unlucky the laptop didn't response anything after loading the bios file from the zip file.The laptop didn't start the booting process, there was no screen lighted after pressing the power button.
btw, the power button was green now it's dark after loading bios.
any help will be appreciated

tried the latest one and still not working.
But saw some changes, the power button became green after pressing, keyboard highlighted at once, but computer didn't go through the start procedures and display was still keeping dark.
any thought for further troubleshooting?

one doubt is that the chip set is not 100% aligned between the real on the mother board(W25Q128FVSQ) and CH341A programmer (W25Q128BV) as there is no such option on the programmer software.
Will it be okay or an issue of such mismatch?
thanks

maybe problem is not bios file
check the chip or other parts too
