Question lenovo g40-70 black screen when invernate

[reivaj102]

Hi everbody,
I have a lenovo g40-70 core i7.
Historically, when it supend, hibernate or shut down, the laptop keep on with the screen black. To turn on again, I have to force shut down by pressing during 3 seconds the power button.
In order to fix it, some post suggest to install bios update. The current bios is 9acn25.
I found two bios update files:
9acn32ww.exe
9acn30ww.exe
Those files teorically fix the problem, but there were impossible to install because an error message appear:'error: imcompatible firmware'
Is there any alternative to that?

thank you in avance!

Where did you find those files? You want to get them from the Lenovo support site directly.
