macbook proscreen

I have a Macbook Pro (2015). When I switch on, I can hear the fan noice but screen remains black, no backlight (No light on the Apple logo in back). I checked brightness, restarted mac several times, reset the System Management Controller, followed these steps but no luck. Any ideas?

EDIT: Battery is dead

Best Answer

You could try resetting NVRAM and PRAM. They store system settings that might be related to the problem.

Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P and R. You can release the keys after about 20 seconds, during which your Mac might appear to restart.
