If Windows (I am running Win 8.1) is installed on a laptop, the Device Manager will include Power Management properties, including an option to allow the computer to turn off this device to save power. By default, this option is enabled for all devices. I wish to turn off this option for all my devices, including new devices that may appear in the system.
How can I change this option for all devices?
Backstory: this option has given me a big headache several times by turning off my laptop Wi-Fi adapter on its own whim. After the adapter was turned off, I wasn't able to manage this device (showed up as 'Unknown device') until another whim of this option turned it on. I don't want to live in constant fear of parts of my computer switching off.

to never turn off, which solved the problem. – svavil – 2016-05-10T08:33:09.193
