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.

I can't find the jumper on my dell inspiron b130


Hi,what type of jumpers do you mean? if you want to clear your bios you can use jumpers calls "CLR-MOS" or "CL-ms" or "cms_clr" that it means CLEAR CMOS or CLEAR MOS (stands for mosfet transistors built in mother board eeprom" you can clear it this way:
shutdown the pc or laptop find the jumper pull the backup battery up use a screw driver or an iron pin to short the jumpers together(if you dont find the jumpers after pulling up the battery short the battery+- together) wait 10 sec and then pull in the battery after that you have to go to your bios setting and set some data if you dont you may see errors like this in your screen before windows start up:
"DMI POOL DATA CHANGED" PRESS F1 TO continue" or something like that;
and if you dont know the bios setting ask from experts to do it for you because this setting is too dangerous and may harm your hardware,if you dont know dont touch it,
and one more thing:
if you mean another jumpers?dont touch it because some mother boards use jumpers for their settings or you may harm your hardware
kind regards

You probably need to clear the BIOS password. If you can find the correct jumper, you can do it that way. If not, unplug the computer, then carefully remove the battery from the mother board and leave it off for a half hour or so to make sure all capacitors have dissipated. Replace the battery and you should be good to go.

Can' get back on computer


Hi. Is it the bios password or Windows password? If it's the bios jumper 1 on the mother board is the bios reset. Just reset the jumper and all shoul be good. If its windows it may be an administrator password you had when you set up your pc that being the case, depending on how you setup windows you may be able to press ctrl,alt, delete to get to user menu and press enter, alternativly clear the box and press enter.

Sony vaio VGN FJ290P password reset sony vaio VGN FJ290P


I have set the password for administrator when i entered the bios set up. you can change its setting but not the configuration unless you've entered the password. you can't change the password with a new one if you cant enter the old password. Next time dont forget your password because laptops has its security even when stolen you cant open its bios set up if its protected by password. CMOS battery is in the mother board. You need a service technician to open your laptop to reset the bios setup battery.
