Nexus 7 doesn't charge when on, but charges when turned off?

Superpopsss · Sep 25, 2012

It's really weird. When my nexus 7 is on, it won't charge or connect to the pc by usb, as if the usb port doesn't work. When I turn it of it charges normally, not problems whatsoever. I tried with factory cable and charger still same issue.

I don't have the receipt to return it so I have to find a fix, any ideas?

Raplacing the usb port might do the thing or is it something else? Is someone having this issue?

Thanks

You don't have enough power on your USB port. Mine charges via usb just fine while in use. My car charger does what yours is doing.

I'll assume it charges fine when using the ac charger that came with your n7?

Why you can't connect to your PC...I don't know. Like you said...maybe a bad USB port. I'm using an Asus USB 3.0/SATA lll PCI card.

Read the documentation. It does not support charging over USB while in use. There's not enough power through a computer USB port.

It doesn't charge even if I plug it in the wall. I have to turn off my nexus to charge it!

I have the exact same problem. Mine won't charge when on and will not connect to PC via USB. Did you ever find a solution?

I had the same problem, it turned out to be an iffy USB cable. Grabbed one of the kids micro USB cables (for their phone). Fixed the issue for me.

Doesnt matter what kind of cable I use or charger. Cant get it to do anything but Stickmount still works somehow.

Sorry to dig this out. Have the same problem as OP for a few month. Now I'am annoyed enough to find a solution.

Anybody with good advice?

Cable/charger won't matter: if GN7 is on (either active or standby) it won't charge (or get recognized by PC). If switched off, it charges anywhere (wall mount charger, PC USB, ...)

I'm also having this same problem and have been unable to find a solution after about an hour or so.

same problem

I bought my n7 on 11-30-12. In the last month or so its developed the same problem. I called Asus for warranty. The guy says you can send it to Texas for it to be studied and repaired but it will take a LLLOOOONNNGGGG time. He said I should wait til the factory warranty ran out and hope Wallyworlds extended warranty offers to replace it with a new one. I tried taking the back off and unplugging-replugging it, didn't help. I tried a factory reset, didn't help. Guess I'll keep trolling the interweb for ideas til the end of the month and hope Wallyworld gives me a new one!

Either way its the last asus for me. I may have to sharpen my teeth for all the crow I'll have to eat when I show up for a visit at my brothers' homes with an ipad air...

I had this problem with my Nexus 7 (2013). In my case, the usb charging port on the tablet was severely damaged. This caused the USB port wires to short with each other. USB charging was obviously not possible. However, the unit would charge with the wireless charger--but only when off.

Since I had a wireless charger, and the USB port was destroyed already, I took a hemostat clamp and physically snapped and removed the USB charging port and wires. Once the USB wires were no longer shorting, the wireless charging worked flawlessly.

If you don't care about USB charging or connectivity, this workaround may work for you. Otherwise, you may consider a daughterboard replacement or replacing the USB port.

Hope this helps...

You need a good wall charger, a USB port on your computer isn't going to cut it. Buy one of the high power ones from Amazon. I find mine will hold at whatever level it is at now with my Kindle's wall charger if I'm using it but will charge pretty quickly when the screen is off.

I know this is an old thread but I acquired a nexus 7 2012 from my sister. She said it doesn't charge. I did a factory reset and found that it charges when it's off and holds charge so the battery is out the equation. I purchased a new usb port and fitted and although the USB fits a lot better it still only charges when it's off. I've used plenty of wall chargers Sony, Samsung but won't charge when it's on at all. Anyone get to the bottom of this?

Thank you

This is an old thread, but I have the same problem. My N7 charges only when turned off no matter which cable or charger I use.
