I removed the CMOS battery, there is no clear CMOS button, will have to
try and see if there's a clear CMOS jumper.
Any suggestions appreciated

short the battery terminals while it is removed.

does capslock LED respond to capslock key?

I'd be surprised if that worked as there's usually a series diode to
prevent reverse charging of the battery under fault conditions (or that's
the way it certainly used to be done).

Note that Intel reference schematics are not known for their "realism"
and real circuits have slightly different details. For example, the
Port Angeles on this particular schematic is pure imagination and
not real (not a proper SuperIO). Still, you can use this little
circuit, to have a discussion about the Clear CMOS jumper and
what good (if any), shorting the battery terminal would have.
TLDR
Can you please state succinctly the point you are trying to make.

I think he its trying to say 'taking the battery out and shorting its terminals may not work (because there is a diode in there) and may cause damage (because there might not be a resistor or diode in there)'.
There are usually some shortable header pins or in extremis, simply removing the battery and letting the data decay from the CMOS should sort it all out.
Of course these days the data is in flash, and wont decay ever. Only the RTC will stop without a battery
