Answer 1

I was also looking for a Dell Bios password And found a solution at http://www.dellpasswords.com/ it worked for me maybe it will work for you too.

Answer 2

When your dell laptop display the error message:

( Invalid Password ) is because it is requesting a bios hard drive password and if the password came as invalid password it will shut down for one of the reasons:



1: typed the wrong password 3 times

2: typed the right password but forgot to press and hold Ctrl and then press enter twice.

3: your laptop's bios version has been updated and the password changed to a scheme.



Solution: http://biosremoval.com can provide to you both bios passwords if required.



remember that if you laptop has never been bios updated

you need a password from the older scheme.



if your laptop's bios password was recently updated then you need a bios password from the scheme.

Answer 3

are you talking about bios or hard drive password ?

if you are talking about bios I would tell you to remove the CMOS battery but it wont do any good,

I would tell you to short circuit the bios chip, but don't where it is,

you see, the bios password is stored on the Bios chip and it does not depend on battery power

so, your only hope is to contact dell tech support, they can come up with a bios or hard drive backdoor

password which will unlock your laptop in minutes !
