Connect an external monitor to it. If still nothing on screen your laptop probably needs a new motherboard, but that's too expensive to make any sense because it would cost almost as much as a new laptop.

Disconnect all peripherals and confirm if system is working fine with AC Adapter only.

Remove AC adapter, Battery and drain flea power. Remove the battery and charger/ac adapter/power cord from your Dell notebook, press and hold the power button for 20 seconds to discharge any residual current inside the laptop. If still not resolved, follow next step.

Check the AC Adapter status in the BIOS. If AC Adapter status shows Unknown / Not Detected, then try changing the Ac Adapter.

If your system is not able to go to BIOS or boot to Safe Mode, then I would suggest running LCD BIST in order to isolate the issue. To run the LCD BIST (Built in Self-test) Press and hold the D key on the keyboard while pressing the power button, then release both at the same time.

This will initiate A grey screen, then Red, then Blue, then Green then White, to allow you to inspect the entire LCD for color purity on each screen and to better identify defect such as cracks in the LCD or stuck pixels that may not be apparent in a normal viewing mode.

Let us know the results

Thanks & Regards

Do you ever get anything on the screen but a backlight - during boot for example?
If not it points to a hardware fault, maybe even the screen itself.

Always pop back and let us know the outcome - thanks

For this kind of issue, please follow up the following steps to check:

1.confirm the battery and ac adapter connect the laptop normally.Maybe the bad connect lead to this problem. If there are no lights when you turn on laptop, one of possible reason is that your adapter is malfunction.

2.the second possible cause is laptop dc jack failure. If the dc jack is broken or loose, you are required to replace it or repair it.

3.Another possible reason is that there is something wrong with laptop motherboard. For this situation, it includs two kinds of possibility,a failure in an electronic circuit and BGA malfunction.
