    As i sit here any type, i can hear my 85w powerbrick making a faint squeaking sound. It is especially audible when you put in near your ear.

    My uMBP is mid 09 and is not charging as this occurs.

    Is this normal? i don't want my house to burn down as i sleep :p

    The powerbrick is supposed to hum due to the internal components moving as electrical current passes through them, the squeaking noise that you are hearing may be just that. However I can not be 100% certain without hearing it.
