Re: hp mini cpu/computer chip
you won't be able to. You might be able to upgrade the processor, but it wouldn't give you a lot of increased performance and upgrading the motherboard is out of the question. The goal of a netbook remember is mobility, not power. If the mini isn't enough performance for your needs then I'd look at getting a laptop.
A notice to EVERYONE who has posted here with a computer problem, I highly encourage you to keep current with the forums, even if it's browsing for 10-15 minutes during lunch, or before you go to bed at night. There are many things that you can learn and apply to future issues. My goal is to help people get to a point where they can use their own knowledge to help themselves, and others.
