Laptop RAM upgrade. Need help.

Hello everyone! I'm currently using Acer Aspire 4750G.

My RAM is standart which is 2GB. It's not enough for me, since last time i mention that my laptop started lagging sometimes. Especially when i use too many webpages instantly, or running to many programmes.

Is it possible to upgrade till 8GB?

What is maximum RAM memory is supported by my laptop?

I heard from my friends that they upgraded their RAM till 16GB, but laptop didn't support so much memory, therefore it using only 8 from 16GB. Will i face some problems like that if i put 16GB or 8GB?

And what is the best RAM for ACER? Kingston, toshiba, or?

P.S. Sorry if i posted wrong or made mistakes, first time posting!

Max ram for your computer is 4GB or 8GB. if you have now 2GB try to buy 4GB ram and install it and see how it works then install another 2GB take it from another computer for testing issue and see if it works buy another 4GB and install it. This way you will have the max amount in you pc.
