going to need to do some creative things i am thinking about open back and using 14440 cells in parallel. you will need to provide 3.7-4.2v to the charge circuit of the original battery the cell connected to it doesn't need be a cell it could be regulated power from another source. But IMHO 3d printer plus 5-6 AA sized li-mn batteries in parrallel.
