Location on moterboard for bios jumper, dell 780

Dell Optiplex 780, user forgot BIOS master password (which is necessary to change the boot order to run BartPE from CD and do an image backup).

There is a jumper on the mainboard called PSWD1, which is set (shorted). Remove power cable from PC (CMOS battery can stay in place), open the lid. Remove jumper from PSWD1. Reconnect power, start the PC, hit F2 to enter BIOS. All passwords should be reset.

Leave BIOS, power off the PC, remove power cable. Reattach jumper to PSWD1, close lid, reattach power cable. Start PC. Enjoy.

From what I can gather, you just need to locate the jumper labeled PSWD and remove it. Turn computer back on, then back off. Replace jumper pin and turn computer back on. That should do it. Removing the jumper disables password. Turning on computer resets it. Replacing jumper re-enables password capability.

Hi!

It so simple, you don't need to blow your mind looking and thinking of the password. Just reset the BIOS jumper configuration straight from your motherboard and the password will be gone.

Open your computer system case and then look for this thing:



Next, move the jumpers from the their default location (Example: from across pins #1 and #2 as above) and then place the jumper across pins #2 and #3.

Leave the jumper in place for 20 to 30 seconds and then return it to its default location.

Its done! The password is gone!

Or you can try also this procedure.

- Just remove the BIOS battery and place it back.


Refer to your motherboard manual to do this as reference.

Have a nice day!

Thank you for reaching us.

To remove the bios password you need to clear the CMOS.
Open your laptop casing look at your motherboard. locate the CMOS jamper it is near the battery. To clear remove the jamper and turn your computer on with in 5 to 10 seconds and turn it off. Reinsert the jamper back to there proper place and try to turn go to BIOS if there will be a password box appear.

You need to open your laptop and look at the motherboard and locate the CMOS battery. Just remove it with in 5 minutes to clear BIOS password.

Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.
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.
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 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

send me the service tag wich u can see on the bottom cover or trun on laptop u will see on screen hash code like this XXXXXXX-595B or D35b or 2A7B send me complete .ill send u password .

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

there's a software that does it but it's not free

Hi,
If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.
On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.
If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.
The BIOS password may be cleared from a Dell Optiplex by removing the password jumper (PSWD) from the motherboard.
The location of the password jumper on a Dell Optiplex motherboard can be found by reviewing the Optiplex User Guides.
For most Dell Optiplex 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.

Each Dell Inspiron has a master password which will clear the BIOS password. You can get this number by calling Dell Technical Support at (800)624-9896.
Dell Technical Support will request the Service Tag and Express Service Code from the bottom of your Inspiron.

Thank You,
Your Support Tech.

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.
