Is a 'squeaky' noise from a laptop keyboard thing to worry about?

I have just recently bought a new laptop, and whenever I press the 'l' key; there's a squeaky sound just under the primal. The cardinal is not fractured though; whenever I type 'l' it inputs the character without any issues.

Is this thing to be concerned about?
