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.
![Update Bios Acer Update Bios Acer](/uploads/1/2/5/2/125212158/564424179.jpg)
The following worked for me:
- Download the BIOS update from Acer site (ZHK116.EXE)
- Run the downloaded file, you will get an error like 'No battery' or 'Low battery', stay on the error dialogue (!)
- Navigate to your current users temp directory (e.g. Users/<username>/AppData/Local/Temp), there should be somewhere a temporary directory containing the extracted files from the EXE file (for me it was 7zS4A88.tmp)
- Save the contents of that temp directory somewhere (you can then close the error dialogue, the temp files will be removed)
- Open the file platform.ini with a text editor and search for the key 'AC_Adapter'
- Change parameter BatteryCheck from 1 to 0 or just leave it empty (this disables battery check during BIOS update preparation!), save the file
- Run InsydeFlash.exe in the same directory
- That's it, bios update should start now
Some additional notes:
- Extracting the ZHK116.EXE manually via 7zip did not work because for some reason the result does not contain the BIOS flash file isflash.bin (ROM file)
- Opening the ZHK116.EXE with 7zip and modifying the plattform.ini file out of 7zip did not work either, you cannot save the file
- Updating BIOS via a bootable USB device having a FreeDOS on it did not work getting the same 'battery' error (seems that the check is also done in DOS)

I had an ACER Aspire V5-571P with the same problem.
Following on from the previous answer, my *.exe file was called 'VA410218.exe' and extracted to 'Users//AppData/Local/Temp/7z????.tmp' directory and contained the files (Which as stated will probably get erased when the cmd window closes .. so keep it open) and copy them to somewhere useful. .
Alternatively, open the *.exe as an archive using 7-zip (or WinZip?) and extract them directly to somewhere.
There will then be your 'Somewhere' directory containing:-Launch.batUpdate.batBIOS.capcmd.exeWinFlash32WinFlash64TdkLib.sysTdkLib64.sys
(Or something similar)
The important one is Launch.Bat which actually calls the WinFlashxx program.Edit this and look for
WinFlash32.exe /bcp /sd /ver /cvar /v /endkey /silent /bbl /cac /cbp 30 / ..
or
WinFlash64.exe /bcp /sd /ver /cvar /v /endkey /silent/bbl /cac /cbp 30 / ..
Depending on your operating system.
The switch /cbp 30 is the minimum battery level required before the program stops. Either delete this switch or change the value to something lower.
Then execute the batch file 'update.bat' (as Admin) and voila. No battery checking.
This is not for the faint hearted and you must 'absolutely not' lose power during the flashing process. (UPS?)
Don't blame me if it ends in tears.
PS, it did not solve my battery problem (I have gone through 4 now, some only lasted a week)
