Need cmos jumper location on Dell Dimension 8200 to bypass bios password

The motherboard BIOS is activated when you press the F12 Key and can be locked via a password that is different from your pc user account. There is only one way to reset this because the BIOS is a chip on the motherboard. You have to reset the password using a jumper on the motherboard that is marked with PSWD. This will also clear the CMOS which is Computer Memory on Startup which tells the computer the different changes from the original bios chip. so you may have to go in and set some settings in the bios to have everything back to operational.

Turn off and unplug the tower before opening it.

The password jumper's location on a Dell Dimension motherboard can be found by reviewing the Dimension User Guides.
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.

Now replace the panel and plug unit back in. You should be able to enter the bios without a password.

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.

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 :-)

Hi,
If you can't locate the CMOS jumper another way of resetting your BIOS settings and/or passwords will be to remove the system battery for a few minutes, then replace it.
Best wishes,

I believe that you need to set up the CMOS jumpers inside the main circuit board. For details click on this link (Click Me)
1. Look for 3 pin CMOS clip that says CLR CMOS on the mainboard 2. Take out the jumpers from 1 and 2 3. Put it in jumpers 2 and 3 and wait for 5 seconds 4. Put it back to jumpers 1 and 2

Thank you for choosing Fixya

You can reset bios password with 2 method.
(1) open cpu cabinet cover then find motherboard .Pull cmos cell from motherboard for 15 minutes then again put it in it's position .then it not ask for password.
(2)You can clear password with jumper settings find jumper on motherboard named clear cmos it has 3 pin .1-2-3
Put jumper in 2-3 position then again put it in 1-2 position then check .
Let me know if you need more assistance.
Thanks for using FixYa.

go to dell website and put in yout model number and serial number they will help you unlock it for free in most cases unless its been stolen

Question: How to clear an unknown BIOS password.
Answer: If you have mistakenly forgot or lost your BIOS password or you receive a password at boot that you do not know, you will need to clear the BIOS password by one of the below methods.
Precaution: When inside the computer please be sure of the potential of ESD.

• Try using generic BIOS passwords. A complete listing of these passwords can be found on document CH000451.
• There are utilities designed to help bypass BIOS passwords. An example of a great utility to decrypt / bypass BIOS passwords is the PC BIOS Security and Maintenance toolkit, which is available by clicking here.
• On the computer motherboard locate the BIOS clear / password jumper or dipswitch and change its position. Once this jumper has been changed, turn on the computer and the password should be cleared. Once cleared, turn the computer off and return the jumper or dipswitch to its original position.

The location of the jumpers or dipswitches may vary; however, here are general locations where these jumpers / dipswitch may be located.

1. On the edge of the motherboard - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard.
2. By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual CMOS battery.
3. By the processor - Some manufactures will place the jumpers by the processor of the computer. However, note that in some cases these jumpers will be to change the processor and not the password.
4. Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.
5. Other visible location - While it is possible that the jumpers / dipswitches may not be in a visible location, most manufactures try to make things easier by placing the jumpers / dipswitches in another visible location.

Additionally, when looking for the jumper / dipswitch the label of that switch can be anything; however, in most cases will be labeled CLEAR - CLEAR CMOS - JCMOS1 - CLR - CLRPWD - PASSWD - PASSWORD - PWD.

• On the computer motherboard locate and remove the CMOS battery for at least 10 minutes allowing the computer to lose its information. Note: this will not work on all computers.
• If your manufacturer has a bypass password this can be entered and allow you access to the BIOS and/or computer. Because of the security risk of a bypass password, generally only older computers will have this option. In addition, it is likely that this information will only be able to be obtained from the computer, motherboard or BIOS manufacturer.
• On the computer motherboard locate the CMOS solder beads and jump the solder beads to clear the password. The identification and location of these solder beads can vary and if not available in computer documentation is generally only obtainable through the computer manufacturer.

If one of the above solutions do not clear the password or you are unable to locate the jumpers or solder beads, it is recommended you contact the computer manufacturer or motherboard manufacturer for the steps on clearing the computer password.

A. 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.

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 before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Dell Inspiron BIOS password reset with tutorial help: http://lnkd.in/WN_HMz

Generally, all you need to do is get on to Dell Support and get in a chat with one of their people and tell them that you are locked out by a BIOS password, and needed to get around it. After they verify that you are the owner of the laptop, they should give you a password that gets you through it.
