To reset the BIOS password from a Dell laptop you need to remove the password jumper from the motherboard. You need to follow a few steps in order to reset the password. After you locate the 3-pin CMOS password reset jumper, remove it and plug from pins 1 and 2. At first place the jumper plug on pins 2 and 3 and wait approximately for 5 seconds. After that replace the jumper plug on pins 1 and 2 and you are done.

The location of the password jumper on the motherboard can be found in Optiplex User Guides.
