Have you ever configured your Windows laptop to sleep after a few minutes of inactivity, only to find the screen never turns off?
I recently ran into this issue on my Dell Inspiron 16 running Windows 11 Pro, and after hours of troubleshooting, I discovered the culprit wasn't Windows itself—it was an application using Microsoft Edge WebView2.
Here's how I diagnosed and fixed it.
🖥️ The Problem
My power settings were configured correctly:
- Display turns off after 3 minutes
- Sleep after 3 minutes
- Hibernate enabled
Despite that, the laptop would remain awake indefinitely. The display never turned off, and the system never entered sleep.
🔍 Step 1: Check for Power Requests
Windows includes a built-in command that tells you what's preventing your computer from sleeping.
Open Command Prompt as Administrator and run:
powercfg /requests
The output looked something like this:
DISPLAY:
[PROCESS] msedgewebview2.exe
Video Wake Lock
The important part was Video Wake Lock.
A Video Wake Lock tells Windows that media playback is active, so Windows intentionally keeps the display awake.
🔎 Step 2: Find Which Application Owns WebView2
Many Windows applications use Microsoft Edge WebView2, so simply seeing msedgewebview2.exe doesn't tell you which application is responsible.
I used PowerShell to identify the parent process for each WebView2 instance:
Get-CimInstance Win32_Process |
Where-Object {$_.Name -eq "msedgewebview2.exe"} |
Select-Object ProcessId, ParentProcessId,
@{
Name="Host"
Expression={
(Get-CimInstance Win32_Process -Filter "ProcessId=$($_.ParentProcessId)").Name
}
} | Sort-Object Host
The output revealed several applications using WebView2:
- Widgets.exe
- Microsoft Teams
- SearchHost.exe
- Visual Studio (
devenv.exe) - PCAppStore.exe
At this point I still didn't know which one was preventing sleep.
🧪 Step 3: Eliminate Processes One by One
I terminated each host process individually and checked the power requests again.
Stop-Process -Id <PID> -Force
After each process was stopped, I reran:
powercfg /requests
When I terminated PCAppStore.exe, the output immediately changed to:
DISPLAY:
None.
🎉 That was the smoking gun.
PCAppStore.exe was holding a Video Wake Lock through WebView2, preventing Windows from turning off the display or entering sleep.
💻 Step 4: Verify Sleep Support
To ensure there wasn't a hardware limitation, I checked the supported sleep states:
powercfg /a
The output showed:
Standby (S0 Low Power Idle)
Hibernate
This means the laptop uses Modern Standby (S0) rather than the traditional S3 Sleep.
Modern Standby is more sensitive to applications requesting wake locks, making powercfg /requests an essential troubleshooting tool.
✅ Step 5: Fix the Root Cause
Once I identified the offending application, the fix was straightforward:
- Disable the application from Startup
- Close it when not needed
- Uninstall it if you never use it
After preventing PCAppStore from running, my laptop finally behaved as expected:
- ✅ Display turns off after 3 minutes
- ✅ Laptop enters sleep automatically
- ✅ Wake-up works normally
🔐 Bonus: Require a PIN After Sleep
After fixing sleep, I noticed another issue:
The laptop woke directly to the desktop instead of asking for my PIN.
To fix that:
Settings → Accounts → Sign-in options
Configure:
If you've been away, when should Windows require you to sign in again?
Choose the shortest available delay (or Immediately, depending on your Windows version).

💡 Lessons Learned
A few things I learned from this experience:
- Start with
powercfg /requestswhenever Windows won't sleep. -
msedgewebview2.exeis often just the messenger—you need to identify the parent application. - Modern Standby systems are more susceptible to applications holding wake locks.
- Third-party utilities can unintentionally interfere with Windows power management.
Final Thoughts
Initially, I suspected Windows, Dell firmware, or Modern Standby itself.
In reality, a background application was keeping the display awake by holding a WebView2 Video Wake Lock.
If your Windows laptop refuses to sleep despite correct power settings, don't overlook background applications.
A single process may be the only thing standing between you and a properly sleeping system.
Hopefully this saves someone else a few hours of troubleshooting.
