Hi,
I know that some laptops can have their cpu upgraded.
I have a intel Celeron CPU in my toshiba sattelite l300 pslb1a and I was wondering if I Could upgrade it to a dual core?

Heres some specs. (my only worry is that the dual core cpus don't go on my socket motherboard)

Code:

Most instances this is not an option...i'd check the manuf. site and or have a shop look at it.
But most likely the answer is no.
