Generally, in almost all current portable systems, the bios password is stored in Non-Volatile RAM and cannot be cleared by removing the CMOS battery.
If a Dell, you can contact tech support for a Master Password, other manufacturers have other methods

Forgot my password


In computing, BIOS (basic input output settings) refers to the information stored regarding a computer's hardware configuration, the system date and time and any applied password. This information is known as the BIOS or CMOS settings--the BIOS is stored on a small battery-powered semiconductor chip known as the CMOS (complementary metal oxide semiconductor). Having a CMOS or BIOS password restricts unauthorized changes to the system's hardware configuration and, in some computers, may even be required for booting. A lost password may be reset by removing the CMOS battery, clearing the motherboard jumper or using a software-based password cracker.

1.Shut down the laptop and unplug its power cord from the wall outlet. Remove the battery cover under the laptop and gently raise the battery from its dock. Unplug any peripheral devices with a live power source connected to the laptop, such as a modem or printer.
2.Locate and remove the CMOS battery. Refer to your user manual or visit the manufacturer's website for your laptop's architecture. Follow manufacturer recommended procedure to access and remove the CMOS battery. Depending on make and model, this procedure may be more involved for some laptops and not others. The CMOS battery is a flat circular shape and resembles a watch battery.
3.Wait 30 minutes and then put the battery back in. This will erase all information stored in BIOS. Assemble the laptop, making sure you leave no loose connections. Power up the laptop and press "F1" when you get the "CMOS cheksum error" message. Type in a new password.

Clearing CMOS Jumper

1.Turn off the laptop and access the motherboard following recommended procedures.
2.Locate the jumper in the motherboard. If you do not have your motherboard documentation, locate a single jumper near the CMOS battery. In some laptops, the jumper may also be labeled in the motherboard. Put the jumper setting to "Clear" and reassemble the laptop.
3.Turn on the computer and hit "F1" when the "CMOS checksum error" message is displayed. Navigate through the BIOS settings interface to load default settings and apply a new password.

Using Password Remover

1.Download a software-based BIOS password cracker. There are numerous free programs able to recover or delete CMOS or BIOS passwords from virtually all motherboard brands. Download the file from a trusted source and save it to the desktop.
2.Burn the installed file to a CD using image burner software. Insert the CD and access the password remover tool.
3.Note the password or use the program to set a new password.

I hope you find it very helpful. Thank you.
