Can't reset password, disabled at jumpers still have old password

This is both trickier and easier than you might think.

1. Shut down PC, disconnect power, and open case.
2. Look for two pins sticking up off the motherboard that say: "RESET CMOS" or "CMOS PASS" or "BIOS PASS" or "BIOS RESET" or some combination.
3. There should be a plastic "jumper" that is attached to ONE of the pins on the CMOS jumper (step two).
4. Carefully remove the "jumper" by pulling straight up on it.
5. Replace the jumper so that both pins are inserted into it.
6. Connect Power and Power On your PC
7. (it may beep loudly and shut off or it may startup like normal, allowing you to get into your BIOS)
8. Shut down PC, remove power
9. return the "jumper" (step two) so that only one pin is connected like you found it.
10. Power on your PC and you should be good to go.

NOTE: If you don't have a jumper on your motherboard, you will need to find one. Often, a CD-ROM drive or old IDE hard drive will have a jumper on it. If you find a jumper on an old device that is not connected and not running, you can use it so long as you remember to return it to it's original position. Failing to return a "borrowed" jumper from an external device could make it unusable in the future.

Also, never use a jumper from elsewhere on your motherboard. These jumpers can be critical to the operation of your PC and "borrowing" one could render your PC useless and may not ever help you to reset the BIOS password.

NOTE: When you reset the BIOS password in this manner, all of your custom BIOS settings will be reset. Any hardware that you had to configure manually through your BIOS may not work. Overclocking and other features may be disabled by default. This should not be done without proper consideration.

Hope this helps,

Disabling a Forgotten Password

If you forget the system password, you will be unable to operate the system until disabling the password. Disabling the password involves going inside the computer and changing a jumper setting (twice) on the system board.
To disable a forgotten password, perform the following steps:

1. Turn off the system and remove the cover.
2. Move the jumper plug on jumper A to pins 2 and 3 to disable the password(s).
3. Turn on the computer. Powering up the system with jumper A set to the disabled position erases existing password(s). Before assigning a new system password, you must reset jumper A to the enabled position.
4. Turn off the computer.
5. Place a jumper plug on pins 1 and 2 of jumper A to enable the password features.
6. Replace the computer cover.

The BIOS password can be reset by lifting the (usually white) plastic jumper on the logic board. It will be on two pins and should be the only jumper on the board itself. I can't be certain where it is on your board, as the boards are always so different.

Not tried it and can't guarantee how good it is. But what have you got to loose?

Hi,

If you short the CMOS jumper on the motherboard , you can reset the setup password . Find the CMOS jumper near to the CMOS battery . If you can't find the jumper , just remove the CMOS battery and smps power cord . Wait 3 min and re insert the battery . Now check it will not ask setup password .

Thanks

The BIOS password is a hefty security measure, and consequently, is difficult and in some cases impossible to disable if you do not already know the password that was set. Dell offers a recovery service if you can prove purchase. Acer does not provide any kind of easy solution, but most use a BIOS developed by Phoenix, and you might (and thats a big might) be able to recover the BIOS (a.k.a. wipe the original, which requires a password, and replace it with a 'fresh' one). If you are interested in this endeavor, I came across a handy tutorial if you want to try it out. http://forum.notebookreview.com/sager-clevo/326954-case-you-kill-your-phoenix-bios-bios-recovery-methods.html

if you are just wanting to disable the password function on the machine here is the steps to do that:
1.turn the machine off
2. hold the 2 and 5 while you turn the machine on
3.press the p button then 0 5 then press the p button
4.press 0 then start
5 turn the machine off then on
this disables ecm function so you wont have to enter a password to make a copy

The following information was found here http://www.darklab.rutgers.edu/MERCURY/t15/pe2850dell.html

This should take care of your issue.


Password Jumper Place the jumper on both pins to enable the password. To disable the password, remove the password jumper.

have you tryed going into the bios and reseting it , some times you can reset this in the bios

thanks
hope this works for you

As another option you could try resetting the jumper. Some boards save the password regardless unless the reset the BIOS by using the resetting jumper. Refer to the motherboard's manual for further information on how to do this.
