A MacBook that won't turn on is scary, but most of the time it's fixable at home in a few minutes. Work through this ladder in order and stop as soon as the screen lights up. If it's truly dead at the end, you still have options: keep reading.
First: is it charge, screen, or board?
Three very different problems look identical from the outside. Before you panic, figure out which one you have:
- No charge - the battery is flat and the charger, cable, or port isn't delivering power.
- Black screen, but running - the Mac is actually on (you hear a fan or the startup chime, keys backlight) but the display stays dark.
- No boot - real power is reaching the logic board but it won't start the boot sequence.
The steps below sort these out one at a time.
Step 1 - Charge it for 15 minutes (really)
A deeply drained battery can look completely dead - no light, no sound, nothing on screen. Plug in the original-wattage Apple charger, give it a full 15 minutes untouched, then try again. While it charges, rule out the obvious:
- Try a different outlet and, if you can, a different cable and adapter. Bad cables are the single most common cause.
- On USB-C MacBooks, test every port - one dead port doesn't mean a dead Mac.
- Look for a light: MagSafe should glow amber (charging) or green (full). No light at all points at the port, cable, or adapter.
Still nothing after charging? Move on - but leave it plugged in for the rest of these steps.
Step 2 - Force a power-cycle
This clears a hung power state and fixes a surprising number of "dead" MacBooks. Press and hold the power button (Touch ID key on modern models) for a full 10 seconds. The Mac should force-off. Wait a few seconds, then press power once, normally, to start it.
Do this even if you saw no signs of life - a frozen controller often refuses a normal tap but responds to the 10-second hold.
Step 3 - Reset the SMC (Intel MacBooks only)
Apple Silicon Macs (M1, M2, M3 and later) have no SMC to reset - a Step 2 power-cycle already does the equivalent, so skip to Step 4. On an Intel MacBook the System Management Controller governs power and charging, and resetting it revives many no-power Macs:
- Intel laptops with a T2 chip or non-removable battery: with the Mac off and plugged in, hold Control + Option (Alt) + Shift (left side) for 7 seconds, then add the power button and hold all four for another 7 seconds. Release, wait a moment, and press power.
Step 4 - Reset NVRAM (Intel MacBooks only)
If the Mac powers on but behaves oddly - wrong startup disk, a question-mark folder, no video output on Intel - reset NVRAM. Shut down, then power on and immediately hold Option + Command + P + R for about 20 seconds until you hear a second startup chime (or the Apple logo appears and disappears a second time). Apple Silicon Macs reset this automatically, so there's nothing to do here.
Step 5 - Tell a dead screen from a dead Mac
If you hear the fan, a chime, or the keyboard backlights but the screen stays black, the Mac is on - your problem is the display, not the computer. Check for this:
- Turn the brightness all the way up (F2) - it sounds silly, but a stuck brightness setting fakes a dead screen.
- In a dark room, shine a flashlight at an angle across the screen. If you can faintly see the desktop, the panel works but the backlight is out - a repairable fault, and the Mac still has real trade-in value.
- Plug into an external monitor. If the external shows a picture, the logic board and OS are fine and only the built-in display or its cable failed.
Still nothing? What it probably is
If you've worked every step and the Mac shows zero life - no light, no chime, no fan, nothing on an external monitor - the likely culprits are a failed battery, a damaged charging port, or a logic-board fault (often after a drop or a liquid spill). Those need a bench, not a keyboard shortcut.
Before you spend a dime: an Apple out-of-warranty logic-board repair often runs $500-$800+ - frequently more than the Mac is worth. It's worth pricing your options first.
Your options if it really won't turn on
- Trade it in as-is. A dead MacBook is still worth real money for parts. We buy them - see Sell a MacBook that won't turn on for current numbers and a same-day quote.
- Replace it for less than a repair. A certified refurbished MacBook Air (M1) starts at $450 and the M2 Air at $549 - usually below what Apple quotes to fix a dead one. Browse the current Apple clearance deals, and put your old Mac's trade-in credit toward it.

Frequently asked questions
My MacBook won't turn on but it's charging - what now?
A charge light with no boot usually means the battery is charging but the Mac is hung. Force a power-cycle (hold power 10 seconds), then try again. If it still won't start with a charge present, the fault is on the logic board, not the battery.
How long should I charge a dead MacBook before trying?
Give it a full 15 minutes on the original charger before deciding it's dead. A deeply drained battery shows no light or response until it crosses a minimum charge threshold.
My MacBook turns on but the screen is black - is it broken?
Not necessarily. If you hear the fan or chime, the Mac is running and the display or backlight is the problem. Max the brightness, shine a light across the screen to check for a dead backlight, and test an external monitor to confirm.
Is it worth repairing a MacBook that won't turn on?
Often not. Apple's out-of-warranty logic-board repairs run $500-$800 or more - frequently above the Mac's value. Compare that to a refurbished replacement from $450 plus trade-in credit for the dead one before you commit to a repair.
