What is "not MB is better to have 667MHz or more",
Battery will cause to slow down laptop 1 de ah?
If I not a graphic student, do I wanna refer that too?

Usually the RAM MB is the size of a RAM but the speed transfer between RAM n MOtherboard is depend on FSB...
Front Side Bus...so is better to have 667MHZ or higher FSB speed...mostly it won show on spec but u have to check on the Notebook Manual/ Spec page...

Ya...low or slow battery voltage provide to laptop can cause the laptop have not enough voltage to operate smoothly n slow down the laptop performance...mostly low battery voltage provide is only b active wen the laptop battery is nearly empty...

u should refer to Cache Memory also know as L2 memory in spec...
RAM FSB speed

i think tat should b enough...is better to have bluetooth n webcam included...
