100% battery drain after update to Bios 1.15.0

Did anyone have this problem:  I installed Bios 1.15.0 last week.  My laptop was fully charge.  I work for an hour or two (plug in AC) and then turned off my laptop and unplug it. 

Today, I plug it in and turn it on, and found that the battery was completely drained.  I look in the windows event viewer to verify that the pc did not start by itself but nothing happened between the time I turned it off and the time I turned it on. 

In the bios, it says the battery is in excellent condition.

I never had any problem with the previous bios.  I wanted to downgrade the bios, unfortunately, Dell prevent it. 

I am charging it again to 100% and let it rest for another week to see if the problem occurs again.

Are you referring to the m15 R4?

If yes, why would you install the old December 13, 2022 BIOS 1.15.0?

Why not install the latest February 6, 2024 BIOS 1.20.0?
