I know, I know. I'm being extremey finicky and it's effectively a non-issue.
I've done some research and it seems like many keen eared users have also noticed this on other MacBook models.
Whenever the backlight is turned on, if you put your ear to the keyboard around the '8' key there is an tiny tiny electrical buzz (almost like a dimmer switch - which doesnt surprise). By tiny, I mean the room has to be near silent to even notice this, however, I often use the machine in bed in my flat and ever since notcing it it's driven me crazy worrying it's a defect.
So my questions are:
- Is this normal and functioning correctly (there are no symptoms)
- Does your MacBook (preferably Retina) have this extremely faint buzz.
As said, Im being extremely anal, but having paid £2500 I want this thing to be out of box perfect.
Hey guys. I recently just bought my rMBP (2.6 ghz &16GB of RAM) and immediately noticed this issue as well. Needless to say, it IS not that big of an issue but some of us are OCD and admit to wanting this thing perfect for what we all paid for it. I'm one of those people. I first took it to Apple and they said they could not hear the buzzing noise even when they took it to the back....ok apple. So I called Apple technical support again and i asked them to refer me to another authorized Apple retailer and service center. I went there today and again the apple technician said he could not replicate the noise I was referring to. But he ended up telling me that Apple claims the noise we are hearing is actually an extra fan that prevents the keyboard from overheating due to the backlight of the keyboard?....I'm not buying that assumption. But as far as Apple tells me, they simply don't see a need to replace it.
I've got the issue with the keyboard backlight on my MacBook Pro Retina 2,3GHz in the Apple Store in Munich repaired (see my post on 10/26 in this thread).
It seems that the buzzing noise was caused by a voltage converter, which is shored in the top case in the upper right corner. The noise was similar to the dimmer unit of a dimmed low priced floor lamp.
