    Normally on a motherboard, if you are looking at it with all the external connections on your left, then in the upper left corner there should be a jumper that will control the video output. At least that is what I have seen on several motherboards.
    What make is this computer? Might make it easier to find a picture of it online.

How do I remove administrator password on the BIOS of Optiplex 390


The CMOS contains the current BIOS settings
  1. Turn off the computer and disconnect the power cable from the electrical outlet.
  2. Remove the computer cover.
  3. Locate the 2-pin password connector (PSWD) on the system board.
  4. Remove the 2-pin jumper plug.
  5. Locate the 2-pin CMOS jumper (RTCRST) on the system board.
  6. Move the 2-pin jumper plug from the password jumper to pins into the CMOS jumper.
  7. Plug in AC power to the system and wait ten seconds for the CMOS to clear.
  8. Move the 2-pin jumper plug back to the password jumper.
  9. Replace the computer cover.
  10. Connect your computer and devices to electrical outlets, and turn them on.
Location of the RTCRST Jumper will vary by platform and form factor. For more information about the jumper locations refer to the system service manuals located at www.dell.com/support/manuals

How to Test the Relay Board on Stairmaster SM916 Stepmill


How to Test the Relay Board on a Stairmaster SM916 Stepmill Disconnect power from the machine.
Disconnect the main cable from the relay board J1 terminal. Main cable should remain disconnected for the duration of the relay board tests.
With the Power ON, place a jumper wire across the GND/BLK and RLY/RED test points. (Ensure jumper wire only makes contact with the designated test points.)
  • Verify that the Relay LED is lit. Remove jumper wire.
With the Power ON, place jumper wire across the +/WHT and FLD/BRN test points. (Ensure jumper wire only makes contact with the designated test points.)
  • Verify that the Field LED is lit. Remove jumper wire.
With the Power ON, place jumper wire across the +/WHT and with the other end touch the ALT/C, FLD/NC, and RES/NO.
  • Verify that the Field LED lights.
If any of these jumps fail, replace the relay board and or power supply.

Asus 401a rev.2.0 bios password reset


You will probably need to 'default' the mainboard. There should be a 'jumper' (set of 3 pins with a small cap spanning two of them) may say CLR or similar in silkscreen on the board next to the jumpers. Definitely get a manual for your computer to help you find this jumper - hopefully it will be as simple as moving the cap to the third pin (move from pins 1 and 2 to pins 2 and 3) This will short the CMOS and clear it. If everything else is default settings - then you are good to go. Move the jumper back to original position and try to start.

Following are the various ways to clear the CMOS or NVRAM on Optiplex systems:-

The computer must be disconnected from the electrical outlet to clear the CMOS setting.
Remove the computer cover.
Locate the CMOS battery on the system board.
Note the orientation of the battery, usually the plus side is up, and remove it.
Wait for 3 to 5 minutes for the CMOS to clear.
Replace the battery in the socket.
Replace the computer cover.
Plug the system and devices back into the electrical outlets and turn them on.
And Sec option jumper setting also available you can used:-
Turn off the computer and disconnect the power cable from the electrical outlet.
Remove the computer cover.
Locate the 3-pin CMOS jumper (RTCRST) 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.
Close the computer cover.

I want to break my bios password.


if you are using a desktop computer you can reset *********** board settings by removing the battery or by connecting the jumper setting but to do this you need the manual of the mother board. you need to find the exact place where to connect the jumper. if you are using the laptop there is no way you can reset the motherboard of the laptop. some people use a program just to reset the bios settings but for it is quite dangerous. because it might damage the bios program in the mother board.

How can i disable chassis intrusion on p5kpl-am se board? the board don't have any intrusion switch...


For the chassis intrusion circuit to work, the chassis power supply must be connected to AC power. By default, on the motherboard the pin labeled chassis "signal" and "ground" are shorted with a jumper cap. You need to remove the jumper caps if you intend to use the chassis intrusion
hope this helps

Chassis intruded asus m3a78-cm


I actually did a little research on this one. I downloaded the User Manual for this board. USUALLY, there is a jumper on the board somewhere that needs to be set in the correct position. I looked through the manual and can't find a jumper for this . I even looked through the bios setting just in case it might be covered there, no luck. If you can't find an undocumented jumper on the board somewhere labeled something like TRPWR, then I would try the reset next. My suggestion would be to use the LCRTC jumper to reset the board. Heres the procedure according to page 1-17 of your manual:

Clear RTC RAM (CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords.
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5-10 seconds, then move the cap back to pins 1-2.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and enter BIOS setup to reenter data.

Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default position. Removing the cap will cause system boot failure!If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After clearing the CMDS, reinstall the battery.

You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the CPU Parameter Recall (C.P.R) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values.

Basically your bios need resetting or clearing there are 2 ways, you can use your main board manual to locate the jumper as descrobed below or if you cant find it or that fails then proceeed to the other method described.

.) Find the Jcmos or Jp1 or JBAT jumper located on the board. Its a 3 pin jumper currently set to 1 and 2,,, set it to 2 and 4 wait a few then set it back to 1 and 2.

If you cant find the jumper or that fails then


  1. Locate the battery on the main board
  2. unplug the system then remove the battery and the memory(rams)
  3. press and hold the power button for 3 seconds
  4. release
  5. replace the battery then the memory (rams)
  6. pulg in the system and turn it on, it should boot
  7. load the optimised defaults by entering setup , follow the on screen instructions to do this
  8. thats it your done

Password for 486


Remove the battery from the mother board.
Jumper the CMOS to discharge it. You may
want to check you Mother Board manual, to
see which jumper it is. Some require you to
turn the Mother Board BACK ON for two seconds. (It will NOT come up, just will
discharge the CMOS and the battery will NOT
be there to replace the energy, so everything
is GONE. You will know if you have done it right, when
you boot up again, the BIOS will NOT recognize the hard disk (need to set it up
again), the date will be wrong (set it up again also) and the floppy drive will not
be recognized (new setup). But then try your password. It should let
you right in then. Let me know if it works. Best Regards, PS Make sure you have the right mother
board jumpers to discharge the CMOS, YOU
CAN DO DAMAGE ALSO, if they are not the
right ones.
