Suspend

Today it is still as common as it was in the 90s to go for a coffee after switching on the PC in the morning, only to find it still booting when coming back several minutes later. SSDs have not arrived in the average office yet, and even they can only cure some of the diseases that cause computers to start up agonizingly slowly.

Having a server at home is a great luxury, but having a computer running 24x7 is an extreme waste of energy. Turning it on and off manually is not very appealing, either. Luckily we have to do neither. Windows can easily be configured to put the computer into sleep mode (where modern PCs consume approx. 1 Watt) and have it wake up upon access.
