Bought a refurbished MBP 2.0 ghz machine less than 3 weeks ago. Unfortunately it came with the "whine" and uncomfortably hot! I went over to the Apple Store and left it for repairs. Came back with the following replacements; SVC,MLB,2.0GHZ,256VRAM(M1-CAP)MBP15" CBL,TEMP SNSR,RT FINSTACK,M1 CBL,TEMP SNSR,HEATPIPE,M1 I checked it out for the heat and whine issue and although the whine was less noticable it was STILL happening. Apple releases the article recognizing the issue, I call AppleCare right away. I send the machine back to them and receive it today with the following replacements; PCBA,LIO/AUDIO (m1) MBPRO 15" SVC,PCBA,2.0GHZ,256VRAM (M1-RP) MBP 15" I turn the machine on and...the whine is apparently gone! I had my ear touching the left speaker and all I heard was the processor working, no whine. However, as soon as I plug in the powercord the whine begins. I'll be checking out the heat in a few minutes but if the only issue is the whine when the powercord is on, I might just let it be... ideas, suggestions? What was replaced anyway?
