Server 2012 Essentials Auto wake up and Sleep mode?

task scheduler is your friend here.

The wakeup will be the hard thing.
You will need to configure WAKE ON LAN to wake it up.

It is not normal practice to have a server go to sleep. Normally it turn it on and let it run and schedule restart periodiclly.

In an office environment I woudl always suggest leaving the server on 24 hours a day seven days a week.

Shutting down the disks every day will lead to a shorter lifespan for the disks, the extra electricity consumed will be peanuts compared to having issues because of failed disks.

If you have a timed shutdown and for whatever reason your backup fails to complete in time, the backup will not complete, this can cause other issues.

I tried with task scheduler but unfortunately didn't get the success. if you have any script for that then please provide.

thanks.

I do not think you can wake a computer from Sleep Mode using a task as I stated in my previous reply.  As other reiterated you server should be available 24 x 7.

Some computer BIOS's (and the EFI replacements)  can be set with a switch on time...

However, as previous, I would recommend leaving it on 24/7

What is the function of this server?
Why do not need it to go to sleep?

@ yo_bee

21 user are connected to the server & from morning 9 AM to 8 PM they access their data by logging to the server  that's it.

@yo_bee

ok yo_bee as you said in your previous comment that to start a server from sleep is not possible. but sleep mode is possible ? if yes then how  ?

Try this, but I do not recommend it as it is bad practice.

@ yo_bee

I also tried that but didn't get the success.

Any other option  ?

Not getting the success :(
