In terms of hardware, you can max out the memory and add a larger hard drive, but that is about it.
What problem are you trying to solve?
It's been a year sence I bought the computer so I thought that a faster prossor would have come down to an afordable price now and I could just pop it in if I could find a compatable one. The processor I have now is an intel i5 m430 that runs at 2.27 ghz. My speccy program tells me that its the 1156 lga socket. When I look it up on intels web soight the m430 is listed as going in the bga 1288 sockit. It dosn't make sence that a company would make a mother board that couldn't be upgraded with out loosing a substantual amout of customers so I gues the question that I'm trying to figure out is why natural concequences only aply to me and never any one else?
