If the blacklight stays on for only a few seconds, the backlight timeout setting might need configuring in the BIOS.
NOTE: If there is not a setting for the backlight timing in the BIOS, this behavior might not be supported on the notebook.
Your BIOS version and screens might vary.
Restart the notebook, and then immediately press the F10 repeatedly until the BIOS opens.
When the BIOS opens, use the arrow keys to navigate to the Advanced tab.
Navigate to Built-in Device Options, and then press Enter.
In the Built-in Device Options, select Backlit keyboard timeout.
Press the spacebar to open the keyboard backlight settings, and then select the timeout setting you want.
NOTE: If you select Never, the backlight remains on which could quickly drain the notebook battery power.

Thank you for posting back.
After reading your post, I did go through the screenshot and it shows Dell Backlight.
- Are you using an external keyboard or a built-in keyboard?
- Could please share the picture of the laptop keyboard?
Keep me posted for further assistance.
