Headless Dell laptop, turn off after flash light

[NelsonMandela]

Hi all
Since Dell produces laptops that last the maximum time out of the warranty and then breaking the hinges or the lcd due to the hinges, I have a few laptops that have stopped working.
The problem is that if I remove the LCD to use them headless, the laptop turns off after lighting the LED 7 times white and 2 times amber.
Is there a way to bypass this problem? I don't have the option for headless in the bios

I was thinking about a modded BIOS or a circuite bridge on the lcd connector.
thanks
