PC Shutdown

Question

When I shutdown my PC, the screen goes blank promptly, but it takes half an hour or more for the disk activity to stop - it used to take less than a minute.

I have tried the following to no avail:

• performed a clean boot
• run the system file checker
• Reindexed my files
• Turned Sleep and Hibernate options off

Why does it take SO long? What can I do?

Answer 1

Hi,

Thanks, I checked there is no known issue with the model.

One issue is that your device uses a Hard disk, which is very slow compared to an SSD.

Apologies for the inconvenience caused to you.

I think this might have to do with a failing hard disk, let us clear our doubt.

Please download and run HDTune Trial or HD Tune Free.

Select the Disk where OS is installed.

Post back the screenshots.

Answer 2

I have checked the Registry Editor and it is set to 0, so that is not the cause of the problem.

 

I disabled ALL third-party services in System Configuration and then shut down the computer. The screen went blank almost immediately, but it took 23 minutes for the disk activity to stop – so a third-party service is not the cause as all were disabled.

 

I restarted my PC, selected Safe Mode in System Configuration and Restarted the machine). I shut down from Safe Mode and the Screen and Disk took 3 minutes to finish shutting down TOGETHER – not screen first then disk. So shutting down from safe mode was significantly faster and the behaviour was different.

 

I don’t know how to “Collect a crash dump” or use debuggers, and I would need guidance to both WPR and WPA

 

Please advise further

Hi,

Please supply the following Information.

Right-click the Start button and Choose the Run option

Type in msinfo32

Press enter.

Take a screenshot of the System Summary window and post it in the next reply.

I look forward to your response and am eager to collaborate until we find a solution.

Answer 4

The long delay after the screen goes blank indicates Windows is very slow completing shutdown, not a sleep/hibernate issue. Common causes in the provided context are:

1. A service or process that does not end
2. A blocked kernel thread
3. The policy to clear the paging file at shutdown

To narrow this down:

1. Check for services that don't end
   • Start the PC in Safe Mode with third‑party services disabled.
   • Shut down from Safe Mode.
   • If shutdown is fast in Safe Mode, use the System Configuration utility and selective startup to isolate which third‑party service is blocking shutdown.
2. Check if the paging file is being cleared at shutdown
   • Open Registry Editor and navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
   • Locate ClearPageFileAtShutdown.
   • If the value is 1, the paging file is being cleared at shutdown, which can significantly delay shutdown. Setting this to 0 disables that policy and removes that delay.
3. If shutdown appears to stop responding for a very long time
   • Collect a crash dump and analyze it with debuggers to check for blocked kernel threads or drivers.
   • Look specifically for blocked threads (!mex.tl -t) and for services that are not ending.

If the delay is extreme (tens of minutes) and not caused by the paging file policy, use Windows Performance Recorder (WPR) and Windows Performance Analyzer (WPA) to record a shutdown trace and identify which component is taking so long.
