[M17x R4] - 'unlocked' BIOS versions in Alienware M17x / AW 17 Posted May 2, 2019 Well... I met another problem with my M17x R4. I used last BIOS Mod version from svl7 and configured in video settings more vRAM for iGPU (increase to 1024 MB from default 256 MB). And now laptop can't start - it cannot even reach BIOS loading, just enables backlight and shuts down. Of course I removed CMOS battery, I even tried to forse reset BIOS with End + Poweron, but it doesn't help. I am afraid in two ways: I've broken south bridge or I've broken RAM. Any ideas?
