For that you need to reset factory defaults settings for bios.
For reset bios u have to open back side of your laptop then u find motherbord circuit there.
pull cmos cell on motherbord for 15 minute then it reset to defaults.
Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear"
It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset.
then again set it in 1-2 its original position.
Then it not want password.

How to clear momory from setup screen


The setup screen has no way of clearing the computer memory. The setup screen will allow you to change things as far as devices, dates, times, passwords.

Why would you want to clear the memory anyway? Exactly what is it that you are trying to accomplish?

I want to unlock my Dell Latitude D630 Laptop


Dear Sir,

It required us to actually call Dell, give them the laptop's service tag number and they would give us the key combination and "code" needed to unlock it and clear the passwords. Dell is 1-800-822-8965 begin_of_the_skype_highlighting 1-800-822-8965 end_of_the_skype_highlighting (US).


Thanks For Your Time,

How to unlock it without administrators code


if you're running XP, you need to change the boot preferences to CD first, burn a CD with a particular linux kernel on it, specifically designed to blank an Administrator password. boot the CD, follow the prompts, change the password to a blank one, writing a new one in doesn't work because of MS security. after the kernel has done its work, restart. when you get to the login screen DON'T LOG IN JUST YET. press ctrl-alt-del twice should take you to the old username/password prompt. type in Administrator as user, nothing as password. bam, its yours. ^^
