Vostro V13 Upgrade

Hey guys,

I am looking for a little advise. I love my Vostro V13 laptop as it is nice and slim, light weight and pretty good for the money.

After many years of good use, I am looking to upgrade it.

I want to know if anyone can give me the specs for the motherboard so I know what kind of CPU I can upgrade to, or if another type of motherboard would work in it that can cope with 1) the physical space 2) the slimness of the laptop.

Any help would be most appreciated.
