Setting up sleep schedule on laptop question

[ernenr1]

Hi! I currently have Raspbian Desktop installed on an old Thinkpad x41 tablet in which it runs MagicMirror. Everything is mostly set and ready to go before I mount the laptop on to my wall. The only thing left is to somehow set a sleep schedule. I was wondering what would be the best way to accomplish this?

I read that people use cron jobs to accomplish this task, but I have a feeling it only works on RasPi’s attached to an external display. Is there any way I can create a cron job to put my laptop in a sleep or suspend state? If that isn’t possible is there any way turn off the LCD display? The laptop will always will be plugged into an outlet. The specs are as listed:
