Start the laptop and then shine a flashlight at an angle close to the laptop screen and check if you can see any images at all, either try in BIOS or when the laptop is booting into Windows.
They will be very faint if they are there so trying this in a darkened room may help.
If you can detect any images then there is a backlight problem with the laptop display
If you can't detect images is the laptop fan turning on and are there any signs of activity with the status LEDs on the keyboard.
If not then the laptop may not be starting or passing POST
Did you disconnect the battery when the laptop was turned on? If so was the charger also connected at that time?
