| This section pulls together information regarding power management on "PCs" and "laptops". | The following is a list of common reasons why computers are left on all the time: * An external service needs access the computer e.g. backup * An individual needs to access their computer e.g. to retrieve a file while at a conference * An individual wants to avoid waiting for a computer to start up * A computer is used to keep another computer on * A computer is used to filter emails all the time * Spare computing capacity is 'donated' to science experiments Tools can be used to minimise the amount of time computers are left on without doing any useful work. Organisation will also have to decide if any practices need to change because they are too costly. |

The following is a list of common reasons why computers are left on all the time:
- An external service needs access the computer e.g. backup
- An individual needs to access their computer e.g. to retrieve a file while at a conference
- An individual wants to avoid waiting for a computer to start up
- A computer is used to keep another computer on
- A computer is used to filter emails all the time
- Spare computing capacity is 'donated' to science experiments
Tools can be used to minimise the amount of time computers are left on without doing any useful work. Organisation will also have to decide if any practices need to change because they are too costly.
