Was outside with my Nexus and it was briefly sitting on a magazine, so not exactly on the grass. Anyway, I came in, powered it off, connected the charger and nothing. So, with the charger still connected (and having been tested on my phone) I tried to turn it on. Nothing. So I tried powering on with the volume up also pressed. Again nothing. In desperation tried powering on with the volume down pressed, but still bothing. Then I panicked, thinking I had somehow got some damp into it. Googled 'my Nexus won't boot up' and came across advice to hold down the power on button for up to 30 seconds, and that did the trick. Connected the charger again, it charged and have now powered off and the white battery charging symbol is now there. But that was odd, and apparently not uncommon. Anyone else have this problem before?
