Summary: PC won't sleep, wakes instantly, or hibernate is missing? Fix power plans, wake timers, fast startup, and drivers that block sleep on Windows 11.
Recommended app: PC-Troubleshooter — https://www.mytechnician.tech/apps/windows-troubleshooter/ (Microsoft Store: https://apps.microsoft.com/detail/9N7RWKW8SP24?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## The Problem
You close the lid or choose **Sleep**, but the fans keep spinning, the screen never turns off, or the PC wakes five seconds later. Hibernate may be missing from the power menu entirely. Sleep issues are usually a wake timer, **Fast Startup**, or a device/driver that refuses to release the system—not a failing power supply.

> **PC won't shut down or restart at all?** That is a different fix: [Windows 11 not shutting down or restarting](https://www.mytechnician.tech/tips/fix-windows-11-not-shutting-down-restarting/). **Battery drains while supposedly asleep?** See [laptop battery draining fast](https://www.mytechnician.tech/tips/fix-laptop-battery-draining-fast-windows-11/).

## Symptoms
* **Sleep** option is grayed out or missing from Start → Power.
* Lid close does nothing; display stays on.
* PC sleeps but wakes on its own overnight—keyboard LED blinks, fans ramp up.

## The Fix: Step-by-Step

### Step 1: Set What Closing the Lid Does
1. **Settings** → **System** → **Power** (or **Power & battery**).
2. Expand **Screen and sleep** — set **When plugged in, put my device to sleep after** to your preferred time (e.g. 15 minutes).
3. On laptops: **Control Panel** → **Hardware and Sound** → **Power Options** → **Choose what closing the lid does** → set **When I close the lid** to **Sleep** for both plugged in and on battery.

### Step 2: Turn Off Fast Startup
Fast Startup can break sleep and hibernate on some hardware.
1. **Control Panel** → **Power Options** → **Choose what the power buttons do**.
2. Click **Change settings that are currently unavailable**.
3. Uncheck **Turn on fast startup (recommended)** → **Save changes**.
4. Reboot and test sleep.

### Step 3: Find What Is Waking the PC
1. Open **Terminal (Admin)** and run:
   ```cmd
   powercfg /lastwake
   powercfg /waketimers
   powercfg /devicequery wake_armed
   ```
2. Note the device or scheduled task listed—common culprits: **Intel(R) Ethernet**, **HID-compliant mouse**, **Scheduled Task**, **Wake Timer**.

### Step 4: Disable Wake on LAN and Peripherals
1. **Device Manager** → expand **Network adapters** → right-click your adapter → **Properties** → **Power Management** → uncheck **Allow this device to wake the computer**.
2. Repeat for **Mice and other pointing devices** and **Keyboards** if you do not need wake-from-keyboard.
3. Run `powercfg -deviceenablewake "Device Name"` only when you want to re-enable a specific device.

### Step 5: Enable Hibernate (If Missing)
1. Open **Terminal (Admin)** and run:
   ```cmd
   powercfg /hibernate on
   ```
2. **Settings** → **System** → **Power** → **Screen and sleep** — **Hibernate** should appear in Start → Power after a reboot.

### Step 6: Restore Default Power Plan
1. **Control Panel** → **Power Options**.
2. Select **Balanced** (or **Power saver** on laptops) → **Change plan settings** → **Restore default settings for this plan**.
3. Click **Change advanced power settings** → **Sleep** → **Allow hybrid sleep** → **Off** (test); **USB selective suspend** → **Disabled** if USB devices block sleep.

### Step 7: Update Chipset and Graphics Drivers
Outdated chipset or GPU drivers are a top cause of instant wake.
1. Update from your laptop maker's support site or motherboard vendor—not a generic driver pack.
2. See [how to update PC drivers safely](https://www.mytechnician.tech/tips/how-to-update-outdated-drivers/).

## Still Not Working?
* **Desktop never sleeps—only display turns off?** A background app may be holding an audio or presentation API open. Close browsers, media players, and meeting apps, then test.
* **Sleep works on battery but not plugged in?** Compare both power plans in **Control Panel** → **Power Options**—they often have different sleep timers.
