No. The computer would still boot, and you may also hear the fan running. If the screen flickers, is blank, or dim, then you may be suffering from a bad inverter board.

Whats wrong with a laptop when the screen is blank but the computer is on?

Take a closer look at the LCD screen. Can you see a very dim image on the screen? If you can, most likely there is a problem with the inverter board. The inverter board is a power supply for the LCD screen and when it goes bad the screen looses backlight. The inverter board is located inside the laptop display. In order to replace it you'll have to open up the display panel.
