Dock battery drain over night,... - Eee Pad Transformer Q&A, Help & Troubleshooting

I charged dock alone until green led showed, docked tablet (tablet has around 40% battery), closed lid and left overnight.
I woke up, tablet was off, and dock battery was 0%, tablet still has around 40% battery.
This is 3th time it happened while tablet was docked.
Any idea what should I do to find out what is causing it?
Thank you in advance

Are you on Android ICS? This was a common problem with the dock and the tab not being able to deep sleep. If you have a rooted tab try a new ROM. I had battery issues with the all the ICS variants (Early) and finally settled on the CM9 w/o out cornerstone as a daily ROM.

I am on ricardos CM9s, now its Megatron and hopefully ill not have this problem.

[Q] Tablet and Keyboard Dock battery drains when turned off???

I have had the tablet and the dock battery's drain all the way while connected and with the tablet turned off. I do have the latest firmware for the tablet and the dock.
Has anyone else had this issue?
The battery dock still has draining issues, even while off. I'm not sure why your tablet drained as well -- perhaps the dock started to charge it and tablet turned on due to it? or maybe the tablet started to charge the dock while it was draining and ended up both being dead.
yeah Im really not sure what happened but I do know when I went to turn on the tablet it started up and only had about 13% battery left when it was fully charged when I turned it off.
Check your wireless disconnect policies, if its set to Never then that might explain why.

Im not sure where to check that.
OFF as in you held the power button until it asked if you wanted to shut off, or SLEEP, as in just tapped the power button (or lock button on the keyboard)?
The Lock key on the keyboard, or just tapping the power button puts the unit in SLEEP, which is not really sleeping, it just turns off the screen and depending on your wireless power policy, WiFi may still be on. Apps still run. Stuff still communicates with the interwebs.
off as in i held the power button and hit shut down.
Mine is doing it as well. Did a complete shutdown yesterday after fully charging both the pad and dock. Just turned it on and the dock is blinking orange. I also had the WiFi disabled. Even when you do a shutdown it seems something is not shutting down.

ASUS never said that they fix the dock battery drain issue while tablet is docked and powered off. Have they?

im not sure. At least i know its not just me.
I hope they push the update where we can see the battery live for the dock soon.
Mine is doing the same thing. Keyboard was charged when I closed the lid and then blinking 6 to 8 hrs later. Wasn't doing this with firmware .12 with the keyboard battery indicator. I really hope they bring back some of the .12 features soon.

My keyboard dock no longer seems to hold much if any charge, I left it charging yesterday until the keyboard dock light stopped flashing and stays on steady (I assume that means its full) and now 4 hours later the keyboard dock light is flashing and no longer charging the tablet.
if i recall, this is a known issue with the dock. When not in use, it will still drain the battery. If plugged into the tablet at the time, im pretty sure the tablet will drain also. I think asus is aware and i thought i saw somewhere that there will be a fix once 3.1 is out, that will put the dock into a very low power state when not in use.
so i guess we will see once 3.1 is out

I believe only Solid Green is full.
Interesting I've only when seen a solid orange light, perhaps that just means charging, will try again tonight.

Same issue. Had a fully charged dock and a partially charged Transformer.
Was very pleased to see the tablet start to charge when I docked it, and not so pleased when I got up in the morning and both were dead.

Just for the record, I have the same issue. Dock battery drains really quickly when turned off and in sleep mode.

that might be a good idea it might not drain as fast!
Does it help if I leave the tablet and the dock disconnected when turned off?

Weird dock battery probem

I've got the dock for 2 days now. After unboxing, I charged for 8 hrs following manual instructions. Used it with the Pad for some hours (I don't remember for how long) till it ran out of battery, charge for another 8 hrs last night. Then I left it undocked for about half day. As I was running out to a cafeteria, I just docked the Pad (which was in standby state), hop in the car, and now, when I open the pad, the dock's battery is completely ran out, 0%. My dock S/N is B80. Has anyone countered the same problem? What is happening with it? Thanks.

I believe that there are apps in the Market that will allow you calibrate your sensors.... Take a look - let me know if you can't find anything...

I've had some issues lately with the newer firmwares where the tablet refuses to go into deep sleep until it's been rebooted, especially if you leave the browser with tabs open for an extended period of time.
Been using CPU Spy to keep track of it. It doesn't really seem to be related to any specific apps (ran it this way for a week after a full wipe and not installing anything new on both stock and Prime 1.8.4) in that even with a nearly blank slate it will still do this. Haven't figured out why yet but a reboot seems to temporarily fix it.

I have tried to find but it seems there is no apps that can deal with dock battery calibration. Could you help to post the link? Thanks.
What's weirder now is that I undock the pad, charge the dock with stock power cable/adapter, after 2.5 hrs, the dock battery is still empty, red light keeps blinking. Is it a sign that my dock is malfunction?

Well, I found some suggestions in the link below, tried "Cold reboot" and the problem seemed solved, at least for now

Sounds like the issue you have is more to do with the dock not charging over any excessive drain.
Have you tried charging it connected to the tablet see if it fares any better? Otherwise if its still not charging you may want to RMA the dock.
your problem is no problem you can solve. when the dock is connected, the tablet is using the dock to charge its own battery. once the docks battery is depleted, the tablet will be at 100% still. you should still be able to use the dock till the tablets battery dies as well, but with a blinking dock light

so if you're battery is depleted in the dock does the battery need to be replaced? Is there really no other option?
My keyboard and mouse still work fine the dock just won't charge. The orange light blinks and the dock leaches power off the tablet.
I have a bit of electronics experience and I've tried every reset you can do to the tablet with the dock connected and tried different chargers.
The problem seems to be in the port, the computer doesn't recognize is as a USB connection, so it's not even getting power from there. I read somewhere there is an internal switch that causes the battery to not charge. I flipped the switch with the tablet inserted, while charging and not charging and a bunch of different ways and that didn't help it still won't charge. Do I just need to replace the whole battery?
Have you tried charging from an outlet, not the computer ?

Dock Battery Drain

I was under the impression that this issue was solved in the Prime model, but it doesn't seem like it. I adore my Infinity, but the dock is draining like crazy. Even if the dock is not connected to the tablet, for some reason it will drain to 0% in a day. It does the same when attached to the tablet and both are completely shut down.
The keyboard does not wake the tablet up when in sleep mode, unlike the Prime issue. The battery saving mode is ticked. Is this normal? It's odd that it drains when not connected to the tablet. Otherwise, it does its job, and charges the tablet. For the record, it is the dock that has TF700t on the box and TF201 on the label. Should I just exchange it for another, or does this affect all of them? Not liking that I can't leave it overnight and have a usable tablet in the morning.
That sure sounds like a hardware issue. My dock lasts *much* longer than one day...

Guess I'll be exchanging it then. Hopefully Best Buy takes ship-to-store returns in-store.
Obviously it will empty in a day when connected, but on its own? Nah, this indeed sounds like a rightful return to me.
peoparte manufacture.
Mine is doing the same but worse. Keyboard has only worked acouple times and drains quickly and even when tablet is disconnected its stillshowing the the docking connected 0%. Whats worse is i paid a premium price for a tf201 dock with a tf700 compatible sticker when i couldhave just bought the tf201 one for $99. Add to this i bought them online from Amazon USA and paid for fedex to where i live. Australia!!!!! Now what. I cant even get it to check the keyboard firmware version.
I fully charged my tablet and dock last night after draining both batteries over the weekend. I'm about to go to bed at 1:30 AM and my dock is at 16% and the tablet is at 71% battery life. This is with lite to normal use like surfing the web, listening to music, checking e-mail and watching a couple of videos. Now, when I first connected my dock (fully charged) to the tablet, it did drain the battery overnight, but it that only happened once.

Dock Battery Draining

Hi Guys,
I remember reading a post about this before but can't bloody well find it
With my tablet docked, they keyboard battery is draining much faster than my tablet resulting in a useless dock fairly quickly i.e. 0% in dock vs 80% in tablet. This seems quite a gap - I'm running stock, not rooted. Is there anything I can do to improve this? I don't remember the charge gap being so vast in my first TF700.
Any advice/suggestions are most welcome.
Thanks.
Sent from my ASUS Transformer Pad TF700T using xda app-developers app
Been discussed before. Dock still operates at 0%, no need to keep a charge in there. It acts as the sacrificial battery, making the tablet use that power first, so if you so choose, you can continue using the tablet w/o dock or with dock and get the maximum battery life both ways.
Thanks Nick, I thought I noticed my keyboard wasn't working before when at 0% but will give it another whirl tonight. If it does work then bravo on Asus
i recently bought the dock and i also find the battery drain rather strange. i always turn off wifi over night and the battery of the tablet usually stays exactly the same, e.g. if i fully load the tablet before going to bed, i have like 99% in the morning without any drain.
yesterday i went to bed with dock 80% and tablet 85% and wifi off. today i find the dock left with only 40% and the tablet with 82%? is this normal? i guess i have to take them apart all the time over night otherwise it just drains too much
Definitely is not normal - I leave mine docked overnight with wifi *on* and I only get a percentage or two drain...
To start with, 'd look (with CPU Spy) to make sure you tablet is deep-sleeping properly.

That's odd. Maybe some process kept running overnight.
Check that the following are set:
- GPS to OFF
- IPS+ OFF (set it to IPS mode. + drains 10% or some overnight, even when off.)
- Mode to Power Saving!
- Shut down all active processes (taskmanager has this convenient one click clean.)
- Check that media players have shut down properly in the Settings/Apps/Running apps menu. Also make sure they're not still cached (VLC tends to do that...)
I think that this is normal behavior. I notice that after using the device for a while, when I shut it off the dock battery actually charges the tablet battery. The charge light on the tablet even indicates that this is the case. I believe that is by design.

The charge light is indicating the tablet is (primarily) running off the dock battery. EDIT: although this is in essence a correct statement, I have paid more attention to it and noticed the dock does indeed charge the tablet (when not in use) -- it's a few percents, but nonetheless, it charges. Mea culpa..
The capacity of the tablet and dock batteries is different, so discharging under load will differ as well. I guess the behavior you are seeing is by design, and, to some extent preferable to the situation I have had since the beginning: my tablet depletes faster than the dock, at least initially, and that was what most of the early adopters were seeing, as well. This of course led to some discussion.
The behavior we noticed seemed somewhat counterintuitive, since it meant we would have less battery capacity on the tablet if we would choose to undock it -- as opposed to your situation, where you have as much battery capacity left on the tablet as possible when you choose to 'travel light'. I'd prefer it that way. ; )
So, the dock depleting significantly faster is nothing unusual nor anything to worry about. I do have to concede, though, that my battery drain is far less than some in here report -- it has been going for three and a half days with moderate use now. (That's OK, I guess, given the fact that I currently am in nightshifts and do not have to time to tinker as much. Even when I *am* tinkering, though, the batteries routinely carry me over two days, easily.)
My dock and tablet have weird battery usage.
So my problem is really weird I think, but maybe you guys can confirm or offer any fixes. I have tried charging the tablet and dock assembled through the dock port and gotten both batteries to 100%, but then while docked, the tablet's battery drains faster and the dock;s remains at 100%. As the tablet's battery gets to around 70%, the dock's will start to deplete but very slowly. The dock will only go to 70%, and the tablet will drain completely to 1% and then shut off even though the dock still has 70%. I then undocked the tablet and just charged the tablet back to 100% without doing any charging to the dock. After docking the tablet, it shows the tablet at 100% and then the dock at 70%. This time the tablet drains to 1% and then shuts off with the dock still at 50%. What's going on here or is it normal or is there a setting that I'm missing? I thought the dock was supposed to extend the tablet's battery life time??

[Q] dock (keybord) battery drain

I use the dock (keyboard) always so I'm not happy that the tabled drains the keyboard.
When the tablet gets around 85% battery it's going to drain the battery from the keyboard till it is out of battery.
Is it possible to let the tablet drain the dock if it is around 25%
I have this problem since the first day (stock rom) I went to custom rom's in the hope that it was a bug of Asus.
Maybe some can help me to fix this. It is annoying that I have to use power after 1.5 hours of use
Thanks,
The keyboard works with emty battery.
my keyboard battery is dead right now andit still works perfect mate
