Acer boot-up speaker noise?
I have a laptop that when I first press the power button the speakers start to make a horrible crackle noise when in the BIOS. When the Microsoft OS screen comes on the speaker noise usually stops. Then everything is fine. What could be making these weird noises at boot-up? The brand is an Acer Aspire (somewhere in the 5100-5200 family). (With camera and microphone.) The OS to which it normally boots is microsoft but I have some knoppix cd's. I doubt that it could possibly be the OS though because the noise only occurs during the first few stages of BIOS startup. The speakers then work fine :-/ what could it be ?

Well the only thing that I think that can cause the problem is a loose connection (but you said that it stops, so that is ruled out). Or maybe you are getting insufficient power when your laptop turning on and powering all of you accessories. You can try checking the drivers under device manager (by right-clicking on my computer>properties>hardware tab>device manager) and look for conflicting drivers; but that sounds like that is not the issue either. Hope this helps. Good Luck!
Replace the damaged key board and any other damaged components. Take to a computer repair center and have checked out and a estimate for needed repairs.
