Beeping computer that affects brightness intermittently

Please help me stop the intermittent beeping that also affects the brightness on display.  Thanks.

Sounds like a power issue, something changes with your power causing the beep and the monitor goes to low power mode.

Laptop or Desktop?

What happens before the beep?

Thank you...changes were made in my location from one house to another - from one internet connection to another.  But the beeping began at my home and continued through usage there and then when I set up at the other house again.  But...the beeping stopped shortly after I had sent you the problem...no kidding - is that magic?   LOLOLOL  thanks for your reply - and the info....this is a laptop.

If the problem returns I'd suggest pulling the battery and AC adapter power and then reconnecting.  Sounds like something isn't connected firmly.

Thanks for the advice to pull the battery - how do I do that?

You'll have to look at your manual as this varies by machine.  It may not be possible, depending on the machine.

Thanks again...I will get on it tomorrow.
