How to remove or delete Primary Password Dell Latitude C400 laptop (I have password)

If you are the dell registered owner then contact support  (with your invoice details at hand) and ask for a master password.

I have a master password... try again!

I assume you are trying to delete a known bios password.

Try holding down the "Ctrl" key when pressing "enter". Don't know if this applies to your model specifically, but some systems require this to enter a blank in the bios. Worth a shot.

Yes I'm trying to delete a known bios password do I dont have to enter it every time I boot

Tried the Ctrl  enter but no avail

Thanks for helping

Hi Peakslayer,

I did read your post, and also read that you entered the primary password 3 times and your getting an error beep. So most probably the password is changed or incorrect. Hence you will need to contact Dell Technical support.

Thank you

Royan...

Did you not read my post?

I have the password!!!

If you have the master password, enter it.  Then go to the password change field and enter nothing (twice).  Save.  The password is now gone.

Nope on "hit enter twice" Still get error beeb. Even pulled the HD ad removed the cmos battery. Weird

Hi Peakslayer,

Welcome to the Community. To remove or change the Bios Password you will need to contact Dell, and verify the original owner of the system, after which they will be able to give you the Bios password so you can remove the existing password.

Thank you

UPDATE: it was running A11 for bios version. I updated it to A12 and it will now let me change/delete the password. How weird. Thanks for the help!
