    Do you see the Acer splash screen before it goes black? Is there a chance the battery is just too low to launch the OS? Can you plug an external monitor in to see if you get anything on that display?

    Doesn't sound good then. Are you still in warranty? Likely the next step is to get a ticket started if you are...

    How did this start, as a bricked bios that crashes does not happen from normal usage or just like that? Did you do a wrong bios update and bricked this laptop, as the symptoms that you are experiencing are of either a frozen super IO (that controls the Pre-EFI Initialization) or a frozen bios or a crashed bios or a bios battery fault. check the bios battery voltage as it should be about 3V or even 2.6V is ok. Also try a hard reset, by taking the main battery, RTC/bios batteries out and leave them disconnected for 15min, then reconnect both batteries and try to boot the laptop and see if it boots?

    If not then you have to revert to this laptops Crisis Disk method of a bios recovery, but and as Acer describes in the SG "this action is not sure to fix the BIOS 100% successfully (EX: when the PEI region part is crashed, the crisis recovery cannot fix the BIOS" as there may be other faults with your laptop. or even that you might have to replace the bios chip with a new and programed bios chip with the last SF114-34 bios version:1.14 Date:2022/10/21 "Updates EC version",

    Be Warned: if you have no experience in building and/or using a Crisis Disk then take your laptop to an experienced tech who has experience and also can analyse/fix the problem or the damaged bios chip or replace the bios chip with a new one.
