I prefer to leave my computer in Hibernation. But I don't know if scheduled applications like defrag., virus scan etc., will run if not left in Standby. I use windows xp sp2.
Thank you

   No, I don't think it will.

Hello,
At the Church that I am a member of, we are useing a software that plays audio files at scheduled time intervals ( a Electronic Church Bell Carillon, Bell Tower ) normally it is scheduled to play 5 times during the day. I tried using the Hibernate function in power management, so that the computer would not have to be on all the time. Only when the scheduled time called for a function.  It Would Not Work After Going Into Hibernation.
Using the Turn Off Monitor and the Turn Off Hard Disk Functions Worked OK. Thus saving some power and wear on idle system usage.

Thank You and Ray for the response's. I will reset schedules  to perform in one night, then leave in stantby for that night.
