Display problem

Hello,
beep just not display on screen without battry power direct on system but system is not working

brevity in this case is not a virtue.

Are you saying that the computer gives a POST beep? Or is it giving a beep code (more than one beep).

Is this a laptop? A desktop? Did you make any recent changes to your system? Does the screen turn on at all? Can you hook up another screen to see if that works on the system?

What is this battery power? Is that for the laptop? Is that a UPS? Or something else?
