  If your Lenovo Desktop computer does not start when you press the power button, first ensure that the power cord is correctly connected to both the rear of the computer and a working electrical outlet. If there's a secondary power switch at the rear, make sure it's switched on. Check if the power indicator on the front is lit. Confirm that the computer voltage matches the outlet voltage for your region. Also, ensure all storage drive signal and power cables are correctly connected and that the startup storage drive is the first startup device in UEFI BIOS. In rare cases, the storage drive with the operating system might be corrupted, requiring replacement. If installed, ensure the Optane memory is present and not damaged; use diagnostic tools to check it.
