Problem after BIOS update

[Notmyrealname2]

Hi, a few days ago, I updated the BIOS from J61 v03.52 to J61 v03.96Rev A and didn't seem to have any problem in doing this.

Today, when I tried to enter the BIOS using the Esc key (1st attempt) then using F10 (2nd attempt), nothing happened, except that it booted up in Windows as usual.  Both of these keys would normally let me get into the BIOS with the older version.   I also tried it using the F2 key. 

After another few attempts, I decided to try and roll back the BIOS by holding down the Windows and B keys while powering on.  Again, it went straight into Windows.  It's as if the keyboard is not being detected during the initial stage of the boot sequence.

My next effort was to do a System Restore to a date just prior to the BIOS update.  I then ran msinfo32.exe but this showed that I still had the updated BIOS version and for some reason, I now am not able to open Google Chrome which, at this stage, is a minor annoyance. Fortunately, Edge had no issues.  Unfortunately, I still can't get into the BIOS settings.

Can anyone suggest how I can get back to accessing it?  Thanks in advance.

FIXED!   So, today I managed to find the problem and discovered that it was my own stupid fault.

Prior to updating the BIOS, I had been having some issues with my keyboard where occasionally, the first few keystrokes did not appear on screen. I wasn't sure if the keyboard itself was to blame or if it was the PC causing the issue. I had a spare wireless keyboard so decided to plug it's receiver into a spare USB socket on the back but left the old one working and somehow, the issue I had been having went away and I forgot about the extra receiver. What I discovered was that this receiver was preventing my regular keyboard from being detected until after Windows had booted up, after which it worked okay. Here's how I found the problem.

I entered the Startup Settings from Windows so that I could use Boot Logging but when I tried selecting any of the numbered options, the keyboard would not respond. This had me wondering at first then I remembered about the USB receiver and removed it. Bingo - my keyboard was back working normally so I rebooted and thankfully was able to bring up the BIOS screen as normal. So, the lesson learned is to only have one wireless keyboard receiver plugged in to the USB ports at any one time. I hope this experience will be of some help to others in the future.
