The CMOS battery is located in the CDROM bay. The leads from the battery (black&red) run up the motherboard and plug in next to the ribbon cable for the touchpad. The password is stored on the small (1x1.5") chip that is plugged in next to the modem. The printing on my chip states "TCPA SECURITYB" Undo the screw, remove and toss the chip, and unplug the leads from the battery. Also pull the hard drive, battery and unplug the AC adapter. Set the laptop aside and go have a smoke. Come back later (I waited 15 minutes) and plug in the AC and press the power button (do not plug the battery leads back in or reinsert anything else, just press the power button) This will flash the BIOS and ask you if you want to save. Save the settings and power back down. Put the laptop back together and enjoy, password free.
