Need help opening my dell laptop

[Jadaki]

Hey there. My laptop is pretty messed up now, well just a pieace. The input for the laptop charger fell out, like i guses it broke off. Its like a squae pieace, and it was loose for a few days and when i was trying to fix it, it fell out. Right now my dad thinks he can fix it but we are trying to open the laptop cover off so we can see the part perfectly and fix it. We got all the screws off but there seems to be a screw for the middle and we cant find it. Im thinking its under the keyboard, but is it? Anyone know how to pull a Dell notebook cover off, so i can fix this problem?
