R51 disassembly

[CZOLG]

Hello everybody,

I have a question regarding disassembly of my R51.
I would like to clean the cooling system from the dust (radiator, fan etc)
I will use compressed air but I need to disassemble my Thinkpad.
I have no clue as where to start. Will it be enough if I remove the keyboard?
How do I do it?
Any suggestions and guidelines regarding disassembly would be welcome.
