If you pull out bios battery only and start with both main battery and charger will it start?

If not then problem is with main battery or adapter in general

If you start with adapter only and it does it means problem with main battery

Bios battery voltage must be 3 or greater for laptop to start in normal way, without it laptop will boot at 3rd attempt after restart

Confirm problem with main battery or not by start only with adapter plugin

ok, tested

AC connected - bios disconnected / doesn't start
main battery connected - bios disconnected / doesn't start

main battery disconnected / ac connected / bios connected - doesn't start
main battery connected / ac disconnected / bios disconnected - doesn't start

bios battery voltage / 3.1v

What do you mean by bios disconnected?? Which kbc it uses?? Check RTc section like RTC_RST#/SRTC_RST#. Look for jumper marked on mb "cmos1" or "me1"
