SOURCE: reset bios password

If you are not afraid to open the box, the simple fix would be to remove the cpu battery(looks like a quarter) for about 30 seconds and replace, then boot up. At that point it will ask for information such as date and time, but then you can access the bios

SOURCE: Dell Inspiron 6400, asking for HDD password

Insert OS cd in drive and start reinstalling by selecting repair mode now once all files are loaded system will reboot when you see the Installing Devices progress bar, press SHIFT + F10
this will give you access to your account also you can reset all passwords
Now restart lappy and let the system boot normally without OS cd in drive
now you will come to old screen and previously configured desktop with all intact aplication and icons on desktop and it will no more ask you for password till you set a new one

Thanks and regards

Kindly rate this solution

Password Bios Losse


If you are the rightful owner dell will help you reset this.
but it will take some time.
or
you will have to remove the cmos battery (looks like a coin) under the keyboard and main battery
wait a few mins and try again.
if that does not work then only some techs knows what chip to short to clear.
like me.
