There was nothing wrong with my laptop before this incident it was working perfectly fine 10 minutes ago but when I opened it again, the screen was black. I followed the procedure by taking out the battery connector and draining all the electricity. But there was still no fix to it, then I did the fn diagnostic and I couldn't see anything. Although I can see the screen very dimly if I shine a flash at the screen. What should I do now?
Thanks for posting. Apologies that your system is not performing as expected.
Have you tried using an external monitor? This would check to see if the GPU has failed or if the LCD has failed. If you are able to get an image on the external monitor, please run the diagnostics again, make a note of any error messages encountered, and post back.

If you still require assistance and the system is under warranty, you may contact me privately. Be sure to include your personal information (name, address, telephone, email) and your computer's service tag number in your message. Thanks.
If there is no warranty, then you could contact our Out of Warranty team to get a quote for a paid service request.
Were you able to try any of the above suggestions?
