Something really strange happened

Last night before bed, I turned off my kindle as I always do if not charging. This morning when it turned on, it had restored a backup of my original kindle OS from when I first got it and rooted and installed twrp. Did this all by itself and has never done this before. Do I have a ghost in my kindle? I was able to use twrp to restore my old backup of aokp before any amazon updates rolled thru and broke my root. Anyone ever had anything like this happen? Unfortunately I can't not turn off my kindle to make sure it doesn't happen again as it the only way I can get it to charge is to turn it off and plug in the charger while its off. Dont know what's up with that with aokp, but works for me.

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.

I'v got the same problem. So +1. Any ideas?

I have the same problem, i am actually talking with the Asus Support Centre

I emailed them. All I can do.

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.

With every electronic gadget using Lithium-ion batteries nowadays, it doesn't really matter how/when you charge it.
Some would argue to make sure to allow a full discharge from a full charge from a battery calibration point of view, so the battery meter is more accurate. It wouldn't affect the health of the battery itself either way.
Things like memory effect doesn't apply to lithium-ion. How often you charge it and how much you charge it (full or partial charge etc.) doesn't affect it much either. The only 2 things that can potential kill a lithium-ion is high temperature and letting it discharge far too low to the point that it cannot be charged up again. Note that all electronic devices will power off way before it even reaches this threshold.

Read this in a different thread when i was unboxing my nexus 7, i let mine sit for a while on the charger before i turned it on, but it came charged already. So far i have not let my nexus drain to 0% and the battery life on it is great, it can go for a entire day.

I too just got one. May be came out of the box with 4.2. After I signed in I checked for an update manually, and it immediately upgraded to 4.2.1. I then rooted immediately! Battery has been impressive so far.

Sounds like it may be a corrupt download. Unless you plan to remain on the stock ROM just unlock/root it and then install what ever ROM you like.

[SOLVED] Strange Screen When Booting

I have a case on my Nexus 7 that uses the four sensors on the side to turn the screen on and off. I was using the tablet just fine, then I close the case like normal, and upon opening it, it would not turn on. The only way to get a response from the device is by plugging it in and the screen just lights up black. Any type of power reset using the button combinations result in the screen shown in the video at the end of the post.

Sorry I can't post the link. I don't have 10 posts yet.
Solution: I removed the back cover and disconnected and reconnected the battery.

100% stock. It never did anything of the sort. I didn't get the 4.2.2 update until around Wednesday of last week and it happened on Friday

Not that I can recall. The tablet is purely my Portable Netflix/Evernote slave. I've left it on the wall charger for 24 hours, and on a usb port charger for 24 hours, to see if that helps but that won't do anything.

If you don't have anything important saved, you might to just try and wipe everything and start fresh. Are you rooted?

I have nothing that I would need to save, and how would I accomplish the wipe? I've never done it with an ASUS device before.

Re: Strange Screen When Booting
Check the stickies in the dev section, they will show you how to root/unroot and flash back to stock. You can likely just use the updated nexus 7 toolkit.

All of the options are saying it needs to be in ADB or in Android. I can't get it to show any of those screens to verify I'm in that mode.

I got it fixed. I ended up just removing the back and disconnecting the battery to force a power off. Thanks for your help though that tool will come in handy later

Good deal!
There have been a couple threads where folks reported similarly-behaving screens. "sparkles", "static", "like an old tv screen", et cetera. I think at least several of them were similarly traced to battery charge issues or loose terminals on the battery connector.
Maybe add "[SOLVED]" to your thread title and it will help future visitors with the same issue.
cheers

Leave it charging for a good couple hours. It sounds like you really run it dry. And when in bootloader... You can literally run it dry. Always charge around 5% I would say.

A lot of people are having a problem with the battery wire. Kind of a longshot , but if you open it up, the cord to the battery might be loose. I would look it up a bit more but a ton of users are having that issue.
