A Mac that will not turn on, no chime, no screen, no sign of life, is genuinely worrying, especially if you have work to do. The reassuring news, based on the most common causes and widely reported fixes, is that the problem is usually power, a stuck state, or a simple glitch, not a dead machine. Work through these eight fixes in order, starting with the simplest, and your Mac will very likely come back to life.
First, Is It Power or the Mac?
Start by working out whether your Mac is getting power at all. Look for any sign of life, a light, a fan, a sound, the screen flickering. A Mac that shows nothing whatsoever is often simply not receiving power, which is the easiest problem to fix, while one that powers on but shows a black screen has a different cause. Identifying which situation you are in points you straight to the right fixes and saves you chasing the wrong problem.
1. Check the Power and Charger
The most common reason a Mac will not turn on is simply no power. On a laptop, make sure it is plugged into a working outlet with a known-good charger and cable, and leave it charging for a while in case the battery is fully drained. On a desktop Mac, check the power cable at both ends and try a different outlet. Confirm the outlet works with another device. A surprising share of dead Macs are just out of charge or on a dead outlet.
2. Check the Screen and Brightness
Sometimes the Mac is actually on, but the screen is black, which looks identical to a Mac that will not start. Listen for a startup sound or fan, and look for a faint backlight glow. Turn the screen brightness up using the keyboard, in case it was turned all the way down. On a desktop Mac with an external display, confirm the monitor is on, connected, and set to the right input. A working Mac with a dark screen is a much easier fix than a dead one.
3. Force Restart Your Mac
If your Mac is unresponsive, a force restart often revives it. Press and hold the power button firmly for about ten seconds until the Mac fully shuts down, then wait a moment and press it again to start up. This forces a stuck or frozen Mac to reboot, clearing the kind of hang that leaves it dark and unresponsive. It does not erase anything, and it is one of the most effective first steps for a Mac that will not start normally.
4. Disconnect Accessories and Peripherals
A faulty accessory can sometimes prevent a Mac from starting properly. Unplug everything, external drives, hubs, printers, and other peripherals, leaving only the power, then try to turn it on. If it starts up with everything disconnected, a peripheral was the culprit, and you can reconnect them one at a time to find the offender. This simple step rules out a surprisingly common cause of startup trouble that has nothing to do with the Mac itself.
5. Let It Charge and Try Again
A deeply drained laptop battery can be too low to start, even when plugged in, and may need time before it will power on. Connect the charger, leave it for fifteen to thirty minutes without trying to start it, and then attempt to turn it on while it is still plugged in. Pairing a proper charge with a force restart often succeeds where either alone failed, reviving a Mac that simply did not have enough power to boot the first time.
6. Reset the Power Management Settings
If the Mac still will not start, resetting its power-management settings often resolves stubborn startup problems, since these settings control power and the boot process. The exact method depends on your Mac model, and on the latest models much of this reset happens automatically when you force restart and let it sit unplugged briefly. Look up the correct reset steps for your specific model, as it is a well-known fix for a Mac that refuses to power on after the basics check out.
7. Try Booting Into Recovery
If the Mac powers on but cannot start up normally, getting stuck or showing an error, booting into its built-in recovery mode lets you repair the disk or reinstall the system. The key combination to enter recovery depends on your Mac model, so look up the right one for yours. From recovery you can run repair tools that often fix a Mac that powers on but will not finish starting up, without losing your files, before you consider anything more drastic.
When to Seek Professional Help
If you have checked the power and charger, ruled out a dark screen, force restarted, disconnected accessories, let it charge, reset the power settings, and tried recovery, and the Mac still will not turn on, it may be a hardware fault such as a failed battery, charger, or internal component. At that point, contact Apple support or a trusted repair service. A battery or power-component repair is far cheaper than a new Mac.

| Symptom | Likely fix |
|---|---|
| No sign of life at all | Check power, charge, force restart |
| Sounds on but black screen | Raise brightness, check the display |
| Powers on but won't finish starting | Boot into recovery to repair |
Quick Answers
Why won't my Mac turn on?Usually no power, a drained battery, or a stuck state, rather than a dead machine. Check the charger and outlet, let it charge, and do a force restart, which fixes most cases.
How do I force restart a Mac?Press and hold the power button for about ten seconds until it fully shuts down, then wait a moment and press it again to start up. It does not erase anything.
My Mac makes a sound but the screen is black, why?It is likely on with a dark screen. Raise the brightness, and on a desktop confirm the external display is on and set to the right input.
Could an accessory stop my Mac starting?Yes. A faulty peripheral can block startup. Unplug everything except power and try again; if it starts, reconnect devices one at a time to find the culprit.
What is recovery mode for?It lets you repair the disk or reinstall the system on a Mac that powers on but will not finish starting up, often without losing your files.
When should I get my Mac repaired?If power checks, a force restart, resetting settings, and recovery all fail, a hardware fault may be to blame. Contact Apple or a trusted repair service.
The Honest Bottom Line
A Mac that will not turn on is usually fixable for free. Check the power and charger, rule out a dark screen, force restart, disconnect accessories, and let it charge before you assume the worst. Resetting the power settings and booting into recovery handle most of the rest.
Only when every step fails is a hardware fault likely, and even then a repair is far cheaper than a new Mac. Which fix worked for you? Tell me in the comments and I will help with stubborn cases.
