So i have an old laptop that i haven't used for long time because i have a better desktop computer but i really wanted to have a laptop too and no matter how much upgrading will cost, getting a new pc is super expensive in where i live, anyway, my old laptop is Sony VAIO vgn-n11s_w and i tried searching online for the maximum amount of ram and almost of them tell me it's 2 GB ram and this is very low in these days, so is there any way of bybassing that limit ? like upgrading my OS or the CPU, can i even replace the motherboard with another one ? (almost impossible, i know), so is there a solution to make it a decent pc or is just pointless and i'm better off selling it ?
