Hey I recently installed nexus 7 in my car and hardwired the USB cable to Fuse box.So whenever i start my car,my tablet turn on and when i turn it off my tablet goes to sleep mode.If i don't drive car for a week , the tablet shuts off .So i have to open my dash again to power on.Which is pain to open .so is there a way to solve this problem ? Suppose when i turn on my car , will my nexus 7 turn on from an off mode ,instead of charging in background ?
You have asked this question 2 times in the last 2 weeks... The answer is still no. Do not start another thread asking about it. You are spamming.

There was 2 posts exactly like yours the day before you posted. I'm not surprised you missed. No one ever uses the search function. Also, pro tip, when you don't get an answer, you don't post the same stuff again. You bump the OP. And normally when you post about the same thing multiple times and no one answers, it normally means no.

Xposed framework and MoDaCo module. I'm think it has a setting for that. Check the module info before you bother installing Xposed. Requires root. Both available here at XDA.
Second possibly. Timur's kernel, fixed installation version. More info: http://mehrvarz.github.io/usb-host-mode-power-management-nexus7/ Requires root. Seems custom made for your issue.
Trouble is you could have found the kernel mentioned and described in the myriad of threads here on car installs if you simply searched. Perhaps that's why nobody bothered to answer you.

Usb-rom by Timur, is the best option for an in dash install. It was literally made for just that scenario. Designed for in dash installations, and provides all the power and host mode charging options you need specific to this kind of operation. A quick google of timur usb-rom will get you where you need to be.

X posed nor a kernel can enable what OP is asking for. It is in the bootloader. Since the bootloader is not open sources, it can't legally be done.

So... I cannot turn on my Asus tf101 unless I plug it in to a power source, once the screen lights up I can unplug it immediately and it functions normally when turned on. I bought this device refurbished from best buy a few months back, I dealt with the issue but now am looking to sell it. Any ideas on how to fix this? I have never rooted the device, however I have tried factory resets and cold boots.

Are you holding the pwr button long enough. If so,it sounds like the switch is bad.
I hold the power button for 12 seconds and try it with different variation holding volume keys. It functions fine when the device is powered on.

It could be a bad battery or your charger is only giving enough to power the device on. I would try a new charger first.

But once powered on, it functions flawlessly. The only issue is turning it on.

Do you have the keyboard docking station for it?
Are you on custom ROM or OEM?
What "app killers" are you running?
Some custom ROM's have had similar issues a long while back. maybe yours is getting that issue IF your running custom.
Keyboard dock, if you have it, does it do the same thing for powering on, where it needs to be plugged in to start the screen?
I only ask about the app killers because I had experienced a similar issue about a year ago due to an app killer I had installed. Removed it, and the phone worked fine. Put it back on and it reverted back to having to be plugged in to start the screen.
Have you tried a clean wipe of everything on the tablet? And I do mean CLEAN, no dirty flashes here (keep your pants on bud).
Lastly have you given the charge port a good ole blow out lately? Long bursts aren't really going to do any damage, but I would stick to short quick bursts of compressed gas, again NO VACUUM CLEANERS. They create static and the charge port is quite susceptible to static discharge.
I know your pretty intelligent, but let me put it out there again. DON'T be a fool and use alcohol on your tool.
This post made me laugh. I do not have the keyboard docking station. I have never installed any task killers as I do not believe in them. The tablet has been running the stock ROM the whole time and has never been tampered with.

But you never said if you gave the ole girl a good ole cleaning in the slot.
I would venture to say that you need to send it in to Asus or take it back to Best Buy (if your able to). It sounds like there may be a voltage issue with the digitizer or the inverter.
And NEVER EVER EVER Invert your digits while cleaning out the slot.
You also didn't say if you went deep up in the ole girl and gave her a good rootin.
I'm working with Asus right now and of course there's something wrong with my serial number. Nerve been rooted. Blew it out and that did nothing.

Please keep us posted as I am curious to know how ASUS customer service is to deal with.
Well, I am trying to send my TF to Asus to fix the problem and they are a bit annoying. I have just dealt with HTC before and that was wonderful, but here they have send me 4 emails asking me to wipe, to update and to do everything that I have already done, and after that they have sent me to another web to fill another questionary. With HTC I just had to told them the IMEI and in 4 days I had my phone back
I had similar issue with mine. It was one of the reason I took back to best buy and used the buy back.
I then picked up the Nexus 7.

I had a similar issue, do you use your device often ?
I figured out after a couple of months that each time it showed this behaviour the battery was in fact empty and it was in fact the root of the problem.
My transformer take much longer time to boot when plugged even with a full battery, and when it's empty it doesn't boot at all.
I must plug it, wait for it to be enough charged to boot unplugged, and do so. Then plug it back when started.
Considering that the transformer on stock cannot shut off when plugged to its keyboard (or even to USB ? Or is it just mine ? When I shut it off plugged to the keyboard then close it, it boot on again) When the tablet is left for several days unused the battery will be empty.

Yes I do. But even if the device is fully charged it will still not power on unless plugged in and I don't have the dock.

Do the power and volume buttons work normally once fully booted? I have had similar issues, one was improperly seated power button, the other was a loose ribbon cable way down in the guts of this beast. Also, was this happening the whole time you've had it , or after a firmware update?
Right now I'm dealing with one that the screen won't stay on once I get into ics unless I'm plugged in. I went in and noticed that if the auto brightness wasn't set, it works. So I tweaked the settings in display time off when unplugged and uninstalled some screensaver app, and now it's working fine. It was probably the first thing, even though was already set to one minute. Anyway, just letting people know sometimes it isn't hardware. But the op probably is since he's done factory reset.
Everytime I flash a new rom and go to wifi setup in begining I enter the wifi key correctly but my N7 just sits there and it says
"Saved. secured with WEP" . Never says connecting ?!?!? WTF . thanks
I have no issues. Using Linaro AOSP latest.

I'm just learning reading xda myself, if I remember correctly it's your current kernel not matching. Seems I read that on a couple different threads.???? Keep reading and someone please let us know if I'm wrong. Thank you

I have a case on my Nexus 7 that uses the four sensors on the side to turn the screen on and off. I was using the tablet just fine, then I close the case like normal, and upon opening it, it would not turn on. The only way to get a response from the device is by plugging it in and the screen just lights up black. Any type of power reset using the button combinations result in the screen shown in the video at the end of the post.

Sorry I can't post the link. I don't have 10 posts yet.
Solution: I removed the back cover and disconnected and reconnected the battery.

Not that I can recall. The tablet is purely my Portable Netflix/Evernote slave. I've left it on the wall charger for 24 hours, and on a usb port charger for 24 hours, to see if that helps but that won't do anything.

If you don't have anything important saved, you might to just try and wipe everything and start fresh. Are you rooted?

Check the stickies in the dev section, they will show you how to root/unroot and flash back to stock. You can likely just use the updated nexus 7 toolkit.

All of the options are saying it needs to be in ADB or in Android. I can't get it to show any of those screens to verify I'm in that mode.

Good deal!
There have been a couple threads where folks reported similarly-behaving screens. "sparkles", "static", "like an old tv screen", et cetera. I think at least several of them were similarly traced to battery charge issues or loose terminals on the battery connector.
Maybe add "[SOLVED]" to your thread title and it will help future visitors with the same issue.
cheers
So my nexus had been unplugged and without charge for about 3 weeks or so, I've been very busy at work. I try and connect the tablet so that i can use again and the screen flickers for an instant and nothing happens, I don't see the white icon charging animation and no response after that. It's my tablet done or is there a solution for this. Thanks to anybody that can help.

Ok, I don't really know what exactly the problem is. But I think the battery seems to be dead. because if it is still good, at least it shows the indicator light when it's plugged with charger.. If u have a simple tool to test battery energy maybe u can find out. or maybe try another battery..
Leave it plugged into the charger for a good while and then hold down the power button hard, for about 30 seconds. See if that forces it on.
How long did you leave it plugged in for? It may take a few hours...

It was plugged for like an hour or so and no dice.

Try leaving it plugged in overnight. I once had a laptop battery die on me, had to plug it in for like a week before it would turn on again.

Your device is hibernating to prevent further damaging the battery. Plug it in... boot to bootloader... select power off using the volume keys... the tablet will now charge normally

hi
My problem is solved, I have a friend who had the same problems with the tablet Nexus 7 16GB, the back of the unit opens easily with just a fingernail to open a case as remote and actually the battery plug is not fully inserted into the camera, a little bit of nail to reconnect the cable and now my tablet displays well 100% load.

Yup - there is a sticky that covers this method, and all the other methods as well. For anyone else suffering from similar N7 issues, be sure to check it out. Either go to stickies in this Troubleshooting section, or use this link.
You probably get these all the time so apologies.
I've done the google and the msm_hsic_host is referenced for when you connect the phone via usb.
But the problem I have is it's there all the time, regardless of using a computer USB cable or using a wall charger.
These appear far too often, reboots help but there seems to be something wrong and I cannot figure it out.
Any and all help / advice welcome becuase it's really fustrating.
Cheers
What OS are you running? Could it be an app you installed? Have you tried flashing to stock to see what happens?
On stock 4.2.2
Will have to see on the app front.. Might do a purge and see if it helps.

Good luck. Please report back with your findings.
I was on stock 4.4.2 and got pretty good battery life.
Lol OP, I think what you're using is 4.4.2 not 4.2.2. It's time to get it right now, don't you think?
Btw, are you using stock kernel or custom? Either way try flashing stock kernel back and format dalvik and cache. If you're using custom kernel, same..flash stock kernel back then flash your kernel.
Sigh you are right. 4.4.2 of course.
Everything is stock on my nexus4, haven't even rooted it.
Which is why this behaviour is so annoying, might understand if I'd have played around with roms etc.
I've deleted loads of apps, may remove some more today if it doesn't let out. Will then think about going for a wipe down.
Cheers for the suggestions.

From what i've read, this wakelock is not about the USB cable per se. The 3g modem is connected to the phone as an external USB device, which is controlled by the msm_hsic_host.
In few words, every time your phone needs something from the 3g modem, msm_hsic_host is triggered.
Im on 4.4.2 stock rooted and every time I'm in a place with low signal this wake lock drains a good amount of my battery.
Maybe you should try different kernels to see if that helps.

Using other on better battery stats shows the phone is never in deep sleep.
