Hi all, after several searches I came across this forum, I hope I can fix a problem with my m17x r4. I have a gtx 680m 2gb gpu and a 60hz panel and i have unlocked bios a15. Everything worked fine and I had the 120Hz panel installed at the time. When I tried to install the quadro p4000 gpu the problems started!! On the first boot I had 8 beeps, then on the second boot the machine booted up but black screen, even pressing f2 to enter the bios black screen, but I know it's in the bios, in fact as soon as I press the power key it shuts down. Desperate, he installs a 60Hz panel and displays the picture. In the bios I see the dedicated graphics card. i exit the bios and load the operating system, and in the device manager i see 2 generic microsoft video cards and the intel 4000. i can't create the .inf file for the p4000 framework, if you could have it for me i would be grateful. So I removed the p4000 and installed the grx 680m 2gb with the drivers from the nvidia site, without modifying it and it installed fine. Now another problem has arisen when I press fn+f7 the pc restarts and switches to the 680m gpu and no image on the display!!!!! Connecting it to the tv via hdmi I have a picture, I can't see the bios by pressing f2, but only when the operating system loads. I tried to reinstall the original bios of the a15 but nothing changes. What could be this problem, the motherboard? Or damaged Bios? Or other? I hope someone can help me reset it. I have been doing tests on tests with negative results for 3 days. Thanks all Now another problem came up when I press fn+f7 the pc restarts and switches to 680m gpu and no image on display!!!!!
