Task 4: Apply fault remedies safely to simple (easily identifiable) IT system problem. (P4, P5, P6)

Machine does not power on.

The first step would be to check if the button on the back of the device is switched on. If it’s off then you have to turn it on in order for the machine to start working make sure you turn all the buttons on. Buttons such as:  Power button/switch on the front of the computer, Power switch on the back of the computer, Power switch on the power strip, surge protector, or UPS.  Find out that the power supply voltage switch is set correctly. If the input voltage for the power supply does not match the correct setting for your country the machine may not power on at all. Most importantly you have to check for disconnected computer power cable connections. Replace the computer's power cable. If your computer is no working power supply unit you should test whether the (PSU)  should be replaced. You should however test it just to be sure. The computer fault could also be that the power on and off button on the back of the computer is not working. This is not usual case but it could happen in this case the power button should be replaced. In worst scenario the problem might be on the motherboard in this case motherboard should be replaced.
