Windows 10: Laptop always reboots when waking from Sleep mode

I have a Lenovo laptop model 81SS, running Windows 11 Enterprise which always reboots losing all open apps, etc. when waking from Sleep mode. The assigned user states that it has always done that, and she has just recently cranked up the Sleep settings to get around it, as it has gotten more prevalent. In working with it today I can consistently get it to fail, and have grabbed a filtered Event Log, and the corresponding Memory Dump. Corresponding to the failure, the attempt to wake the system occurred at about 12:50 PM, and the list of events >= Warning are as follows:I have already

ASUS Laptop Won't Wake from Sleep Mode

OS Name Microsoft Windows 10 Pro
Version 10.0.18363 Build 18363
System Manufacturer ASUSTeK COMPUTER INC.
System Model UX490UAR
System Type x64-based PC
SMBIOS Version 3.0

Problem: about 80% of the time, my laptop won't wake up from sleep mode via keyboard press or mouse move/click. I seem to be missing many common features in power plan too, even after fresh Windows 10 install.

Troubleshooting Steps:

1. Reinstalled Windows 10 (clean)
2. Updated all drivers
3. Replicated on multiple Windows 10 versions, updates
4. BIOS latest version
5. No USB devices attached, ever. Only USB-C power and bluetooth mouse
6. Disabled "fast startup" in control panel

 

Waking PC up from sleep mode causes a reboot

Problem:





I have a small group of Dell Latitude E7470 (Bios Version 1.11.3) laptops that have and sleep mode issue.





When a user closes the top cover of the laptop and puts the machine to sleep all appears normal and the power light begins to pulse. Then, when the user opens the top cover to begin using the laptop
once again the laptop fails to wake up from sleep mode and restarts causing the user to log into the laptop each time. The laptop behaves this way regardless of the way it entered sleep mode, e.g. via the power button or from the start menu.

• The laptop power settings are defined by group policy.
  
• All of the affected laptops are running Windows 10 1809 Enterprise.
  
• The issue does not appear to be a user problem as the issue occurs whether or not a user signs into the laptop.
  
• The bios was updated prior to imaging the laptop in the spring of 2017. v1.11.3
  

Troubleshooting:





The following steps have had limited success.

• Bluetooth on/off. Sometimes if we leave the Bluetooth off the issue goes away, but not always.
  
• Changing what closing top cover does, e.g. change the setting of the top cover to do nothing when closed and then return the setting back to sleep when the top cover closes.
  
• Swapping SSD from one computer to another identical make/model computer and then back. In this step, we move the affected SSD to another laptop and boot the computer. then log in and test sleep mode.
  at this point, the issue is not present. Then, we place the SSD back into it's the original laptop, so far, this has been successful, however, we are still not confident this is a long term fix and we would like to understand why this step would have the
  effect that it does.
