I am a retired 76 yr old senior with very low income, and my computer crashed. I took it apart and tried to fix it, to no avail. I want to buy a i3 intel core, 15.6" laptop with an aluminum frame. ( Age has its clumsiness) I read somewhere there is something called a Sager, but I've never heard of it. I of course would like the ASUS or LENOVA, but they are above my budget. Any suggestions?
