Windows 11 does not wake from sleep or immediately sleeps again
What to do first
If the PC cannot wake, try supported actions including the power button, then check screen and sleep times, external devices, and Windows and manufacturer updates.
This is a general troubleshooting guide, not an announcement of a current outage.
Affected products and symptoms
- Product
- Windows 11 Power and Sleep
- Versions and conditions
- Windows 11
Symptoms
- Keys or the mouse cannot wake the PC
- The screen is black after waking
- The PC unexpectedly returns to sleep immediately
Causes and conditions
The wake method supported by input devices, screen and sleep timeouts, external devices, pending updates, or display and chipset drivers may be involved.
Before you start
- Check autosave because unsaved data could be lost
- Record whether the issue occurs on battery or while plugged in
- List connected docks and USB devices
Precautions
- Do not use a long power-button press as a normal wake action because it loses unsaved data
- Do not turn off power during a BIOS/UEFI update
- Do not change corporate PC power policies without authorization

Step-by-step instructions
Try a keyboard key, a mouse click, and opening the laptop lid. Some models do not wake from input devices, so briefly press the power button once. Avoid holding it down, which forces a shutdown.
First check whether the USB mouse or keyboard is switched off or has depleted batteries. When using the power button, press it briefly once and wait a few seconds. Distinguish this wake action from holding it down to force a shutdown, which loses unsaved data.
If the PC's lights or sounds are active but the screen alone is black, press Windows key+Ctrl+Shift+B once to reinitialize the display driver. If using an external monitor, also check the projection destination with Windows key+P.
Open Settings > System > Power & battery > Screen, sleep & hibernate timeouts. Check plugged-in and battery settings separately, and use a value longer than a few minutes while testing.
Before changing anything for testing, note both the screen-off and sleep times. Turning off only the screen is different from putting the PC to sleep. If testing while plugged in, change the AC-power setting instead of changing only the battery setting.

Safely disconnect docks, USB storage, external displays, and unnecessary USB devices, then try reproducing the issue once using Start > Power > Sleep. If it improves, reconnect devices one at a time to identify the one involved.
Save files before trying manual sleep. After waking, reconnect one removed device and test again, recording which device makes the issue return. After testing, restore the normal timeout values changed in step 3.
Complete Settings > Windows Update and restart. If the issue continues, check the PC manufacturer's official Windows 11-compatible BIOS/UEFI, chipset, and graphics updates. If using BitLocker, verify the recovery key before updating firmware.
Check the result
- The PC sleeps from the Start menu and wakes with a brief power-button press
- It does not unexpectedly sleep before the configured time
- The issue does not recur after reconnecting devices, or the responsible device is identified
If the problem continues
- If every occurrence requires a forced shutdown, temporarily stop using sleep and give the PC manufacturer the model, update version, and reproduction steps
- If only the external monitor fails to return, troubleshoot using the external-monitor connection procedure
Scope of this guide
Troubleshooting guide — Ensure that the PC sleeps at the configured time and wakes using the power button or supported input without losing data.
Frequently asked questions
Does failing to wake with the mouse indicate a fault?
Some models or connection methods do not support mouse wake. First check whether a brief power-button press wakes the PC.
Can I hold the power button every time the screen is black?
Holding it forces a shutdown. First try a brief press, display-driver reinitialization, and the external display's projection destination. If the issue repeats, proceed to manufacturer diagnostics.
