Your MacBook is asleep. You press a key, tap the trackpad, open the lid — and the screen stays black. The fan might spin, the keyboard might light up, but nothing comes up. Before you assume the worst, work through these fixes in order. Most wake failures are a settings glitch, a stuck peripheral, or a battery that needs a hard reset — not a dead logic board.
First: is it really asleep, or is it off?
Listen and look for signs of life. A sleeping-but-stuck Mac usually has a faint fan or drive sound, a warm chassis, or a keyboard backlight that flickers when you tap a key. A totally dark, silent, cold Mac may have shut down or run out of battery — in that case, work through our MacBook won’t turn on guide instead. If you can hear it running but the screen is black, keep going here.
Step 1 — Force a wake with the right keys
Do not just tap a random key once. Press and hold the Power button (Touch ID key on newer models) for one second, then release. If nothing, press it once firmly. On a MacBook with a physical power/Touch ID key, a single deliberate press is the correct wake signal — repeated frantic taps can register as a shutdown request.
Step 2 — Rule out a dark screen (brightness & display)
The Mac may already be awake with the backlight at zero. Press the increase-brightness key (F2 / the sun icon) several times. Connect an external display if you have one — if the external shows your desktop but the built-in stays black, it’s a display or backlight issue, not a wake failure. See brightness won’t change for that path.
Step 3 — Force-restart (the fix for most stuck wakes)
Hold the Power button for about 10 seconds until the Mac fully powers off, then press it once to boot. This clears a hung resume — the single most common cause of a MacBook that won’t wake. If you have to do this every morning, keep reading; a repeating force-restart points to Step 5 or 6.
Step 4 — Reset the SMC (Intel MacBooks only)
The System Management Controller governs power, sleep, and battery. On Intel Macs a reset fixes chronic wake failures. On a T2 Intel laptop: shut down, then hold Control + Option (left) + Shift (right) for 7 seconds, add the Power button for 7 more, release all, then boot. Apple Silicon (M1/M2/M3) Macs have no SMC — a simple shutdown and restart does the same job, so skip this step on them.
Step 5 — Kill the peripheral that’s confusing sleep
A flaky USB hub, dock, external drive, or Bluetooth mouse can hold the Mac in a half-awake state where the display never comes back. Unplug everything, remove the dock, and try waking on battery alone. If it wakes clean, reconnect devices one at a time to find the culprit.
Step 6 — Fix the sleep settings that cause it
Open System Settings > Battery (or Energy Saver). Turn off “Wake for network access” and “Power Nap” — both let the Mac half-wake and then fail to show the display. In Displays, make sure the machine isn’t set to sleep the screen far faster than the system, which can look like a wake failure. If your Mac keeps waking up on its own instead, that’s the opposite problem — see MacBook won’t sleep or keeps waking.
Step 7 — Boot into Safe Mode & check for updates
A macOS bug or a login-item app that grabs a power assertion can break wake. Boot into Safe Mode (Apple Silicon: hold Power at boot > select drive > hold Shift > “Continue in Safe Mode”. Intel: hold Shift at boot). If it wakes normally in Safe Mode, a third-party app or extension is the cause. Then install any pending macOS update — Apple has patched several sleep/wake regressions.
When it really is hardware
If none of the above works — especially on a 2016–2019 MacBook Pro, where “sleep death” was a documented plague — the cause may be a failing battery that can’t hold the machine through sleep, a display flex cable, or (rarely) the logic board. A worn battery is a cheap fix; a board is not. Apple can charge up to $500 for a logic-board repair on a Mac that’s worth barely more than that.
If a repair costs more than the Mac is worth, replacing it is the smarter move. A refurbished M1 MacBook Air starts at $569.99, an M2 Air at $974.99, and an M1 Pro 14-inch at $899.99 — all wake instantly and carry a 1-year warranty.

Frequently asked questions
Why won’t my MacBook wake from sleep? The most common causes are a hung resume (fixed by a 10-second force-restart), a peripheral holding it half-awake, a “Wake for network access”/Power Nap setting, a failing battery, or on older Intel models an SMC glitch. Work Steps 1–6 above in order before assuming hardware.
I have to force-restart it every morning to wake it — is that bad? It won’t damage the Mac, but a repeating force-restart means a setting or the battery is the real cause. Turn off Power Nap and Wake for network access (Step 6), and if it persists, have the battery health checked.
My MacBook opens to a black screen but I can hear it running — is it dead? Usually not. That’s the classic stuck-wake signature. Force-restart (Step 3) almost always brings it back. If it recurs constantly, suspect the battery or, on 2016–2019 Pros, sleep-death.
Do M1/M2/M3 MacBooks have an SMC to reset? No. Apple Silicon Macs manage power differently — a full shutdown and restart replaces the SMC reset entirely. Only Intel MacBooks have an SMC.
