Many motherboards have a "clear CMOS jumper" capability. There are 3 pins on the Mobo and the jumper is put on pins 1 - 2 for normal operation and moved to position 2 - 3 to clear CMOS memory. (It may be the other way around on some Mobo's). Your PC will oly work with the jumper in the normal position. If you temoraily moved it to the clear position (and then put it back to normal) you erased your cmos memory which remembers the date & time, hard drive cofiguration and many other importnt parameters which need to be set correctly in order for your PC to run properly. If you have the manual that came with your motherboard, it explains how to go into cmos setup and set these parameters. If you do not have this manul, navigate through the menus and choose "default (or optimal) bios settings" Then set your date and time, choose save bios settings and exit bios setup. Hopefuly your computer will start up OK now. If not, you should find a PC technician to help you.

How to reset or remove BIOS password


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.<br /> <br /><b>Manufacturer Backdoor BIOS Password</b><br /><br />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. <br /><br /><b>Reset the jumper that holds the password<br /></b><br />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.<br /><br /><b>Removing the CMOS Battery to reset the BIOS to default</b><br /><br />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. <br /><br /><b>Using third party software utility to reset BIOS password</b><br /><br />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 <a href="http://www.hirensbootcd.org/">http://www.hirensbootcd.org/</a>.

I have dell CPX H500GT and lost BIOS password


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


The most common way that most of us 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 a 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 the battery power, the BIOS/CMOS settings will be erased.

cmos battery 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.

hope this helps

Need to change mouse settings on bios but i forgot my password


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.

Powers up no video and mouse stays lit when powers off


This is an old motherboard, with this in mind there are a couple things for you to try. Power off the system and unplug the power cable from the power supply. Remove the left side of you're case. Touch any metal surface to discharge possible static.
First clear the cmos jumper on the motherboard. See page 1-17 in you're manual for the location of the cmos battery and cmos jumper. Also see page 1-21 to clear / reset the cmos battery. (Don't forget to set the jumper back to normal after 30 seconds.
Doing this will reset the bios to its default setting.
If you added a graphics card to one of the PCI slots remove it.
(For now).
Re-connect the power cord for the power supply and power-on the system. If the motherboards built in VGA controller is working you should have display on your monitor and since we cleared the cmos the bios will want you to enter the bios to adjust all its settings.
If you do not have display than the onboard controller is defective. You can add a PCI video card into any one of the 3 (White in color PCI slots). It’s not uncommon for the mouse to stay lit. If you're mouse is plugged into a PS-2 port try un-plugging it when the system is off.
Then re-connect it with the system off. You can also buy a USB to PS-2 adapter. Most new mice and keyboards come with this type of adapter. See the link provided; http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=776087&CatId=469
If you're mouse and keyboard are PS-2 and connects to the system by USB, try another opened USB port. The next link opends to Biostar and you're motherboard;

845gvsr startup problem


Try changing the CMOS Battery, Are you sure you are putting the jumper on the right pins, what happens if you save and exit bios without changing the jumper back, you may be resetting the CMOS with the jumper. does the clock keep accurate time if you leave the jumper on so you can get into the BIOS after turning PC off unplugging power then plug back in and check time in BIOS, if it is not keeping time, you may have a bad battery

Acer 8000 desktop. Cleared password moving the jumper pin. Put the jumper pin back turned back on and it will not post to boot. Lights on the keyboard keep blinking and no post to boot.


It is possible that your video settings in the BIOS has been reset. When you move the jumper pin to reset, the BIOS automatically resets to defaults. Depending if you are using a PCI card for video or the integrated graphics card AGP on the motherboard. You need to set this correctly otherwise you will not see anything. Worst case scenario, remove the CMOS battery for ten minutes and when you turn on the computer try to activate setup. go to the advance options and see if you are using the correct settings. I hope this helps.

No response from Monitor, Mouse and Keyboard


Definitely a "faulty" motherboard. If fans on PC do not turn, no lights come on and dead screen.

If lights come on, and fans turn, try to reset the BIOS by removing your CMOS (and setting the jumper to clear for about 5 minutes, then put the jumper to normal again) battery for 5 minutes.

Sometimes the bios just "stuffs" up and you'll get no response from your pc at all. So all you do is "CLEAR THE CMOS/BIOS"
