If you can't find the jumper to flash the BIOS or if such jumper doesn't exist, you can remove the battery that keeps the BIOS memory alive. It's a button-size battery somewhere on the motherboard (on elder computers the battery could be a small, typically blue, cylinder soldered to the motherboard, but usually has a jumper on its side to disconnect it, otherwise you'll have to unsolder it and then solder it back). Take it away for 15-30 minutes or more, then put it back and the data contained into the BIOS memory should be volatilized. I'd suggest you to remove it for about one hour to be sure, because if you put it back when the data aren't erased yet you'll have to wait more time, as you've never removed it. If at first it doesn't work, try to remove the battery overnight.
Important note: in laptop and notebooks you don't have to remove the computer's power batteries (which would be useless), but you should open your computer and remove the CMOS battery from the motherboard.

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 :-)

During the boot process you will see on the screen to press a certain key to enter setup
Press and hold that key during the boot up process to enter BIOS
after you make any changes in BIOS press Esc then press the F10 button save to cmos to restart
cmos is located in BIOS

Your bad luck ... Id dell and IBM bios password is saving in a small non-volatile memory. So you cannot clear it by a jumper or CMOS battery removal. Specialized people can only do the same (contact laptop motherboard repairing vendors)

Got a dell studio 1735 lost bios password


The jumper should be right next to the CMOS battery. It is also completely possible that simply pulling the CMOS battery would reset the BIOS enough to get rid of the password.

I have a Dell 6000m laptop and the message says can't find the hard drive. I don't have the password for hardware so can't get in to try and fix it. Any suggestions how to solve this would be appreceiated.


Clearing the CMOS (BIOS setting storage) will clear the password.
Go to the Dell website and look for directions on how to clear the CMOS,
or just removing the button cell batter for a few minutes, with the computer unplugged, should also clear it.

6U214 Motherboard Failure??


1. try clearing your bios setup using the jumper provided on your motherboard. make sure that the computer is shutdown and power cable unplugged before doing this. make the jumper settings and wait for 3 to 5 minutes before returning the jumper settings back to its normal position.to locate the bios clear jumper; it's always near the cmos battery of the mainboard. after doing so, plug back your power cable and power "on" your computer. select bios or cmos default settings when you are prompted. save your settings and restart your computer.

or

2. or try flashing your motherboard again using the latest bios file available for your board downloaded from dell website. and select to bios or cmos default settings when you are prompted. save your settings and restart your computer.
