Processor upgrade

I regret to inform that the Processor that is specified for any Presario notebook model at the time of purchase cannot be changed after purchasing. After purchase of the notebook, the Processor is not an option for upgrade because the notebook computers are equipped with onboard Processor chipset and there is no provision for upgrading the Processor.

This is the reason that you cannot upgrade the Processor in the notebook. I am very sorry to inform this and apologize for this inconvenience.
