The official method is to contact Dell Technical Support. Dell Technical Support will request the Service Tag and Express Service Code from the bottom of the Latitude. If the current user is not the original Latitude owner, Dell will transfer the used Latitude's registration from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.

  • For most Dell Dimension desktops, the steps to reset a BIOS password and clear all CMOS settings are:
    • Locate the 3-pin CMOS password reset jumper on the system board.
    • Remove the jumper plug from pins 1 and 2.
    • Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
    • Replace the jumper plug on pins 1 and 2.

Try the backdoor password: Dell

The another method is: by Using the Motherboard Jumper: In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off, and remove the battery and power cord
( if it is a laptop ) before you continue.

Here is a picture how it looks like:

The default setting is:pin 1 to 2, to clear cmos: 2 to 3.

Best of luck :-)

Dell d340. need to enter admin password in bios to reorder boot sequence to accept usb first - its locked and i cant remember password. tried removing cmos battery and replacing but no good. help!


Try the backdoor password Dell

With a PSWD Reset Jumper Step 1Open the access panel to the password reset jumper if your Dell laptop has one. Consult your manual for the access panel's location. Some access panels have a tab you slide, while others are held in place with a screw.
Step 2Pry the plastic cover off the reset jumper with your fingernail. The reset jumper is a small pin port labeled "PSWD" with three pins. Put the plastic back onto the jumper over pin 1 and 2 instead of 2 and 3. Wait 90 seconds.
Step 3Pry the plastic off the reset jumper again and place it back onto the number 2 and 3 pins. Turn the laptop on. Repeat step 2 if the password is still present. Leave the plastic clip on pins 1 and 2 for a longer duration than last time.

Without a PSWD Reset Jumper Step 1Locate the reserve battery, also known as the CMOS battery, if your Dell laptop is not equipped with a password reset jumper. The CMOS battery's location varies among Dell laptop models. Consult your manual for the battery's location on your specific Dell laptop model. Many Dell reserve batteries are located underneath the main laptop battery. Remove the main battery and look for a sticker under it with instructions on removing the secondary CMOS battery.
Step 2Remove your Dell's reserve battery per the instruction manual or sticker located under the main battery. Removing the reserve battery resets the laptop's BIOS password. Wait 90 seconds, then replace the reserve battery. Reconnect the main battery.
Step 3Press the "Power" button to turn the laptop on.

You maybe able to remove the password and set the BIOS back to the factory defaults by removing the CMOS battery for 20mins. Replace the battery and go into the BIOS setting to set the Date & Time.

BIOS passwords for dell laptops require you to contact Dell technical support if you forget the password. they will generate a master password depending on the type of BIOS password. you cannot reset it by removing the CMOS battery.

Hello i need the master password to clear cmos for laptop dell 1440 the service tag (s/n) is :4WMP7L1 thanks


I don't think there is such password.
You could contact dell and ask for the password if there is.
If not then best option is to remove and reseat the CMOS battery.
Contact Dell and tell them to provide you with the steps to remove and reseat the CMOS battery.
It will reset all the BIOS values.

FORGOT BIOS PASSWORD DELL LATITUDE E6400 HELP ME PLEASE...!!! THX


The above solution does not work on an E6400. Any fix regarding removal of battery, shorting pins together, etc does not work. However, what does work is to use the Dell Asset/Service Tag BIOS Reset Tool that is available on Torrent Sites. Boot the CD image and when you are asked if you want to delete/change the service tag select "Y". When asked for the new service tag number re-enter your current service tag. Then the tools erases the BIOS and inputs the new service tag. A by-product of this process is that the BIOS master password is removed from the BIOS.
