On the majority of computers there is a switch on the front panel which will power up the computer. Depending on the maker of your computer this switch will either be a push-button or something like a light switch. The following symbol is commonly used to indicate a power switch for most electrical equipment:

If your monitor is from the same manufacturer as your computer you will probably see a similar button/switch on the front of your monitor. Your monitor will probably have other controls on its front panel and you shouldn't mess with these unless you know what you are doing.

Turning the Computer On

In order to protect the equipment you are using, you should do the following:

1. Check that all mains cables are plugged in and laid out safely

2. Check that the mouse and keyboard are connected to the back of the computer

3. Make sure that the monitor is firmly connected to the back of the computer

4. Make sure there are no floppy disks in the floppy drive - if there are, use the button to eject them

5. If you are using equipment like scanners or printers, make sure they are connected now and turn them on.

6. Turn on the monitor

7. Turn on the computer, you should hear a beep, then wait

If nothing appears to be happening check to see if there are any lights flashing or noises coming from the computer. If there is no activity check all the power cables and try again. If your computer is making a humming noise but you can't see anything on the monitor, then make sure the monitor is turned on, and that it is plugged into the mains, and that it is connected to the computer.

Working Safely with Computers

As with all electrical equipment you should exercise care when using it. It is important to follow safe working practices when using information technology. This means avoiding risks to yourself and other users, and to the equipment. It also means keeping your information safe and secure.

Equipment:
The equipment that you are using has been designed to be as safe as possible. The computer itself and other equipment such as printers and scanners are powered from the mains electrical supply. You should take the same care as you would with any mains-powered electrical equipment.

Cables should be arranged safely. They should be laid tidily and must not be damaged.

Eating and Drinking:
Never eat or drink around IT equipment. Liquids are particularly dangerous - a spilled drink can lead to a serious electrical shock as well as causing damage to equipment.
