MacOS Sequoia waking from sleep automatically

Since upgrading to MacOS Sequoia every time I set the Mac to sleep it automatically wakes. So the computer is basically on the whole time. I have set the machine to power off after 2mins and it still wakes. Please help.

MacBook Pro 13″, macOS 15.0

Is it waking when a Notification comes in or is there an App that is preventing it from sleeping. To check if it is an App, open Activity Monitor in your Utilities folder and choose the Energy tab. The column on the right called "Preventing Sleep" will identify any apps that will not allow your computer to sleep.

  • What displays are we working with?
    • A BenQ GW2765 display. If I unplug it, sleep and hard disk is fine and screen goes to black as expected. Just not whilst its connected.
  • What are your settings that affect Display sleep at  > System Settings > Lock Screen?
    • Start screen saver when inactive - 2mins
    • turn display off on battery when inactive - 2mins
    • turn displays off on power adapter when inactive - 5mins
  • What are your settings at  > System Settings > Battery >Options?
    • slightly dimm the display on battery - on
    • prevent automatic sleeping on power adapter when the display is off - off
  • Are there any third party settings for your displays?
    • not that I'm aware of
  • Are you manually putting it to sleep or letting it automatically sleep after a period of time?
    • either
