A technician is setting up a computer that was shipped. After everything is plugged in, the computer will not turn on. Which of the following should the technician do FIRST to identify the issue?

While physical damage is possible, checking the voltage setting is a more specific and common issue for a new computer that won't power on.

Searching the Internet for a solution is a general troubleshooting step but should come after performing basic, essential checks.

Referencing manufacturer's documentation is a good step but often follows initial basic checks or if specific error codes are encountered.

Many computer power supplies have a voltage selector switch (115V/230V or 120V/240V) that must be manually set to match the local electrical grid. If a computer was shipped from a region with a different voltage standard, or if the switch was accidentally moved during shipping, the computer will not power on if it's set incorrectly, making this the most crucial initial check for a new setup.
