Oh... my first recommendation would be to add some more RAM (Easiest thing to upgrade) It is possible to upgrade the processor but it depends on the socket type and where you could get a chip from. They're dear enough to buy new but if you know somebody who deals with laptops and repairs there is a chance you can get a second hand one as an upgrade. I have a few old AMD and intel noteboox processors but none of them are any good, mostly single core from old laptops I've stripped for parts.
