After performing a CMOS battery reset on my laptop, the BIOS stays the same. Does anyone have any solutions to this?

I unplugged my laptop from the power source. Then I opened it up and once inside, I disconnected the battery from the motherboard, and then disconnected the CMOS battery as well. I then held the power button for 30 seconds so as to drain any residual power that may still have been in the circuit. Then I let the laptop sit like that for about half an hour before reconnecting everything and rebooting the device. After the laptop turned on, the date and time was set to the time that I had shut down the system earlier, however, none of the BIOS settings had changed.
