    My Nexus 7 (since last Friday) has gained an amazingly annoying fault. When it goes to sleep it shuts down and only a hard reboot (holding down power button for twenty seconds) starts it up.

    This morning I decided to wipe the Nexus 7 back to factory settings, however the Volume Down+Power took me to the Recovery mode screen however the Volume Up+Power refused to start the reset device. I had to go into the device, settings and then reset.

    Hoping this resolved the issue I return to my device after inputting my information and discovered it had once again shut itself down, restarting it I watched the device and when it went to sleep again the sodding thing once again turned itself off.

    ***** UPDATE *****
    Managed to attempt the proper Wipe and received this message.

    Formatting /data
    Formatting/ cache
    E: failed to mount/ cache (invalid argument)
    E: Can’t mount /cache/recovery/last_locale

    and also

    E: Can't mount / cache (Invalid argument)
    E: Can't mount /chance/recovery/last_install
    E: Failed closing /dev/block/platform/sdhci-tegra.3/by-name?MSC (I/O error)
    E: Can't mount / cache (Invalid argument)
    ***** UPDATE ENDS*****

    The device hasn't be dropped and I don't install any random pieces of junk willy-nilly on my machine (plus I have AVG watching what goes on too).

    Has anyone seen this before and if yes what can I do to resolve it?

    Thank you

    Mine does this pretty routinely too. Did it from the day I had it. It used to do it while it was unplugged, but also will do it while it is on power. It is pretty annoying. I had the chance to RMA it back in the day, I should have taken it. Not that the replacement may not have the problem, it seems pretty common.
