How to Disassemble a Sony VAIO VGN-AR61ZU Laptop
How to disassemble (at least partially) a Sony VAIO VGN-AR61ZU laptop in order to replace the RAM, the optical drive and the hard disk drives.
Optical Drive - Blu Ray Disc (tm)
Hard Disk Drives
It is possible to upgrade both hard disk drives with HDDs of a higher capacity and 12.00mm height.
I have also tried to get access to the keyboard, but this doesn't seem easy, at least not at first glance. I guess you have to disassembly the notebook completely to replace the keyboard.
