I currently have a Asus UL50VS, basically zero issues and it really does have a great build quality. So instead of just buying a new one, I was wondering if it can be upgraded. Right now I only have 4 GB of RAM, so putting 8 GB shouldn't be an issue. However, my main concern is the processor which is the Intel SU7300, it's in a pretty dire need of an upgrade. Is there any information that will let me know what processors are compatible with this laptop?
