Deep sleep problem

I have a Prestigio MultiPad 7.0 Prime 3G and I don't know if this tablet has a deep sleep mode?
It has Android 4.0.
Does Android 4.0 have deep sleep mode?​
 
I have installed Wakelock detector that says that device never goes to deep sleep, its always awake.
There are Android OS Screen locks and CPU locks, but I don't know what they mean.
How to solve this?
 
If you head to the Accounts screen, is anything constantly syncing/are there sync errors?

If it's Android OS that's keeping the CPU awake, it's pretty hard to diagnose exactly what is ticking over. :(
 
Sync is off for all accounts.

I wonder if my tablet does even have deep sleep option.
I have an older tablet with Android 2.2, and there I can choose between Sleep and Deep Sleep option for button.
On this tablet with Android 4.0, in Settings there aren't any mention of Deep sleep, just Sleep, which makes me wonder is Deep sleep available at all?
