I am trying to fix the code 12 errror but so far i had no succes. The laptop i am using is an old acer extensa 5230e model. T7700 intel dual core and 4 GB ram. I must say, for an old laptop with an SSD drive, the thing is actually not so bad at all. It's just the integrated graphics are very poor. So what i did was a bought an external adapter. I tested 3 different cards. All 3 where detected, latest drivers,... alway's code 12. I known for sure that it can be done. (Everything made by humans can be fixed by humans) I am for sure the cards are working fine, and ofcourse an extra monitor and psu. That's not the problem. Now i've tried to override the DSDT (tread i found on this site) but unfortunately i am stuck in my cmd. I put a link below with a screenshot. It say's missing input filename. What did i do wrong? Yes, i am still learning about DSDT but i think it's very interesting. Mayby someone can help me to better understand it. Chris Zippyshare.com - a.jpg
