Automatic Shutdown?

Hi, I picked up a new 7" Tab 2 a few weeks ago, and it seems to randomly do an automatic shutdown if i haven't used it for a while. Sometimes when picking it up after putting it down overnight, or after I've left it home, the tablet is off, not just asleep. It also doesn't seem to matter if it is plugged in to power or not. Is this normal behavior, or is there a problem?

I would say it's a problem. I've left mine for several days on and off the charger and it never shuts down. Are you stock?

Completely stock.

It could be a problem but, I've seen some tablets that have a setting to switch off after a certain amount of time. Check all your setting see if there's anything either ticked or highlighted by radio button to switch tab off

I have same problem one week ago, tablets restarts in my pocket two or more times in a day, since I installed cyanogen mod firmware al is ok, I was thinkin that may be an app is that make restart, not a hardware problem

Its software on your tab. Trust me lol. Wiping or getting another rom will probably fix it.

ASUS TF101 Does not turn on unless plugged in...

So... I cannot turn on my Asus tf101 unless I plug it in to a power source, once the screen lights up I can unplug it immediately and it functions normally when turned on. I bought this device refurbished from best buy a few months back, I dealt with the issue but now am looking to sell it. Any ideas on how to fix this? I have never rooted the device, however I have tried factory resets and cold boots.

Are you holding the pwr button long enough. If so,it sounds like the switch is bad.

I hold the power button for 12 seconds and try it with different variation holding volume keys. It functions fine when the device is powered on.

It could be a bad battery or your charger is only giving enough to power the device on. I would try a new charger first.

But once powered on, it functions flawlessly. The only issue is turning it on.

Do you have the keyboard docking station for it?
Are you on custom ROM or OEM?
What "app killers" are you running?
Some custom ROM's have had similar issues a long while back. maybe yours is getting that issue IF your running custom.
Keyboard dock, if you have it, does it do the same thing for powering on, where it needs to be plugged in to start the screen?
I only ask about the app killers because I had experienced a similar issue about a year ago due to an app killer I had installed. Removed it, and the phone worked fine. Put it back on and it reverted back to having to be plugged in to start the screen.
Have you tried a clean wipe of everything on the tablet? And I do mean CLEAN, no dirty flashes here (keep your pants on bud).
Lastly have you given the charge port a good ole blow out lately? Long bursts aren't really going to do any damage, but I would stick to short quick bursts of compressed gas, again NO VACUUM CLEANERS. They create static and the charge port is quite susceptible to static discharge.
I know your pretty intelligent, but let me put it out there again. DON'T be a fool and use alcohol on your tool.

This post made me laugh. I do not have the keyboard docking station. I have never installed any task killers as I do not believe in them. The tablet has been running the stock ROM the whole time and has never been tampered with.

And yes I have done a factory reset twice with no success.

But you never said if you gave the ole girl a good ole cleaning in the slot.
I would venture to say that you need to send it in to Asus or take it back to Best Buy (if your able to). It sounds like there may be a voltage issue with the digitizer or the inverter.
And NEVER EVER EVER Invert your digits while cleaning out the slot.
You also didn't say if you went deep up in the ole girl and gave her a good rootin.

I'm working with Asus right now and of course there's something wrong with my serial number. Nerve been rooted. Blew it out and that did nothing.

Please keep us posted as I am curious to know how ASUS customer service is to deal with.

Well, I am trying to send my TF to Asus to fix the problem and they are a bit annoying. I have just dealt with HTC before and that was wonderful, but here they have send me 4 emails asking me to wipe, to update and to do everything that I have already done, and after that they have sent me to another web to fill another questionary. With HTC I just had to told them the IMEI and in 4 days I had my phone back

I had similar issue with mine. It was one of the reason I took back to best buy and used the buy back.
I then picked up the Nexus 7.

I had a similar issue, do you use your device often ?
I figured out after a couple of months that each time it showed this behaviour the battery was in fact empty and it was in fact the root of the problem.
My transformer take much longer time to boot when plugged even with a full battery, and when it's empty it doesn't boot at all.
I must plug it, wait for it to be enough charged to boot unplugged, and do so. Then plug it back when started.
Considering that the transformer on stock cannot shut off when plugged to its keyboard (or even to USB ? Or is it just mine ? When I shut it off plugged to the keyboard then close it, it boot on again) When the tablet is left for several days unused the battery will be empty.

Yes I do. But even if the device is fully charged it will still not power on unless plugged in and I don't have the dock.

Ok, sounds to be a totally different issue then, sorry

Do the power and volume buttons work normally once fully booted? I have had similar issues, one was improperly seated power button, the other was a loose ribbon cable way down in the guts of this beast. Also, was this happening the whole time you've had it , or after a firmware update?
Right now I'm dealing with one that the screen won't stay on once I get into ics unless I'm plugged in. I went in and noticed that if the auto brightness wasn't set, it works. So I tweaked the settings in display time off when unplugged and uninstalled some screensaver app, and now it's working fine. It was probably the first thing, even though was already set to one minute. Anyway, just letting people know sometimes it isn't hardware. But the op probably is since he's done factory reset.

Had Enough.

I am totally stock and never done nothing to this bloody thing, done the update yesterday, andddddd it still takes about 30 seconds to turn on and it is still dropping the Internet connection. Let me ask you something, if you bought a brand new car, took it home and from then on it takes over 30 seconds to start it and while driving the engine cuts out now and again, what would you do.

I would join a support forum and whine about it. That always solves the problem.

I would first make an intellectually dishonest analogy. Totally.
Seriously, this takes the prize for the most unrealistic and unreasonable complaint of the month. The audacity of a consumer electronics device taking a mind-numbing 30 seconds to boot into the operating system. It should be as instantaneous as simply applying 12vdc to a starter motor despite the fact that booting an operating system is nothing like starting a car.

30 second boot time is decent. Mine takes like 90 seconds on a fresh install, stupid PA 3.0 screwed my filesystem over

First, a car & a tablet are two different things. Second, it takes my N7 OVER 30 seconds to boot. So what's the big fuss?

Rma and get another n7. Sounds like its defective

30 second boot time is normal. Mine has always booted in 30 seconds and I don't have a lot of apps on there, and the device itself is extremely quick.
It's only 30 seconds. Find something valid to complain about.
Also if your routers reception is poor, it's not the tablets fault. Mine doesn't get a good signal from my bedroom because my router is in the living room. One thing I don't do about this situation is come to XDA and complain about it. Why? Because I am not 12 years old.

Why not stop acting like an 8 year old princess. Life will be better.

Maybe your unit is defective, or maybe you should stop thinking everything is perfect, you choose.

Try changing the channel on your router, that helped me with dropped signals(just don't turn off the tablet and then you don't have to worry about the 30 seconds)

Random shutdown of my phone?

I've noticed now more than a few times my phone was off when I thought it was asleep. I'm running stock 4.2.2 unrooted. Basically I put my phone down and when I come down to it the only way I can wake it up is to hold the power button. What bug is this
? I haven't ran anything odd ? And I notice my battery gets cut by a good chunk . is this something I should get it exchanged at at the store? I just got this phone less than 2 weeks ago? I'm planning on going today but wanted your guys input before i go?

I am having the same problem, i have had my nexus 4 for about 6 months now. Last week it started shutting down and restarting randomly.
The battery dies when it reaches 20%, today it dropped from 54% to 6% after it restarted alone and lost my wallpaper.
If u find a solution let me know.

thats called "sod" sleep of death. its not actually powered off, its on but the screen doesnt wake. thats why you need to longpress the power button to reboot. it was aajor issue on the gnex until 4.2 came out. now its rare, but still happens. on the n4 too. its an android bug that was "fixed" for most.

how can we solve it?

google needs to fix it.
some people use this app as a temporary fix https://play.google.com/store/apps/details?id=com.gejos.android.wakemyandroid

thx u, i will give it a try.

So there's no point exchanging for another at the store?

Ended up exchanging at T-Mobile store as this happened again. Sorry about posting this. I searched using my comp and found a whole thread about sod.

[Q] Use n7 as home phone

I plan on using my n7 as my home phone, i will also attach a speaker to it so that it is loud enough to be heard throughout my home.
I have a question to anyone that uses their n7 heavily throughout the day, have u run into any issues by leaving your n7 powered on for more than 6-8 hours? like i said i plan on using it as my home phone, and it will be powered on for a long period of time and, it will mostly be on stand by. screen off with wifi on and talkatone in the background awaiting any important phone calls.
any positive inputs would be appreciated

I leave my n7 on all the time with the Wi-Fi and GPS radios always on and have hardly any issues.
If l realize that I have not rebooted it in several days, I'll reboot it - though I honestly don't remember ever needing to reboot it other than when messing with the recovery, or installing a kernel.
While it's setting there with the screen off with Wi-Fi and GPS on it seems to only use 1 to maybe 2 percent of the battery per hour.
