Sounds like the possibility of the power supply has failed. have you tried or do you have access to another power supply to see if the computer will turn on with another power supply?

How to install a power supply


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Unplug all electronic cords connected to the computer. At no time during the installation should any cords be connected to the computer. Remove the screws holding the computer cover case, and remove the cover case. Locate the computer power supply box, which looks like a large box out of which a bundle of wires run and connects to the power cord jack on the outside of the computer case. Unplug the power cables from the internal devices connected to it. Be careful not to damage any of the sensitive control boards or devices inside the computer, and be certain to remember--write it down if you need to--what devices will need reconnecting to the new power supply when you finish the installation. Unscrew the power supply from the inside of the computer case and remove it. Check the original power supply's red voltage switch for the correct setting. It should read 120 or 240 if you live within the United States. Confirm this setting as the correct voltage setting for your power outlets. Make sure your new power supply gets set to the correct voltage setting before you install it. If it cannot be set to the correct voltage, do not proceed with the installation or you may damage your computer. Return the new power supply and buy one that is compatible with the voltage requirements. Install the new power supply, reattach the screws that will hold it in the proper place inside the computer. Reattach the power cables that come from the new power supply to the devices that were connected to the old power supply. Make sure all of these connections are firmly in place before you turn the computer back on. Reattach the computer power cables and all the cords connected to the computer during normal operation, but do not close the computer case yet. Keep your hands clear of the inside of the computer case as you attach power cords and peripheral devices. Turn the computer on and observe the performance of the computer without touching anything inside. Do all the computer fans function normally? Does the computer operate as well as or better than before? If you feel that the computer behaves normally and you do not encounter any problems, turn the computer off, remove all the power cords and peripheral cables once more, and close the computer case. Then reattach the power cords and peripheral cables and begin using the computer. Check for errors if you encountered any problems starting the computer or if it would not start at all, unplug all the power cords and computer cables connected to the computer and look inside. Make sure that you connected all the correct power cables inside the computer securely and did not miss any. If you have confirmed this and the computer still doesn't start or operate normally, call your computer manufacturer or a professional computer repair shop for assistance completing the installation http://www.youtube.com/watch?v=xvClS_M-09o&feature=watch_response_rev watch video http://www.youtube.com/watch?v=s0udZ0Ky4Pk Hope this helps.

All cords are correctly put on, when I turn the desktop on, my monitor doesnt power on, its stay off.


I apologize for thinking so simply, however, your monitor has a separate power button and power cord. Therefore, even if you computer is off, there should be power to the monitor unless the monitor is not plugged in or the power button is turned off.

Check the power button and power cord for the monitor.

check your power cord to insure that you are getting power. make sure power cord is plug in the back.
look in back of computer. you will see a little orange switch. it says 115/220 click to 220. boot computer.
if computer boots up turn off and click back over to 115.
if it does not boot your power supply in your computer needs replacement.

Hp compaq nx7400 - battery died and power cord will not turn comp


Do you have another power cord to check? Most places like bestbuy is willing to let you test a universal power cord for your type of laptop before you buy. Usually in your case, the power cord or connector has gone bad. If you test the laptop at the store and it doesnt work then its your connector but if it works. you could consider buying that power cord.
