after removing the bottomplate you'll see the motherboard or mainboard ( in Belgium and the Netherlands we call it a motherboard.)

we will remove the connectors and cable's from the mainboard.

2th picture : in green you'll see the DC jack power connector. gently remove it.

in the same picture you see the screen connector ( in red) gently remove it.

i used a special tweezer to remove the DC jack power cable connector. like you see in the 3th picture.
