Hello,
My D63 dell laptop always continuously beeps erratically for about 10 seconds at startup. I have been trying to find out why for a long time. I have tried changing its memory cards, but nothing is really working. Anyone have suggestions?
It is possible that you have a key stuck on the keyboard. If you are able to boot into windows, open notepad and see if the keyboard is trying to type anything for you. It could also be a Shift/Ctrl/Alt/Tab key that might not show itself in notepad.
If the problem persists, try removing the keyboard to see booting without the keyboard solves the problem. Here's a video that explains how > http/www.youtube.com/watch?v=mt6M22yPYcc
He shows you how to do it right, just don't do it on carpet like he does!
