Have you got a startup service set?
I have enabled StartUpToStandby if you mean 'startup service' by that.
I have Power Timer set every day to Deep Standby and next morning wake on to Standby.

EDIT: Made a Power Timer test (deep standby --> standby) with StartupToStandby disabled and box doesn't go to standby, but it is activated to latest service.
