[Q] 4.1 + Dock + Sleep = Reboot - Asus Eee Pad Transformer Prime

Hello all.
Anyone seeing issues when the unit goes to sleep while in the dock?
I've been in the "i'm not having any problems" crowd until today. Up until yesterday morning, I was on stock but rooted ICS and was using Titanium backup to freeze (not uninstall) apps I didn't want. Everything was fine. When I saw the update available I just let if run OTA and that seemed to work just fine too. I used it all day yesterday and everything was still working fine though it did not seem as though I had any real performance increase from the update. I had also lost root in the process anyway, so I decided to do a factory reset and get a clean (not upgrade) install of 4.1
Last night after the install I used it quite extensively and was very pleased. Got all my apps set up and all was good. But....I was NOT using it in the dock. Put it in the dock just before bed time and hooked up the charger. When I got up this morning all was still good.
But this is where I started using it in the dock and the trouble started. While I'm actually using it, all is good. But if I put it aside with the unit open it eventually reboots just sitting there. But ONLY in the dock. NOT when its out of the dock. Here is the situation that seems to trigger it:
1. In the dock and not used for a while
2. Charger is NOT plugged in
3. Lid is open I.E. Thinking of it as a laptop where the screen is the "lid"
If the charger is plugged in, no problem
If the lid is closed when not in use, no problem
If the lid is open and no charger hooked up - problem
It seems to me like it has to be a power management/sleep issue?
Since I don't have root at the moment, I went ahead and uninstalled all my root stuff like SU, Titanium backup. Over clocking tools, etc - all things that did me no good without root

I can confirm that this is happening to me after updating yesterday. My prime has actually rebooted twice this morning while being docked. Maybe ASUS screwed something up in the dock drivers? This is very annoying and possibly a show-stopper for me.

I read in another thread there should also be an ota for the dock, maybe you need that first? I'm still on work, can't wait to get home and try everything myself

Not sure if you guys know this but it was an issue with JB for tf300 and for those of us on hairybean1.2 based on jb for the 300. For those if you have anything in the dock (sd card, usb hard drive) when it sleeps you can get sod or reboots. Hope thats the case for you because there is already an update for the tf300 to address that.
The temp solution if you didnt catch it is to take out the card or usb when you are not using it.

Hmmm. I do have a 64 GB SDXC in the dock. I'll give that a try right now and report back.
Edit. Hmmm again. I just went to remove the SDXC from the dock and discovered that in the quick settings (or whatever its called in the lower right corner) and see that the little icon with the red X that you used to be able to click to dismount the card is no longer there. So far its not rebooting itself after removing the card though.

I've been having the "reboot when in dock, lid open, power save engaged" issue, too. And I do have an 8GB SD card in the dock. I'll experiment with this when I get home, see if it avoids the problem. Aside from these reboots, I've actually been enjoying JB a lot, so I hope that's all it is. (Though obviously I'd like a fix, eventually - it worked fine under ICS.)
What should the dock's firmware version be at, anyway, after the upgrade?

It's not a total failure, they have given the devs a better platform to build on.

Hmmm. My dock is showing up as TF201-DOCK-0207 so I seem to have the updated version?
Removing the SD card did stop the reboots so that's an OK temporary solution as I only use it for movies. Hopefully that will be fixed soon.
But no matter what I do I no longer see the x to dismount the card - same applies to my micro sd in the prime itself.

That is the latest dock version. When you install the card does it show on the quick settings that a card is inserted?

Just an additional data point, my TFP hasn't rebooted once on its own since I updated 24 hrs ago. My TFP is always in the dock and is frequently unplugged. As I type this, its been sitting in the dock unplugged from power for 5 hours. My dock version is 207.

---

It only reboots or sods with a card in

My tablet is on a constant reboot loop, taking the micro SD card out and removing from dock has had no effect.
I think it is Google Now, it crashes as soon as the traffic report pops up.

---

Power button doesn't work?
My power button doesn't work... If I stay it pressed it reboots... But I can't take the tablet into sleep...
With dock inserted the same thing... Bue when I close the lid it switch off screen and when I open it wakes up ok....
And even... sometime my tablet switchs the screen ON for no reason...................... can anyone please give some advise? It is possible to downgrade to stock ICS ?
**** this update.

I can confirm it is not all units
TFP (bought it on day one from Gamestop store, 1st unit to leave store)
updated to 4.1 yesterday
Dock on 207
always have sd card in
No issues with SOD reboots.

I have the same issue. Tablet has rebooted twice while docked if I let it go to sleep and don't wake it up immediately. Don't really want to have remove my 32gb sd card as I use it quite a lot. I suppose I'll have to though

And without dock? You can put the tablet into sleep and out of the sleeping mode pressing the power button?

Ah, I love the geniuses on this forum. I was totally loving this update, until I sat here and got 4 reboots within the past hour. Lo and behold, I have the dock and a 32GB SD card in it. I guess for now, until Asus fixes this bug, the SD card is being removed. That is way better than constantly waiting for the reboot to complete.
Thanks so much for this thread! I love my Prime and am glad I don't have to start hating it like so many have.

it will come out of sleep while docked - but you have to be quick - if you leave it more than 1 minute it will power off while sleeping. I haven't tested it undocked - but I'm assuming it will work fine - as it seems to be the sd-card in the dock that is causing the issue
