Seriously, my Sony Vaio laptop has a retarded design. Instead of having different, individual panels for the different parts of the computer, I needed to pry open the entire underside of the laptop just so that I can clean the heat sink. And this is where the problem arises: I just can't pry it open. No matter how hard I pull with my fingers or with my screwdriver, the panel won't come out.
Yes, I have made sure that I have taken every relevant screws out. I'm afraid that if I pulled harder the computer would break down.
I am very angry right now; here I am trying to take care of my computer, and it's not letting me in

. Seriously, I am trying to cool off right now; otherwise, I might end up smashing the laptop during my fit of anger, an action that I would definitely regret later on.
Anyways, sorry for the rant guys.
Should I contine pulling harder on the panel, or should I just stop for today?
