[Dudu2002]

hello, I have a little problem:
I received my laptop bios modified (lenovo b50-70), I flashed the laptop and everything was ok until I changed a parameter at the video card IGD to PEG. Now the screen is dead and the laptop does not get to POST. I managed with the combination FN + R to access bios recovery, I found the name and file extension needed. l started the procedure and it reads usb stick then i receive 3 beeps and laptop restarts. can someone help me please

Hello!

I also have a B50-70. I don't know how I did it, but I managed to get the "Advanced" tab without modifying anything. Just pressed some buttons. Although I have no idea how to repeat it. Anyway, I'd like to make some "Advanced" adjustments too...

I did the report as you asked https://www.sendspace.com/file/smckwt 

Thanks and looking forward to hear from you!

Hello!

I've been using this BIOS for about 10 days and everything seemed OK until now.

Now it's just black screen after I press power button. I tried removing HDD, RAM etc.

How can I revert to the stock BIOS?

Thanks!
