I pressed the power button to resume my laptop from sleep, the little blue lights on the machine indicated that it did wake up, but the screen was not displaying.

I pressed the power button again to turn it off.

And then turned it on again, the screen shown the BIOS screen as the following;

DELL
Inspiron 1525 series
BIOS Revision A16

After that, the screen turned black, didn't show anything.

But I can hear the Windows sound (Windows log in sound).

I took the battery out and held the power button for 60 seconds,
then put the battery back in, and turned on the laptop,
the screen was still not working.

I repeated these steps, still got the same issues.

Finally, I shined the flashlight to the screen, I was able to see all the processes since the machine started working, the BIOS screen, Windows logo, log on screen, and finally my desktop, but all these were very dark, without the flashlight I couldn't see these.

My laptop is Dell
Intel® Pentium® Dual CPU T2390 @ 1.86GHz 1.87 GHz
Windows 10

How to fix this problem?

I don't have an external monitor to test this laptop screen.
 
Alas, you are going to need an external monitor to test with, don't have to own one, just see if you can borrow one to test with (instructions on testing below). If you can't, then you need to take it to a tech.

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.
