The system will not POST without a recognized internal display panel.  
I have got an LCD error on my laptop, i know this from the blink code 2/7 however this doesn’t bother me, i haven’t used the screen in years since it’s broken anyways and until now this has never been a problem. I normally use HDMI however this is not working as of today, is there a way I can get the laptop to bypass this and turn on? I would much appreciate it otherwise I no longer can use this laptop..
