windows 10 - PC waking from sleep for unknown reason

I recently started experiencing an issue with my PC, which runs Windows 10 Pro. It wakes from hibernation at seemingly random times. I have done the following to try and troubleshoot the issue:

• Turn off wake timers


• Disable all peripherals from waking the system


• Unplug network cable (No Wi-Fi)


• Try another power outlet

The computer still wakes at random times. When issuing the command

powercfg /lastwake

I get the following:

Wake History Count - 1
Wake History [0]
    Wake Source Count - 0

I absolutely need Wake on LAN to work on the system, and it always has before. This issue only started recently.

Answer

The issue was caused by TeamViewer, it creates wake timers that are somehow ran(?) even though wake timers are disabled. Even shutting down TeamViewer doesn't solve the issue for me. But uninstalling TeamViewer resolved the issue.
