My MacBook Pro doesn’t wake up after sleep mode I have a MacBook Pro 13" (2013). After it goes into sleep it does not wake up. I see the tabulator key light goes on if I press it, but the monitor stays black. I can only restart the Mac by pushing the on/off key.
In cases like this you should try to do a PRAM and an SMC reset. You can see how to do that here and here. Don't worry you won't loose any data.
