Question Can't find CMOS reset jumper on Lenovo Thinkcentre M58 motherboard

[itm]

I need to reset the CMOS on a Lenovo Thinkcentre M58, but I'm not sure which jumper to use, and I can't find the correct manual for the motherboard.
I've located three sets of jumpers:

• BIOS_WP / THER_HD - these are 3 pins aligned in an "L" shape
• CMOS_HW1 - a set of 3 pins
• CMOS_HW2 - a set of 3 pins

Can anyone advise re. which one to use to reset the BIOS/CMOS?

When in doubt, simply disconnect from the wall and display, then remove the CMOS battery and then press and hold down the power button for 30 seconds. Replace the battery after 30 mins.

I've just tried removing the battery, waited half an hour, and rebooted. Unfortunately it hasn't resolved my problem, which is....
I get these errors from the BIOS on startup:
162 - Configuration Error - Default configuration used
CFG Error: TPM Initialisation failed
198 : System Security - Unauthorized BIOS Update Attempted
197 : System Security - Unauthorized CMOS change detected

Press F1 to Setup. F2 to resume.

Neither F1 or F2 do anything - the system just remains in this state.
