Hello guys I've got a pretty weird problem with my M18x R2. I already searched the web but couldn't find an answer. A few days ago I changed some settings in the bios, if I remember correctly DMVT Pre-Allocated. After saving this setting the notebook refuses to even POST. I get no beep errors or anything. If I press the power button the system turns on, the leds turn on and then the system shuts itself off. I already reset the cmos, the IME, tested different configurations and so on. If I remove all the memory sticks I actually get the memory error code. At this point I'm pretty sure that the bios got corrupted for some reason when saving these mentioned settings. Did anyone had a similar problem and got a solution for this? I repaired lot's of notebook but never had an error like this... The Bios installed is the a15 unlocked.
