    Hi friend,
    using an HW SPI External USB Programmer You cen rewrite your Bios Mod into laptop Eeprom !
    I don't think Acer Service will do, but a private reparateur can do !
    It needs to desoldering Chip from MoBo : GigaDevice GD25Q64 8192 KB (8 MB) read all contents (make a Full Dump) !!!
    Then We have to modify Bios Region to apply the Mod and then rewrite back into Eeprom, so soldering again on MoBo.
    You can try using a Soic Pomona Clip too, many times It works, so without desoldering Eeprom.
    Let me know
    Regards
