Perform a power cycle: Unplug the computer, wait a few seconds, and then plug it back in. Then press the power button to turn it on.
Check the power button: Ensure that the power button is functioning properly and that the computer is not in sleep mode.
Check the monitor: Make sure the monitor is properly connected to the computer and that the monitor’s power cable is plugged in.

Try a hard reset: Unplug the computer from the power source and press and hold the power button for at least 10 seconds. Then, plug the computer back in and try turning it on again.
Run diagnostic tests: Some computers have built-in diagnostic tools that can help you identify problems with the hardware.
