Device is on but has a black screen


Hi was wondering if anyone could help, my laptop turns on but has a black screen ( doesn’t even go on to the logo screen) it beeps 9 times then that’s it, but you can hear the laptop on. I have tried taking the battery out and unplugging the charger etc and still doesn’t work, anyone know what’s wrong?
