Saving power

Disable Fast startup
Your computer uses Fast startup to start quickly, but also uses a small
amount of power to check for signals to start. These checks consume
extra power.
If you prefer to reduce your computer's power requirements and
environmental impact, turn off Fast startup:
Note
If Fast startup is off, your computer will take longer to start from Sleep.
Your computer will also not start if it receives an instruction to start over a
network (Wake on LAN).
