Acer Laptop keyboard problem

I have a similar question. A long while back my down arrow key was completely broken off only leaving a missing whole spot and It can't be used. Now as of recently It seems to be affecting my other arrow keys. A few days ago when I restarted my computer It would stop at the opening load page and just repeatedly sound off like an alarm or a key being held down repeatedly. I have to continue pushing enter or any other key in order for It to stop and continue the startup. Today when I restarted It repeated the same thing above but this time when I logged in anything I clicked automatically scrolled from top to bottom over and over again and there was no way to stop It. No matter what I clicked It would do this. I now have a wireless internet keyboard using a usb port but It is still making the same noises when I restart. How do I disable my acer laptop keyboard?

P.S. I'm sorry for the very long question.

It sounds like you have a problem with your CMOS battery. I had a similar problem with another Notebook recently. The computer does not know its CMOS settings (including the BIOS settings) anymore since the battery is empty or damaged. When you enter the device selection (F12) it saves the information again so it can boot normaly now. I think you should get a new CMOS battery and the problem might be solved. Also the keyboard problem might be fixed with that - i also had keyboard problems with the Laptop i mentioned above when the battery was empty.
