Hi,

Want to upgrade CPU and need to make sure of the Socket Type?  The .PDF manual I have just have for my laptop just have:

Inspiron 5447: 
4th generation Intel Core i3 ULV
4th generation Intel Core i5 ULV
4th generation Intel Core i7 ULV

Inspiron 5448:
5th generation Intel Core i3 ULV
5th generation Intel Core i5 ULV
5th generation Intel Core i7 ULV

But does not include Socket Type.
