Hi friends.
I'm Fabio from Brazil, and I have some experience in repairs of Mac
Today I have a Macbook White 2010, which does not recognize the Ram. Already tested everything, and the problem is the logic board. Comparing with another good card in some places where there should be 12v appears 3v or less. Advanced User already had some similar problem, who can help?

Try sticking only one good RAM stick in each RAM slot and try to reboot it. If that doesn't work, try booting it without any RAM in it and it should let out a long beep. If it lets out a long beep without the RAM, then your logic board is still good. If not, your logic board will need to be replaced.
这个答案有帮助吗？
Thank you friend.
I already did these tests, I really have a bad logic board, but the cost of it here in Brazil is high. So I'm trying to repair it.
My hope was that someone had the same problem and know where the fault in this logic board.
I know this is not useful, but I have a 2010 MacBook board with the exact same problem. I'm not sure what's causing it. My board suffered liquid damage though, so it's hard to say what caused it. I'd love to find out what components are responsible for the problem though.
