x14 R1, no post, 2 red 7 blue lights

Yesterday I was using the laptop as usually (it is 2 years old), I left home and when I arrived to use it again the laptop did not “turn on”. In fact, it does turn on the keyboard lights as well as the fans but no display is shown, not even the typical Alienware text prior boot of the main OS. More over, in the keyboard the turn on key shows everytime 2 red lights following 7 blue lights. In the manual it says it’s a POST problem with the BIOS however I do not find any solution at all.
