When you remove the battery from the motherboard wait after few seconds (30), reboot your computer without the battery and press the BIOS key (F1 or F10 or DELL key) will not ask you any password. Turn it off and Then put back the battery.

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.
1. Using another computer, load up your Internet browser. Go to this website, and write down the code shown on the locked computer.
2. Pay the Small fee, and then enter the code you have written down. A few codes will be provided, so try them all until you find the one that works.
This also works for locked HDD drives, so make sure you take a look.
3. You're computer is now unlocked! Keep the backup password handy, this will be invaluable if you locked out of you're pc again.
Method 2 of 3: Reset Jumpers to Clear a CMOS Password
1. Unplug the computer and remove all peripheral connections like monitors and printers.
2. Reduce electrostatic discharge (ESD). Wear a wrist strap to eliminate ESD, or make sure 1 hand is holding a metal piece while you are working inside the computer. Wear rubber soled shoes, and stand on an ESD mat if possible.
3. Open the computer. Locate the CMOS jumper. The jumper will usually consist of 3 pins, though on the rare occasion, 2 pins (requiring you to supply the jumper itself). This often is labeled with "clear," "cmos," "password" or some abbreviation that indicates it is the password jumper. It is usually located near the CMOS battery, or processor. In laptops, it is often a dipswitch at the bottom of the laptop. Consult your motherboard documentation to find the location if you are unsure of where it is located.
4. Make note of which pins the jumper covers. Remove the jumper. Reinstall it so that it covers the pin that is currently not covered. For example, if it covers pins 2 and 3, change it so that it covers pins 1 and 2.
5. Reassemble the computer, and re-connect the power. Turn on the computer. Check to see that the password is cleared.

6. Turn off the computer. Disconnect the power cord, and open it. Change the jumper settings back to the original position.
Method 3 of 3: Other Methods to Clear a BIOS Password

1. Search online for generic CMOS passwords. Older computers sometimes have a generic password set by the manufacturer. To find one, search for the name of your manufacturer. Keep in mind that the computer password may have changed or no longer is in use.

2. Download a utility to bypass the computer password. These can be found online and loaded with a CD or floppy disk.

3. Take out the CMOS battery. Leave it out for longer than 5 minutes, and then reseat it. This will clear all BIOS settings, including the password. Keep in mind that you will have to reset the BIOS date, time and other settings.

4. Contact the manufacturer. Find information about the motherboard, and call either the motherboard or computer manufacturer. They can tell you whether there is a CMOS default password or solder beads that must be jumped.

Hi when you say hdd password.. do you mean the boot password? if this is the case, then you could try unpluggin the pc, pres and hold the power button for about 10 secs, removing the bois battery, then putting everything back together. This will wipe the bios, and the password.
Although the BIOS usually runs without errors, it can become corrupt in rare instances. If you're unable to enter your BIOS, or if you set a system password in the BIOS but forgot it, you might be able to fix the problem by clearing the CMOS memory. On some motherboards, this requires you to turn off and unplug your PC, disconnect the CMOS battery for a few hours, replace the battery, and turn on your PC again. Other motherboards have a CMOS clear jumper pin that you must move to a temporary position and then return it to its original position. Check your motherboard's manual to see which process you'll need to follow.
If a clear jumper pin isn't available and temporarily removing the battery doesn't work, check the motherboard manufacturer's Web site for instructions about resetting the BIOS.
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.
