The laptop is officially dead unless you can obtain a correctly programmed BIOS chip from the manufacturer. It's possible that the BIOS chip is not replaceable and you will need to buy a new motherboard. I suggest you inquire into factory servicing to resolve the problem.
It was not the first time I was updating the bios manually. It sometimes freezed and I wont turn it on and it will work. So, are you really sure I will need to change the motherboard
I went to a computer technician and he said I shouldn't have disconnected the charge while updating the bios]. Thus, it caused my power charge sector to overload
