In laptop, CMOS password is saved in password chip or Flash
ROM. So even you refresh BIOS, you still couldn’t crack CMOS password. If you
really have forgotten password, you could send it to computer repair shop. But
there is such principle said that, don’t repair laptop when password forgot.
Now the passage mainly introduces that, how to remove laptop CMOS password when you still remember supervisor password, user password and
hard disk password. Now take ASUS M2N laptop as example, start laptop and press
F2 to enter CMOS setting program. Now it will ask you to type in supervisor
password before CMOS setting program interface appears. Move to “Security” menu
option with direction key.
Turn to “Primary Master HD Password” option with direction key,
press Enter and “Enter Password” dialog pops up. Now don’t type in any
characters and press Enter directly. “Password Uninstalled” message prompts you
and then press Enter again to clear hard disk password.
2. Clear User Password
Move to “Clear User Password” option, and press Enter. Click
“OK” on pop-up dialog and press Enter to remove user password. At this time, you
would see in this screen, “User Password” option shows with “Not Installed”. You
would find that, even though you forget Windows user password, you still could enter
CMOS to clear user password with supervisor password.
3. Remove Supervisor Password
Go to “Change Supervisor Password” option, press Enter. Don’t
type any characters in pop-up “Enter New Password” dialog. Press Enter directly
until “Password Uninstalled” prompting message appears. Press Enter at last,
and supervisor password would be removed. Now you could find that “Supervisor
Password” option is showing “Not Installed”.
