     Which BIOS update did you attempt to install in your E5-473? Give us the version number? As the BIOS flash is a very simple process within windows but you have to take precautions and your windows operating system has to be uninterrupted during the BIOS flash, also, the anti virus has to be disabled and no software has to be running and/or any dangers of a power mains interruptions are also required because and if you get any of these factors interfering with your BIOS flash it will be corrupted and will brick your laptop.

    The last BIOS for your E5-473 is the v1.13 and dated 2016/05/10 "Release Note: Improve system performance" and "How to update BIOS
    Click A4WAB113.exe" which is really simple.

    Anyway, if you haven't done that and you bricked your laptop then its a problem and you could do a "BIOS Secure Flash Utilities see under Systems Utilities > Flash Utilities' which needs to be done, have a look at this section from the E5-473 service manual (that I'm including for you below) of how to do this, I'm including this for you so that you know exactly how to do this step by step and all other people that have an Aspire E5-473/G/T/TG models that need a guide from the official Acer guide. It could also be a BIOS chip problem as its damaged and can't be updated? You could also take it to an experienced technician that specialises in BIOS chips and all electronic repairs like and have a look and/or send your motherboard to NorthridgeFix or their Mail In Service who are experts in this regard and will fix your BIOS problems.

    Note:
     I take no responsibility if you attempt this wrongly and if you brick your laptop as I suggest that if you don't know how to proceed with this procedure you "DON'T ATTEMPT IT" as Acer warns you "Upgrading your system BIOS incorrectly could harm your Acer product. Please proceed with caution" as this could do more damage than fix anything if you do it wrongly! Good luck.

    There is NO OTHER BIOS version for your Aspire E5-473 and from 2017 the LAST ONE from Acer is the 2016/05/10 version 1.13! If you installed and did an .exe BIOS flash file that was a none OEM Acer BIOS and not like the type and like the version 1.13 then your E5-473 will not be able to update your BIOS. If you did a Dos BIOS flash (which you shouldn't do) then you could have corrupted your BIOS and it needs the "BIOS Secure Flash Utilities" to be done.
