My Gateway laptop makes a very loud and unpleasant sound when the AC adaptor is either plugged in or unplugged. The wire (or inlet) happens to be very (increasingly) loose so it will often abruptly come in and out over and over again making a series of loud beeps that can only be ceased by muting all sound on the computer. I once solved this problem a month or two ago by finding a "System Sounds" option on the volume levels and muting that successfully stopped the beeping without forcing me to mute everything else, for a while. I keep my computer on for several days at a time, putting it in "sleep mode" when I'm done using it and just opening it up again when I want to use it again, so each booting of the computer is about a week apart. So after one of the few times I restarted the computer not too long ago, the beeping started again. System Sounds somehow suddenly became completely related to the awful beeping noise, and I am once again forced to mute the whole computer if I don't want my ears assaulted every time I move a muscle with the computer anywhere within a five-inch radius of my body. Is there any other way to get rid of the beeping noise, or any explanation for why the determining factor of whether the beeping happens or not completely shifted from "System Sounds" to some other unknown part of this computer?
