Laptop Shuts Down Randomly When In Sleep Mode

[user-nlb]

My workplace recently bought a few HP ProBook 4 G1i 16 inch Notebook AI PC IDS Base Model laptops. I am experiencing the issue I am about to describe with only one of them. The others are working without issue.

The computer I am experiencing the issue with will go into Sleep Mode. It will randomly then decide to shut down and I then lose any work I have open prior to Sleep Mode. This issue happens whether or not the lid is closed. It appears to only happen when the laptop is unplugged from power. I tried updating drivers manually and using the HP utility to ensure I obtain the correct drivers. I have also tried reinstalling Windows 11 23H2 fresh and the issue still occurs. I ran diagnostics from the BIOS and also from within Windows, using HP Utility and they all passed. I am not sure what is causing this issue and it is starting to stump me! I've also tried turning hibernate off (using the command "powercfg -h off") and adjusting various sleep timer settings and the issue persists. I've also contacted HP Support via chat and they told me that it was an issue with things on my end and to discuss this with my system administrator (I am the sys admin). There is no bloatware and the image only has a few applications such as VLC Media Player, 7-Zip, Adobe Reader, etc. We have not experienced any issues with these programs on other computers with this same Windows Image. I've also checked Event Viewer, and I am only finding that "The Last System Shutdown was Unexpected" and I am not sure what else to look for to determine the issue. Any tips or suggestions to try would be greatly appreciated. I will update this post if I have any more information regarding the issue. Thank you for reading.

UPDATE 2/23/2026:
I found a possible solution on another thread, I will post it below for reference. I have performed the following on the laptop that is experiencing issues and will report back if the issue is resolved or not within a few weeks:

Thank you for reaching out with your concern. I'm glad to assist you today.

The issue you're experiencing where your laptop restarts unexpectedly after prolonged sleep, is typically linked to Connected Standby (Modern Standby) and power management conflicts. The Kernel-Power Event ID 41 indicates the system did not shut down cleanly, often due to a crash or power loss during sleep or wake transitions.

Let’s walk through steps to diagnose and resolve this:

Disable Modern Standby (Connected Standby)

Modern Standby, which can sometimes cause instability during long sleep periods. You can disable it to revert to traditional S3 sleep:

1. Open Command Prompt as Administrator.
2. Run this command to check if Modern Standby is enabled: 
   powercfg /a 
   If you see Standby (S0 Low Power Idle), Modern Standby is active.
3. To disable it:

• Open Registry Editor (regedit)
• Navigate to: 
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
• Create a new DWORD (32-bit) value named: PlatformAoAcOverride
• Set its value to 0. 
• Restart your laptop.

After the reboot, I went back into CMD Prompt and ran "powercfg /a" to ensure my changes took effect.

UPDATE 3/23/2026 - The steps above did not resolve my issue. Issue is still occurring. We sent the affected devices in for repair to our vendor. We'll see what happens next...

@user-nlb, Welcome to the HP Support Community. 

Thanks for reaching out about your query regarding the HP ProBook 4 G1i 16 inch Notebook AI PC.

We're thrilled to have the opportunity to assist you and provide a solution. We hope our assistance has been helpful! 

Given that the issue is occurring with only one of the HP ProBook 4 G1i laptops in your workplace, it's likely that the problem is isolated to this particular device. Here’s how you can troubleshoot and potentially resolve it:

Common Steps for Isolation and Resolution

1. Detailed Symptom Description

   • Confirm the specific issue the faulty laptop is experiencing (e.g., booting issues, display problems, connectivity errors, etc.).

2. Visual Inspection

   • Check Physical Connections: Ensure all ports and connections are secure, with no visible damage or obstructions.
   • Inspect the Hardware: Confirm there are no strange noises coming from the fan or abnormal heat emanating from the device.

3. Power and Battery Check

   • Battery Condition: Confirm that the battery is properly seated and check if the laptop functions without it when connected to the charger.
   • AC Adapter: Swap chargers with a working unit and see if the problem persists, ruling out adapter issues.

4. Software and Drivers

   • Driver Updates: Ensure all drivers are up-to-date by using HP Support Assistant or visiting the HP website.
   • Operating System Updates: Check for and install any pending Windows updates.

5. Run Diagnostics

   • Hardware Diagnostics: Use HP PC Hardware Diagnostics to perform component checks and identify faults.
   • BIOS Updates: Ensure BIOS is up to date, as newer versions can resolve hardware detection issues.

6. Reset the Device

   • Restore Settings: Reset the laptop to factory settings through Windows Recovery if the issue persists despite checking configuration.
   • Hard Reset: Perform a hard reset by turning off the laptop, removing power sources, and holding the power button for 15 seconds.

7. Test and Compare

   • Use the problem laptop under similar conditions as the functioning devices (e.g., temperature, software environment) to verify consistent operations or issues.

I hope this helps!

Take care and have an amazing day!

Thank you for your helpful tips. However, I have already tried everything you have mentioned (I am a computer tech), and sadly, these tips did not resolve my issue. We ended up sending these units in for repair. Have a great day!

We are having this exact same issue with all the HP ProBook 4 G1a 16 that we've recently purchased. Have updated every driver with what is available on HP's website but the issue remains. Laptop enters modern standby and at some point shuts down.
