Dam buzzing noise was really starting to get to me so i decided to open this up and see what made it work.
Step one: take out all the screws on the bottom
Step two: Take the screws out from the hindges.
Step Three: Tilt lid backwards till its almost in line with the laptop
Step Four: Above the Del button there is a small hole, insert flathead screwdriver or penknife and prise it open by pushing the knife/screwdriver upward.
Step Five: Repeate the exercise for all the holes above the keyboard.
Step Six: There are 2 latches on either side of the keyboard, next to the Del and the Esc, keep lifting the pannel and eventually it will pop off.
Step Seven: Remove screws holding the keyboard in place
Step Eight: Pull keyboard out and remove the cable.
Step Nine: Remove cable for top pannel.
Thats as far as i got and i couldn't see the Choke coil.
Keyboard <--- Yes that is my toe
Pannel
With no keyboard
Where i need to get to
Where the keyboard attaches to
