My Mac display goes black and locks like I just closed the mac when I simply adjust the display a tiny amount. My screen would be open completely and by simply adjusting the angle of the screen the display goes black and locks like I have closed it. Why does this keep happening?
MacBook Pro (Retina, 15-inch, Late 2013), macOS High Sierra (10.13.2)
If your Mac goes to sleep unexpectedly
Make sure that Energy Saver is set up the way you want: choose Apple () menu > System Preferences, then click Energy Saver. Adjust one or more of the following controls to affect when your Mac goes to sleep. Some of these controls might not be available on your Mac.
- "Turn display off after" slider
- "Display sleep" slider
- "Computer sleep" slider
If a slider is set to "Never," sleep is disabled for that feature.- Schedule button
Make sure that you aren't putting your Mac to sleep accidentally:
- Pressing the power button can put your Mac to sleep.
- Moving your mouse pointer to a hot corner can put your Mac to sleep, depending on your Mission Control settings. Choose Apple menu > System Preferences, then click Mission Control. Click the Hot Corners button, then see if any of the corners are set to "Put Display to Sleep."
- Using magnets near your Mac notebook can put your Mac to sleep.
If the previous steps don't work
These additional steps may help identify or resolve the issue:
- Reset the SMC.
- Reset NVRAM.
- Disconnect external devices other than your Apple keyboard, mouse, and display. If that resolves the issue, gradually reconnect your devices, testing each time, until you find the device that is interfering with sleep. Then check the documentation that came with the device, or contact the device manufacturer.
- Start up in Safe Mode to see if the issue is related to non-Apple startup items, login items, or kernel extensions.
- Try to isolate the issue by using another user account.
If you still see the issue, contact Apple Support.
