You can remove or change the Window's User or administrator's password. You need access to a computer with Internet access to download the Hiren's Boot CD and burn it onto a CD. Then insert this CD into the laptop/computer and boot up the laptop/computer with the Hiren's CD and follow the instructions. There are very useful utilities CD and it a Linux boot CD which contains quite a lot of Utility programs including a password removal program.

SOURCE: 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.

SOURCE: No sound in my Dell Inspiron 6400 laptop

If the issue is no sound after reinstallation of Windows, then your issue is most likely a driver issue. Many items in the system will function with native windows drivers but the audio on a I6400 is not one of them. Installation of drivers in the correct order is critical to Dell portables functioning correctly. Correct driver order is:

Notebook System Software.
Chipset Utility
Video Driver
Audio Driver
Modem Driver
Network Driver
Wireless Driver
Touchpad Driver
Quickset Utility

All other applications and drivers (MS Office, Printer driver etc)

This system is also equipped with Media Direct capability. For Media Direct to function, the system's HDD must be prepared using the Media Direct installation CD, then WIndows installed, then the Media Direct application. If you have no plans to use media direct, this can be skipped (Most people do)

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
