[Q] Charging with the keyboard dock - Asus Transformer TF700

New tf700 is in transit right now, but I have a question I haven't been able to find an answer to yet...
If you plug the charger into the keyboard dock, you will obviously charge the dock battery. And the same for the infinity itself. But if you plug the charger into the dock and then attach the infinity to the dock, will it charge both the infinity and the dock?

Yes it'll charge both. Idk if its both at the same time or the dock then the tab but it does charge both.

If your docked, it will charge both the keyboard dock and the tablet the same time.

Yep, but @OP keep in mind that it does not DISCHARGE at the same time. When using the Infinity + Dock, it switches the powere source. Noone has written an app to change this (IDK if its too low level either). Makes more sense to deplete the dock when plugged in, and then rely on the tablet later. I understand what they are getting at (their way helps a lot if you use them both together a lot) but they should give the option to choose.

So, if it's not plugged in, which power gets used first? The keyboard or the tablet?

Dock discharges first. Don't know why anyone would want to change that method of charging. Even though I take the dock everywhere with me, I sometimes remove it so I can use the tablet only because it's handier that way.

The keyboard actually charges the tablet when it's not plugged in.

I dont think so. I notice BOTH batteries depleting when I have it on the dock.

If makes sense if you only use your tablet a lot more than your dock. When plugged in you would want to conserve as much battery in the tablet as possible so the "charging method" is to use the dock only when connected. or charge the table, effectively making the dock's battery a refill, not a supplement. If you use them both together, it makes sense to alternate. It just depends on usage patterns.

Thanks

I don't know what you are seeing, but when I have the tablet docked and not plugged into the charger the tablet charges and the keyboard dock is depleted. I took a screen shot to show you what I'm seeing. It's plain as day that the keyboard is charging the tablet. Of course now the screen shot won't upload.... I'll try an edit after I post.

The tablet will drain first to ~70%, then the keyboard dock will charge the tablet back to ~90% this will continue in a loop until the dock is drained and report back as 0% battery left on dock.
The reason your seeing keyboard being drained is because lithium-ion battery overtime will slowly drain ~1% probably couple hours or so.

It's not quite that simple. First, I've had my dock show 0% and blinking orange on the LED, indicating I should charge it. I still used it actively for almost a day, including the USB port from time to time. So either the tablet is then powering the dock's keyboard and ports, or the dock battery has a "reserve" battery capacity for internal use (e.g. only the dock).
It's slightly annoying seeing that 0% and blinking ("OMG, CHARGE MEEE") yet I can still use the dock without any issues.
I'd just like to see some settings/configuration parameters for dock usage. First, I don't want it to complain about 0% battery until it's actually getting low. It could just say it's not charging the tablet anymore, and keep the warning lights for when the dock's actually nearing empty.
Also, while Li-Ion batteries discharge over time because of the internal resistance, we're not talking 1% every couple of hours. You have a defective battery in that case, or a very old one.
The self-discharge of the lithium-ion battery is 5% in the first 24 hours after charge, and then reduces to 1% to 2% per month thereafter. The safety circuit adds about 3%. High cycle count and aging have little effect on the self-discharge of lithium-based batteries. A lead-acid battery self-discharges at only 5% per month or 50% per year. Repeated deep cycling increases self-discharge.

Tablet discharges to about 70% +/- and then the dock charges the tablet until the dock is completely discharged, then the tablet discahrges again.

[Q] Asus TF Keyboard Dock not holding a charge

I'm wondering if anyone has experienced this. So far I've tried charging the dock for 9+ hours and when I unplug it, the LED still starts flashing as soon as I unplug it, indicating less than 10%~ battery left. I don't think this dock ever got a full charge ever.
Am I doing something wrong, or should I RMA the dock?
Bump, see if anyone knows the answer.
Is the charger getting hot when you plug it into the keyboard dock?
No, it doesn't get any hotter, but I know that it's passing power to the tablet, since the cable goes into the Mobile Dock and the Tablet is docked, the tablet gets a charged to 100%, but Mobile Dock doesn't
Remove the tablet part and just charge the dock on its own.
yep. charge them separately. i believe that if they are connected the tablet fills to 100% before the dock even starts to charge ....

I got same problem too.
but the charger is hot while I charge tablet or dock or both together.
dock is not charge, it always 0%.
sorry for my bad on english
Is the dock FW up to date ?
TBH .. i'd just RMA it, if its under warranty, just get it sent back.
P.S. Download the dual battery widget to see what it displays for the dock power ... but still RMA it.

[Q] Asus Eee Pad Transformer charging question

Hi,
I recently got my Transformer with keyboard dock a couple of days ago and am very pleased with how it's been performing up to now (updated to 3.1 soon after I got it ). I've got one question though (not sure if anyone has tested this): if you have the keyboard docked and you plug the charger into the dock, will both the dock and tablet charge in one sitting? Or does the power not get passed through somehow, meaning I have to charge each device separately?
Thanks.
Regards,
Jon.
Basically yes. The charger will charge whatever needs charging. I have the user created dual charging application that shows me exactly what's happening, and that's how it happens. It's the best case scenario. The ASUS engineer who designed that part of the system was wide awake when he / she was working on it.
Bye.

Just a heads up, you're not going to want to leave the tablet docked to the keyboard when not in use as it drains the battery very quickly.

When you say 'not in use' I'm guessing you mean when the tablet is switched on and left alone, right? Or does the same thing happen in this scenario even with the tab switched off? (Probably a dumb question lol )
problem with charging transformer
hi i have problem with this baby transformer ...
when i plugged charger with ac power to tablet charge indicator blink 2 time and then charge led in dock turning off
does it charge now or tablet or dock has problem ??
thanks in advance if anyone with experiences with this tablet aid me .
I think what you're describing is the "no power" light which pretty much says that the battery is completely dead, give it about 20 minutes and the light should (hopefully) come back on.

My charging saga
Here is my charging saga,
Received my TF yesterday (along with the keyboard dock), thought I would boot it up for a quick look. It did not have enough charge to that. Put it on the charger, wasn't sure it was charging then but as mentioned in above post it was getting something cause it came on for a brief moment. After 8 hours I powered on the TF, booted up no issue but I had only 38% charged, but it wasn't showing it was charging (unless I overlooked some kind of icon). Quickly installed dual battery app, it showed battery was not charging. So, I put it on the dock (did not want to I wanted to sell the dock, it was free with the purchase) anyway, the dock was drained also but at least it showed at that time it was charging both. Will see what next after work.

Tf201 Dock won't charge

Just bought a used TF201 dock, but Im not sure it works properly! How do I see the firmware version? How do l see how much the battery is charged on the dock? The widget with both batteries says 0% in the dock even though it has changed for many hours.
If I press on the Dock Connected sign it just says 0%. The LED lamp of the dock flashes red when its charging, not constant red as the tablet does.
Is the dock defective or why won't it charge? Does it need firmware update? I can use all the other functions of the dock BTW.
It says 'TF201-DOCK-0207'
is that the correct firmware? How do I update the firmware?
That's really weird. It should be solid red when charging the dock. Im assuming you tried a reboot with the dock plugged in. If you plug the charger into the tablet does a charging insignia show up? If not then you probably don't have enough voltage to charge the dock as you would be "trickle charging" the tablet
If its not a voltage issue then you may have a bad charger, bad dock keyboard or bad tablet. I would first test the charger and tablet first. If that proves to work I.E. the tablet charges then I would move the tablet and charge the dock keyboar. If that works then insert the tablet into the dock keyboard and see if the charger will do both. Remember that the tablet will NOT charge the tablet with. It's battery until the tablets. Battery goes below the 70% threshold.
The adapter charges the tablet with or without the dock. The dock however doesn´t recharge whether its with the tablet or not :crying:

By what you're describing you aren't actually charging the dock is what people are saying. Usually charge is constant orange/red not flashing. If it is flashing when you are charging something is wrong. Does the dock go to green when on the charger for a period of time like a few hours? If not it's not charging.

The dock doesn't charge. No matter how long its in the tablets charger it just blinks red. Even after being charged all night it still flashes red. No constant red or green.

Sounds like the dock is bad. If it's under warranty send it in but don't tell them you're using it with a TF700 just say it won't charge with or without a tablet inserted

[Q] Dock + Tablet charging behaviour

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??
Sorry to butt in - I logged in to ask the question....

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%

can I still use the dock when the battery is empty?

thread. just wondering, can I still use it if the dock battery is empty (when it's attached to the tablet)?

Yes, you can.
Yes but bear in mind, if the battery drops to 0%, you might struggle to get it to charge again
noted. thanks for the hints. I always bring charger with me. I wish I could control the charge when using the dock. for example, let the dock charges when the tablet's battery is near 10% or some sort. oh well.
Yea the tablet always takes priority when charging via the dock, the way it is designed is to make sure the tablet always has the most charge under all circumstances - so when using it docked and on battery, the dock will drain first - when docked and charging from the wall, the tablet charges first / fastest
The way I use mine is I charge them both up full and use it docked until the dock battery is low - then I undock and charge the dock on its own while I use the tablet battery - the dock generally always reaches full charge before the tablet battery runs out, then I can dock again and keep using them both on battery again - that way I get the longest possible use from the tablet before having to charge them both back up from the wall
it's also worth mentioning keeping the tablet docked will run both devices down. It's hardware-related, so best to leave them undocked until you run the tablet to 10% or so. Best results I've discovered.
