How to remove the whole LCD panel in a laptop?

Okay so this is what happened… My younger brother was playing DOTA on my laptop ( Lenovo y500 ) and then raged and he punched my laptop s screen and it cracked and only the top-left of the screen is seen and the rest of it is like some kind of vertical lines (none of the liquid is leaking out though) … I ordered a monitor from Amazon and for the time being I'm using my laptop by concerning to the TV via a hdmi cable… So my plan for now is to remove the whole screen panel and connect the rest of it to my monitor… So how do I remove it? I don't prefer screen replacement because it's much much more costly… Thanks in advance

Added (1). I meant to make my laptop into half laptop and half desktop ie the CPU is the remaining part of my laptop and the monitor connected

Search for "lenovo y500 replace screen" on Google. There are tutorials.
Just follow the steps until the screen is removed. Then you'll need to make sure your computer is protected from dust and water ingress.

If you remove the screen altogether, you may find your laptop never boots…
