Update BIOS for DELL INSPRION N4030 stuck in the middle

Hi All,

Apparently I made a big mistake and try to update my BIOS using DELL BIOS Update sofware.

The process stopped in the middle and then the comptuer shuts down.

Now when I turn on the computer there is no display on computer and there is a single beep every second.

I tried to press the power button 30 seconds while the computer without the battery and without the power plug but nothing has changed, Any ideas ? :(
