I have a Dell Latitude D820 and would like to upgrade my current T2600 (2.17 GHz) processor to the Intel Core 2 Duo T9400 2.5 GHz processor.  What I am having trouble finding out is if this new CPU will fit and work in my current laptop.

Where can I find a guide to compatible CPU's for my Dell D820?

 

Thanks for any help!  :emotion-21:
