I am running Unraid OS 6.12.8 on a Dell XPS 17 Notebook (Intel Quadcore), running various Dockers and a Home Assistant VM
(working perfectly fine so far).

 

However I want to minimize Energy Consumption, the machine eats on fresh boot eats approx. 70W, in that situation the Notebook Screen is still powered on. I want to put the Monitor Display to sleep, so it does not burn energy, if I achieve that energy consumption goes down significantly (down to 35-40W).

 

I am not aware of a way to power down the monitor at the moment via Unraid, however I have realized that if I put the Notebook to sleep (mem) and start it again via Wake On Lan, the machine fully available but keeps the Notebook display off of achieving the desired reduction of power consumption.

 

However, when I do this procedure it seems to cause issues with my Home Assistant VM, as it can't detect Bluetooth devices anymore with the Bluetooth Adapter (Asus BT-500) = Bluetooth Integration tries to connect to Bluetooth adapter but fails.

Strange thing is that the Bluetooth Adapter is still available in Unraid as well as in the Home Assistant Console (I can connect to it via Unraid Console as well as Home Assistant Terminal), so i am not sure what is causing the issue here.

 

To simplify my life I am looking for a way to either:

a) to deactivate the Notebook Display without the Wake on Lan workaround or

b) resolve the issue with the Bluetooth Adapter not working correctly after waking the Notebook up again.

 

My Current procedure to by pass this is as follows:

1. Deactivate Autostart of Home Assistant VM

2. Shutdown Unraid

3. Start Unraid,

4. Put to Sleep/Mem

5. Wake on Lan

6. Start Home Assistant VM

 

In this scenario everything works perfectly fine.

 

If Home Assistant Runs before putting to Sleep/Mem

a) Full Shutdown and Start of the Home Assistant VM does not solve the issue

b) Full Restart of Unraid solves the issue

 

Currently not sure how to solve it. Any tips?

Unraid will turn off display after some peroid from bootup, notebook screen never turn off ?

 

If folding notebook screen, it won't power off the monitor ?

If that, it likely power draw come from GPU instead LCD.

So I rebooted now to see if and how long it stays on. Closing the lid has no effect display is still active at the moment.

So the screen went black, but the backlight is still powered, so there is no power reduction to be seen.
