That's where you went wrong mate. If you want your computer to sleep allow it turn the device off. If you don't the USB and other devices will prevent the computer from going to sleep cause the devices are in use by the computer cause you said "nope i don't want the computer to shut you guys off".
Hi EricFrendo-Cumbo,
thanks for the explanation.
I have gone back into the device manager and for every single device that has a power tab in its properties, I have now Checked both the box for both "Allow the computer to turn off this device to save power".
Still no sleep :-[
Is there anything else I can try ???
If you run 'powercfg /devicequery wake_programmable' from an administrator command prompt, you will probably see one or more network adapters named something like 'Intel(R) I211 Gigabit Network Connection' or 'Intel(R) Wi-Fi 6 AX200 160MHz'. Try using 'powercfg /devicedisablewake <devicename>' to disable wake for each one. In my experience, wake-on-LAN is enabled by default for all network adapters, and any network with other devices on it will constantly wake your device from sleep unless you're in a carefully configured workplace where everything is hooked up to switches.
