Want to know if I can/should upgrade laptop


Dec 21, 2012
I have an Acer Aspire 5720z with an Intel Pentium T2330 1.6ghz processor with 2 gigs of DDR2 ram 266Mhz on an Acer Nettiling motherboard v1.45. I've googled alot and read some things on TH but there is a lot of ambiguity when it comes to my laptop. I want to keep this laptop for school but it is a little slow so I was wondering if I should upgrade my CPU. I have found a few options listed here:

Also, some people say that the memory is upgradable to 4gb and some say it is not. If it is, what should I get?
