Sorry, here is the corret file. i dont know what to change

[brzostos]

Try this BIOS, should work with it...

Try this BIOS, should work with it...

[brzostos]

I'm bumping the topic, would someone help me unpack a clean BIOS from the manufacturer's website?

[brzostos]

The laptop does not respond to the power button, voltages of 3.3v and 5v are present. On the 3.3v switch it drops to 0 when pressed, charging the batteries.
