Desktop not power on

@ritikaraja84373iFixit does not charge for the number of words we are using. If you really want help to fix your computer, we would greatly appreciate it if you could at least give us the complete model number for your Lenovo Legion desktop. Then you want to tell us exactly what you have already checked and what you have already tried. We also need to know if there is any light or any other sign of life on your computer. Help us to help you!
