    I didnt really know where to ask this question,

    But due to my low skills in electronics I want to know this.

    The shiny logo at the back of apple laptops, and the shiny sleep indicator, are these some kind of lamp? If so, dont they ever run out of electrons? Like when you have to change your light bulbs at home. I have never heard of them stop working so I guess they work in some other way?

    Thanks

    The Apple logo is lit via the backlight of the display, thus if the display dies, or is just switched off, the logo is not lit too.

    The sleep indicator light is an LED lamp, thus it will die long after you have replaced that Mac.

    from http://www.apple.com/macbookpro/design.html

    and http://www.thebookyard.com/product.php?manufacturers_id=30&products_id=5795

    both found via http://www.google.co.uk/search?q=macbook unibody sleep light&ie=utf-8&oe=utf-8 and http://www.google.co.uk/images?q=ma...&source=og&sa=N&hl=en&tab=wi&biw=1388&bih=844

    LEDs last decades. The Apple light is using the screen's backlighting.

    LEDs have a very long life span. You don't need to worry about them burning out.

    Btw: the Apple logo isn't a separate LED - it's the screen backlight shining through a cutout behind the display.

    I have a PC that's older than me, and the leds still work:D and the pc too:p (the pc has at least 20+ years).

    Your hard drive most likely to be the first victim of age, but I still have an 100MB hdd that still works, so sometimes it's more luck than anything else.

    Enjoy your macbook and don't worry about it, just take good care and don't drop it:p
