thank you soooo~~ much ^^

I'm just wondering, can I put the U5420 chip in U5410 position?


Sure you can but what are you going to put to U5420? Get a couple of new ones and be done with it....;-)


oh~I've got a spare logic board... there is U5420 on it but not U5410.

I'm not an expert... I'm just trying to figure out how to fix my mac. It took me a month to find out the faulty part and to prepare necessary tools. I still got a long way to go to fix my mac.

Anyway thank you so much for your time and help ^^
