So, I just got my keyboard dock. but it's for tf201.
I choose it because a lot of people says the keyboard dock that originally for tf700 (ad-01 if i'm not mistaken) has a plastic backing.
my question is,
when I plug a device on the usb slot, whether it's a flash drive or a portable hdd,
and i open a document. then if the screen turned off, the device stop working.
for example, if i open a document that saved in my flash drive, and i got distracted and the screen turned off, when i turn on my tablet,
my apps said that the document cannot be found.
this is only a minor issue, but still it's annoying
is there someway to disable sleeping mode for usb, like what we have for wifi?
Power regulation to the USB port is done by the tablet. With the tablet off, the dock goes dead. This has been the case since the first Transformer.
I encounter the issue often, as I use it to charge my phone on the go. Nothing to be done about it, though, as far as I know. The dock itself doesn't power the USB, the tablet does.

really, that's sounds pretty weird to me, considering the dock have a battery inside.
but if that's the case, i guess i'll have to live with it..
Does it? A USB port on a turned off laptop doesn't power anything either. Yet the battery is still there. It's actually rather normal.
It is the same as for the other external storage options: they are unmounted when the tablet goes to sleep in order to save power. Your batteries would go empty that much faster when it was not this way around.
I sometimes "took issue" with it when reading e-books off the microSD card. I have since gone over to data2SD and store them on the internal memory now. In theory, everything should be sluggish now until the microSD gets 'booted', but at least my e-book is there when I need it.
TL;DR: It indeed is 'normal' behavior, and is designed to extend battery life.

but some computer can charge when it sleeps.
and I found some thread in tf300 section that say their dock can do it too.*sleep/charge

Hi everyone,
so i have successfully RMA my dock to be repaired (B40 series) and got it back after 10 days. apart from a slight deformation around the SD card slot, everything is normal on the surface. there is a page stating that a new part has been used, 90R-OK06IO40000Y, supposedly, Dock IO_BD./AS.
so my question is, how can I make sure it has been repaired, I have already tried, and now with power saving mode, the tab's display does not turn on with any keys (not even the lock key), just by the power key on the tablet itself.
is there any way to do it? by the way, it asked to be updated immediately after I connected it to the tab, and now it shows a 213 firmware, is it new?
many thanks

Based on what you described, your dock is fine. It may have come back with an earlier firmware. Checking for updates is the best you can do.
You can put your tablet back in normal power draining mode if you require it to wake using a keypress (standby mode I think its called) but that's it as far as I know. I'm waiting for my dock to get back my own self.
I just sent mine yesterday. I think another sure way to check would be to leave the TF docked overnight in the new power-save mode. If I'm not mistaken there shouldn't be any significant drop in the dock battery. Before sending it in mine used to drop some 20-25% over 6 hours, when it was docked and closed (netbook style).
I appear to have bricked my Transformer.
I had a very successful dual boot Android/Linux sytem up and running. I installed with OLife Prime. However, this evening I finished what I was doing in Ubuntu, without thinking closed the lid and went for dinner. When I returned and opened the lid, the screen stayed blank. No amount of pushing the power button, or down volume + power, or even up volume + power, or connecting to the charger (no light even came on on the device), or even connecting to a laptop via USB rectified the problem.
I have read about some of the sleep issues on the Wiki, however everything there seems to indicated that the screen should flash on and off after closing the lid. In my case, it seems to be in a very, very deep sleep. I also read something on page 119 of this thread about deep sleep issues, but not really a solution around how to fix it. The Wiki said something about a hard reboot, but I think I´ve already tried that.
I had made a couple of changes to the stock Ubuntu install - I was running Lubuntu (Lxde window manager) to improve performance, and I also had Firefox writing cache to RAM rather than disk. Apart from that, a pretty standard install.
Any thoughts much appreciated because I am a bit stuck!

sounds like the battery is flat

Battery was about 80% charged when I left the machine and I only left it for about two hours. Also, it seems to accept no charge now - small light on keyboard dock near charge port does not come on when connected to mains
EDIT:
OK, it was a flat battery and I feel pretty stupid for crying wolf, but I still don't understand why.
I had the Transformer on charge for most of the afternoon. I was using Android and had pretty much 100% charge. I then used Ubuntu for about 2 hours before closing the lid for another two hours. After this the battery was flat. Super, mega fast battery drain!
The second part of the problem was the not charging part. Once before I had a problem with the Transformer not charging. To fix this, I took apart the charging block (remember the bit that plugs into the wall came in two parts originally) and gently bent outwards the two pins inside. Put it back together, plug it in and the Transformer started charging.
All is good once again, but I still don't know the battery drained so fast.

Dead charger? If it doesn't charge the tablet alone, or the dock alone, then that'd be my suspicion...

Beware closing the lid while using Ubuntu! The screen doesn't turn off. it looks like it's going to turn off at 3/4ths closed and then the display goes back on when the lid is completely down. I don't know for sure, but maybe that had something to do with it. the same thing applies for using Prime. if you lock the screen before you close the tablet, as soon as you close it, the screen comes back on.

Hi all,
So my transformer is bricked... completely been trying hard reboot, APX mode, holding power button, HDMI output the list goes on.
My only final resort is what I've read is draining the battery down and trying to recharge it? (Just need some confirmation here please if possible).
I've kept it in the dock, what I've noticed is, in the morning it was green LED now its gone to the amber so something is draining the battery I"m hoping I can get this down to 0.
How long do you guys think with both dock + pad and most likely on standby. Not too sure of the issue here
Anyway, I'm really reluctant to send this back to Asus RMA because in short:
1. First time I sent it, it got returned like a squeaky box. Every where you held it you heard a creak like it was about to snap. They didn't fix some things, and more dust ended up in my camera lens... + had to pay postage..
2. Half fixed, came back with wrong firmware (TW --> US). Could never update ever again, so microsd card updates FTW. No way was I planning on spending an extra month sending my TF back and forth... I paid extra to get the first batch B40 lol.. They replaced everything inside my TF motherboard, screen, Inside LED!?, buttons. Close to the works..
This happened right after I upgraded to ICS, it was the US stock rom booted up fine. my apps were updating, and as everyone else was saying about how some apps caused ICS to slow down I wasn't aware so I thought I would shut it down and power it back up. Since then it's not been able to come up ever again... Any suggestions?
What do you think?
Thanks in advanced.
One other thing, could someone check.. when tablet is docked and OFF. Do the usb ports still work?
Right now, when docked but "bricked" I can still charge my phone via USB.. If someone could test this that would be much appreciated as that could at least eliminate that my TF's battery is dead, right?
get it off the dock, hold volup+pwr, count to six and leave it for a couple of days. You can test if it's empty when you plug it in your pc via the cable. If you get the device plugged sound it means there's still juice there - unplug and press again volup+pwr. when you unplug it from the pc the tab shuts itself down.
if you don't volup+pwr before you plug in the usb it won't turn itself on. but it turns off automatically at unplug, as I said.
after the battery is down, plug the tab to the charger. I don't have the dock so I can only speak about the tab itself. Don't know why, but it works for me everytime. Hope it fixes yours, then, if possible, root and flash something.

Hi there,
Thanks, I'll that a try.
It's definitely charging and discharging, the battery brick is warm.. I've never had to connect my tablet to a windows PC. Today I did, it didn't make a sound.. Do I need to fully charge to be able to turn it on?
Normally not. I plug mine to the charger, I don't remember if it stats or I have to press power, when it boots the battery stays at 0% for several minutes.
Sorry for the late reply, did you manage to wake it? It's a long procedure of waiting mainly and can get annoying.
I'm still trying, earlier you had a thread about it poping up through the computer. What was the command you used in Linux?
Windows gives me nothign even when there was power in it.
Thanks.
Thank you sooo much!! It finally has powered back on, I hope this doesn't happen again.
My TF300TG was working fine yesterday, left it on charge over night - and now the display won't switch on. The power light is full green when plugged into the charger.
I've hard reset it, plugged it directly into a PC and when i attempt to switch it on - the PC recognises it - and after a minute or so, (i guess once its booted) the sd cards show up as a device - and i can browse their contents
I've tried to boot without a sim card or micro sd but doesn't make a difference
The screen remains black - I don't even get the asus logo, or even see recovery options
Anyone have this problem before? I'm guessing its a hardware problem?
I'm in Cambodia, there's no Asus support centre here (Closest is Thailand) or reliable post - so sending it back for warranty repair isn't a viable option.

When I had this, it helped to hold down the power button really long. Trying a couple of times usually the Asus boot screen appeared and it was all fine.
Not sure, if it helps, as you tried a reset before, but always worked for me.
Sorry, no other ideas...

I've had an Asus tab do it to me where the PC would see its content though the board is dead. At this point, it could be anything, from components to processor to NAND. If you have a micro HDMI cable, try hooking it up to a TV or monitor. Make sure the TV works with the tab as not all LCD TVs are created equal. Newer ones should do though. If it displays fine, at least you know the tab's lcd screen is not working properly.* If you're game, open the tab up and switch the service button off and leave it off for a few minutes. The reset button was supposed to do that too though I'm not sure for how long. This would refresh the tab, and sometimes that helps. Good luck.
* that the display is not functioning as it should doesn't mean it's bad. Short of being impacted, they rarely go bad just like that, unless the backlight is toast - in which case you'd see the display by shining an intense light onto the screen. You might want to check the cable at both ends (mainboard connector and lcd connector). Since the connectors are small, it's hard to tell if the cable fits all the way in. A loupe would help.

Pulled it apart and tried the on/off switch - no luck - took a look at the connectors and they seemed ok.
I broke my micro hdmi plug a while back - but will try to source another and give that a go
Cheers for the help!
Hi,
I have recently bought this tablet and it´s been working great until a recent update. After the OTA update my HDMI stopped working, I mean I get no video at all and of course no sound at all. It does not detect the device. I am in the latest version 4.2.1 and 10.6.1.15.3. I bought it in the US and did the update in spain( I guess it makes no diference but just in case I mention that) I also noticed that when connected to the keyboard it seems like it drains the battery of the keyboard (it even says charging) and the result is that the keyboards battery is completely drained and the tablet is charged until the keyboard battery shows 0%. It wasnt doing that before the update. Is this just a bad update or could be some trouble related to hardware?
I contacted tech suppport and they do not know what to do. They told me to do a factory reset which I´ve done several times with no luck at all.
I do not want to ask for an RMA, since I read about some really bad experiences...Any ideas? Is it only a software issue? Is there a way to check that the hdmi connector is ok (hardware)?
Do I need to downgrade?
Thanks in advance.
Aitor.
Go to your About Tablet screen and look at what Build Version you are on. Also, I would try it on a different TV or monitor to see if it behaves the same way. Try a different cable too.
As for the charging, it is normal for the tablet to use the dock's juice before using it's own. While connected, the dock will start charging the tablet as soon as the tablet dips below 70%. Because of this, the dock will always run out before the tablet.
taking it back to the store

Hi,
I tried different Tvs and cables with no luck. I decided to take it back to the store and get a new one, since the HDMI feature is one of the reasons why I bought this tablet.
I´d rather get a new one than get an RMA or try to root it and void the warranty. I did not know how the dock and the tablet behaved while connected.
Thanks for your time :good:
