My gaming laptop won’t turn on

Every time I click the power on button it stays off and the keyboard light won’t even turn on and before it started to doing this it was working perfectly fine it just stared to do this a few hours ago, and right before it started doing this it was on a update but I was in a rush so I had to close my laptop pretty stupid of me but now I have no clue what to do I’ve tried holding it down for long and longer and im kinda new to pcs and gaming laptops so it’s pretty confusing for me
