if my charger is putting 17.8 volts is that enough to pwr it on? i have 15 inch mid 2012 mbp. it was working fine I shut it down and later was unable to power it on since. It was able to charge the battery to full.
I do not read any voltage from the U6900 VCC pin 5, and I checked and saw that I do not read anything form SMC_BC_ACOK. The 2k resistor is fine. I replaced U7000. I read 4V at CHGR_ACIN but the new U7000 chip is not outputing anything for SMC_BC_ACOK. Is there a chance that the SMC is causing trouble for U7000 and causing it to burn out?
good luck,i have mac pro early 2009 no power,Sometimes it works then stops! I doubt smc ic but i have not 820-2337 schematic and nor datasheet smc ic How to check smc ic?What is the solution in your opinion?thank you.
Nice. Straight to the point which is what a video like this should be.
أحسنت، هذه دقة في التشخيص، أحسنت.
absolutely brilliant, thank you.
You are best sir
Parfait merci ☺️

Did you find the problem?

No power could be many things. The questions is very general. You need schematic and board view to properly diagnose a board.
hello;yes exactly but where can i find schematic for 820-2337-a?thanks.
Hi i come from thailand can you help repair macbook pro 2011 /no power no green light (i not have pattern )
I thought Tonny Ja and Tongo po can do everything
