If you have bought a computer, you should remove the case to check if the cables are plugged into place. If there are any mistakes, it is not difficult to reconnect the cable because each cable is unique and can be distinguished by color and shape.

The power cord is not properly connected, which causes the computer to not turn on.

Verify that the power cord is properly connected to the wall outlet and to the back of the computer. If everything looks fine, unplug the power cord and re-plug both ends of the cord to make sure the cable is not loose.
