  1. 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.

    :)

    Windows 10 - Problem waking up from sleep mode

    This worked for me on a Lenovo Horizon2 27 all-in-one PC that was able to sleep manually but could not be wakened once sleeping after upgrading to Windows 10 Home.

    I ran the powercfg /energy and examined the report as GoWMike describes. It showed no driver errors but suggested that there is a problem with the system's "High Performance" power setting that may prevent normal waking from manually induced sleep.

    I used powercfg /list to show available modes, copied the GUID for Balanced mode, and then used this with the powercfg /activate command to change the plan.

    I also used powercfg /devicequery wake_from_any

    to get a list of device names for components capable of waking the system from sleep, and then I used

    powercfg /deviceenablewake <devicename>

    to make certain that the touchscreen and power button are armed to wake the machine.

    After restarting, sleep and wake then functioned properly again.
