I have just managed to disassemble my amilo m7440g
First, take a screwdriver or a knife and get rid of the plastic plate above the keyboard ( on which the FuSi logo stands) where the power, wifi, etc buttons are placed. this can be easyly removed by gently pushing and turning the knife at the side of the plate. after that you can see a screw at the top of the keyboard in the middle, take that out.
now turn over the notebook!
at the bottom next to the memory modules (in the line of the LEFT ALT button) there can be found a screw which holds the keyboard. after removing that you can lift up the keyboard.
that's where I am.
I think removing the metal plate under the keyboard is the next step but I will continue it tomorrow!
I take no warranty, do it on your OWN RISK blabla
Good luck!
Matt
