I purchased a Lenovo Ideapad 1i - I had a Lenovo Ideapad 3 previously but felt I needed an up to date one witha better load time and able to handle several pages at once! So I bought this Lenovo and purrhased it from Amazon - As I started to use it, I found that it freezes up often when Using Excel - It seems to be too much for this laptop - I spent over $400 on sale, supposedly it was a good computer - Again, when I am using MS Excel, it freezes up pretty regularly - I lose content and it is very aggravating anf frustrating! I do not recommend this computer to anyone using Excel! I am now stuck with it until I can figure something out!
