How can I reset the password ona dell precision 360? Pulling the CMOS battery didn't work and moving the jumper didn't work.What can I do ?

Have you tried resetting the password by moving the jumper on the motherboard?

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.

Good luck

The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing a battery for 30 minutes from the motherboard.

Another way is to reset the clear CMOS jumper on the motherboard itself.
Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip.
So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased.
Hope this helps

To reset the BIOS read the information from this link.

In case of your laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

you can try pulling the motherboard battery for 10 min.(unplug the unit first) also on your board should be a jumper to clear it. it can be labled as clear CMOS or PW or PASS or any variation. most of the time this works. if it is a BIOS bassword this probably wont work and you will have to contact Dell. you will have to show proof of ownership and jump through hoops.

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.

For that you need to reset bios password.
There is 2 way (1) Reset bios password with cmos cell and jumper settings.For that you need to open back cover of laptop then find motherboard pull cmos cell from motherboard for 10 minutes then reattach it into it's position.There jumper near cmos cell named clear_cmos it has 3 pins 1-2-3 put jumper in 2-3 position then power up then again put it into it;s original position 1-2 then all password RESET.
(2) you can RESET bios password with software download it from below link.

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

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.
