On the edge of the motherboard - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard. By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual cmos battery. By the processor - Some manufactures will place the jumpers by the processor of the computer. Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment. Other visible location - While it is possible that the jumpers / dipswitches may not be in a visible location, most manufactures try to make things easier by placing the jumpers / dipswitches in another visible location. 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. hope this helps
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.
