Upgrade from Core i3 2nd Generation to Core i5 3rd Generation?

[HassanSyed]

Is it possible to upgrade my HP ProBook 4530S from Coire i3 2nd generation to Core i5 3rd Generation by the replacement of CPU?

Unfortunately, your (Intel 2nd Gen.) sandy bridge processor will work in an  (Intel 3rd Gen.) Ivy Bridge chipset system board, but not the other way around. 

The answer to your upgrade question is a no.

The Sand Bridge\Ivy Bridge chipset\processor was always a tricky issue.

What if I replace my Core i3 2nd generation CPU with Core i7 2nd generation CPU?

The 2nd Gen Intel Core i7 processors on the specifications document on the link below are compatible.  I suggest finding a known working second-hand unit. The new ones are still quite pricey.  eBay may be a good source for this.
