[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.

Thanks for that .

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.

[Q] Dock charging issues?

Anyone seeing a charging issue on the dock?
Here is what I'm seeing. My tablet is at 80% charger...so I plug it into the dock which is at 98% charge..but for some reason the dock doesn't charge the tablet. I reboot the tablet with the dock connected..still the dock doesn't charge the tablet.
I take the tablet out of the dock and reboot then connect it to the dock again then I'm able to see that it is charging correctly.
Anyone else see this issue? I don't know if the problem is the dock or the tablet or the software. I'm assuming that this is software related otherwise it would never charge.
Thoughts?

Same here. Are you plugging into a wall or pc? I found by using the wall charger it fixed the problem.

neither. i'm just trying to let it charge from the dock and it won't do it unless i reboot the tablet separately and then reconnect it to the dock. even if i keep the tablet on the dock and then restart...it still won't charge.

The dock starts charging the tablet when it reaches 70%.

oh i see. but i do think i have a problem with the tablet..i try to charge it directly and now its not charge. it was at 77% without the dock..plugged in the charger and no charging. very strange. but if i connect the tablet to the dock and then charge it then it appears to be fine.

I am having this problem as well. Did you find a fix?

[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??

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%
Edit: Formatting got messed up, but I think you'll be able to figure it out

Dock Battery Problem?

Hello, all. I just picked up a dock from Best Buy last night and am having some interesting problems with it. When I first connect it to the Infinity, it always shows that it has 56% battery life. Then, after a few minutes, it shows 0% battery life, but still works fine (I'm typing this on it right now, as it says 0% battery life). I charged it over night (with the tablet docked), so I figured it would've charged completely (tablet was fully charged, as expected). I am on CleanROM 2.7.2, so part of me wonders if it's a ROM (or kernel) thing. Has anybody heard of this or had experience with it? What should I do to try to remedy the problem?
Thanks in advance for any insight!

Been charging all day... after searching, I decided to try a cold boot with the Infinity docked, which didn't work. I charged the dock and tablet together afterward, with the tablet powered off... tablet is showing 100%, dock still says 56%. Installed "dual battery meter" to see if it was an ASUS widget issue, but the aftermarket widget shows 56%, too.
Should I just suspect my dock is defective?

I think you got a bad dock and would take it back for exchange. I have had zero problems with my dock/keyboard. I unpackaged it, connected it to the tablet, plugged it in, both dock and tablet fully charged without issue.

Exchanged. New one is charging. I'll post back with results. Thanks for your insight!
Update: Charging light went green and the widget is showing the dock has a full charge. I guess I simply got a defective unit. Thanks again!

How much is it from Best buy? 149 $. Does it real t700 dock ?
I want dock too, but look ebay over 149

It is $149.99 at Best Buy. It is the TF700/TF201 dock (as opposed to the TF500/TF700 dock, which I believe is supposed to be forward compatible, but with no other differences in functionality).

one thing to note, although the battery in the dock can go completely dead, you will still be able to use the keyboard to type. It just wont charge your Infinity.

Will the dock cause increased battery drain on the Infinity if you use it when it's dead? (By the way, thanks for responding. I suspected that a dead dock was still usable, but had I known that, I'd have been more confident that my dock was defective from the start).

[Q] dock charging issue - not reaching fully charged

My dock had worked fine when i initiallygot my tablet, however the docked tablet now only charges to 93 percent. Looking at the battery app it shows that the tablet charges and discharges around the 93% figure. I initially thought this was due to the fact that the battery in the tablet was getting older or needed calibrating. Plugging just the tablet on to the charger allows the tablet to become fully charged. Any ideas ?
Cheers
Grant

Dock will only charge tablet up to 90%

At my tablet, I haven't reported that behavior. The dock charges all the time up to 100 percent.
With dual battery widget, I'm monitoring the batteries. Do you use any similar tool to report the battery stats? Do you use any mod?

my dock also charges it up to 100!
