WinFlash doesn't update Bios when battery is removed

I have laptop ASUS X556UQK and it's battery is removed because bloating (Swollen battery).

I'm trying to update Bios from version 312 to 318 using WinFlash and the downloaded Bios file version 318 from ASUS site.

Here what i did by my side in trying to update the Bios:

1. By following the classic steps to update Bios (throught advanced setup and USB flash), it says Ez Flash-Check System Power Error: please check battery is connected and remaining capacity is more than 20%. (this picture is NOT mine but shows the exactly error message )

2. I tried the alternative methode via terminal

   "C:\Program Files (x86)\ASUS\WinFlash\WinFlash.exe" /nodate

3. When the system display that i can not update the bios because there is no battery, on my keyboard i type the word "risky".

none of the above steps helped me to update bios without battery or bypass the warning please check battery is connected and remaining capacity is more than 20%.

Is there any other way to update my laptop's Bios through WinFlash without battery connected?

You have to have a battery inserted because if you lose power duirng a BIOS update your laptop will become a doorstop. Buy a replacement battery and then you can do the update.
