My laptop is Acer Aspire V5-473PG
and I used windows 10 Pro 64-bit
. And my battery is already dead around 1 year. Now, when I turn on my laptop, it always shows something like this : Boot media is missing, Please insert bootable media...
.
But, I can boot with legacy boot mode, not UEFI. So, I think my UEFI firmware has some problem and I want to upgrade my UEFI. So, I download correct BIOS for my laptop from acer website and it contains only one executable file.
When I run that file to upgrade BIOS, it shows Please insert system battery
and I can't upgrade.
I already search many ways on internet, but not working. So, please anyone help me how can I upgrade my bios without battery.

Just got thorugh this "upgrade bios without battery" hell on my Acer E11.
The following worked for me:
%userprofile%\AppData\Local\Temp
, there should be somewhere a temporary directory containing the extracted files from the EXE file (for me it was 7zS4A88.tmp)Some additional notes:
