If you happen to lost windows os password, you could go into safe mode (F8 when booting up) to retrieve windows password when you did not remember user account password, but if you forgot administrator passwords, there is no way to change it, you need to use a software program to recover administrator password. Yesterday evening, I forgot my Windows admin password. Last, I successfully recover my Windows password by using Windows Password Seeker. It's worth trying.

What is system password


Hi
I presume that you are referring to the computer system password that is required before you even get to the Windows start up screen.
In this case it is easier for you to download the manual by going here:
Product Support Dell US
and clicking on the "PDF" link beside the Service Manual. You might find it handy to save the manual to your computer for future reference.
There are two sets of jumpers on the motherboard relating to your problem, they are the Password jumper "PSWD" and the RTC reset jumper "RTCRST". They can both be located on the diagram of the motherboard on page 75. The RTCRST is near the battery, and the PSWD is near the Speaker and CPU fan connector.
The PSWD jumper should be set on pins 2 & 3 to disable password features. (See page 90)
The RTCRST jumper should be transferred from pins 2 & 3,and put on pins 1 & 2. After about 5-10 secs this should be replaced on pins 2 & 3. (see page 85)
Hope this is helpful, if so would you please register that with Fixya
Cheers

I have a dell 3000 dimension desk top computer. The message I get after tapping the F12 key is as follows. Key board failure. Type password and press enter to leave password security enabled next line


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.

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.

Were do the jumpers go on a optiplex 330


There is the Password jumper (PSWD), and the CMOS jumper.

The CMOS battery is also termed the RTC battery.
Real Time Clock battery.
The CMOS jumper is labeled as RTCRST.

Real Time Clock ReSeT.

Jumper pin location is confusing if you go with Dell documentation.

http://support.dell.com/support/edocs/systems/op330/en/ug/mtparts.htm#wp1607303


Dell Support documentation shows the RTCRST jumper pins near the Intel chipset, and PSWD jumper pins near the outside edge of the motherboard.

I'm also looking at the Dell Optiplex 330, Technical Guidebook, Inside the Optiplex 330,

http://www.dell.com/downloads/global/products/optix/en/optix_330_techspecs.pdf

Location of RTCRST jumper pins, is near the left corner of the Intel chipset, instead of the right as shown above, and PSWD jumper pins are in the same location.

And several views of Optiplex 330 motherboard's on Ebay,

http://www.ebay.com/itm/Dell-Optiplex-330-Motherboard-Socket-775-KP561-/140870576837?pt=Motherboards&hash=item20cc8a6ac5

(Nice to have that Zoom in feature on Ebay now)

Jumper pins close to the white SATA 2 connector, are the RTCRST jumper pins.

Jumper pins at the bottom side of the Intel chipset are the PSWD jumper pins.

Jumper cap stays on PSWD jumper pins.
No jumper cap on the RTCRST jumper pins.

BIOS PASSWORD RESET


Hi
You need to open up your computer to access inside.
By this process,please be warned of potential ESD [Electro Static Discharge].
On the computer motherboard locate the BIOS clear/Password jumper or Dipswitch and change its position.Its mostly located on the edges of the motherboard,by the CMOS battery or even by the processor.
Its usually labelled,CLEAR,CLEAR CMOS,JCMOS1,CLR,CLRPWD,PASSWD,PASSWORD,PSWD or PWD.
Its currently fixed on two pins i.e.pin 1 & 2 a third pin is not covered.
Now remove it and fix it on pins 2 & 3 leaving pin 1 uncovered.
Turn on the computer let it load and the password is cleared.
Turn it off.Re-fix the Jumper to its original position i.e.on pin 1 & 2.
Turn your machine on now.
Solved?
Remove the CMOS battery [a round 3v Lithium battery on the motherboard] for like 15 minutes.This makes the system to loose all CMOS settings including the password.

Hope this helps.Thanks!
Ken.

Cannot access system -- forgot password. Cannot


Open the computer case. On the motherboard, (looking from the bottom of the motherboard), in the bottom right quadrant, to the right of the CMOS battery, you'll see two jumpers labeled CLR_CMOS and PSWD. You'll want to move the jumper for the PSWD block to pins 2-3 for 5 seconds and then replace the jumper on pins 1-2. This will clear the CMOS password.
