Close to the CMOS battery there will be a BIOS jumper. This jumper usually is colored dif. from all the rest and is labeled commonly (but not always) "J4". The CMOS jumper usually is a 3 pin lead setup and normal operating mode most of the time is with the jumper on pin 1 & 2. If this jumper is on the first and second pin you are going to then move it to the second and third pins and let it sit for about 30 seconds (or place it on pins 1 & 2 if it originally resides on 2 & 3). Once you have done that you will then replace the jumper back as you found it and reconnect all your input/output devices. Power on your computer, boot into BIOS, and use auto detect for your hardware specs. Most of the time you wont have to touch anything setting wise in the BIOS (if its good firmware it detects everything by itself).

    removing the CMOS battery but you left out 1 important step. Plug back in the AC cord with the CMOS battery still removed. It will power itself back on giving you the option to hit F1 to save changes. During reboot, plug the CMOS battery back in and you're all set, no more power on password.
