[glow=red]No is not ilegal[/glow] to increase a ram from a computer , you only need to know how to.
(remember even if you increase a ram from a computer doesn't mean will be more fast.)- to be more fast you need to know whats the hardware is slowing down your pc.
can be: hhd(hard disk), ram(velocity/performance) and cpu (velocity/performance), also gpu(video card) for games.
before put/remove ram be sure off:
-is the same ram type.
-you have slots to insert another ram-.
-you have every tool needed.
-(dont update ram more then 4gb for 32 bit systems, not worth.)
if you playing in a[glow=red] desktop[/glow], turn off and remove from electricity and press power button just to remove static energy. then open the desktop with a tool . then in the ram slot you need to insert the ram . by pressing in a jumper near the slot.
press down and the old ram will go sightly up.
at insert put the ram in same position , that you remove the old one and just put it to the jumper goes up again . you will hear a noise. is the ram already corrected inserted.(in case of the other slot just do the insert process.)
- in a[glow=red] laptop[/glow] depends a lot. normally behind lower case laptop, you have a cover that you have to remove . and is like the desktop, but with a metal jumpers in the sides. and you need to put it in the diagonal.
- some laptops are not upgradable, other are to hard to do and you need to send it to brand to do that.
[glow=red]Other thing -> if the computer have a seal of the brand and is new make sure you go to the brand that your computer is to increase it.[/glow]
