Bengg: Honestly you don't understand laptop at all.
First, each maker decides how to make the 'design' of each model laptop (not even comparing say Dell to Acer at this point) to meet a certain criteria. So a Inspiron laptop is not designed even close to say a XPS laptop (for example) both from Dell, both made in the same year and may both be using 'similiar' hardware. There is numerous instances where trying to 'disassemble' a laptop without the proper service manual to follow the 'RIGHT' steps, causes the breaking of components very easily. This isn't even considering different makers (Dell VS Acer VS Gateway etc.) and thier individual designs.
Second, If you noticed the user in that article just got a 'faster' Duo Core 2 to swap out (really didn't do 'much' realistically) but couldn't swap out from a Duo Core 2 to a i3? to a i5? etc. right? WHY? Because different CPUs sets (generations) are built with specific chip 'sets' on the motherboard to work with them, they are not 'interchangeable' with just any 'better CPU' the user may want. Also there is a limited design on the CPUs as to what ones would work on a Laptop Motherboard as compared to a Desktop Motherboard; in many instances physcially the board itself won't "fit" a 'Desktop CPU' the user may be looking at because they don't understand the differences.
Lastly, The APU design is specifically made for only APUs, a 'low cost, low power' "low end" solution to compete at the same level as a Duo Core 2 to a i3. These are 'entry level' devices meant for Grandma to check her email, not for 'gamers' or performance; i.e. these are cheap because they are for general purpose population. There is no 'upgrade path' as the design is a DEAD END.
The only answer is to buy a proper computer to meet the 'demands' of the user, within the cost price ratio of what the user can afford. Please don't toss random 'techie' links as a solution when you don't understand even the basics (as outlined) of computers.
