I got a dell 6400 @ a garrage sale and it has a bios password,i need to clear it but i am not sure how to


BIOS passwords are usually set by IT departments and are intended for system security.

There are only 2 ways to fix this.

Get the password if purchased legitimately or replace the system board for $300-400 from Dell. There is no other way to bypass.

How do i unlock my dell laptop if i forgot my password


Is it the BIOS password or Windows password you are trying to get past. You can remove the battery on the motherboard and leave it out for 24 hrs or more and it should clear the BIOS password. The battery is a small round one like in a watch and it keeps power to a chip so your system wont lose the date/time and BIOS information. If its the Windows password you will have to use the adminstrator options or reinstall Windows completely and setup new passwords, eMail me at izzoaf@yahoo.com if you need more assistance.

Locked bios on dell inspiron 6400


Is there any clr cmos written on the board. The motherboards which do not have jumpers come with three point like solder on the board. You have to short first two manually with some wire.
If it is not there then you have to flush the bios with the bios flushing utility.

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

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.
