Hi, my laptop's screen turns black after I wrongly downgrade my bios. It went blank during the update. So, I hold the power button to shutdown then turn on again. The next thing I knew is the black screen. I've already tried to unplug the battery and ac and press the power button for 60secs, even tried replacing the CMOS battery but none of those work, and the bootable USB with my bios on that too, but it not working.

    Yes, you must ship the notebook before technical support can retrieve the bios. The crisis recovery process cannot be published here in the community as there is a high risk of permanently blocking the notebook. If the bootblock area is intact, acer technicians can use recovery crisis without having to rewrite the bios on the chip.

  • The downgrade process is much riskier than updating uefi-bios. Only Acer technical support can use recovery crisis to restore the bios.
