What does a screen 'chip' actually look like?

    Hi, just bought a secondhand Macbook Pro from eBay and just have a question about the screen.

    There is a very small 'dot' on the screen (about the size of an old-school CRT pixel) which appears white when the screen is off and black when the screen is white. It is also slightly raised so I can feel it very faintly when I run my finger tip across it.

    The screen was filthy when it arrived and there were similar marks on the screen but these seem to have come off with screen cleaner and a microfibre cloth however this one remains.

    Is this a chip? I had assumed a chip would be concave but this is definitely raised...

    Any ideas?

    No, your screen can't chip. It is not made of a hard material.

    Hmm... wonder what it can be then. Certainly doesn't come off with the maximum amount of pressure I'm confident about using to try and get it off...

    MacBook Pros have had a glass cover over the screen since the unibody models were introduced in 2008(unless we're talking about the anti glare option, I'm not sure about those). That glass cover certainly can chip. Although it wouldn't leave a bump.

    The glass should be totally flat after the manufacturing process. If it wasn't it probably wouldn't have left the factory. And if the original user found that, they probably would have returned it.

    It could be a piece of debris (food? lol) stuck on the glass. Try resting the Mac so the screen is flat, moisten or put a drop of water on the bump for a bit to see if that can loosen it.

    I've bought a few used Mac and sometimes it has taken a few cleanings before it is totally clean.

    It's called an an exploding or bright pixel they can happen on any IPS screen. Nothing you can do about it short of replacing the screen.
