Question

You have been servicing a computer but when you have finished you find that it will not turn on. There was no power problem before and you have verified that the computer is connected to a working mains socket. What is the most likely explanation?

Answer 1

Step-by-step explanation:

The most likely explanation for the computer not turning on after servicing, even though it was connected to a working mains socket, is that there could be an issue with the power supply unit (PSU). The PSU is responsible for providing power to the various components of the computer, and if it is not functioning properly or has been damaged during the servicing, it can prevent the computer from turning on.

Other possible explanations could include loose or improperly connected cables, faulty motherboard, or damage to other internal components during the servicing process. However, considering that there was no power problem before and the computer was connected to a working mains socket, the PSU is the most common component to check in this scenario.
