Windows 7 laptop is not safe if the owner did not aware for come case and make this laptop will burned. Take a look this video. Are you so smart for do this? I am not sure and not correctly sure for burn a Windows 7 laptop with reason: bored.
I am not highly recommended for do this, but if you have lots of money and want to change your laptop with high specification (like my other post), i will give your permission to burn your laptop. Why you did not give to me your "bored laptop"?
