Can't Use Keyboard in BIOS

Hi Guys !

I have a problem, after a looong time.

System

Dell Latitude 3440
BIOS Version: A11 (Updated from A08)
OS: Windows 10 & Elementary OS

Scenario

I updated the BIOS yesterday. I was able to change BIOS settings after the upgrade as well. Now, I can use the F2 key to get into the BIOS but I cannot use the keyboard once the BIOS screen appears. I can boot into both Operating Systems. Keyboard works on both Operating Systems.

Have you come across anything like this before?
