Beeping sound comming from Computer?

[Slugs]

There is a beeping noise in the room with my computers. It is a beeping noise. I removed all electionic devices from the room.

No effect. I unplugged everything in the room, no effect. I killed the electricity from the utility and no effect. It has to be something run by a battery giving an alarm. However, I removed both desktops to another room and it is still beeping. I

disconnected the smoke alarm no effect, I took out the battery, no effect. I am thinking there is a battery in my computer does it give an alarm when it is about to go out????? However I removed it to another room and that didn't have any effect.

I am at a loss to know what is beeping. I went up in the atick and can't hear it. Just in the computer room even when I take

the computers out of the room.  Anyone got any ideas????????????  HELP  Syd Horn
