On the upper right side of my keyboard it reads, "compaq", and underneath that is, "1", "A", and a down arrow. The "A" light has been coming on when I start my computer and seems to interfere with starting up. There is a beeping sound and only when I reset, (or push on button again), does the green light switch to "1", and all is well. I bought the computer/moniter, etc., used and have no instructions. Obviously, I'm computer stupid, but please tell me what's up and what the heck those, "green lights and A, 1, etal mean. Sorry to post what I'm sure is a stupid question.
