1) http://www.youtube.com/watch?v=5JqB4lkVxkA

2) Or take the laptop to the nearest authorized Dell repair shop; your ID, proof of purchase of laptop, and a credit card. Dell representative will ask Dell for a Master Password. Dell rep will then reset to NO password, or one you want. Dell rep KEEPS master password.

Removing CMOS Battery (Real Time Clock Battery. Also called Coin-Cell battery), will NOT work.

Go back into the Dell CMOS and try reseting all settings back to default. Restart and when it starts to boot, start tapping F12 to get to the boot menu. Try booting to the CD drive now.
***Please rate if this helps you or ask more detailed questions for more help. Thanks

if it is a cmos pass word or even the had drive password you need the password or it is not useable. there is a way to reset it but you have to take it all apart and go from there.Laptops have an unbrakable cmos password so if it is stolen it is unusable unless you have the password

you forgot to tell us what password.
Is it a bios password or windows password?


For Windows Password, As far as I know , there are two main methods to solve the windows password problem as follows:

1st Method:
Start system and when you see Windows Welcome screen / Login screen, press ctrl+alt+del keys twice and it'll show Classic Login box. Now type \Administrator\ (without quotes) in Username and leave Password field blank. Now press Enter and you should be able to log in Windows.
Now you can reset your account password from \Control Panel - User Accounts\.
Same thing can be done using Safe Mode. In Safe Mode Windows will show this in-built Administrator account in Login screen.

2th Method:
Windows password Recovery software:
for example: Any Windows Password Reset 7 . It is easy and convenient to use.

For Bios Password, also two methods.

1st method . Open you computer box and Discharge to the Board manually

2st method . use BIOS/CMOS Password Recovery Tool
