It will help if you find the schematics file of this mainboard. Then, upload it here.

No, it will not work. Find RP3 and RP4 on the mainboard. Then, tell which one exists there.

RP4 exist ,RP3 nothing

It seems conversion of this mainboard to UMA is either not possible or it takes too much work and troubles. Thus, it would be better if you buy a cheap MXM graphics card or scrap the laptop.
