HP Elitebook 840 G8: Laptop won't start up after I opened the back

Sun, 05 Apr 2026 11:28:50 -0700

I shut my 840 G8 down. turned it over to open the back. I unscrewed the screws and gently pryed the back panel open. I pulled off the cover over the nvme ssd. All I wanted was to see how it looked like. After that I put the metal cover back over the ssd and put the back panel in place and screwed the screws in place.

After this the laptop won't start.

What can I have done?
