Monitor and MacBook Pro go into sleep mode when closing lid

When I close the lid on my MacBook Pro, it automatically goes into sleep mode and therefore my monitor shuts down. Appreciate any help! - Steve

Eric_G1 answered your question. Allow me to reinforce what he said:

Unless/until you connect an external POWER source, your Mac will go to sleep when the cover is closed, by design.

Hello PapaDil,

This page can help out with providing helpful info on using an external display with the Mac: Connect a display to your Mac

If you use an external keyboard and mouse with your Mac notebook, you can close the built-in display after you connect your external display. You might have to press a key or click your mouse to wake the external display. To use your Mac with the display closed, you need to connect your power adapter or connect an external display that also charges your Mac, such as the Apple Studio Display or 23.7-inch LG UltraFine 4K Display.

Cheers.
