    The bios does not start.
    The pc no beep. The fans and the hd do not start.
    By pressing the on / off button the pc does not turn off.

    The BIOS start, but the PC does not turn on.
    The WiFi and Mute buttons are on, the LEDs Cap Look and Num Block blink. The screen does not turn on.
    Do you have the electrical schematic of my motherboard?

    I have no backup bios file, can I still remove the bios password?
    My preference is not to use bios chip with eeprom reader (the hassle of using solder, etc)

    If not, how to make a backup from the current bios (the windows is corrupted too, thus unable to login to Windows to run a software to do a bios backup).

    Thanks
