I need to know if you can turn the device on without using the power button.
Can you turn the device on, just by plugging in the charger? I am going to mount one permanently in my car, and need to figure this one function out. It will not be removable, and will be flush with no access to charge port, or power buttons.
If the power is off, and the charger sends a charge to the charger, will it power on on its own?
The Iconia fits my (slightly modded) double-din space perfectly.
Thanks.
Plugging in and unplugging the charger wakes it up. If it's completely off, it doesn't turn it on, only if it's sleeping. I wouldn't suggest relying soley on this to wake it up as everytime the screen times out you'll need to unplug and plug it in, that's a big strain on it.
Ah well. I looked at a breakdown of the tablet and there is no direct access to the power button either, so I guess I'm going to give up completely on this project.
Sucks.
Can you tell me if pressing the reset button while off will turn it on? I may be able to tap into that easier if I open it up.
I have this setup in dash in my car as per my thread (link below)
http://forum.xda-developers.com/showthread.php?t=1605571
I have it so the tablet is only powered when the car is on or on the acc position , I keep the screen lock off and use a screen off app to turn it off ...then to wake it I turn the key and it comes on ...I have no problems with the tablet dying overnight .... goes down 10% at the most .....
I have asked ezterry to try to see if he can integrate touch to wake so you would simply have to touch the screen to wake it ....might or might not happen depends if he can figure it out
I would say there are other ways at maintaining power button access and still having it in dash but it depends on how your dash is shaped ....maybe fabing up a sort of slider button in your fiberglass mount or your double din dash adapter .....
Don't give up this is easily the best mod ever ......if you have any questions just hit me up on pm

I would think it wouldn't take much to mod up a simple slide or rocker button to mechanically activate the stock power button through on the dash/mount. Or even to tap into the the switch's connections. I believe it only going to be a 2 pin momentary switch.

Dash won't allow any headroom whatsoever. And it looks like any tablet I fit in there will have the same issue. Ugh. Also, I can leave the car for days without touching it, so the tablet will die often.

I looked at some diagrams and it doesn't seem to be any real access to the power button. I think because it has a light integrated, there isn't just simple switch wiring I can tap into.
I'll be glad to be wrong, I wanted the whole project to be done this afternoon. It sucks because the Iconia fits my cutout perfectly, and I've already modded my Double-Din adapter (which was only $20.)
Can you upload a pic of your adapter ?
Sent from my HTC EVO 3D X515m using XDA
Agreed.
If the tab is sitting flush in the adapter, the power switch is right there. Even a tiny notch in the mount and you could access the power button with simple lever (ie: a small straight piece of rigid plastic or metal).

Unless you never need to charge your phone while driving, it looks like you'd need to find a long power cable, which would make it complicated and awkward to use.
Slick, yes... functional, no. As the previous post pointed out - things like GPS Navigation use crazy amounts of battery power, and routing a power cable through the A pillar and under the headliner just seems stupid when a dash or window mount does the job just as well.
Most cars have some sort of power up between the visors. Usually a light. I tap into the power there for my radar detector.

Hey guys, I cracked the screen on my HOX so I replaced the screen with a unit from directfix.com
After double checking all of the flex cables I tried to power the phone on and I am getting nothing from the screen and the vibration motor is constantly buzzing.
The only signs of life is the red LED, the three capacative buttons will light up, and the aforementioned constant vibrating. If i hold the power button to attempt to turn it off the buttons blink several times then it seems to stay on after that.
Has anyone heard of a problem like this before? Its killing me not having my HOX! I had to put my sim card in my old iphone 3gs and I have to say that this sucks really bad.
Are you sure you've connected everything correctly? It sounds like there's something being shorted! I'd recommend you to dissassembly again, an assembly again BUT THIS TIME VERY CAREFUL. Best is if you use a video tutorial if you think you're not experienced enough.

Thank you for the advice. I disassembled the phone and carefully put it back together. I took care to make sure the flex cables for the LCD, vibrator/button strip, antenna, volume buttons and digitizer were all carefully connected.
Now the vibrate function seems to work fine as it just gives me a short pulse when I turn the phone on as it usually does. The screen however, still refuses to turn on. I made extra sure that its flex cable was put in the right way and that it was secured with the jaw bone connector.
This video here www youtube com/watch?v=OIeO0DueMcg&feature=youtu.be at about 6:00 shows that you can test the LCD midway through the assembly process.
I tried exactly that and the LCD would still not turn on. I am just hesitant to return it because I know that the chances of the screen being a complete dud are very slim.
Now when the phone is turned on the three capacitive buttons remain on which I know didn't used to happen.

Update: So I was thinking the phone was booting up all the way, but I just saw that my computer won't recognize the phone beyond making a connection sound; I just can't see it in windows. As i said the capacitive lights stay on, but if I fold the power button they blink 15 times exactly and the phone seems to power off. Should I assume the SoC is dead or gamble with a replacement LCD?

Hi, I'm in the exact same situation you have described above! Did you ever manage to work it out, what was the solution? Any info or help at all would be great, thanks!!
I did replace my lcd+digitizer as well as yous. And I had same problem. But it does work now.
1.open up your phone . Take all parts off, separated.
2. Take battery off.
3.Now connect power button.
4. Connect battery.
5.Switch it on (hold pwbt for 2sec), mobo+battery+power button itself.
6.Now wait 20 sec.
7.Now connect LCD ribbon(bottom one),make sure it's right in, push it in far as you can.
8.Now put it righ on bezel and connect digitizer ribbon.
9.Press pwbt and see does it work. If does put rest of stuff together and be happy.
I can make phototutorial on request.
I did it few times. The battery was touching the LCD ribbon and it comes of very little but screen comes off and I have to start all over again.
So make sure that ribbon it's not getting any pressure from battery.
Let me know does that help.

So after finally fixing all the other issues i had with my phone (broken screen, broken vibrate motor, broken speaker) i was finally at ease. It lasted for about a week with everything functioning until now the phone gods have again struck me down. This time i have what is referred to as a Power Cycle. Kind of like a boot-loop except the phone completely boots up into my homescreen then the power options menu pops up, and no matter if i click back or not, that **** is going to reboot on me. Its to a point where if i pop in the battery the phone auto boots. Here's the kicker though. If i take off the back case and just set it on the battery with an open back, it doesnt power cycle. But the power button on the case itself is not stuck as you may be thinking as i can depress it and the cover spring pushes it back. I've hard reset, even went back to complete stock (no root) and it still does it. the power button works (very sensitive) if you have no case on the back, but if that thing is on, it acts like the button is being pressed.
Any Ideas?
Sounds like the power button is stuck... Try taking the phone apart and cleaning the contacts. Then press the power button a few times to ensure it works like it is supposed to. Put everything back together, tighten the screws but don't torque them. Should not turn on after you put the battery back in, wait a few to make sure it doesn't. Then power it on and see how it goes.

still didnt work. i used some rubbing alcohol and a lint free cloth on it. the interesting thing is, when you take the case off, if you set your finger over where the button is (making no contact) it still registers that you are touching it. this is what i think is causing it to power cycle when the phone case is on, as it believes that it is being pressed when it isnt.

I had almost the exact same problem with my Epic Touch. Ended up being a bad power switch. How handy are you with a soldering iron? If you're pretty good, you can buy the switch for ~$10 and replace it yourself. (You can also try cleaning it - several tutorials here, and the "Captivate" phone seems to have the same switch and issues. Search both forums)
Several eBay sellers sell the switch you'll need.
It seems that my power button has died on my Galaxy Nexus, which is a huge pain in the strategical locations. While I know how to turn the phone off should it shut down, I have no idea how to handle anything else. I have my friends CALL ME to be able to unlock the phone and use it.
There are some apps on Android Market that specifically state that they fix power buttons, but none of them work with the latest versions of Android according to the reviews (if there's any I've missed, let me know).
I know that the phone can be turned off using a charger, since plugging it in or out makes the screen turn on. But are there other ways to turn on the screen, since it's a phone and I'm mobile most of the time?
Is there another way to remap the keys on Android? Note that I cannot root my phone, so options like that are not good either.
Is there a way to remotely turn on Android phone with a tablet through some app? Since I'm carrying my Nexus 7 with me and it uses my phones internet connection to stay online. I tried to find an app that does this, but could not find any.
Any help is much appreciated! I do not wish to buy Nexus 4 at the moment because it isn't much of an improvement and sending it back to UK for warranty seems like a huge mess that I would rather avoid for now.
Thanks!

First, try pgm (slide 2 wake).
Secondly, why can't you root the device? Once you have your screen on, you can turn on USB debugging, and use to it reboot to recovery or fastboot.
Third, there's some experience from users that fixed their own device's power button.

I had a similar problem with my Samsung Captivate a long time ago. I used WidgetLocker and enabled volume wake function. It uses volume buttons to wake the screen. I'm not sure if this feature is still available, but it's worth a try. If it is not, you can ask for a refund. There are also several apps/widgets to put the phone to sleep. I used this combo for a few months before I got a new phone. Hope this helps :fingers-crossed:
I still haven't found a solution and these apps that say they are a solution, do not work on latest versions of Android. Any other options?

I've managed to fix my power button recently, its a hardware problem. Do this only if you dont have warranty and are comfortable with opening up your Nexus.
Go to iFixit website and follow instructions to dissassemble the Nexus, its quite easy, a few screws and flat cable disconnects. Next, you need to remove your power button flex cable from the motherboard, do this by lifting the cable connector on the motherboard up and pulling it gently out.
Next thing is a bit tricky and you need to have pretty good sight and precision.
On the flex cable the button consists of 2 pieces, the flex cable and the button itself, which is like a black sticker sticked on the flex cable.
I've removed the sticker and the button that is glued to it with a scalpel (careful!!) and I've found actually rust and dirt on contacts (dunno how rust got there, i have expected dirt only), and then with my scalpel I've carefully scratched the dirt and rust of both parts of the button and its contacts on the flex cable. After that I've put the black sticker back on the flex as it was before (if it wont glue tape it with a small piece of tape) and return everything where it was and assemble Nexus back togeather. And voila! It works!
Keep in mind that I didn't have warranty so it was either open up and try to repair or toss a $200 device. Also, I'm not responsible for any damage that you do to your phone, this is just a brief description of my power button fix. Hope there will be more successful repairs :fingers-crossed:
I had to use volume_wake, while waiting for replacement power button. But this feature does not present on stock roms.
I believe i've read about remapping the hardware buttons; if you're interested, search google. I personally prefer and use smart screen on. I just wave over the proximity sensor and the screen turns on.
Try procedure described here: http://androidforums.com/samsung-galaxy-nexus/700265-power-button-not-working.html#post5797688.
I was very skeptical, but it indeed worked on my phone. Power button started to act normally again! I was amazed!

I just did this repair and I have large clumbsy fingers. thank you! I just had to remove corrosion between the button contacts and around. i dabbed nail polish remover (i'm not sure if that is a bad idea or not, but it got my phone working!) and did a little bit of scraping. on my sch-i515 there was a some clear plastic folded over the back sticker part that i had to get up, then i was able to get the black part up without having to fully remove it.
So my power button is acting up, and I think it's a hardware failure.
If the screen is on and I press the power button, the screen turns off, then back on, as if multiple key presses are being registered. If the screen is off and I press the power button, sometimes the long press power menu comes up.
I think the ribbon cable associated with the power button is failing, what do you guys think?
EDIT: just found out the power button is surface mounted to the mother board :-/ so that's a bummer if the power button is the issue.

First, and only, bump. Does anyone have any advice? I've ordered the blue plastic power button itself, but not the actual switch (I don't know how to surface mount).
I'm going to replace that. If that doesn't work, I'm not sure what else to do. Can I reflow the power switch on the motherboard somehow?
Thanks

You can get a replacement part on ebay, but it is a piece that needs to be soldered to the board. You should call local cell repair shops and see if they have the expertise to do this.
