I'm planning a project to mount a tablet in the dash of my car. I'm working through all the considerations I need to take due to not being able to access anything but the front of the device. I've got workarounds for just about everything, except for that pesky power button.
Does anyone have any suggestions for bypassing it by some means? The device will be powered by the car, so it will be rare that I need to access the power button. However, removing the tablet is not an option.
Options I'm considering:
Physical rewiring of power button to a button on the dash.
Turning the screen into a power button
Wake on Lan capability to render power button useless
The physical rewire is the best option I've come up with so far, but would not be an easy task by any means. I don't know if the other two options are even feasible.
Any ideas?
Hey
Hey there...
Did you find any workaround for this? I was considering a simillar project but instantly thought the power button would be a big issue.
I know some tablets turn on when plugged, which means the tablet would turn on as you turn the car on. This happens with my Asus Transformer. It automatically turns on when I plug it into the wall socket. I'm betting this would be the best sollution. The problem is... finding a suitablet tablet that does this. lol
Cheers.

As he said receiving power from the usb adapter will (in most cases) turn on the display, that solves the first part, the next part would be preventing it to lock again, to do this go into setting/display and set screen timeout to never. Also if you are running a custom rom as cm7 you can go into tablet settings and disable the lockscreen to have direct acess into the ui.

Searched around for a few hours and I haven't been able to find a solution, so I'm turning to XDA as always.
I was using my phone earlier today, and like always, tried to "sleep" the phone by tapping the power button at the top of my phone. My screen stayed lit and for whatever reason it wouldn't sleep, so I'm trying to figure it out.
I can't deduce if it is a hardware issue or something weird with the software or ROM that I am using. I've never had this issue before, and I'm not sure how to diagnose/fix the issue.
Sliding the keyboard awakes the phone, and I am able to use the touchscreen and keyboard with full functionality, but I am not able to turn off/sleep the phone with the power button. Any and all possible help would be greatly appreciated. Thank you all so much.
does the power button work?
does the phone drift off the sleep when you set it to sleep after 1 min of inactivity?
take out your battery put it in see if u can turn the phone on with the button if u cant its broken.
Hello everyone! The problem is power button on my Asus TF. It needs to be pressed veeery hard and still it unlocks screen like only from 4th-5th attempt. That's annoying I would tell.
Is there any possiblity (tool for example) to make TF wake up from volume buttons (like in cyanogenmod 7) ?
Rooted 2.02 Prime ROM
Thx in advance for any help!
UPDATE: Just what I didn't want this issue to be, I now have a hardware power button issue. Not a software one... Guess it's RMA time!
I'm not so sure it is a hardware problem. Let me explain my situation.
My power button doesn't turn on nor turn off the tablet anymore. I cannot do a hard reset with the power problem depressed for 10-12 seconds like I used to be able to do. I'm not rooted otherwise I would use the Quick Reboot app!
I never had a hardware problem with my power button until just recently. After the 3.2.1 ASUS update it appeared that everything was fine, but a rogue app crashed the tablet (can't remember exactly which one, but I think I was installing some Equalizer/Sound apps to help with the speaker volume) and things weren't the same afterward.
I now have no way to power on the TF with the power button and need to attach the charging cable or dock for it to wake up!!!! Very annoying! I also cannot shut it off unless I let the display timeout or attach the dock and hit the lock key!
I've let it run down to 0% battery and then have had it do a (hard) restart, but that allowed the power button to turn on/of the TF for only a while. So I'm thinking it may be a software issue. Perhaps from the dock sleep fix we got from the latest ASUS 3.2.1 update?
Anyone else having issue with their power button? Would rooting help if it is a software issue?
Seems like your problem is not hardware yeah. Sorry for you, that should be rly annoying.
But mine i'm sure is hardware one ((
send it to asus for repair. i had the same problem and got it back
within 5 days. now everything is working well.
Well I did RMA the device today as the power button had become totally non-functional; I couldn't turn on/off the tablet nor could I do a shutdown (hold power button for 4+ seconds) or Hard Rest (hold down power button for 12+ seconds).
This time next week I hope to have my tablet back...
Hi,
i do own a samsung galaxy sIII aka i9300.
i have it ROMt with the paranoid ROM 1.992 (recent cm10 based ROM).
my clock/loading station is a philips AS112.
the scenario:
when i used to put my phone on my station, my phone doesnt recognize the power plug in time. the station has, for unknown reasons, a delay while generating enough supply to power my mobile phone. at least in such a low lever, my phone will not recognize the power plug directly.
i close my eyes to sleep and 1 till 2 minutes later the screen pops up, it flashes due to the recent power supply.
here is my question:
when you plugin in a power supply (whether usb or ac), is it possible to suppress the automatic screen on? i hate it and i cannot see any use while i have the s3 (with an own power led color).
my ROM has an option called dev options. maybe the solution i seek is located over there?
any hints are much appreciated
cheerioh
No dev section is not for that.
To remove that we have to tweak charging scripts but it is risky it might lead to even not charging issue...
we all should be polite enough to press thanks for anyone who helped US.
So, I need to know which Kernel or app or anything I need to take my Galaxy Tab 2 7.0 - STOCK - but rooted and make the knock knock feature work like the LG phones have. Installing this in the dash and since there is no front button, turning this on my be a pain in the rear...
Actually, I may have answered my own problem... I am installing this tablet in a custom mount and using it for my car as the main source of audio/video/nav. Since there is no home button, I originally wanted the knock knock wake function, but in researching this it seems that it works on certain kernels (that are not compatible with this device) and it also drains the heck out of the battery... So let me run this by everyone who may have input and see if it makes sense. To me, it does, but I may be underthinking the solution...
The OTG connector will be home to a hub that has one input (for power) and two outputs (for expansion). I am going to have the USB power input hooked up to the USB power in my center console, which only has power when ignition is ON. So, my thought is this. The tablet will not have power when ignition is off, but when you key on the USB will have power and thus will charge the tablet. On charge, it should WAKE, yes? The dev option for STAY AWAKE will be used to, when charging, always stay on... then the 1 minute time out option will turn the screen off shortly after ignition is off.
Make sense? Should work?
The power button of my S8+ suddenly stopped working yesterday. All was good until I forgot to charge the phone. Now it's turned off and I can't turn it back on.
Can I turn on the device without using the power button?
I think you can, put it to charge.
I really want to know did it work??
Any alarms set on your device?
If so, you can power it on while ringing alarm.
I don't think you really can turn on the device if it turn off before charging and you can't press the power button.
Let us know if you can actually do it.
If not, you will have to change the power button. There is no any other alternative.

Simply charging it didn't turn on the device. I was able to turn the device on with the power button. It suddenly worked again.
I looked online and there used to be a USB jig which forces the phone into recovery mode for older devices. Does anybody know if there's also one for s8?

Different resistor values on the pins of the charger will do certain things look into 609k resistor jigs
