Sony Buyer

I have a laptop sony vaio VGN-A497XP and i think the fan is not working so i want to open it. I have unscrewed everything and it comes off from the keyboard place (the upper side) but at the back near the screen, there seems to be something that does not let me open it properly. Anyone tell me if there is anything else i have to unscrew or un-clip or anything?

Thanks

the laptop is built from the bottom cover up, so you will have to dismantle the whole thing to get to the fan assembly.

have you tried using a vacuum cleaner? maybe the fan is just choked up.
