Mrfox is awesome helped me out a few times when I needed a m4000m modded :) ATM I'm looking at unlocking my bios . Since I have the ranger and I have a very odd screen the is edp but 60 hz yet Optimus works .??? Very odd plus opening up my laptop both display cables lvds and edp are plugged into the screen . Idk how bit they are . I got my ranger used the guy bought a screen replacement I've tried u plugging either cable thinking maybe he made an error but with either cable unplugged results in the 8 beeps or so . So it's a weird configuration but it works and the screen looks great . Anyway point I'd I'll keep an eye out for an rtx . I did find a rtx 5000 for 600 hp but I'll then need a bios chip and programmer . Long story short of anyone can provide a tutorial on flashing the a17 unlocked bios od appreciate it
