MacBook Won’t Turn On? What to Try Before a Repair

A MacBook that will not start is stressful, especially if your work or coursework is on it. The good news is that the cause is not always serious. Work through these steps before assuming the worst.

1. Check the power

• Try a different wall socket and check the charger light or charging sound.
• Inspect the cable and USB-C or MagSafe connector for damage.
• Leave it charging for at least 15–30 minutes. A fully drained battery may need time before it starts.

2. Is it really off, or is the screen dark?

Press Caps Lock and see if the light comes on, or listen for fans. If the Mac seems to be running but the screen is black, try turning up the brightness or connecting an external display. If an external screen works, the problem is likely the display.

3. Force restart

Hold the power button (or Touch ID button) for about 10 seconds, release it, then press it again. Apple gives model-specific steps in If your Mac doesn’t turn on.

4. Try safe mode

If the Mac starts but freezes during startup, starting in safe mode can help rule out software problems.

Common hardware causes

• A failed battery: the Mac only works when plugged in, or not at all.
• Liquid damage: even a small spill can cause problems later. Read our MacBook water damage guide.
• A faulty display or display cable: the Mac runs but shows nothing.
• A logic board fault: the Mac shows no signs of life at all.

Protect your data

If the MacBook starts at all, back up immediately with Time Machine or iCloud. Tell us if your files are important before any repair begins.
