How much is my gateway laptop worth?

Im aiming to sell my own laptop yet I have no idea how much that will put it on hard.The without key is definitely missing however it still is effective.The style is MX6450, that had 80GB upon it.it even offers wifi upon it to help you use someones internet.their powered by windows 7.theres no virsuse or perhaps anything wrong about it how much don’t you think it is worth

probably $50-75 thanks to it becoming fairly weakened, small HARD DRIVE, and that deterrent from the missing major.With the crucial it’d be worth a fantastic $80.
