When I turn on my Dell Windows 7 laptop the screen is just black

All my lights on the key board are working, the sound is working, but the screen is just black

Do you still see the splash screen when you turn on your laptop or is it just black when you turn it on? Here are troubleshooting steps that may help.
- Start with a hard reboot, remove the battery and unplug it's AC adapter then press and hold the power button for 20 seconds then try booting it.
- Next is to try to boot your laptop without its battery and just use its AC adapter.
- If it doesn't work reseat the RAM, remove them all for couple of second then put them back in making sure everything is seated properly.
- Again if these doesn't work but you can hear the laptop on but with no display, connect an external monitor and see if it would display anything because if it does that means it's the built in display that is faulty.
- Next to try is if your AC adapter is still okay by trying another AC adapter that has the same voltage and see if it would work.
- If all these will not work it would be a motherboard problem.
