Thanks Helen, unfortunately those settings are already set to stay on all the time. I am currently investigating the following fix:
This changes a value in the registry and indicates my problem is linked to the fact that the compute stick is not connected to a monitor when the html lead appears to be not connected - i.e. the TV is off.
Could you please tell me the model of your TV?
Some TVs set automatically in sleep mode; this could be a possibility in this case. Please check your TV’s sleep settings, this can also affect the behavior of the Intel® Compute Stick.

On the other side, it is very possible that the Operating System is taking care of the power management, please see the following recommendation below, keep in mind that this suggestion is Windows Generic, you may need to look for the options that apply to your device and settings.
1- Open the advanced options in Windows by holding the Windows key on your keyboard and the letter X. Select the RUN option.
2- Type GPEDIT.MSC and click OK.
3- In the Local Group Policy Editor, go to Computer Configuration > Administrative Templates > System > Power Management > Sleep settings.
4- In sleep settings find the Allow applications to prevent automatic sleep.
5- Now click the Enabled button, then click Apply and OK.
6- Now find the Turn on the ability for applications to prevent sleep transition field, go to Edit policy setting, then select Enabled and then Apply and OK.
7- Close the group policy editor, hold down the Windows key and the letter X as we did in the beginning and open Run. Then type REGEDIT into the run field and click OK.
8- Once in the registry editor we need to navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power.
9- Inside the power folder click on HibernatedEnabled to edit the field. Change the value from 1 to 0 and click OK. Do the same for the HiberfileSizePercent field as well.
