My Dell Inspiron 15 7000 series recently began to have this weird irregular static noise coming from the keyboard. I doesn't sound like it's coming from the speakers. It's only faintly audible but still annoying. I'm also wondering if I should be worried about it. If anyone could help that'd be awesome, thanks.

Possible that laptop FAN is causing this problem, please follow the advice below:

1.Power off your laptop, now using your phone's flash light or other decent torch check the air vents of the laptop fan, we check for dust, thus may either easily noticeable or not, but if not does not necessarily mean its not a dust issue and vice versa. Therefore you may need to remove the back panel of the laptop.

2. Only attempt taking apart the laptop if you know what you are doing and completely free static, check youtube for help before attempting completely to get abreast of the situation.

3. Once your laptop panel is removed, check your fan, gently nudge with your finger and see if it spins freely, if it does not dont panic, now gently gain using a air-can remove the dust. Now remove the fan from laptop, and use if possible a static free soft brush and remove what remaining dust. I had done a similar repair on an HP laptop not so long ago, where fan refused to move, i did the same steps i just outlined and then proceeded to take apart the from its housing and continue cleaning. The fan now moved freely and i installed it and powered on the HP and the laptop worked like normal.

5. One should note not all laptops will emit and high pitched noise when the fan is faulty, some will switch off.
