Issue:
Generic BIOS
password listings.
Additional
Information:
If a BIOS
password is forgotten in some cases it may be possible to use a generic
BIOS password to bypass the unknown password. Or by using a generic BIOS
password you may be able to change the password to a different password.
Cause:
If a password is
mistakenly forgotten or set without your knowledge it may be necessary
to use a generic password to bypass or change the password.
Solutions:
Below is a
listing of generic passwords for the different types each of the major
types of BIOS.
Note: It is
important to realize that these passwords do not work on all types of
computers and/or BIOS chipsets. If you are unable to bypass or change
the password by using these passwords please refer to the document
CH000235 for how to
manually clear the unknown password.

SOME COMPUTERS WITH TOSHIBA BIOS
Hold down the
Shift key as the computer is booting
Question:
How to clear an
unknown BIOS password.
Answer:
If you have
mistakenly lost your password to the computer BIOS password or you
receive a password at boot you will need to clear the BIOS password by
one of the following methods.
Precaution: When
inside the computer please be sure of the potential of
E S D.
·
Try generic BIOS
passwords. A complete listing of these passwords can be found on
document CH000451.
·
On the computer
motherboard locate the
BIOS clear / password jumper or dipswitch
and change its position. Once this jumper has been changed turn on the
computer and the password should by cleared. Once cleared turn the
computer off and return the jumper or dipswitch to its original
position.
The location of
the jumpers or dipswitches may vary, however here are general locations
where these jumpers / dipswitch may be located.
1.
On the edge of
the motherboard -
Most jumpers are located on the side of the motherboard for easy
accessibility, verify by looking at all visible edges of the
motherboard.
2.
By the CMOS
battery - Some
manufactures will place the jumper to clear the CMOS / BIOS password by
the actual CMOS battery.
3.
By the
processor - Some
manufactures will place the jumpers by the processor of the computer.
However note that in some cases these jumpers will be to change the
processor and not the password.
4.
Under the
keyboard or bottom of laptop
- If you are working on a computer laptop the location of the dipswitch
(almost never a jumper) can be under the keyboard or on the bottom of
the laptop in a compartment such as the memory compartment.
5.
Other visible
location - While it
is possible that the jumpers / dipswitches may not be in a visible
location, most manufactures try to make things easier by placing the
jumpers / dipswitches in another visible location.
Additionally,
when looking for the jumper / dipswitch the label of that switch can be
anything however in most cases will be labeled CLEAR - CLEAR CMOS - CLR
- CLRPWD - PASSWD - PASSWORD - PWD.
·
On the computer
motherboard locate and
remove the CMOS battery for at least 10 minutes allowing the computer to
loose its information. Note: this will not work on all computers.
·
If your
manufacturer has a bypass password this can be entered and allow you
access to the BIOS and or computer. Because of the security risk of a
bypass password generally only older computers will have this option. In
addition it is likely that this information will only be able to be
obtained from the computer, motherboard or BIOS
manufacturer.
·
On the computer
motherboard
locate the CMOS solider beads and jump the solider beads to clear the
password. The identification and location of these solider beads can
vary and if not available in computer documentation is generally only
obtainable through the computer manufacturer.
If one of the
above solutions do not clear the password or you are unable to locate
the jumpers or solider beads it is recommended you contact the computer
manufacturer
for the steps on clearing the computer password.
