How to fix a laptop that won't wake up from sleep or hibernation mode

Summary

This guide helps you troubleshoot and resolve: How to fix a laptop that won't wake up from sleep or hibernation mode. Follow the steps below to fix the issue.

Common Causes

When a laptop refuses to wake from sleep or hibernation, the cause is usually related to power settings, outdated drivers, or peripheral devices preventing the system from resuming properly. This guide walks you through the most effective fixes for both Windows and macOS laptops, starting with the quickest solutions and moving to more detailed troubleshooting.

Quick Fix Steps

Before diving into detailed configuration changes, try these common remedies:

1. Press the power button once briefly. Holding it down forces a hard shutdown, which can cause data loss. A single short press often triggers the wake sequence.
2. Move the mouse or tap a key on the keyboard. Some laptops ignore these inputs when the lid has been closed for an extended period.
3. Connect the charger. A depleted battery can prevent the laptop from waking. Plugging in mains power often resolves this.
4. Disconnect all USB devices and external displays. A faulty peripheral can block the resume process. Unplug everything, then try waking again.
5. Close and reopen the lid. If the lid switch is misbehaving, this can reset it.

Detailed Instructions

Windows 10 and Windows 11

Disable Fast Startup

Fast Startup can interfere with normal sleep and hibernation behaviour. Disabling it forces a clean shutdown and resume cycle.

1. Open Control Panel and select Power Options.
2. Click Choose what the power buttons do from the left-hand menu.
3. Click Change settings that are currently unavailable.
4. Under Shutdown settings, untick Turn on fast startup (recommended).

Reset Power Settings to Default

1. Press Win + X and select Terminal (Admin) or Windows PowerShell (Admin).
2. Type powercfg -restoredefaultschemes and press Enter.
3. Restart the laptop and test sleep and wake behaviour.

Update or Roll Back the Display and Chipset Drivers

Outdated or corrupted drivers are one of the most common causes of wake failures, particularly after a Windows update.

1. Right-click Start and select Device Manager.
2. Expand Display adapters, right-click your GPU, and choose Update driver.
3. Repeat for System devices, particularly the chipset and Intel Management Engine entries.
4. If the issue started after a recent update, right-click the device, choose Properties, then the Driver tab, and click Roll Back Driver.

Disable Hybrid Sleep and Adjust Lid Close Behaviour

1. Open Settings then go to System then Power & battery.
2. Click the arrow next to the active power plan to expand advanced settings.
3. Set When plugged in, PC goes to sleep after to Never temporarily while testing.

Run the Power Troubleshooter

1. Press Win + I to open Settings.
2. Go to System then Troubleshoot then Other troubleshooters.
3. Locate Power and click Run.
4. Apply any recommended fixes and restart.

Update BIOS or UEFI Firmware

Outdated firmware can cause sleep and wake issues, particularly on newer laptops. Check your manufacturer's support site for the latest BIOS or UEFI update and follow their installation instructions carefully.

macOS (Apple Silicon and Intel)

Reset the System Management Controller (Intel Macs Only)

On Intel-based MacBooks, the SMC handles sleep and wake functions. Resetting it can resolve persistent issues.

1. Shut down the Mac completely.
2. Press and hold Shift (left side), Control (left side), and Option (left side) along with the power button for 10 seconds.
3. Release all keys, then press the power button to start the Mac.

Reset NVRAM or PRAM (Intel Macs Only)

1. Shut down the Mac.
2. Press the power button, then immediately hold Option + Command + P + R for about 20 seconds.
3. Release the keys when the Mac restarts or you hear the second startup chime.

Disable Power Nap

1. Open System Settings (or System Preferences on older macOS).
2. Go to Battery then Power Adapter (or Options on older versions).
3. Toggle off Wake for network access and Enable Power Nap.
4. Test sleep and wake behaviour.

Check for macOS and Firmware Updates

1. Open System Settings then Software Update.
2. Install any pending macOS updates and firmware updates.
3. Restart and test the issue.

Troubleshooting

Laptop Wakes but Screen Stays Black

This usually indicates a graphics driver issue rather than a power management fault.

• Press Windows + Ctrl + Shift + B on Windows to reset the graphics driver. The screen should flash and recover.
• On a Mac, try pressing Command + Option + P + R during startup to reset NVRAM (Intel only).
• If an external monitor is connected, disconnect it and try the built-in display alone.

Laptop Wakes Immediately After Sleep

A scheduled task or peripheral is waking the laptop unintentionally.

Windows

1. Open Command Prompt as Administrator.
2. Type powercfg -lastwake to identify what woke the device.
3. Type powercfg -waketimers to view scheduled wake timers.
4. Disable unnecessary timers in Task Scheduler under the Conditions tab of each task.

macOS

• Open Console (found via Spotlight) and search for Wake to identify the cause.
• Disable Allow Bluetooth devices to wake this computer in System Settings then Bluetooth.
• Check Energy Saver settings for Wake for network access.

Lid Close Does Not Trigger Sleep

If closing the lid leaves the laptop running, the lid switch or settings need attention.

• Confirm the lid close action is set to Sleep in Windows power settings or Sleep in macOS Battery settings.
• Inspect the lid for damage, debris, or magnetic accessories sitting against the sensor.
• On Windows, run powercfg -availablesleepstates to confirm the system supports the sleep states you expect.
• Reset the laptop by shutting it down completely, waiting 30 seconds, then restarting before testing the lid switch again.

Laptop Will Not Enter Sleep Mode

If the laptop refuses to sleep at all, background activity may be keeping it awake.

• On Windows, run powercfg -requests to see which processes or drivers are blocking sleep, then address each entry.
• Close any applications performing large downloads, backups, or updates before attempting sleep.
• On macOS, check Activity Monitor for processes with high energy impact and quit any that are unnecessary.

If the issue persists after completing all of the steps above, contact your IT support team with a summary of the troubleshooting you have already performed.
