These jumpers are almost always located close to the CMOS battery or close the PSU power connector. If you open the unit up and remove the drives to see the board, it'll be either green or blue and it'll say PSWD right beside it. Remove it, power on wait for the Password Clear message....done.

SOURCE: locate the jumper for the cmos

Check the manufacturers website for jumper location... Alternatively, if you can get a good look at the motherboard, sometimes the jumper sequence and location is stamped on it

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.

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


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.

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.

How do I reset my lost bios password for Dell Precision M70


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.
