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

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.

Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it.

I have a dell 3000 dimension desk top computer. The message I get after tapping the F12 key is as follows. Key board failure. Type password and press enter to leave password security enabled next line


The motherboard BIOS is activated when you press the F12 Key and can be locked via a password that is different from your pc user account. There is only one way to reset this because the BIOS is a chip on the motherboard. You have to reset the password using a jumper on the motherboard that is marked with PSWD. This will also clear the CMOS which is Computer Memory on Startup which tells the computer the different changes from the original bios chip. so you may have to go in and set some settings in the bios to have everything back to operational.

Turn off and unplug the tower before opening it.

The password jumper's location on a Dell Dimension motherboard can be found by reviewing the Dimension User Guides.
For most Dell Dimension desktops, the steps to reset a BIOS password and clear all CMOS settings are:
  • Locate the 3-pin CMOS password reset jumper on the system board.
  • Remove the jumper plug from pins 1 and 2.
  • Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
  • Replace the jumper plug on pins 1 and 2.
Now replace the panel and plug unit back in. You should be able to enter the bios without a password.

Is asking for password when coms on forgot it


There is usually a jumper on the motherboard that you can remove to clear BIOS settings including password if the password is a request of the BIOS. If it is a Windows or other operating system that is asking for password you are probably going to have to reload operating system. Look on motherboard for small jumper with the word BIOS imprinted next to it. Make sure power is off, remove jumper and restart pc. When BIOS comes up do not set password protection. Shut pc down, replace jumper and your bios settings should be fine. Good luck

I forgot my bios password, i want to reset my bios password


A. By Removing the CMOS Battery:

cmos_battery.jpg Almost all motherboards use a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for approx. 15-30 minutes and then put it back. It'll reset all BIOS settings as well as the password and you'll need to re-enter all settings.
If it fails, then try to remove the battery for at least one hour.
B. By Using the Motherboard Jumper:
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.

I just asked about removein the startup password wat do mean with the jumper i am new with computers so could u explain a lil more


3ac542afbc4ff40fe47b72448dec8cca.png they look like this and can be any color... Most motherboards can have the BIOS password reset by moving the jumper to the correct pin position. Many motherboards have small print by the jumper to indicate the correct positions. For example you might see some pins on the mother board, with a jumper like the one above, with the words PSWD RST or something similar wrote on the mother board. If the jumper is on pins 1 and 2 move it over to pins 2 and 3, then reboot your computer. Then shut down the computer down and put the jumper back where it was and it should have reset the pass word.

I would advise you to compare my instructions to that of *********** boards manual which you can download form the mother boards manufacturers website.

How to remove a bios password


You need to reset your BIOS using either a jumper (not usually well documented on laptops) or otherwise remove the CMOS battery (large watch battery looking thing) on the motherboard of the laptop for at least a few hours. If you know the model name and or number of your laptop I may be able to help you find documentation on how to do this.

Where is Cmos Clear jumper on motherboard to clear Bios password.


If you can't find the jumper, just remove the CMOS battery wait for 1/2 + hour and the re-insert the battery. This will reset the BIOS back to the default settings and you then need to set the Time & Date.
It may not remove the BIOS password if the laptop stores the password on an EEPROM chip.

I have a duel core pc system but need to get rid of the bios password to gain access, can anyone help?


Find a diagram of your specific motherboard. Find the jumpers for clearing your bios. There will be a setting that will reset all bios options to default... Make sure you are tampering with the correct jumpers. Playing around with the wrong ones can do serious damage to your motherboard. However, the manufacturers site should have thorough instructions on how to set them. Clear the bios/resetting to defaults should clear any passwords.
