Saltgrass, i appreciate your response. i am getting a single Beep, Beep, Beep, Beep an so on lasting for about 15 or 20 seconds. The A and S key do not respond though the remainder of the keys operate. The touchpad is not operating either. Sometimes it does, sometimes it doesn't. I have the unit booted as i am sending this response...feel really frustrated. I have the feeling that the MB is ready to bite the dust. When i press the Fn+F7 key i now can operate the touchpad...OMG...if I could determine the reason for the Beep and fix that I would be able to cope with the other problems. The website is simply useless.
