Test the laptop on another external monitor, if you get an image there, the fault is probably with the laptop backlight

Can you see any light on your computer? Or hear your computer running? Have you tried turning of the power and turning it back on? Also check if the cables on the back of your monitor are still firmly connected. as well on the computer side.

Monitor is blank when we turn the computer on.


Maybe not. Find the FN key. It is usually BLUE in color
Then look on TOP row of Computer keyb (or all over) and find CRT/LCD.
Press the FN and that key and your screen should come back. You accidentally sw. it to CRT (outside, external monitor)

Self-Test Feature Check (STFC) Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
  1. Turn off both your computer and the monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
  3. Turn on the monitor. The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
  4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

Thanks
