Have you check the power cable connection..? Test the cable with other cpu and see weather it's still good or not. If the cable is still working, maybe your power supply is damage. If it the power supply, then you need to change it with a new one. If it's still not working, maybe you shoukd also check the on/off button. By the way, did the fan running when you turn your pc..?

    Well :-) 1st i thought your cpu can not turn on but now i think it's your monitor, right? Well, if it's really the monitor that can not turn on, i suggest that you;

    1) check the monitor power cable - try the cable with another monitor/cpu to see weather the cable is ok or not.

    2) check your monitor - connect it with another cpu with the same cable & with different cable.

    3) change the vga card

    4) change the vga card to another pci slot.

    Good luck ;-)

Your problem may have several root causes.. but the most likely one is that your power supply has failed and needs replacement... (I'm assuming you don't see any lights when you try turn the computer on after confirming the computer is in fact plugged to a working wall oulet)

post back with your findings

    jeremiah.. so your computer does turn on, based on what you're saying... is the problem the fact you don't see any picture on your screen???, is your monitor (power and cable) properly connected??

    when you turn your computer on..do you hear a beep (normal) or do you hear a serious of beeps (abnormal)??

    have you try to connect another monitor to see if you get a picture??
    based on your replies I'm thinking your monitor has gone bad on your video adapter is crapping out.



    please post back.

Can't turn on power to desktop


Simple power hack, to do this, kind of like hot wiring your computer.

Turn the power on at the wall, Flick the switch on the back of the computer (if there is one on the back) to the on position, make sure the cable is plugged in, and turn the power off at the wall, hold the power switch on the front and turn the power on at the wall.

This will cause the power to jump across the switch, causing the computer so sound a bit like a motorbike being started.

The power will come on it will turn over click and go off. After this turn the switch of at the back of the computer, and turn it back on, and the computer will boot up.

The first bit of this is just charging the capacitors in the power supply, the second bit is turning your computer on.

2. Take the battery out of the computer.
3. Unplugged the ac adapter.
4. Press and hold the power button for about 30 seconds. (without any power source)
5. Put the battery back in and plug the ac adapter back into the computer.
6. Turn the computer back on.

If this computer is a desktop:
1. Turn the computer off by pressing the power button for a bout 5seconds.
2. Unplug the power cable from the computer.
3. Press and hold the power button for about 30 seconds. (without any power source)
4. Plug the power cable back into the computer.

Gateway mx6448 Notebook will not power on, Red LED flashes 4 times when power on button is pressed then nothing happens. It is the same with only the battery. LED will not flash if I have only the power...


There can be many things associated with no power to the computer.
  • The outlet into which the computer is plugged may be inoperative.

  • The surge protector you are using may be inoperative.

  • The power cable may be loose or damaged.

  • An internal device may be damaged.

  • The power supply may be inoperative.

Basic Troubleshooting Power to the Computer
There may not be a consistent flow of power to the computer.
  1. Verify that the outlet into which you are plugging the computer is operational.

  2. If you have the computer plugged into a surge protector, plug it directly into the outlet.

  3. Verify that the power cable is plugged securely into the back of the computer.

  4. If you have a monitor with a removable power cord, swap the power cords between the monitor and the computer.

Note: If you recently added a new hardware device prior to experiencing the no power issue, turn off the computer and remove the newly added hardware. If there is still no power, reseat all the other cards and cables in the computer to verify that all other devices are seated securely.
Resolving Power Supply Issues
  • External Device Conflicts
  • There may be an external device causing the computer not to turn on properly.

    1. Before continuing, verify your computer is turned off.

    2. After you have established that adequate electricity is going to your computer, verify that the voltage switch on the back of the power supply is set correctly. The small red switch is to be set to the 115-volt setting.

    3. Remove all external devices except the monitor and turn on the computer. If the fan on the back of the computer now spins, turn off the computer. Plug in the external devices one at a time and turn on the computer after each device is added.

    4. Note: If you removed all external components and the fan on the back of the computer does not spin, the problem is with something inside the computer.

  • Internal Device Conflicts
  • This helps determine if the issue is a damaged or badly seated component.

    1. Verify that the computer is turned off.

    2. Remove the case from the computer.

    3. Remove all the red, yellow, and black power connectors from each floppy disk drive, CD-ROM drive, and tape backup unit that is in the computer. The only devices connected to the power supply are your hard disk drive and motherboard.

    4. Turn on the computer and verify that the fan on the back of the computer spins. If it does not spin, turn off the computer.

    5. Remove the power connection from the hard disk drive and reconnect power to one floppy disk drive. Turn on the computer and verify that the fan on the back of the computer spins.

    6. Reseat the power connection from the power supply to the motherboard. Turn on the computer and verify that the fan on the back of the computer spins. If the power has been restored, turn off the computer and reconnect the power connections to the devices. Test the computer for power after reconnecting each device.

  • Power Switch
  • The power switch may not be functioning properly.

    1. You may need to open the case and readjust the power switch.

    2. Locate the control panel inside the computer and remove any screws holding it in place.

    3. Turn on the computer with the control panel removed by pressing the button on the control panel that corresponds to the power button. If the power supply fan spins and/or the computer turns on, put the control panel back in its place. Try to turn on the computer again.

  • Test Switch and Diagnostic LED
  • Note: Not all power supplies have a test switch and diagnostic LED.
    Certain power supplies have a test switch and LED to help better troubleshoot the device. The green LED is always on when the computer is powered on. If the computer is not receiving power please perform the diagnostic test below.

    1. Verify that the computer is turned off.
    2. Remove the case from the computer.
    3. Remove all of the red, yellow, and black power connectors from each floppy disk drive and ROM drive and the tape backup unit (TBU) that is in the computer. Remove all power connectors from the motherboard. The only device that needs to be connected to the power supply is the hard disk drive.
    4. Press and hold the test switch for five seconds on the power supply, and then verify that the green light on the power supply comes on.
    5. If the light comes on:
      1. The power supply is good and something that was plugged into the power supply is causing the computer to not turn on.
      2. Plug devices in one at a time, testing with the test switch between each device to determine what is causing the power issue.
      3. If all devices are plugged in and the light is working, the connections may have needed to be reseated, or it is possibly a power switch issue.
      4. Go to the power switch section of the power supply checklist for additional troubleshooting steps.

    6. If the light does not come on:
      1. Disconnect the power from the hard disk drive, and then plug in power to the CD-ROM drive and determine whether the light comes on.
      2. If it does, follow the preceding information - "If the light comes on."
      3. If the light still does not come on, contact Gateway Technical Support.

    7. Confirm that power from the power supply is connected to the motherboard. Remove all cards and cables from the motherboard, and press and hold the test switch for five seconds on the power supply and determine whether the green light-emitting diode (LED) comes on.
    8. If the LED comes on, put the devices back in one at a time, testing between each device to determine what is causing the issue.

My dell dimension computer won't turn on. When I push in the button, it only flashes orange and then won't turn on.


Plug the computer into a power strip that has an on/off switch. Turn the power strip on. Press the computer power on button to start as normal, but after after one second turn off the power strip switch just long enough for the fans on the computer to slow down, but the amber computer led doesn't turn off and then turn the power strip switch back on. Computer should start and run fine. Computer typically can be shut down for up to 5 minutes and restarted normally--any longer and you have to sue the power strip power switch routine again

My HP Pavilion M90 monitor won't turn on. Every time I press the on button I hear a clicking sound from the back of the monitor. It sounds like it's trying to power up but it doesn't do anything. Is there...


Hello

Do a hard reset on the laptop by removing all cords and connections from the computer, including the power cord. Turn the computer over and slide the tab next to the battery, then lift the battery out of its compartment.

Eject any SD cards currently inserted in the SD card slot by pressing on them, then remove them from the slot completely. Hold the computer's "Power" button down for at least 15 seconds, then plug the power cord into the computer and turn it on.

Watch to see if the LED lights near the "Caps Lock" and "Num Lock" illuminate. If the lights do not turn on and the computer's screen remains blank, inspect the power cord and AC adapter for damage and replace them if necessary.

Leave the power cord plugged into the computer and snap the battery back into its slot. Allow the computer to sit for at least 30 minutes, then unplug the power cord and press the "Power" button again to see if the computer will turn on.

Plug the power cord back into the computer and try to turn it on again. If the computer turns on, replace the battery with a new one. If the computer still does not turn on, take the computer to a repair shop.
