Laptop has black screen

My laptop was closed and now will not wake up. I’ve tried all the steps I found online and still nothing. Any suggestions??

Welcome to HP Community!

Here's what you need to do, to identify the issue and resolve it accordingly:

• check if it works fine on an alternate/external monitor.
  • If it works fine on an alternate screen, please Perform a hard reset, Attempt a BIOS recovery  and then, Run the System Diagnostics tests.

I've tried all those steps with the exception of the memory module because I cannot get the back off the laptop
