If I run battery to empty Nexus 7 won't start up (after charge) unless I connect to computer

[Dylan Boudreau]

Hi all,
As the title says if I use my nexus 7 tablet until the battery runs dead then plug it in and charge it I can't get it to turn back on unless I connect it to a computer. As soon as I connect it to a computer and push the power button it powers up normally and works without issue. Once I get past that the power button works fine as do the volume buttons but for the life of me I can't figure out why I need to connect it to a computer for it to start after I run it empty so any advice would be helpful.

Welcome to Android Central! I'm afraid I don't have a concrete answer for you, but I would say that in general, it's best to avoid running your device all the way down until it shuts off on its own due to low battery. Completely discharging a Li ion battery is a good way to damage it irreversibly, and although I know that all devices should automaticaly shut down well before you get to zero, there's still risk, since you might not plug the device in promptly to recharge.

One thing I would check is to make sure your charging block still works. Will the tablet charge up when plugged into the wall at other times when the battery isn't really low?

I know when I've let my battery go completely dead I have to hold the power button on for much longer than usual for the initial boot up. It may just be you're not holding the button long enough.

are you using the original charger block and cable that came with the nexus 7? ive had similar issues due to trying to use my nexus 4 charger when i ignored my 7's battery indicator

I found this as well. I also found it seemed to take awhile for the charging to start.

Hi, yes I'm using the original charger block and cable. Seems to charge without issue even when it won't power on. When I do get around to connecting it to a computer to start up after a dead battery it reports that it is fully charged so that seems to happen even when the device won't boot.

It's a very odd problem and I'd love to know the reason for it as now I can't travel without a computer in case the battery runs dead while travelling which on a cross continent trip happens just about every time.

Oh and I've held the power button down for upwards of a minute and still doesn't come on but connect to a computer and it powers on in only a few seconds.

Guess I'm the only one that has had this problem ...was really hoping someone else would have seen this as I'm at a total loss as to how to fix. I've tried really hard to not let the battery go dead but still happens sometimes, particularly if I use it before bed when the battery is already down.

I'm having the same issue except mine won't boot at all.. I let mine run all the way down, charged it, and now it's stuck on the little splashy X thing. Won't get by it. Grr....

Actually people, its an easy fix (once you know how), connect to mains power then just press both the power button and the volume increase button at the same time and keep pressing till Google appears on screen. It's just a glitch that can happen if you leave the Nexus 7 idle for a long period of time, or if you let the battery run down completely. I hope that helps!

Don't let the battery go completely dead on any modern devices. I understand you are away from a charger sometimes but you can still shut down the device at 10-15 percent until you are able to charge.

It's not a problem or a defect, just don't run it all the way down.

Re: If I run battery to empty nexus 7 won't start up (after charge) unless I connect to computer

I have a slightly different battery issue, after charging on a third party charger overnight, my 1st gen nexus 7 flashed the on screen battery empty signal the next morning. It only showed a couple of times before the device died completely and has showed a black screen ever since. I've tried every combination of holding the power and volume buttons, as well as plugging it into the official charger and a computer, I'm getting no response from the unit. I've checked the battery connection and it's fine, even disconnected it and left it off a bit to see if that prompted a restart.

Replacement batteries are way expensive for a unit that now retails at ?99 so I'm really not sure it's worth going that route, anybody got any ideas?

Thanks

Google's help center offers that you can backdoor the boot by pressing 'volume down' and then holding the 'power' button for 10-15 seconds.
My wife let hers sit in a computer case for months and it is now taking a long while to charge.

Thanks Stew Craig.

Your advice worked for me. Not sure why it died as my battery was at 97%

 

[RainFace DeathMonkey]

Guys, listen to him. I've had this problem many times, and he was 100% dead on. Hold the power down for much longer than normal, and it should start right up.

 

[Sasha Edwards]

HELP! I have unfortunately let my Nexus 7 die a few times due to neglect. It is fully charged and yet I can't seem to get it to turn on completely, it seems to get stuck on the screen after the Google screen...I'm extremely frustrated. I've tried EVERYTHING that I've read to try and yet no results. Super bummed. Any new tips I could try?!

Thanks!
