Is there a reason why the tablet cant go into FI mode (Fixed Installation) without an OTG cable attached? I want to test out the rom but I don't have an OTG cable and I actually don't need one for my car install. I don't have any plans to usb host drives, etc.
Also, this is a stupid question but how does the ROM/tablet know that it is a OTG cable that is installed versus a regular 12v usb power source?
If I have to order the OTG cable that means I can't finish my install until it comes because I won't have access to the power button to turn it on/off. I can use tasker for the time being but would like to use the Kernel.
I have tasker set to two Events. power on and power off. If it detects any power source, it will a) turn on Wifi b) turn on GPS c) open Spotify d) Use Secure Settings plugin to make the tablet stay awake. If it detects no power, it will do the opposite and turn wifi/GPS off, kill Spotify and turn the display off in 7 seconds. This will work when I turn on/off the ignition.
I have a question though.. How can I get it to go to Deep Sleep using tasker? I understand Timur's USBrom's FI mode will make the tablet go into deep sleep when you disconnect power source. Mine is just killing GPS/WIFI/Display. Would turning the CPU clock down and killing most apps and alarm/wake features be essentially the same as deep sleep?

I've got a Universal with all the default ROMs and whatnot. I plug it into my PC overnight to charge. I have it set so that the backlight turns off after 5 minutes when connected to external power, and it normally does so. However, it seems like it turns itself on again at random points (it does turn itself off again). I cannot discern what it is that is causing it to turn on, the only relevant thing I have running is ActiveSync and it isn't busy syncing.
Has anyone got a clue why it might do this?
mine will switch on when it's downloading e-mails.
ActiveSync wakes the PDA up at regular intervals to see if it needs to sync, its something you have to live with.
in power settings, the default is to turn on while being charged
have alook at power management in settings
For an unkouwn reason my device wont't go sleep when I push the power buton. also after some time of connection (3-4 minutes) the screen goes blank and don't respont until I plug the power or a usb cable connected with the computer.
To use it I need a soft. that force the hermes go to sleep.
Do you know any?
Thanks
Is anybody can explain to me , how the standby mode works in X1.
I just changed from an asus p535 where if i pushed the power button once the phone gone to sleep mode and the active sinc lost connection, the phone completly in sleep ...
Now with the x1 when i push the power button its not gone to sleep and the AS just keeps working, and because of this i worried about the battery life, it should work for longer time when its completly in sleep
How can i archieve the full sleep on X1?
I think it makes a difference if USB is connected or not. Power button works different with Headphones plugged in (Screen off) or not (Suspend).
When you sync your phone with your PC using the USB cable, the battery is charging as if it was through the wall charger
WM is set by default to "not turn off the phone if not used" when it used on external power so it never go to sleep mode
If you want your phone going to sleep mode when used on external power: go to settings -> system -> power. Then check "turn off the phone if not used for" under "on external power" and set the time it should wait before going to sleep mode
plus it's a myth that charing it often is bad for the batt so it don't matter if it's charging when you have it connected long periods of time

Hello! I am running cyanogenmod and Timur Rom on 2012 N7. I have tasker to detect power on and power off but here's my trouble..
The N7 will only detect power when the display is on!?!?!?!
If the display is turned off or times out or is locked and I give it power, the display doesnt turn back on automatically. I turn it on manually with the lock button on the side and the battery shows no charge coming through.
With the display still on, i unplug and plug the power back in and it works fine!
I tested it on the PC. PC detects the N7 fine and sees the HDD. Even with the display off, the PC will detect the N7 and I can explore folders but the N7 still receives no power until I manually turn the screen on and unplug and plug the charger back in!
This is preventing me from doing the car dash install because I cannot depend on the N7 to turn on display automatically because it does not detect power with screen off. Only with screen on!
I have went through all settings a million times, tried every 101 troubleshooting step, and I cannot figure it out.
Please, please, please help me figure this out. It's driving me crazy! :cyclops:
I made a car dock for my Nexus 7 (2012, running SlimKat ROM, on Lollipop).
It works great, except that if I don't drive for 2 or 3 days the battery runs down to zero while it's sleeping.
Is there an app that will shut the tablet down (completely) when the charging current goes away (when the car turns off)?
I tried "Autosleeper", which claims to do it, but even if you set "power off" it only puts the tablet into sleep mode (at least on Lollipop).
Alternatively, is there a way to really minimize the power draw in sleep mode automatically (turn off all radios, timers, apps, etc. until it's woken up by power coming back to the USB port)?
** solved **
OK, I figured it out.
Autosleeper works fine (shuts down the tablet) if the tablet is rooted. Not otherwise.
** NOT solved **
I spoke too soon.
It works ONCE. If you boot the tablet, set Autosleeper to power off on loss of USB power, it'll do it once (and prompt for permission to root).
Even if you say "permission granted always", after it reboots it goes back to just sleeping, not power off.
