Windows 10: Laptop reboots instead of waking up from sleep mode

I've seen lots of power/sleep problems discussed on forums, but nothing exactly like the problem I'm having since the latest Windows 10 update.


The laptop seems to go to sleep fine. Then when I open the lid or press the power button to wake it up, it makes the unmistakable click that I always hear when it powers down (like if I hold down the power button to do a hard shut down, for example). Then it immediately restarts. Annoying because it takes a long time to warm up.


The troubleshooter doesn't show up any problems. I've tried all combinations of hibernate and hybrid sleep off and on.

Computer reboots instead of wakes from sleep

This made no difference. Upon trying to wake the computer, it goes into BIOS. The Windows boot drive is absent in the BIOS boot order list, so I have to turn the computer off, then reboot. Upon booting, any windows that were open prior to sleep are now
closed (i.e., it is a cold boot, not a wake from sleep).

 

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.
