Hello Cipriaan,
Thanks for reply.

I tried to update BIOS and it failed then Pc became freeze and I cut off the electricity and put out battery,
I hope you can find a solution

I see. You will have to take the PC to an specialist at a computer repair shop. He could give you closure to your problem.  He will take the BIOS chip out of the laptop and write a new BIOS on the chip and then solder it to the motherboard.

I did the same you mentioned in one pc repair shop in Düsseldorf (Germany) he said there is no problem with BIOS chip.
I think it's the problem occurred Bios software and I can't find bios-boot-usb-stick

The problem is software related of course. But to fix that you have to write a new BIOS on that chip. The only way i know how to do that is to unsolder it from the motherboard put that little chip in a BIOS-write interface and solder it back on the motheboard. Of course you can try flashing the BIOS on a USB stick but i don`t think you can do that if the screen remains blank.
