Automatic Wakeup on plug or unplug - Acer Iconia Tab A100

The A100 wakes automatically from sleep whenever it is either plugged-in or unplugged from its charger.
I would like to disable this silly behaviour if possible.
My wife learned the hard way. Prior to leaving on an overnight trip, she plugged in her tablet with its folio case closed. When the power button changed from orange to blue, she unplugged her tablet and threw it into her purse, not realizing it was awake all the time. When, several hours later she took out her A100 to use it, it was dead.
What would it take to disable the auto-wakeup? Is there a config file that could be hacked by the root user? Or would it take a complete new firmware?

In this thread http://forum.xda-developers.com/showthread.php?t=1288306, they're discussing the same issue but with the A500, still it could be of help.
Ok, I'm having the same issue and I tried almost everything possible except rooting and using a different rom (I just don't want to). But, I found a work around at least for the the screen to stay off by installing Wake Lock - PowerManager. Now, the device won't go into sleep and the cpu will be on all the time.
I installed the app in my A100 and selected the first option, then pressed the power button and the screen stayed off during all night until I turned it on again by pressing the power button again. Of course the battery was on 25% from its aprox 86% I left it before me going to bed, at least 9 hours passed when I waked up on the morning and turned the screen on.
Then I charged the device completely and started to listen to music with my Koss UR40(I mention which headphone as a consumption variable) and activated the app, turned off the screen and aprox 1 hours later only 10% of battery was consumed.
Notes:
Music app I used: Folder Player
Airplane Mode: ON
Hope the info is of any help!

Try tasker app to cofigure the behavior of a100 when you plug it out.

[Q] Stock HOX - bricked by skype?

My phone is totally non-responsive. Pressing the power button is non-responsive, plugging it in to charge does not seem to work; no red charging LED. Won't boot while plugged in.
Here's what happened:
I set two alarms for this morning. One to wake up for a skype call I was supposed to make, and a second to actually get up. I hit snooze when the first alarm went off. I had about 50% battery according to the battery icon in the top right. I decided to make the call anyway and launched skype and started a video call. During the call the alarm went off again and I dismissed it. The video was frozen on the frame when the alarm went off. I backed out of the video on the skype app, and went back to it. The video was now black, and the phone warned me the camera was off. The camera icon in skype showed it was on, but i pressed it anyway, at which point the icon changed to the no-video icon. I selected front camera, the icon remained showing a camera with a red line through it. I still did not have video, my calling partner could not see me anymore either. We finished the call with audio only, about 15 minute total phone time. I pressed the top hardware button to shut off the screen and I went back to sleep waiting for the next alarm. That never came. I woke up and tried to turn on the screen with the hardware button and nothing happened. I believe I saw it flash a green LED notification as I was doing this too, but it never flashed again. I thought maybe I left skype open and the battery died, so I plugged it in. The phone won't start charging, or at least the LED wont show. I tried booting it after it was plugged in five minutes (still no LED) and nothing happens.
I unplugged it and tried holding power and down volume for 30 seconds, then I tried power and up volume, then I tried power and both down and up volume all for more than 30 seconds. No response. (what is the proper hard reset for this phone anyway?) I have since left in unplugged hoping that the battery will completely drain and then I can start using it.
Any ideas in the meantime? this phone will last a week with 50% without using the screen or the processor.

Does your hardware capacitive buttons flash when you press the power button for 10 secs?

No, nothing. I have a fully appreciation for the term "bricked" right now.
I think going back to the store is your best option in this case .... Unfortunately
yea, I think so too. I already emailed customer support.
If you plug the phone into a computer, go to device manager. Does it say QHSUSB_DLOAD anywhere?

So I went out all day and left my phone at home (the shop i bought the phone is on the ground floor of my office building an hour away, I was going to wait till monday to have it looked at there). Got back and plugged it in, was about to try usaff22's suggestion, but the LED started flashing red. after a bit it went solid and the phone turned right on. still no word from HTC, but it is the weekend and all. Maybe Jellybean will fix the root of the problem. Anyway, thanks for the suggestions everyone!

[FIXED] STOCK HTC ONE - Screen not turning on, phone running hot, battery draining...

Hey guys... so I've noticed my phone acting a bit funky after the latest KitKat update. Just a bit of freezing and lagging, but my 32GB of space was also full. So I did a complete wipe and factory reset and started from scratch. At first everything was great (about a week or two). Then the past day or two I've noticed the below issues...
1. While at work, I keep the phone plugged into my computer via USB with Internet Pass-Through and WiFi turned on. I have it setup this way so I can use the computers internet and trickle charge the phone at the same time. But when I leave my desk I simply unplug my phone and it connects to my works WiFi while I'm walking around the office. I get back to my desk I plug it back in.
Problem: I've noticed lately that I'll pick up my phone and it's HOT to the touch. As well as the battery percentage is actually dropping even though it's plugged in.
2. At night when I go to sleep, using the HTC Charger and Cable that came with the phone I'll plug it in next to my bedside and let it charge.
Problem: I'll wake up in the morning, hit the power button to light up the screen and nothing happens. The Home Key and the Back Arrow (are these what everyone refers to as the "soft keys"?) are lit up but the screen will not turn on. To get the screen on, I have to HOLD the power button down, the screen then lights up with the Restart menu showing (and yes I've restarted it many times in hopes of fixing this issue) and I have to tap outside that box (on my wallpaper or wherever) and the menu will go away and my screen is back up like normal. However as soon as I tap the power button to turn off the screen (not the phone) and tap the power button again, nothing happens except the bottom keys being lit up. It's an ugly circle.
I have noticed a few times when holding the power button to bring up the screen/reset menu, sometimes the screen/reset menu will not turn on, but the home and back arrow keys on the bottom will flash a few times.
Any ideas guys? Loved this phone up until now
So after 200+ views and no comments I'd just like to add that I think I found the fix for this. I spoke with a few different HTC techs and tried multiple things before having to ship it out to them and right before doing so they had me reset what they termed the "Charging Logic"
To reset the Charging Logic
1. Power phone completely off
2. Once powered off, hold the Volume UP, Volume Down, and Power buttons for 2 minutes (my fingertips were sore afterwards LOL)
3. You should get a white background with the green HTC logo turn on/off multiple times. Almost as if it's trying to reboot...
4. After 2 minutes, let go of the buttons and let it reboot.
DONE!
Since I've done this, I've noticed my battery life extremely improved. My phone is no longer getting crazy hot, and the screen now turns on after an over-night charge!
Hope this helps others!
Does it matter what kind of charge you have on the battery when you do this? This is the first I've ever heard of resetting Charging Logic.

I'm not sure what you are asking by "what kind of charge". Could you clarify?

Does it matter what percentage your battery is at and does it work for rooted phones? Do I need to be on the stock Rom/recovery for it to work?

Sorry I'm not familiar enough with the developer side of things to tell you "it's ok" or "not".
What I can say is, the HTC tech never did ask me if my phone was fully charged or what percentage it was at. Which at the time was like 97% if I recall correctly. I am completely stock...
I would imagine this would work for rooted phones and it wouldn't matter what battery percentage but can't guarantee you...
I just wanted to come back in here and update this again. The above fix did not actually fix the phone as the problem came back again eventually. I am now on my third HTC ONE M7 and looks like I'll have to send this one back as well for the same issue.
I have a theory that it's either a problem with the OS or Light Sensor causing the screen not to turn on.
Can a mod take this thread off "fixed"

Phone not turning on.

Hi. So after a long wait I got my Zenfone 2 ZE551ML today. The first thing I did was turning it on and it turned on normally, then I proceeded to make the initial setup (logging into google account, etc) without any problems. Then after about 10 minutes of use the phone suddenly turned off with the battery being at around 35% and didn't want to turn on again. I read that old firmware (like the one that comes default with the phone) had battery display errors so I thought the phone had run out of battery, so I charged it for 8 full hours and I unplugged it now. To my surprise the phone is not turning on either. The only way I can make the screen show something is by connecting it to the charger, it vibrates and displays a white battery icon, eventually changing to fully green (fully charged battery, the green led indicator also appears) only to disappear like 3 seconds after. Can't turn the phone on while charged and can't even make the phone show the battery icon again (unless I unplug and plug again, repeating the cycle). So, what can I do to turn it on?
Thanks in advance.

I have a feeling that you did not hold the power button long enough. Disconnect the charger first, and wait for about 10 seconds. Then, hold the power button for at least 6 seconds. The phone should then vibrate and then you may release the power button. Other reasons why your phone may not seem to be turning on at all might be due to the back cover not being fully locked in, thus not making any contact with the power on the motherboard itself.
Do report back the results.

I did. Doesn't work. I also removed the back cover and pressed the power button with nails with no results either. Personally I think there's something to do with the power button as it doesn't even responds while charging (pressing it should display the battery icon) and the only time I could use the phone it didn't work to wake up the phone or setting it to sleep, only double tapping worked. What is strange is that it worked the first time I turned on the phone though.
Are you able to get into FastBoot mode? If so please try performing a hardware reset including wipe cache partition. Please see the following:

Stock Tab S 10.5 won't turn on, then stuck on logo screen

I just received a used Tab S 10.5 from a reputable Ebay supplier. It didn't turn on initially so I plugged in the charger and it showed a solid gray battery icon with a solid white lightning bolt. I assume that means it's fully charged. Still wouldn't turn on with the power button so I tried holding the power and volume buttons together. I'd get a short vibration after 6 or 7 seconds and the battery icon would go off but it wouldn't start. I finally got it to start (not sure what I did differently) but now it has been stuck on the Samsung Tab S opening screen for several minutes. I tried turning it off with the power button but holding it down for about 10 seconds had no effect so I let it go and the logo screen stayed on.
Before I contact the supplier for a refund or exchange I would like to know a few things. Are the Samsung Galaxy Tabs finicky about turning on? Any known issues with power buttons? What's the proper procedure with the power button alone doesn't work? I've seen both power + volume down and power + volume up.
Update 30 min after original post: my assumption about the battery icon was incorrect. I tried turning it on again it worked and the battery showed 3%. I started the setup but just connecting to my network drained the battery down to 0% (even though it's plugged into the charger) so it shut off. At least I know now I'll have to wait a few hours.

Since the issue has been resolved (and was due to inadequate information on my part rather than a problem with the tablet), I am asking the moderator to remove this thread.

Is there a setting to keep Tab S from shutting off while plugged into wall charger?

I guess the tablet isn't actually powering down, it's just going into sleep mode, or whatever it's called when the screen shuts off. Anyway, is there a way to keep this from happening when the tablet is plugged into the wall charger? It isn't a major deal but it is sort of annoying when I have something large downloading or have the tablet otherwise doing something on its own, but I'm not actively using it. I like to walk by occasionally and check in on things, but will often find that the tablet has shut off. Then I have to turn it back on, swipe the screen, or login if I have security on. Anyway, it would be much nicer if it would just stay on when plugged in. I've looked through the settings and can't seem to find anything related. If it's there, I'm missing it.
Thanks.
There are different between shut off and standby (sleep mode):
1- Shut off: Your tablet is shutdown, the only way to turn it on is power button.
2- Standby: the screen is off, you just need to press power or home button to turn the screen on in 2 seconds. In order to prevent the screen turn off so quickly, you only need to change the screen timeout to 10 or 30 minutes. If it turns off by itself, your tablet has a problem.
Mine can standby a whole week and it only loses a little charge when waking up.

There is no 30 minute screen timeout on my Galaxy Tab S 10.5. The most I can set it to is 10 minutes, and that's where it's at.
Thanks anyway.

we call that a screen time out... you can activate the stay awake while charging feature in developer option... how to activate developer option.... go to setting -> about device -> and press the Build Number 7 times. you will see something like developer option activate. then find the stay awake while charging option. that's all. :victory:

Super, that's exactly what I was hoping for...

I'm starting another thread.
Thanks!
