Laptop keeps making usb noise?

Hi there,
My laptop keeps making the usb noise randomly, like when you plug something into the usb port. It's getting terribly annoying and I wonder if there is anything that I can do to fix it or atleast stop the noise.

The only thing I use in my usb ports is my Maxtor hard drive thing, but I haven't had that plugged in for awhile. So at the moment only the charger is plugged in, however it keeps making this noise.

Another problem is when using the laptop for quite a while the mouse pad will suddenly not be responsive, it's also really fustrating.

I don't have anything big installed on this computer, no big games or programs. And I've only had it a couple of months.

I hope this makes sense and if there's anything else you need to know please tell me!

If you've only had the computer for a couple of months then you really ought to contact Dell about the problem. It sounds like a hardware defect of some kind.

If your sound is enabled and the volume is turned up enough, in 2000 and XP at least (I haven't used Vista yet), you normally hear one two tone pattern when a USB device is first plugged in, the opposite two tone pattern when you unplug it, like the two tones for a front doorbell on a dwelling (ding/dong, dong/ding).
If a USB plug or a USB port is physically bent or damaged, you might hear those two tone patterns randomly. You might also hear that if a USB extension cable has something bent or loose somewhere between the device and the port. Take a look at the USB connector on the end or the cord of the devices you have plugged in, and the ports you plug them into, for bent metal, or a missing or displaced plastic blocking plug. OR - if you have EVER unplugged a USB cord by pulling on the cord rather than the connector on the end of it, which is VERY common for people to do, you may have broken wires inside the cord - if the wire's insulation is intact and the broken wire's ends are still touching each other, the device still works, but the connection will be intermitant rather than rock solid reliable - you MAY hear the sound for unplug/plug in when you wiggle the cable near the USB connector - if in doubt, try another USB cable.
