My IdeaPad, suddenly will not turn on. Pressing the Power button, a led on the button is white for about 4 seconds and then turns off. I experience the same if it's running on battery or AC adapter.
The led next to the AC adapter is white when the USB C charging cable is attached.
I've tried holding down the Power button for +15 seconds with and without the AC adapter attached.
Any ideas for further troubleshooting before returning the laptop for repair?

Welcome to the Community Forums.
The hardware manual would offer steps for power system checkout (page 21-22) as it adds checking ac adapter and operational charging. The steps you have tried also adds further to suspect probable power board and motherboard issue that needs to be checked internally specially if pressing the novo button would do the same failure.
I suggest to call in tech support for service repair. You may inform them the things you have tried as I am sure it would help the repair engineers to narrow down the parts for a faster repair.
I hope this helps answer your query.
