Hi all
When I have my Trinity in my active car kit, the power lockout (set at 15 mins) kicks in. I want this when the phone is on battery but not when on mains / car power. Having the device lock means having to unlock it to respond to any voice calls, etc.
Anybody know how / if you can tweak to give;
battery - 15 lock require PIN entry
powered - no lock
TIA

I have this sitting on my HD, I know it has worked for me in the past but I haven't used it in a while.
Thanks - will give it a go tomorrow (err, later today).

Tried but apart from saying that it was written for a different version of Windows, didn't actually do anything,
However, may have found an alternative in the forums - http://forum.xda-developers.com/showthread.php?t=259368&page=2 post number 17.
Just changed so will see what happens.

hi all,
i think i need help from you guys.
i am working to install our tab as stereo car. it work very well !!!!!!!
my question is, there is a way to power on the device without use power button? i plan to connect it to my notebook.
this, for me, make big difference in making the mould for the car dashboard.
thanks indeed and happy new year!!!

If you want to take the case apart you could remove the power button and wire in a short throw solenoid that is activated by the car's internal 12 volt power. This would trigger the tablet's power button automatically when the car started.
You'd need to root the device to install a power off button on the homescreen through so you could power it off via the touch screen.

thanks man,
about root and install power off button i already done it, no problem, and i am working with "smart screen on" and "off ".
about your suggestion, i am not sure if i am able to follow your idea with my poor knowledge. i will appreciate if you can give me a little step by step guide.
eventually.... let's say that i dont want to remove the power button..........
if the device for some reasons will shut down (not just the screen, i mean total power off) is there a way via pc to power on again without use the power button?
maybe adb command or other way?
thanks again to all, i have almost finish all the work so that i am ready to assebly it on the car.......
cheers
Well you can't use adb to power on the device. That deffinately doesn't work.
What I was talking about was using a solenoid that runs on 12 volt power. Basicly a solenoid lets one electrical circuit influence another electrical circuit without the two circuits connecting.
The car's DC power would activate the solenoid which is basicaly just an electromagnet. When it has power the electromagnet activates and a little piston inside it completes an electrical connection for the circuit you want to power.

Even easier to wire, you could also move the power button. Just take out the one that's in the tablet and run two wires from the existing leads to another power button that you remote mount somewhere else. This won't be automated to start when the car does, but it will let you use a remote mounted button that functions exactly like the existing power button.
The only down side is the difficulting in installing those lead wires. The power button in the tablet is wired with a VERY TINY ribbon cable. It's basicly two copper lines embedded in a single flat plastic wire. It's very delicate work to cut those and soilder in new wires. It can be done, but it takes a delicate hand with surgical precision.
If you do it right though, it will work like a bloody charm. And you can put a power button on your dashboard somewhere that's easily accessible.
The 3rd option, that's the least high tech, is to fabricate something that lets you press the existing power button. Perhaps a hole in the dash bezzel that surrounds the tablet that lets you stick a finger in under it and hit the button. That's guarenteed to work. It just involves careful fabrication to make it look nice.
Also, for the application you're trying to use the tablet for, read through this message board....

It's a message board dedicated to in car computers. I built a Windows 2000 based PC to run GPS and audio in my car and that forum was absolutely invaluable. If there's another sollution to remote mounting smartphone power buttons it will be there with how to guides. It's a great community for getting help doing the kind of project you are working on. They will probably have good software ideas for you too to get the best use out of the tablet for your purposes.

you are really the man,
thanks indeed cause u spend time to help me, i already found some quite good stuff, but i'am not satisfy.
i will follow your suggestion, i will learn more and i will let you know about.
thanks a million again and keep in touch
cheers, happy new year!!!!!
I have one in my dodge magnum. If your looking to have your tablet turn on with the ignition you can try a program called tasker.
I have power supply attached to my ignition and when I turn on engine my tablet wakes up. I have a ton of things automatically start when it recieves power. Everything pauses when it doesnt recieve power.
Or you could also try tablet talk and maybe those nfc sticker things. You have a lot of options of you dont want to open up the tab.

thanks for your help too
but i think you are talking about to wake up tablet, right?
my question was about to power ON the device without to press power button, not just wake up. about this i have already manage it with smart screen on/off from the play store...........
cheers

Did you get that app working well? I couldn't make it work at all.
The whole idea sounded neat even though Im not doing a car install.

hi man,
yes, i have installed smart screen off (that can also wake up the device) and it work very well.
i am using two wave to let the screen off and two wave to wake up. all other setting as default.
Smart Screen Off 2.0
let me know if i can help you in some way.
cheers
I second the Tasker solution. Also, since you're mounting in the car anyway, i would look at an app called Torque. A cheap bluetooth OBD2 interface can be used, and Torque can be set to put the device in standby when ignition is turned off or when tab isnt "plugged in" (because power to tab is switched by ignition).
Using Tasker, you can wake the device when the ignition is on, then start the apps you use while driving (pandora, maps, nav, my tracks, etc). There's a bit of a learning curve with Tasker, but spend a bit of time with it, and you will start to see its potential!
Yes. Tasker is a great app. I use that in my og galaxy tab I have installed in my car. I wouldn't worry about powering the device on and off. If your trying to save power, you won't lose much even on really hot or cold days. Tasker has a lot of options that you can set to help save power.

Hi guys, this probably isn't specific to my tablet model.
I recently had issues with my tablet, Ampe A10 Quadcore; it was always showing that it was charging, even when unplugged. It eventually died completely but could also be charged via USB so it is not the end of the world. I'll keep it brief...
Basically, I have removed the inlet thingy, for the direct power, from the mainboard and it still says that it is charging. Have a look at the attachment and, if you can, please tell me what I need to do to get the unit to be in the state of 'discharging'.
I had a look at the thing that came off and I believe that (with my limited knowledge) 3 is ground, it had a pin going down the middle of the inlet; 2 and 4 are a gate (from the looks of what I pulled off) that detects when something is inserted, it must also take the - or +; and then 1 and 5 takes the other - or + and it just a solid connection that picks up the electricity on contact.
I need to know how to make a change so that it makes the status discharging and also what the best way of doing this is.
Thanks!
Also open for any questions.
Hello Gentelmen,
I am rather new to android dev but seassoned in linux, i decided to convert my old phone (samsung admire) into an in dash computer.
I am using two basic applications:
* Torque OBD2 Connector: This connects to the car's OBD2 Port, reads the computer and displays information on screen (like HP, Torque, Manifold Pressure and temp, Boost ...... )
* Autoguard Blackbox: This app acts as a CCTV recorder taping my driving and saves it in case of accident so i can have video evidence.
I have modified the andoid system to open both applications on boot and on external power and to kill them when external power has been disconected. Also when external power is disconected phone will wait 5 minutes then go to sleep. (yes i realize there are apps for that but i like shellscript)
This means that when the key is turned and the car is on recording automatically begins and my gauges come up, when the car is off they close AND STOP RECORDING and go away without any kind of interaction on my part.
The problem: Whenever the car turns back on, external power is connected and i would like to have the phone do a full boot so that my scripts kick in,however instead it goes into charge only mode where it boots in to some kind of "hybernation state" that only displays the battery charge in the middle of the screen.
I would like to bypass this and have the phone do a full boot whenever the power is connected.
I have searched for weeks and have found nothing but people withthe same problem and solutions that involve harware and wiring and soidering however this is not an option for me because the phoen is exposed (not actualy insidethe dashboard)
I am not afraid to compile a custom rom and have it run on the phone ... the phoen is solely for the propose of having the dashboard display. (i dont use it for calling)
Could you guys point me in the right direction?
Thanks in advance.

Problem:
Solar powered Remote cameras,
Mesh network projects,
Time-lapse projects,
^ just some projects needing a reliable phone
Idea for solution, but how to Implement?
- power cycle the phone at set intervals. Then if the phone has crashed then at least it will become available again without having
- pulling the power from the battery isn't too hard, especially with a removable battery... But...
-pressing the power button is more difficult
So:
- can we alter the boot animation to force into a normal boot up procedure after a set period of time? This action alone would allow greater automation
Where can I find more info on this? My guess would be non Chinese Google / Samsung / nexus phones would be a better choice for cheap phones to try this in as they are better documented
