Need help to open an Aspire 9302WSMI

Hi, first excuse my poor english (I m french). I bought an acer aspire 9302 WSMI is june 2007, and today it s already a dead laptop. I regret that I bought this brand, they never update any driver and the after purchase service is only about making more money !

I repaired it last year for 180 euros, and it`s down again. The guy told me that it was the graphic card that was decollate from the motherboard because of the heat. When I start it there is nothing, not even a bip.
I want to replace the chipset myself with the same one from another aspire 9302 (if I can find one). But I never do that before, I removed the screws but wasn`t able to open it. If there is pictures somewhere please tell me, if you have any infos they are welcome.

Thanks.

 

if you have AMD KC.ATK02.530 CPU Athlon TK53 1.7GHz 2*256Kb , test it with an notherone Exept that one Model !!!!!!!!!!! els mainboard
to open ,, bottom screws , remove all (on the left from the frond second up 1 large screw), on the back 2x larger screws, disconnect wifi cable,remove middel cover , keyboard , lcd hinge screws (large), 3 smal screws after you remove lcd ,and your done, mainbaord has 3 screws silver

 

Thanks for your reply but it`s not enough to help me, I need photo because I don`t know how to remove the keyboard, I don`t know what is the middle cover too ! I never opened a laptop, but I know I can handle that with a photo tutorial if I can find one...

It`s the AMD Turion 64x2 TL-50 that I have.

 

lol middel cover is the cover where your powerbutten is , keyboard you can remove bij klicking the top holders (4)you can push them back begin in the middel dan pul your keyboard up from the t and y key or any
Lower cover = ware you mainboard sits in
uppercover = wat you put on top of the lower cover
middel cover = most of them wehere your power butten is
Lcd cover = the back of your lcd screen
lcd bezzel = cover thats around of you lcd that sit on top of you lcd cover
