Im presuming we are talking about the Supervisor Password. (Screen boots to a lock symbol) If so im afraid that there is not a reset jumper as the password is stored on a chip.

To read the chip to get the password would require major 'surgery' on the laptop.

Im not aware of any other soloution to this issue.

Bios password


On the computer motherboard locate the BIOS clear / password jumper or dipswitch and change its position. This jumper is often labeled CLEAR, CLEAR CMOS, JCMOS1, CLR, CLRPWD, PASSWD, PASSWORD, PSWD or PWD. To change the jumper remove it from the two pins its currently on so that it covers the pin that is not covered. For example, in the picture to the right pins 1 and 2 are covered, you'd remove the jumper and put it on pins 2 and 3.

Once this jumper has been changed, turn on the computer and the password should be cleared. Once cleared, turn the computer off and return the jumper or dipswitch to its original position.

The location of the jumpers or dipswitches are dependent on the manufacturer of the computer and motherboard. However, below are some general ideas on where to find it. Remember that most motherboards could have dozens of different jumpers, make sure you're changing the CMOS jumper and not something else. If these general suggestions do not help refer to your motherboard / computer documentation or skip to the next step.

  1. 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.
  2. By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual CMOS battery.
  3. By the processor - Some manufactures will place the jumpers by the processor of the computer.
  4. 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.
  5. 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.

Hi! How to remove bios password from Toshiba Satellite A500?


I got a bios protected Toshiba A500 PSAR9A from auction. Solved by the method below:
1. Open ram cover and remove all rams
2. Tear off the sticker on motherboard.
3. you will find 2 jumpers there, J2 and JCOMS.
4. Use some kinds of metal wires to short connect JCOMS, use some tape to stick it, make sure the metal wire under the tape is exactly short the jumper.
5. Put the ram back and turn on the laptop
6. The ps should be removed, then take the metal wire off.
Don't know if all steps needed because have no chance to try again. But this method is exactly works.

The location of the jumpers or dipswitches may vary; however, here are some locations of the jumpers / dipswitches.

  2. By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual CMOS battery.

  5. 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.
  6. Jumpers may also be found underneath or allongside the memory modules.
I hope this helps but suggest that the manufacturers web site or your instruction manual, may have the answer.

Bios password problem on a hannstar j mv4 94v


you will need to get to the jumpers for bios to be able to reset the password or remove the password, this is easy with a desktop computer, but if you have a laptop but you think you guys can open the laptop and locate the bios or cmos jumpers then go ahead.

Can anyone help me on how to reset the Bios password to default on an HP Compaq 6710b Laptop? I have an HP Compaq 6710b Laptop. It is booting but it cant go beyond bios boot and i cant enter setup as it is...


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

Forgot BIOS password


Question: How to clear an unknown BIOS password.
Answer: If you have mistakenly forgot or lost your BIOS password or you receive a password at boot that you do not know, you will need to clear the BIOS password by one of the below methods.
Precaution: When inside the computer please be sure of the potential of ESD.
  • Try using generic BIOS passwords. A complete listing of these passwords can be found on document CH000451.
  • There are utilities designed to help bypass BIOS passwords. An example of a great utility to decrypt / bypass BIOS passwords is the PC BIOS Security and Maintenance toolkit, which is available by clicking here.
  • On the computer motherboard locate the BIOS clear / password jumper or dipswitch and change its position. Once this jumper has been changed, turn on the computer and the password should be cleared. Once cleared, turn the computer off and return the jumper or dipswitch to its original position.

Additionally, when looking for the jumper / dipswitch the label of that switch can be anything; however, in most cases will be labeled CLEAR - CLEAR CMOS - JCMOS1 - CLR - CLRPWD - PASSWD - PASSWORD - PWD.
  • On the computer motherboard locate and remove the CMOS battery for at least 10 minutes allowing the computer to lose its information. Note: this will not work on all computers.
  • If your manufacturer has a bypass password this can be entered and allow you access to the BIOS and/or computer. Because of the security risk of a bypass password, generally only older computers will have this option. In addition, it is likely that this information will only be able to be obtained from the computer, motherboard or BIOS manufacturer.
  • On the computer motherboard locate the CMOS solder beads and jump the solder beads to clear the password. The identification and location of these solder beads can vary and if not available in computer documentation is generally only obtainable through the computer manufacturer.
If one of the above solutions do not clear the password or you are unable to locate the jumpers or solder beads, it is recommended you contact the computer manufacturer or motherboard manufacturer for the steps on clearing the computer password.
