i recently found out that the fan stopped working in my vaio laptop and as a result the whole system seems to be on a major go slow, the fan looks to be easily accessible but after removing all the screws from the base there is still something stopping me from seperating the bottom from the keypad....really frustrating as the fan is right on show but i need to part the two pieces to replace it......does anyone know why i can't seperate the two or maybe a link to a pdf repair manual?....cheers guys.
