How to power-off (for real)

I just received my DHD and as soon as I inserted the battery, it powered on by itself. I plugged in mains for a long charge cycle (I don't want to use it while charging).
I want to power off for real but it seems that when I press the power button even for prolonged time, it just goes to standby. I want to charge it while powered-off. How do I do this?
I didn't have the chance to play with Android before so here I am asking easy questions I guess.

Try with this:
Tap the power button on the upper side of phone for few seconds, then you will see on the screen new window with three possibilities - power off, aeroplane mode and restart. Choose power off. Then you can charge your phone.
Other possibility - work/play with your phone till the battery is fully drained and the phone will switch off itself.
Hope this helps.
Regards.

go to settings applications and disable fast boot

Thank you all. That's what I was doing but I guess that the screen was locked and it didn't work. As soon as I unlocked the screen and performed this procedre it worked. I just didn't want to start working with the phone until it is fully charged and that's why I was trying to switch off without entering the phone.

If you don't disable HTC Fastboot you phone isn't really off, just hibernating.

Good point but I had to go through all setup steps until I am able to configure this setting. Anyway, I was planning to leave the phone charging untouched for several hours but I guess that wouldn't be possible.

My phone boots back into clockwork recovery even when fastboot is disabled.

Apparently the DHD uses the recovery to display the charging LED (orange or green), so when you replace the recovery with CWM attaching the charger when the phone is off will start CWM.

[XOOM 2] Charging LED and odd power behaviour...*UPDATE*

Gents,
I have just got a Xoom 2 16GB Wi-Fi only model and seem to be having a problem.
I have read the original Xoom tips & tricks thread and searched but want to clarify a few things...
On the Xoom2
1. The charging LED does not light. Apparently it only lights when the unit is powered off. Ok, I can accept that.
2. When plugged in, if I try to power my unit off it powers up again on its own.
I spoke to Motorola tech-support about this and they said that was "designed" behaviour. The unit will automatically power on when the charge level is above a certain threshold.
Is the above true? Does the unit have to be VERY low on battery before the LED will indicate that charging is taking place?
I'm rather confused as all of the above seems totally counter intuitive to me.
Any advice appreciated.

Yes you cannot charge the tablet while it is powered off, it will automatically turn on and charge.
Apparently they changed this in the latest software update but I have yet to test this out.

The behavior will change when you get the 3.2.2 update. There's a powered off charging mode for quick charging now.

Xoom 2 charging
Yes, my xoom 2 also turns on to charge! found this weird but it must be the case.

Hrm.
Ok so I've done more digging and it does say on the Moto website that the "on to charge" behaviour is normal.
I am keep to get mine updated to 3.2.2 however my "System Updates" option just tells me that my system is up to date despite being only 3.2
Furthermore, I had trouble powering my device up again. I had what seemed like problems straight out of the box but after speaking to tech support they told me to charge the unit for a while (like a few hours) and then give it a go.
I did this and still no joy. I called again and they asked me to try pushing and holding all three buttons (i.e. vol up, vol down and power) together for 15s.
After I did this the unit powered up, I managed to get through the setup procedures and have a little play.
Then I put the unit in my bag and left for home. I got home and the unit wouldn't power up. So I tried the reset and got presented with a funny menu (looked like a bootloader to me).
Not sure what I selected here but it booted albeit with some weird apps showing.
I rebooted again and now it seems fine but not sure it's actually charging!!!
I might have to send this unit back for a fresh one.

Ok,
I've narrowed down my problem. If the unit is plugged into the wall adapter it will charge and work as normal. If it enters standby mode the unit will power on when the power button is pressed
Great.
However, if the unit IS NOT plugged in and it enters standby the power button WILL NOT turn the screen back on. It will just sit there lifeless.
The only way to recover from this state is to "reboot" it by pressing and holding the 3b buttons (vol up, vol down and power) for something like 10-15 seconds until the bootloader menu is shown.
Here's the real kicker though, if the unit is on but SHUTDOWN using the power button pressing the power button subsequently WILL turn the unit back on (i.e. it will go through the boot process showing the Moto logo/circles animation).
But again, once powered on, if the unit enters standby the power button will not turn the screen back on.
What is going on here? Does it just sound like my unit is faulty and needs to be replaced?
Any help appreciated...

Bump.
Anyone got ideas/suggestions regarding the power button/standby issue I am describing above???

have you fully charged it yet?

Yup.
I charged it for a good 8 hours + (overnight) and it still exhibited the same behaviour.
I think the power button is dodgy/intermittent and that is what is causing the issue.
Either way, I've RMAed the unit back to Expansys and am awaiting a replacement.

New unit - Battery Drain. Please help

HelloAll,
Ive had my new head unit installed for two days now, and been through all the settings etc checked all the leads and cant see anything wrong, but have had to put my car battery on charge twice now.
It seems the head unit drains the battery when I turn the car ignition off.
Also I have an airbag fault, but I thought this was just due to me unpluging the passenger side airbag warning light when I was fitting the unit.
its a Erisin ES3015V 8" VW Android 5.1
The only thing I left unpluged was the old GPS antenna as not needed (would this cause a drain if touching something, forgot to tape it up)
Also due to the instructions being in pigeon english can any one advise how I should set the dip switches on the back.
see pics attached.
Many kind regards
Guy

You may have swapped B+ and ACC. Normally B+ is yellow and carries +12 continuously. While ACC is normally red and should only carry +12 when your key is in ACC or further.
Concerning Airbag-light. Some cars need an airbag-light reset through the OBD-bus or manufacturer-bus. Sometimes it's good enough to disconnect the battery for some hours to clear various lights. I doubt that in your case since your battery been drained already. Maybe not low enough to clear the OB-computer.

thank you for the reply.
I might have sorted the power drain, flipping dip switch no 3 to off has now enabled the unit to shut down fully when the keys are removed from ignition, and now the standby option works so i can takekeys out and then have unit in instant on mode for 30 secs, 2 mins up to 2 hours etc before it completly shuts down.
I was thinking the light just needs a reset ill go see my friend who has a vag box to reset the light
Thank You

Similar problem
Hello,
Sorry to bring this back up...
I have a similar situation, but my unit Eonon GA6157f is installed in an Audi a3 with a BOSE unit.

Does anyone else have any ideas of how to solve this?
I get a dead battery after 24 to 36 hours
thanks

Hello.
I have same problem with Audi A3 with Bose. Any solution?

Xtrons TR771L fast boot rarely working

I installed one of these units in my Alfa 147 yesterday and am having a problem where it will boot from completely off most of the time. Occasionally it will boot from standby in around 3 seconds, but most of the time i have to sit through the entire boot from cold sequence.
I definitely have my ignition and constant wires the right way around, and I don't think it's a battery issue. I tested the voltage of the constant 12V and it only dipped to 10 or 11V when starting the engine. The problem also arises when just turning the key to the second position which rules out the starter motor bringing the voltage too low.
Any suggestions on how to fix this would be much appreciated.
Side note: the surround/bezel which came with the cage (from xtrons) doesn't fit over the head unit. Anyone else have this problem? It's pretty ugly having the cage exposed.

I have the same unit and I just installed it. I tried connecting by either switching A4 and A7 (my car is Peugeot 107 and this is how it should be, similar to your Alfa I believe), and without switching them, and it's the same. Also, I set the timeout on powering off when ACC is off to 10 minutes, but my head unit turns off immediately.

I've since figured out that in my case i was just expecting too much of it. I thought that it would stay in standby indefinitely as long as it had a power source. Turns out it will only stay in standby for as long as you set the ACC off timeout for, which is 1 hour maximum. I think this must be because it consumes too much power even in standby and would drain your car battery over night.
The way mine behaves now is that if i turn the ignition off it will go in to standby for one hour. During this hour it will turn back on within a couple of seconds when the ignition is turned back on. After that hour, it will need to boot from cold. This isn't actually too bad as it usually takes less than 10 seconds for a cold boot.
My main gripe with this unit now is how much the screen is recessed behind the bezel. Due to the angle it's at in my car this means that the bezel obstructs half of the notification bar when i'm sat in my natural driving position.

Actually, it turns out it works OK for me as well. I dropped the adapter that switches A4 and A7, and it works fine. It has it's flaws (today being a really sunny day, I wished display was a bit brighter), but it's a nice upgrade on my 2008 car stereo.

I know what you mean about the brightness. It's just about usable on a bright day though so not a deal breaker.
I can recommend the DVR019 dash cam if you don't have one by the way. Super cheap and easy to install - just requires USB connection to the head unit.
Let me know if you figure out anything useful about this unit.

Are you guys happy with the sound quality? I am looking into buying same unit.
Did you buy any special harness to connect to the car?

Set timeout to autosleep instead of timed, that way it'll always boot in seconds, mine starts instantly even two days later

Can you explain how to do that? I only have the option for 10 minutes, 30 minutes and 1 hr and it doesn't work on any

Xtrons Androind installing
Hi!
Did you get any answer or solutions to this, after all..? I have the same problem, and originally installed the car navigator to get powered from the ACC cable.
I didnt try this yet, but i bet to use the 10min / 30min / 1 hour switch off, the navigator should be wired to the yellow 12V cable to get continuos electricity, and not to the ACC cable, what gives eletricity ONLY when you turn on the car..
Of course without the turn off timer, it would drane out the whole battery.. I think 30min delay would be pretty cool, the time to go for examle to a store and come back, and find the android system still fast and rdy to go..

ATOTO S8 power issues

I picked this head unit up and it works well when it works. It will work fine one day and then the next time I get in the truck it won't power on. I've found that if I pull the unit out, unplug the wiring harness and plug it back in it comes back to life. Last time I did this it hard reset and I lost all customization. I had the accessory turned on setting it back up. Turned the acc off, started the truck and it's dead again. Anyone have an idea why? Cheap Chinese torture device? Thanks!
