The most RANDOM MBP question ever!

[Dangerous Theory]

It's not actually a hole, but they use light that is the same frequency as the metal casing so it shines through it.

I assume you mean they use light of comparable wavelength to the aluminium? If that were the case, we wouldn't see it due to the high frequency (we're talking X-ray/Gamma ray).

Why not use a caliper, a magnifying glass, a stand to prevent your hand from shaking, and measure in mm or maybe µm (if you can find a caliper supporting that)?

because no callipers would fit, have you ever even seen a MBP? and you'd need a microscope not a magnifying glass

This thread is so full of engineering and science fail as to be unbelievable.

You can see the holes if you use a magnifying glass when the computer is asleep, and the light is shining through. The holes are arranged in two horizontal rows of about 32 holes, and the whole array is only marginally larger than 4mm wide. That puts the holes at around 50µm in diameter, assuming they are spaced centre-to-centre around 2-2.5 times the hole diameter.

They will have to be laser cut.

Erasmus Probably has the spec pretty close.

If this will help your research, it is the same technology Apple used on the Aluminum MacBook Pros' iSight activity indicator - it illuminates green when active, and is virtually invisible when off.

I agree with the earlier poster - it's these touches and finish that make Apple's designs so attractive. I consider many works of art (I believe many of Apple's designs have actually been displayed as such through the years).

(This tech is also used for indicators on the Apple BT Keyboard, Magic Trackpad, Apple BT Headset, and UB MBP's battery level indicators.)

this is the worst thread I've ever seen on Macrumors.com.

1. Have I seen a MBP? I own 2 like it says in my signature
2. Microscope? Its visible to the eye and can easily be measured in mm with a caliper
Not sure which MBP you are talking about but on the 2 I own (2011 ones) I can easily make out.

 

[Intell]

The holes are less then 1 millimeters in diameter.

Ya, I meant µm like in my first post. My point being, you don't need a microscope. We are talking about the sleep indicator light, correct?
