Don't ask how to hack password. (BIOS Passwords)

We are know that CMOS, which stands for Complementary Metal Oxide Semiconductor. The CMOS chip is like the alarm clock in your bedroom that always remembers the time even when the power goes out. Like your alarm clock, the CMOS chip has a small on-board battery that provides power, so it can retain all the information necessary to start the PC properly. If something goes wrong with the battery, the CMOS loses all these settings, which causes your computer to effectively "lose its mind."
CMOS chips pass information to the BIOS (Basic Input/Output System) when the computer is turned on (called bootup). CMOS stores information such as boot order (the order the computer looks for information, such as A drive first, C drive second, and so on), real-time system clock, calendar settings, hardware passwords, hard drive configuration settings, and the installed memory (RAM). Essentially the CMOS chip stores data for the BIOS so that a computer can boot up properly.

Now the problem is the laptop has no cmos setting at all. It can boot but do nothing. Any expert can get the cmos back using any program or software.
