Advice on how to replace p-4 on dell?

I must replace the motherboard on my dell gx270 due to the leaky capacitor problem. Any helpful hints on the best way to remove the cpu. I have read that the cpu comes out with the heatsink. Dell instructions say to keep the cooling fan inplace and pull on a corner and the heatsink will come off. Anyone with experience doing this? Any help will be appreciated. I do have technical skills but I have never dealt with a cpu.Advice on how to replace p-4 on dell?
if the chip comes off with the heatsink that's ok; not ideal but ok,make sure you have heat-sink compound and a wooden swab stick or anything similar; not plastic or metal;carefully grab the base of the chip and turn back and forth very carefully to seperate the cip from the heatsink; just in case the chip is still good; carefully apply a thin even coat of heatsink to your new chip and carefully reassemble:tip(when applying heatsink to new chip make sure chip pins on new chip are protected on the piece of anti-static foam it came with; so as to not bend any pins when applying heatsink. Good Luck! ps: if the chip is subborn yes take a jewelers flat head and at the corner that is keyed carefully put alittle pressure to dislodge chip
