Just received the new E6500 LCD cover and trying to play around. Encountered some obstacles, managed to overcome them but at the end....
1) LCD cable connector is not the same between M4400 and E6500. I overcome this by swapping the cable. This cable shares with camara & mic cable too.
2) The cover latch is not the same. It took me 1 hour but finally still manage to overcome this by doing some minor damages on E6500 side.
3) When I thought everything is done and ready to install the LCD panel, i am doomed... the cover size is not the same between them. omg... I donno how to overcome this now. The panel simply doesn't fit on the screw holes! (vertically). And the LCD frame cover will not fit either.
Well what I can think of now maybe buying the complete set of E6500 LCD and replace the M4400 one. But this will definitely more expensive, and the cover will be larger then the bottom by 6mm. I am not sure if the latch will fit either.
