MacBook Pro 13INCH not turning on

If your Mac doesn't turn on or start up - Apple Support

Your computer is sleeping. That is the meaning of a pulsing front lid lamp. Did you try rebooting it? Impossible to tell what is happening because of your poor photography. You could have described it better with words.

You have not provided sufficient information for even determining what may be the problem. Please read Writing an effective Apple Support Communities question. We are here to help. We are all users. We are not mind-readers nor clairvoyants. We only know what you write down and tell us. Be specific and thorough. Include your hardware information and installed version of macOS.

1 beep = no RAM installed

2 beeps = incompatible RAM types

3 beeps = no good banks

4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

5 beeps = processor is not usable

In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
