I have an HP dv 1040 laptop and I just recently got a NEW mother board put in it because I plugged it it to an outlet and heard a "pop" I would not turn on at all.

I got it BACK a while ago and about 2 hours of use and no problems it started making some buzzing noises. It sounds like I am getting some feedback from the hard drive but I am not sure. I took it apart to see if any speaker wires or hard drive was grounded out or wires exposed I didn't see anything that looked out of the ordinary.

Does any one know why this might happen?

When I turn it off and then let it sit for a while the sound doesn't happen right away when turned on but as soon as my COMPUTER is loaded and I open a program the humming / buzzing sound begins.

Austinsounds like electrical noise from the HD. this is the phenomen like when you feel static on the TV while the vaccum is running. i suggest in replacing the speakers, adding a filtering curcuit to the speakers would probably void the warrnty and is hard without some soldering/electronics experience.

Sounds such as this OFTEN occurs when you are using your phone near the computer. Static noises is the term they used to describe such sound.I would return it to the SHOP that replaced the MBoard immediately...something isn't right.
Laptops are not designed to be self-serviced.I tried calling the place back to get it fixed but there is no answer and it was in Florida. I am located in Ohio. Everything works fine but the sound is unbearable. help.Do they have a website ? ?
