MacBook won’t turn on
My Macbook 2011 i7, wont turn on when pressing the power button. There is no chime, fan or any indication its alive. Theres greenlight in the magsafe when plugged to machine but no orange. I’ve tried the ff, reset SMC, holding the power button for 10sec, unplugged the battery and pressed and hold the power button for 10sec, and press again, but no luck.
Ive tried to power it up also thru power pads direct in the logic board, but it ddnt light up. Im was thinking to replace the DC board but I want to learn first what is alternative to do. How would I know if the failure is on its battery, keyboard, ram or worse is on its logic board?
Btw, just a segway, I was having GPU failure before this problem, I was lucky to repaired it by reflawing and re-applying the thermal paste. I was able to power it up and loaded the screen successfully. But on the 2nd or 3rd try, it suddenly ddnt load up, and completely dead.
