NO LED LIGHTS COME ON WHEN THE POWER BUTTON IS PRESSED

The computer makes no sound and does not power up. The outlet and
power cord have been checked and the CMOS battery has been replaced.
Could it be the power switch or the power unit? Please reply. Thank you.

If there aren't any lights and the fans do not spin up,it is definetly the power supply. Unplug the Ac from the back of the computer.
Then take the power connector from the power supply off of the motherboard. wait 30 secs. then plug it back into the motherboard. Plug the AC back into the PC and power it up. If this does not work then it is the PSU.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

When i turn the computer on theres no picture no sound and pretty sure its not powering anything on


Hi there,
please check if you can see any light or LED display when you press the power button.
If none. Check if the power cable is tight on the back of the computer and check if it's plugged into a power outlet.
You can also try plugging it into a different power outlet just to make sure it's not the Power outlet that has a problem.
You can also try to switch the power cables.
Hope this works, if it doesn't you will have to tear down the parts of the computer to check where the fault is coming from.

If the electrical outlet works, but the product still does not turn on , continue to the next step.
Solution two: Make sure the power supply is compatible with the HP product
The term power supply refers to both the power module and the power cord.
NOTE: To make sure that your product and power supply are compatible, HP suggests you use the original power supply shipped with your product.
Example of a power module Example of a power cord
NOTE: The power module might have a permanently attached power cord, or the power cord might detach from the power module.

Make sure the voltage and amperage specifications printed on the power supply match the voltage and amperage specifications printed on the HP product.
Voltage and amperage specifications printed on the power supply Voltage and amperage requirements printed on the HP product

If the voltage and amperage specifications between the product and the power supply are compatible, make sure the connector on the power cord is the same shape and color as the connector on the HP product.
WARNING: Do not force a power cord into an HP product that is incompatible with the HP product (different shape or size).

If the power cord is not compatible with the product, replace the power cord with a compatible cord. To buy a compatible cord, right-click the following link, How to Buy HP , and then click Open in New Window .

    Fast green blink


    Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:

    1.Disconnect everything from the computer, including the power cord.
    2.With the power cord disconnected , press the power button on the front of the computer for five seconds. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
    NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply

    3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America.
    Performing this step ensures that the voltage switch is engaged and set correctly for your country/region.

    4. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
    5. Plug a lamp into the same outlet to see if the wall outlet has power. Try the computer in a different outlet in order to eliminate the outlet as a possible source of the issue. Test both to see if the wall outlets have power.
    6. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet. Test for power. If this fixes the issue, find the device that is causing the issue and do not use it.
    NOTE: If you find the device that was causing the problem was a surge protector, resetting a breaker or fuse on the surge protector may fix the issue.
    8. Remove all attached devices except for keyboard, mouse, and monitor.
    9. Remove any internal component that was recently added, such as video card, memory, CD, DVD, and hard drives. An added device may take more power than the power supply is rated for. If the problem goes away when the component is removed, the only option is to upgrade the power supply to power supply with a higher wattage rating.
    10. Check the power switch:
    a. With the power cord disconnected, press the power button on the front of the PC. The button should release easily and not stick in the socket.
    • If the button sticks, it should be replaced or serviced.
    • If the power button does not stick and appears to be functioning, continue using these steps.
    11. With the power cord disconnected, remove the case or side panel.
    • Follow the wires from the power button on the front of the computer to their connection on the motherboard.
    • Look at the power switch cables connected to the motherboard. If the cable has become disconnected, connect the power switch cable connector to the connector on the motherboard.
    • Replace the side panel, plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
    12. Find the defective part:
    • With the power cord disconnected, remove the case or side panel.
    • Disconnect all power cable connectors from their connectors on the motherboard and from the back of internal devices (the back of drives). Make sure to label or remember where each cable connects for future reference.
    • Replace the side panel, plug in the power cord, and examine the light on the back of the power supply:

    13. If the LED is on solid and is not flashing, the power supply is probably good and the problem is most likely caused by a defective component (processor, memory, PCI card) or a defective motherboard. Have the computer serviced, or remove the components and replace them, one at a time, to find and replace the defective component.

    14. If the LED is still flashing (it should not flash with all connectors removed), plug the power cable into a different power outlet that is known to be good. If the LED still flashes, the power supply should be replaced.

    15. If the LED light is now off, plug the power cable into a different power outlet that is known to be good. If the LED stays off, the power supply should be replaced.

    NOTE: If an electrical storm or power surge has recently occurred, then it is more likely that the power supply, the modem, or motherboard is damaged and requires replacement.

    My hp desktop computer will not turn on


    If you cant see or heard any boot up sounds, fans and especially if you dont see any power or green led lights at all ;

    If your power cord is plugged into a power strip or surge protector, power cycle your strip or surge protector by turning off and on.

    If power outlet has a wall switch make sure its on

    Check that your power cable is securely plug in to both ends

    Check that at the back of computer, specifically on the back of the power supply unit that the switch is on "1" position and NOT on the "0" position ( 1 is "ON" , 0 is "OFF" )

    Check that the power outlet is not damaged by pluging in another good known device (such as a blowdryer, shaver, lamp, radio, etc, etc) to see if its the power outlet or not.

    Can you see power or green led lights and hear the fan on but no display ? If this is the case , check your monitor connection at both ends. If they are secured open up your case and see if you can smell any burnt smell or check that all cards especially video cards are properly seated.

    Will not power up when the power button is pressed.


    Check your outlet to make sure there is power.  Use an extension cord and try at a different outlet if necessary.  If that fails, you may have a control board problem and needs to be addressed.
