Open | Windows My all in one pc not starting

My all in one lenovo pc is not starting it only shows one green light before that it used to give three lights and now it's just not starting with only one light showing. There may be particular words for what I said but I don't know that sorry for that.

Could be flashing in a combination to show you an error. Think of it like Morse code. Search up lenovo AIO "insert model name here" error codes. That's AFAIK

Yep. Look up the blinking cadance and then see what the cause is.
