LAPTOP IS MAKING WIERD SOUNDS OUT OF THE SPEAKER

My best bet is that the adapter is overheating. I have seen similar issues when I used to do computer repair. As far as I know there is no easy way to fix this besides using it in a chilled environment. Um... other possible problems with the same recomended course of action are: some how a wire got lose inside, a liquid got spilled on it by somebody or something, or it sustained a jarring fall (not likely).

Try cleaning your terminals at the battery, even if not corroded. In my years as an alarm/radio installer I have come across this problem constantly, especially on GM vehicles.

That sounds like you have the speakers wired to the positives only.

possibly a rear axle bearing. they do make a roaring and whining sound when driving.

possibly yes. this sounds like its overheating and locking up. need to know what operating system you are running and whether you hear the fan running or not

Take the computer to a qualified technician, for professional trouble-shooting (failing bearings in a cooling-fan, or a disk-drive about to die).

Hello,

Something could be jammed, or not rotating freely, maybe an improper alignment with the brushes, or a blocakage within them. Try to re adjust the brushes :)

Have you noticed if the noise changes while doing a swerve to the left or right ? If so , it is likely a wheel bearing & will require replacement of the entire hub .

sounds like you might have a broken fan

that is the water pump, replace it
