What GPU does the D80 use - I did a quick Google for "zotac zbox d80" but came up empty, are you sure that's the model number? Please provide a full debug log and dmesg.

I'm wondering is it this Zotac he's talking about,with a
NVIDIA GeForce GT520M Zotac ID80 ?

Could be, in which case the updated nvidia driver would be the obvious candidate for breaking standby (in which case there's probably not much we can do).

@xxxnelly if your Zotac box is using an nvidia GPU, try build #0709x - this is the same as #0709 but uses the older 340.96 driver in place of 367.27. This should help confirm the standby issue is being caused by the latest nvidia drivers.
