Thank you very much hoaca388 but the screen always remains black I have to look for other solutions, the problem appeared after having modified the secure boot option in the bios so I was convinced that the problem came from the bios.

Notice if any components around the bios chip are damaged.

You should look for other causes, besides the bios.

Re: Black screen Acer predator helios 300

My computer turns on, the fan is on, the LEDs turn on, the keyboard turns on, everything works normally, but there is no image.
Then I looked a little closer and saw that a component was burned. It swelled and exploded, which is probably why there is no picture. Can we know the name of this component?

Here is your new BIOS, it's a virgin BIOS from Acer with no DMI, it should works fine.

Thank you for the help.The bios is ok,the above one too,but the sad thing is that,the CPU died too,if i measure coils they are fine,but if inject Voltage,it takes any amount of courrent,an voltage drops.Mosfets are good,CPU doesnt get V when powered on,anything else has,Nothing to do more,many thanks on Bios help.Regards.
