How to check BIOS version if laptop won't turn on?

My laptop recently randomly turned off while I was using it. Now it will no longer turn on.

I noticed the charger LED blinking and the 4th and 10th light were red, I think this is a CPU issue.

I reached out to support and they said they need my BIOS version to help me, but I don’t know how to check that without being able to get to the BIOS.

Any advice?

If you never upgraded the BIOS, then you can probably guess which version you have based on which batch you were in.
