How old are you? if you're old enough, you should try getting a part time job, earn and save enough money to get the laptop you want. This can be as simple as mowing lawns for your neighbors or washing cars for $10 and give people a high quality car shine.
There are many ways you can earn money, and nothing beats the feeling like working for something and buying it yourself. Your mom can't stop you if it's your own money.
My cousin worked and saved 10k dollars to attend a college in England.
