Help me get a new laptop for school

I really need help on getting a new laptop for school. I'm pursuing the dream of being a Software Engineer and obviously taking a course to it, but because of poverty I can't buy one. A laptop is highly required in for me to get to it. You don't how much it helps to me if this gets completed. A couple of dollars means a very lot to me, and I would also be very happy too. Specially we are in Philippines where some dollars converted to our currency is very big, so i'm only asking $251 because it's already enough for me to buy a good laptop able to live until I finish my education, hopefully. Thank you very much in advance :)
