Hi Everyone, I'm looking to buy more RAM for my laptop, my exact laptop is this: http://www.dabs.ie/products/lenovo-b5400-intel-core-i5-... I have no idea where to buy some more or what to look for. So if anyone could guide me to the right memory for my laptop, I would appreciate it.Thanks.i Everyone, I'm looking to buy more RAM for my laptop, my exact laptop is this: http://www.dabs.ie/products/lenovo-b5400-intel-core-i5-...
