    Hi,

    I have recently bought new T43 and very satisfied with its performace and etc.

    But there one strange think which does not let me sleep well.
    When my T43 is working on a battery and I plug USB mouse (actually whatever I plug into USB port) I can hear strange very high noise.
    It happens that the noise stops until I move my mouse again. When the mouse is still then everything seems to be normal.

    It also happens that this strange kind of noise (very high - like something electric) occurs when T43 works on battery and performs some activity (clicking the link on the web, startup of application). Just like that sound was hearable only during cpu "activation" periods.

    Everything gets to normal when T43 works on AC.

    Any ideas what may be wrong with my T43?

    Thanks for any help.

    Regards,
    Sebastian

    I can hear a faint noise from mine when I transfer data at high speed over ethernet. not sure if it is the hard drive or what.
