Troubleshooting Sleep and Wake Issues on Intel NUC





If you're experiencing issues with sleep, hibernate, and wake on your Intel® NUC, we recommend you first:

BIOS and graphics drivers are available on Download Center.
Refer to the table below for additional troubleshooting tips and useful information.

What are you seeing? Information / how to fix it
The Intel NUC doesn't wake up when setting it to wake at a certain time, using the Wake System From S5 option in BIOS. This can happen for the following reasons: Windows* Fast Startup is enabled. See Intel® NUC Doesn't Wake Up When Scheduled for more information.

Fast Boot in BIOS is enabled. See Using Fast Boot in Intel® Visual BIOS for more information.

Infrared remote control or USB device doesn't wake up the Intel NUC. See Remote Control or USB Device Doesn't Wake Up the Intel® NUC.
Wake-on-LAN doesn't work with ESXi installed on NUC8i7BE, NUC8i5BE, or NUC8i3BE. The NUC8ixBE family of NUCs uses the Intel I219V Gigabit Ethernet Controller. Intel provides reference drivers to VMware*, which VMware then customizes to include their software.

Please contact VMware for availability of an updated Ethernet driver.

Note Earlier versions of the I219V Ethernet controller on other Intel NUC models have VMware Ethernet drivers that allow WOL to work.


If the system is not waking when expected:

  1. Find the most recent wake event and any scheduled wake events

    1. Click the Start button and type Command Prompt. Right-click the Command Prompt listing and select Run as administrator.
    2. Type powercfg -lastwake and press enter.
    3. Type powercfg -waketimers and press enter.

      Look for keywords in the results from those two commands and try searching the internet for assistance.
  2. Check the Windows event log for wake events.  Do this right before letting the system sleep (see screenshot below for location of the options mentioned in the instructions)
    1. Click Start and type Event Viewer
    2. When it loads, click Clear Log in the right pane. Select Clear Log again when prompted.
    3. After the system has woken from sleep unexpectedly, go back to the Event Viewer and click Windows Logs on the left-most folder structure, and then select System.
    4. Look through the events for Power – Troubleshooter items and look at the details.  This should tell you what woke the system up.
