Talk:Problem with Pixel Error

During the first day of work, it didn't strike me (even though I tried hard to check for pixel errors, but maybe I didn't have the right lighting) - but today on my 2nd day of use, I detected a blue pixel.

Questions

• Is this a reason to return the device or does it happen anyway sooner or later?
• Can there anything be done about it?
• What might have caused the pixel error? I believe there is a irregular spot surrounding the very pixel (like a puddle of water 1 cm in diameter) - but I certainly didn't put anything between screen and keyboard when closing.
