A BIOS password is one of
the important protection measures that could be used to make someone
stop powering up a computer system or making changes into that which
is one of the most sensitive areas. Many branded computer
manufacturers like Dell, IBM, HP etc. lock their customers out of
this particular area because they don’t want to their customer
should change anything and potentially damage the machine for which
they provide for warranty. Perhaps, when someone likes a computer
technicians or hardware enthusiasts, sometimes they need to make some
hardware changes to the computer so that they can access the BIOS.
So, BIOS is the first program before starting up your system even
before the operating system is booted.
Some steps to set a
BIOS password:-
Step 1: As you
start your PC press 'Del' or ‘Esc’ buttons
continuously and then you’ll find the BIOS screen in your system.
Step 2: When the BIOS screen will be
displayed, go to the Security Option, in that you will find
two more options for setting a password.
Admin Password– You cannot delete this
password in BIOS without knowing the password; this is only meant
only for advanced users.
User Password – You can delete this
password from BIOS even if you don’t know the password.
Step 3: To set the Admin Password write
the password in the space provided confirm the password then save it
and exit.
Step 4: To set the User Password either
provide the old password if it is enabled or write the new password
in the space provided confirm and save it then exit and your password
is saves now no one can start your PC without the password.
Some Methods to
Remove a BIOS Password:
1) Removing a BIOS
Password by using a CMOS Battery
This is one of the simplest method to remove a BIOS
password by simply removing the CMOS battery. A computer always
remember its settings and keep the time even when it is turned off or
unplugged because these parts are powered by a small battery inside
the computer called a CMOS battery. If you take out that
battery, the computer will forget a lot of its hardware settings,
including its BIOS password. This technique should not be performed
on Laptops if you are not an experienced in working with laptop
hardware.
But Anyway, Now open up the computer case use a
screw driver to locate the flat, circular and metallic CMOS battery.
Once you have located it, now you can observe how
the latches are holding it.
Make sure to power off the computer, unplug the
power cables and unplug any USB devices if they are powered. The
computer must not be able to get power from anywhere for this to
work. Take out the CMOS battery and wait for 10 – 25 minutes before
putting it back into its original place. The main reason for waiting
few minutes is that the computer still store power in its capacitors
even though everything is unplugged. The waiting period allows enough
time to get discharge.
Plug everything back in, powerup the computer and
enter the BIOS again. If everything goes well there should be no more
password left. But, In some cases If you get an uncanny error
messages during boot up now, then you will need to go to “Load BIOS
Defaults” in BIOS and save the changes to fix them.
If this method doesn't work out, try another method.
2) Removing a BIOS Password by using
the manufacturer backdoor password:-
On many of
the computers (especially old ones), computer manufacturers build the
backdoor passwords for their own technicians so that they can access
the BIOS when the hardware is being serviced. Here are some of the
ones that have been reported till now. So, you can now try a quite
few passwords before you find one that really works out.
* Remember-These passwords are Case
Sensitive.
