[strike]It appears so, yes[/strike] http://h10032.www1.hp.com/ctg/Manual/c04642845:

5th generation Intel® Core™ i7 Processor
Intel Core i7-5500U (2.4GHz, SC turbo up to 3.0GHz), 1600MHz/4MB L3, Dual 15W (models with discrete graphics
only)
5th generation Intel Core i5 Processor
Intel Core i5-5200U (2.2GHz, SC turbo up to 2.7GHz), 1600MHz/3MB L3, Dual 15W
5th generation Intel Core i3 Processor
Intel Core i3-5010U (2.0GHz), 1600MHz/3MB L3, Dual 15W

Pretty limited choices since you are stuck with 15W processors.

On further review, these are BGA soldered CPUs on variant motherboards. Since it is a relatively recent laptop not much user based information out there.

Alternate system boards do exist, but given the age of the product, finding one would probably not be that easy.

No, you would need to replace the entire system board.

This is a recent model laptop. I doubt you will be able to find used system boards available. Likely only an authorized repair shop could source them.
