I would go for Zorin OS Lite on it but...
I cannot gainsay it, but I also cannot think of anyway that Zorin or an Update on Zorin could nuke the BIOS.
Windows OS can access BIOS - However, Linux generally can or does not.
So, if I can't get into BIOS or boot to USB or anything, what can I do?
The only thing I can find on a search is to try using a Wyse Keyboard (If you are not already...)

This is particularly unusual... I have never seen a computer disallow access to the BIOS unless the motherboard had component failure.
I'm not saying that yours has...
Wait ... what ? ... They can ? 
Absolutely, Yes. They Can.
And if you look pretty deeply into what TLP can do, it will raise all the hairs on the back of your neck, the back of your legs and probably most of the hairs on the front, too.
Which is exactly why I find the demand that TLP be active for Win 11 to be so very, very disturbing...

I have a Toshiba where I have to hold F2 even before pressing the power button. Only then does it let me into BIOS. Royal pain.

Still working on this guys, I'm going to try a new CMOS battery today although I don't see that working. If I remember correctly the update that I tried was a Dell driver update, IDK if that helps.
For clarity, you mean it was not a Zorin OS Update? When you said "after updates" it seemed you meant the Zorin OS System Updates.
It was a Dell specific package? Can you give more details on this? This may well be the clue we need.
It was a Zorin update, but it said something about Dell. I wish I could remember exactly what it was.
I looked a little deeper into the meaning of the lights, on my above picture, it's 3,3 bios recovery 1, recovery image not found.
I also replaced the CMOS battery to for sure eliminate that as a possiblity. No luck.
According to Dell it is a bad power supply... it won't boot because it's not being charged.
Not comforting but makes sense, a little more than missing recovery which won't interrupt boot.

I think you will find that most computers need either a Function key to enter BIOS or the DEL key. On Dells its F2 as well.
Correct, I was aware of that. My point was that on some computers you need to hold the F2 even before one starts the PC.
OP stated they were unable to enter BIOS - I was asking them to try my suggestion.
Can OP confirm there is power from the power supply?

I changed power supplies, CMOS battery, tried all different combos of keys, still nothing.
Fn + F2 also tried to enter bios ?

My keyboard doesn't have Fn.
Looking back at your OP, If you are seeing 3 blinks, then 3 blinks (i.e. not 3 blinks then 1, or 3 blinks then 2), then that points to item "3.3, BIOS Recovery 1, Recovery Image not found" according to that diagnostics table.
To get into BIOS:
Have you tried repeatedy hitting 'F2' key immediately after switching on the power?
Other possibilities I have seen are press the 'Del' key or 'Ctrl + Alt + Enter' key combo.
Yes, I've tried all the combinations I can think of. All the recommendations on here and still nothing.
