Hi there,  I have Toshiba Satellite C55-A 1N1 (PSCGJE) with Core i5 4200M processor. And motherboard model is PT10S. I want to upgrade my laptop processor and i have searched a lot and found out that Core i7 4900MQ can be used in the i5 processor slot and also the core i5 is detachable from the motherboard its not soldered to the motherboard. So can i upgrade it to Core i7 4900MQ ?
