MacBook Air 11" A1465 2013 Sleeping Mode Twich

Question

Hi, I seem to have a problem with my Mac. Everytime it wakes from the sleeping mode the screen goes normal and everything seems fine, but 4 seconds after it goes to sleep mode again and I have to move the mouse again in order to work. Is this some bug? or is just some crazy energy saving set up. I was in the genius bar and they said my computer has no problem whatsoever and that I should wait for an update from Apple. Can please somebody help me. Thanks
PS: My laptop is not connect it to the charger.

Answer 1

You took all the reasonable actions that can be expected. Read the following Apple Support document to be sure there isn't anything you may have overlooked:
Troubleshooting: My computer won't turn on - Apple Support
It seems unlikely that a catastrophic failure would coincide with what you did, so perform the NVRAM and SMC resets again, making sure you did both of them properly. After that, schedule a Genius Bar Reservation.
The SMC reset procedure is linked in the above document. The NVRAM reset is as follows:
NVRAM reset:
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. If issues persist, your Mac's logic board battery (not a portable Mac's rechargeable battery) may need to be replaced. The logic board battery helps retain NVRAM/PRAM settings when your computer is shut down. You can take your Mac to a Mac Genius or Apple Authorized Service Provider to replace the battery on the logic board.
