You can enter the bios at boot up by pressing the F2 key. From there go to the video section and adjust the brightness setting there to the max to see if that will resolve the issue.
You should be able to do it through the display properties ( in the control panel, or right-click on the desktop and open the display settings from there).
Could you explain more please? Maybe a screenshot or exact buttons/tabs i have to press to get there?
In the display settings i have nothing about LCD brightness, i can launch nvidia control panel but it changes the brighness aka lcolor curve, not the brightness aka amount of light emitted by the LCD. For example. if i'd right now press fn + down repeatedly, the display would be very dull and changing brighness in nvidia control panel would never fix that ever. I need to change the LCD brighness.
Unfortunately, that doesnt help, neither does plugging in another keyboard and pressing up on it and fn on laptop's keyboard. Fn key is not a modifier key like shift or ctrl, its a key that changes the scancode of the key that is pressed with it, so fn+up is sending some unknown scancode (not the codes of up button and fn button)
Maan, it took five months to solve such a simple case! Stupid of me not checking the BIOS though.
However, just a day before i received the solution, i took a Russian approach - that is, plugged the up button out, and stabbed the plastic thingie that is supposed to register key press with manicure scissors, ravaging it until it actually made contact. The button wasnt working anyways, so it wouldnt hurt to lose it completely. Then i was able to return brightness to the normal level.
However, good to know there was a solution for the case when keyboard fails like mine did.

Hissatsu,
Start, control panel, windows mobility center. You can change the brightness from there.
If the computer is under warranty, you can contact Dell Tech Support to get the keyboard replaced.

Hissatsu,
Start, accesories, command prompt. Type
osk
Hit enter. This will bring up the on screen keyboard. You can use the mouse to control the brightness.
