need hdd master password


When you boot up to the log in screen type in administrator as user to log in if you cant log in

during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up press and hold that key during the boot up process to enter BIOS scroll down to set user password or supervisor password you can change or remove your password from there

also

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 the Cmos 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

Hi,

There are four common categories of solutions to remove or reset a BIOS password and here are the details on how to go about resetting your BIOS password.

Manufacturer Backdoor BIOS Password

Most of the BIOS makers have set a backdoor password on the older computer models. That is the master password for BIOS. To reset BIOS passwords first you need to check the manufacturer of your computer's BIOS. Most computers have BIOS include AMI,
IBM, Award, and Phoenix. These are the most common BIOS. You can unlock your locked BIOS using this master password. It works, no matter what the user sets the password to. Many popular computer and laptop manufacturers such as HP and DELL lock the BIOS because they want to protect their machine's most sensitive areas (those areas which have warranty) from their customers. These passwords are usually used by computer technicians for testing and repairing.

Reset the jumper that holds the password

Open the computer and locate on the motherboard the BIOS password jumper. The jumper is usually jumper 1 and often labeled as PSWD, PWD, CLRPWD, CLEAR, JCMOS1, CLR, CLEAR CMOS, PASSWD, or PASSWORD. Normally you would have 3 pins and to reset the password you just need to put the jumper on the 2 and 3 pins leaving pin 1 empty. After you move the jumper, turn the computer on to clear the password, then once password removed turn it off and put the jumper back to its original position.

Removing the CMOS Battery to reset the BIOS to default

Switch off your computer, and open up the case. You'll see a circular metallic silver item on motherboard. This is called CMOS Battery. Remove it carefully, and leave it out for about 2 minutes. This act will remove the CMOS memory which contains BIOS password. Set the CMOS battery back and switch on the computer. Restore the CMOS configuration as default. Your BIOS password has been cleared now.

Using third party software utility to reset BIOS password

To reset BIOS you can use third party software like Kill CMOS which wipes out CMOS, or CmosPwd which is a BIOS utility. Hiren's Boot CD has a few programs including the above two that will help you to reset the password. Here is a link to Hirens Boot CD website http://www.hirensbootcd.org/. To download the latest version, click on the Download link on the left side and go to the last page. You will need a CD writer to put the content on a blank CD.

Please let me know whether this works or not.

My Dell XPS 400 PC will not Boot up past the "System password"


Both the system password and the BIOS password are set in the BIOS CMOS. You need to clear the CMOS.

The online Dell service manual for the XPS 400 provides a clear and detailed procedure for clearing the CMOS. It's just a matter of moving some jumpers around:

If you are not used to working inside computers, start with "Removing the computer cover", then go to "System Setup" and click on "Clearing Forgotten Passwords".

Another method is to unplug the power cord and remove the CMOS battery for a 1/2 hour or so. For details on how to do that, try this website:

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
