While Time Machine is backing up the macbook monitor can go to sleep?

Hi lalipatti,

Thanks for reaching out in Apple Support Communities. I understand you'd like to know if it's possible for Time Machine to perform a backup, while your Mac is asleep. I can help provide you additional information.

If your Mac supports Power Nap while it's asleep or if it's asleep while connected to an AC power outlet, you can use Time Machine to perform a backup. Here's a helpful article with that information: How Power Nap works on your Mac

Kind regards.

Eventhough the article explains related to power nap, My question simply is while Time Machine is baking up; my MacBook Pro display can be on screen saver. Thanks for your answer.

Yes.
