Iv'e been wanting to upgrade this old laptop, Iv'e already replaced the RAM and WIFI card, but Dynabook support just wont give me enough detailed specification on the best supported CPU for this laptop. I found on Dynabook support that you can upgrade it to BIOS version 1.40. I bought this laptop in 2013 so it has a Socket type G2 (FCPGA988). I also need to make sure the CPU I'm planning to get is whitelisted and support by this BIOS version. To my knowledge the best CPU I can upgrade it to an Intel Core i7-3940XM. I want this CPU but I'm pretty sure the BIOS won't support it. Another most likely supported CPU is the Intel Core i7-3630QM. Any advice on how to update the BIOS and whitelist this XM CPU?
