How to reset market password on desktop compaq presario 5204

I was given your desktop compaq presario 5204 a couple of years. I have never tried to use it until today so I can't ask the person who gave me the password.  When I try to start it I get a screen asking the power on password. How to reset it or remove? I want to donate it to the model railroad Club, I belong to, but it is useless this way.

Disconnect the PC and open the case. Remove the RTC battery (money and the size of a dime), press the power button. Look near the battery for a jumper labelled clr cmos or something close. Remove the jumper and then put back in the same position.

Please post your results.

I couldn't find any information on the motherboard, but it's probably like virtually every other motherboard.

Best regards
ERICO
