In case someone decide to disassemble own laptop (upgrade or fix
something), but has no clue where to start or afraid to screw something up,
it's always a good idea to follow a proper manual.
What you could do is to look for a documentation at the website of Original
design manufacturer/Original equipment manufacturer. Two major players are
Quanta and Compal.
If someone needs a clarification about what ODM is and such, check out these
Last link, as well, provides means to find an information about the
manufacturer of your laptop, in particular.
One way to do it is to, carefully (read: close the lid, hold in both hands),
put your laptop upside down, and look for a sticker with "Model Name:",
"Rating:", etc. fields on it.
