Hi, need help with a Macbook Pro 13", 2012, motherboard 820-3115.
Board boots and don't detect RAM, have try different known good RAM and nothing.
Board don't have liquid damage, the problem just appears one day, not gradually, no freeze screen or ramdom rebooting before.
PP1V5_S3_DDR is 1.5 volt
PP075_S3_Mem also normal
PP0V75_S0_DDRVTT also normal
Anything I need to test before thinking is a CPU problem?
