Re: a cleared bios
As I've mentioned a few times here..you'll need to load the bios from a disk, most likely a cd..by going to the link I sent you, and burning it into a cd..slide that into the computer, and restart it..

I can't find a decent manual for your laptop but there will be 2 pins on the motherboard that will say BIOS Clear. Short these 2 pins and turn the computer on. This is the only way to bypass the BIOS password. This operation will clear the BIOS and reset to factory defaults. After the BIOS is cleared, turn the computer off and take off the short.
There should either be a physical switch somewhere on the side of the laptop or by using the FN + a certain key to activate it. Look at the F keys for an image similar to wireless then try that.
If the above does not work, its probably turned off in the BIOS. Access BIOS and turn it on.

A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.
B. By Using Software:
I have found that BIOS/CMOS Password Recovery Tool is the most effective.: BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds
YOu can reset bios password with 2 method. (1) open back cover of
laptop then find motherbord .Pull cmos cell from motherbord for 15
minutes then again put it in it's position .then it not ask for
password. (2)You can clear password with jumper settings find jumper on motherbord named clear cmos it has 3 pin .1-2-3 Put jumper in 2-3 position then again put it in 1-2 position then check . Let me know if you need more assistance. Thanks.
If you cannot access the machine after if has been powered up, it is
still possible to get past the BIOS password.
The BIOS password is
stored in CMOS memory that is maintained while the PC is powered off by
a small battery, which is attached to the motherboard. If you remove
this battery, all CMOS information (including the BIOS password) will
be lost. You will need to re-enter the correct CMOS setup information
to use the machine. The machines owner or user will most likely be
alarmed when it is discovered that the BIOS password has been deleted.
On some motherboards, the battery is soldered to the motherboard,
making it difficult to remove. If this is the case, you have another
alternative. Somewhere on the motherboard you should find a jumper that
will clear the BIOS password.
If you have the motherboard
documentation, you will know where that jumper is. If not, the jumper
may be labeled on the motherboard. If you are not fortunate enough for
either of these to be the case, you may be able to guess which jumper
is the correct jumper.
This jumper is usually standing alone near the
battery. If you cannot locate this jumper, you might short both of the
points where the battery connects to the motherboard.
If all else fails, you may have to clear the BIOS password by
resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your
Many RTC's require an external battery. If your RTC is one of this
type, you can clear the BIOS password just by unsocketing the RTC and
A hard drive password can only be removed by the person who knows the password because then it can be cleared thru the BIOS.
Otherwise the only other way around it is the buy a new hard drive so it doesn't have a password and you can then reinstall the operating system on the hard drive and then put the drivers on it and any other programs that you want on it.
Usually DELL Latitude or Inspiron passwords are storedi n eeprom memories
that has to be read or writen to remove / bypass the BIOS password!!! Password
generate a hash code that will appear after 3 wrong password attempts and it
has a 5 digit decimal format "xxxxx" You can get the hash code by
pressing F2 or F10 when you turn on the laptop to enter Bios and then when
password prompt appears hit F12 to get the hash code.
You can generate a unlock code or master password with the service tag "xxxxxxx" 7 digit, this code appears at the password promtp screen or at the bottom of the laptop with a white sticker.
I got Latitude D620 Bios password Unlocked at http://www.laptoprebirth.com
They can calculate a master password with the hash code. Hope
