How to disassemble ASUS Google Nexus 7 tablet 8/16/32GB and replace I/O ribbon board with stereo audio headphone jack & micro USB DC IN power jack
Today we'll discuss a very common problem - the device doesn't charge when connected to the power supply. The reason is probably a broken micro USB port.
ASUS Google Nexus 7 is a really cool tablet. As soon as it was announced, immediately everyone wanted to buy it. But I'm not part of a consumer society, because blood of an engineer flows in my veins ;) and the rush to buy it did not flush upon me. I decided to wait for all the defects to show up.
Six months later, when I got hold of my first Nexus 7, I was pleasantly surprised. The thing had a very high quality assembly (nothing squeaky or loose). A customer brought the tablet to repair the following problem - the device didn't charge. I saw immediately that micro USB port was damaged and after reading the documentation it turned out that I needed to change the DC USB/Power/Audio/Jack Dual Board.

Use guitar pick to open the back cover. Gently press around the cover.
Inside most of the space is taken up by the battery.
The battery must be disconnected in the first place.
Now unscrews the speakers, then remove them.
Unscrew the DC USB/Power/Audio/Jack Dual Board and disconnect it.
And that's how the replacement is done. Now replace with a new board and repeat the procedure in the reverse order.
I really like how this model is designed and not just outside. You can easily replace almost anything in it. May the power supply be with you!
