What you see
- Black screen on power-on or remote access attempt
- No video on an external monitor

Why it happens
Likely The original laptop was not POSTing, so this was treated as a hardware/boot failure rather than a Windows issue; the exact root cause was not established.
When it shows up

You are in this case if:
