The Sleep Indicator Light (SIL) on your MacBook, MacBook Air, and MacBook Pro has different behaviors based on the state of your Mac. These behaviors also occur on some iMac, Mac mini, and Mac Pro models, though not all Macs have a SIL.

Macbook Pro screen off when waking from sleep. Start date Feb 17. I would open the lid and the screen would be black yet the computer would wake up.

Macbook pro black screen after sleep Over 340 peer-reviewed studies verify the benefits of the Transcendental Meditation technique for reducing stress and improving performance and quality of life. I recently got a u3419w. I connected my keyboard and mouse to the usb hub and switch inputs between my PC on DP and the Macbook on usb-c. When I am using the PC with the Mac connected, it eventually goes to sleep and despite being on the DP input, a 'usb-c input disconnected' message appears. I have seen, including on my own MBPr, that it can boot or wake up out of sleep with an initially weird screen. Screens like white with all kinds of static on it, bright flashing screen, etc. The other day my work MacBook Pro (a mid-2012 15 inch MacBook Pro running OS X 10.7 Lion) started having problems waking from sleep. When I opened the lid, I could not move the mouse or type my password to log in. The trackpad and keyboard simply did not work.

After you press the power button

Every time you turn on your Mac, it performs various hardware checks, known as a Power-On Self-Test (POST).

If the SIL flashes one or more times after you turn on the computer, and the pattern repeats after a brief pause, the computer may not have successfully passed POST.

  • If your computer has hardware issues during POST, it might use a combination of audible tones and blinking SIL behavior to communicate POST issue codes.
  • To find the cause of a POST issue, see Intel-based Mac Power On Self Test RAM error codes.

During startup

Pro

When you press the power button to turn on the computer, the SIL also turns on. As the computer starts up, the SIL stays on until the processor (GPU) has initialized and the display turns on. When the GPU initializes properly, the display turns on and the SIL turns off simultaneously.

On Mac mini models from 2011 and newer, the SIL stays on when the computer is powered on.

During operation or display sleep

While the computer is operating, the SIL remains off. If the display turns off but the computer is still on, the SIL turns on and does not blink. It remains like this until the display turns back on, at which time the SIL turns off again.

On Mac mini models from 2011 and newer, the SIL remains on when the computer is operating.

You can turn on Display Sleep by pressing Control-Shift-Eject. To change your Display Sleep settings, drag the 'Turn display off after' slider in the Energy Saver pane of System Preferences.

When your Mac sleeps, the SIL pulsates on and off slowly. On Mac mini models from 2018, the SIL stays on when the computer is in sleep. You can customize your Mac's sleep behavior in the Energy Saver pane of System Preferences.

On Mac notebook computers, if the battery is completely depleted and the computer goes into Safe Sleep, the SIL doesn't illuminate at all.

During shut down

When you choose the Shut Down command, macOS first turns off the GPU. This turns the display off. When the display turns off, the SIL turns on. During the few seconds of shutdown, but before power is removed from the main logic board, the SIL remains on and will not blink. When the computer is fully shut down, the SIL turns off.

On Mac mini models from 2018, the SIL turns off when the computer is fully shut down.

Diagnostic uses

Through
  • You can use the SIL as a diagnostic visual to determine whether the computer is getting power at startup.
  • If the SIL of a MacBook Air (Original, Late 2008, or Mid 2009) flashes five times when starting up or after waking from sleep, and the pattern repeats after a brief pause, the computer's battery may require service.

The other day my work MacBook Pro (a mid-2012 15 inch MacBook Pro running OS X 10.7 Lion) started having problems waking from sleep. When I opened the lid, I could not move the mouse or type my password to log in. The trackpad and keyboard simply did not work.

After a quick internet search I came across a support page on Apple’s website that seemed to describe the problem. I followed the instructions for “Resetting the SMC on portables with a battery you should not remove on your own” which includes MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009). This seems to have fixed the issue. Note that this will reboot the MacBook, so you will lose any unsaved work.

This is the first time I’ve had the issue in nearly a year of daily use. I’m constantly moving my MacBook around from a Thunderbolt display at my desk to various conference rooms with HDMI and VGA projectors at work and to an HDMI monitor at home. I’ve been extremely impressed with how convenient and simple the MacBook is to move around between workstations, so I don’t think the problem happens often, but if it does I hope this solution helps!
