Hi kurt1994,
If your notebook is working on the external monitor then it could be the screen or a connection. Have you contacted HP regarding this issue? If you need assistance in doing so please email me your product and contact information to psgsocialmedia@hp.com. Please inlcude Attn: Veronica-Tom in the subject line.

Have you tried pressing the FN + F4 that may be able to toggle from screen selection.

So when you turn on your laptop with the external monitor removed you just have a black screen. Try pressing the fn and f4 simultaneously a couple of times.

Your lcd screen should flash on.
