I have a friend that just bought me a new computer, Toshiba Satellite C55-B5300. It was very nice of him to do so. However, I am afraid that he has bought something that won't help me much unless I can upgrade it. It would have been nice if he let me pick it out or add money to it to get the right laptop. The CPU is a Intel N2840 which I read is not very fast and may not play Netflix movies very well. The ram is only 4 GB. I don't even know if I can upgrade the memory in this model or not. Please help! I have a Toshiba Satellite S855-S5252 that I upgraded to 16 GB of RAM. It has a Intel I 5 Core 2.50 GHz . I have loved it but the screen cracked and it has some age on it and when I mentioned to my friend that it was time for another laptop, he jumped the gun and bought me the cheap one. I don't mean to sound ungrateful. I just wonder can I do anything to upgrade this new computer that is coming in the mail.
