    Noise when touching laptop keyboard or bezel


    Shuffling paper, scratching bezel or touching keys on laptop keyboard creates magnified noise some of which is very high pitch, heard through the speakers, but inserting ear piece jack kills the sound which is not heard through the ear piece or when the earpiece jack is inserted. Unplugging laptop has no effect.



    Windows 7 Ultimate 64-bit on Clevo P151HM laptop

    4 NVIDA high definition audio and 1 Realtek high definition audio

    8 2.3 GHz processors


    Thank you.

    Hiyya gwatts mate first some system specs would be good System Info - See Your System Specs I know you have posted some but this is a better way to see what you have got. Speccy is another link too.
    Speccy - Download

    Now for that problem I have not many suggestions except download the driver for the audio again
    The Sager NP 8130/8150 (Clevo P151HM1/P150HM) Owner-Answered Frequently Asked Questions **READ BEFORE POSTING** is the best I can find

    sounds like a grounding issue if it does it when your just touching it. does it happen if you put say a non conductive thing on it? My old tablet had that and when you held the bezel with only one hand the digitizer would not calibrate properly, same concept.

    I appreciate your replies. In the meantime I had reinstalled an old image which cured the problem. If it recurs I will try the superb suggestions and repost.
