Had the same problem after the electric went out due to a storm. When the electric came back on the computer wouldn't turn on. There was a light flashing on the Power Supply and on the mother board. I disconnected the large white Power connector from the motherboard, waited 15 seconds and plugged the connector back in, the light came on solid, press the on/off switch and the computer booted up and continued to work fine.

This is likely a power supply problem, the power supply probably has seen it's last, you can try and contact sony for a replacement or you can buy a PSU tester for about $25-35 and use that, another problem could be the motherboard going bad, or even slim chance of the power button going bad, I don't know how much you know about technology, but if you need further help just list a reply, along with how familiar you are with computers and how old the computer is and then also how much you are willing to spend

My HCL pc has a power problem it can't turn on


usually, either a faulty power supply or motherboard can cause this though it would also be a good idea to test other components. try the easy steps first. try another working power cord and power outlet. at times, a faulty power cord will or failing outlet are the culprit. should that not work, move inside. unplug the computer and try to disconnect all components connected from the outside of the computer, then open the casing and remove the all memory modules, add-in cards, storage devices and all connections to the motherboard. if the power supply has a LED indicator or a test button, plug it to a working outlet, then use the test button or check if the LED on it will glow to at least help indicate if it has power. If no indicators, unplug it again, press the power button on the computer to drain any power remaining. Once done, check the motherboard for visual signs of issues like leaking or bulging or burn capacitors. if none, use the reset jumpers in the motherboard, remove the cmos battery, then reconnect the 4 and/or 12 pin power to the mainboard, plug the power supply and try to power it on. if it powers like fan spins, try to power it off and unplug it after about 10 seconds. reconnect all devices inside one by one and keep testing the computer to see if any device will prevent it from turning on so you will know which component may need to be replaced. else, try swapping parts if possible starting with the power supply, memory and last would be the motherboard.

hope this helps.

Desktop will not start no response to power on button


1) you must open the desktop and look for any connector loose
2) test the power cord for open or replace
2a) Test the power button for open or defective
3) see if the switch behind is 110 or 220vca adjust it
4) Test the power supply and see if the fan are working, test the output for +5VDC, otherwise is faulty.
God bless you

Power button


You could pop off the power button cover and test it that way. I put a flathead screwdriver in the crack around the button and popped it off when I had this problem. Please get back to me after you've tried this

Dell inspiron 531s will not power on. It worked just fine and after I moved to a different home, it does not power on at all. I have tried different electrical outlets


Assuming you have tested those outlets with another electrical device (such as a lamp) and they are getting power, the problem might be the power cord, or static inside the computer. Try this:

1. Remove the power cord completely from the computer.
2. Press and hold down the power switch for 10-20 seconds. This drains any residual static in the circuitry.
3. Re-attach the power cord. Make sure it is seated firmly on the end that attaches to the back of the computer.
4. Plug it into a known good outlet and try to power on.

If that does not work, try replacing the power cord with a known good one. If it still doesn't power up, the problem could be either the power on button, or the power supply itself. Either could have been damaged during your move. You could open the computer case and see if anything appear loose, or any wires are obviously detached.

Power supply modules do ocassionally go bad on computers. They are not that expensive to buy, and not that hard to replace, though it might be a challenge for a novice. Before you buy and/or replace the power module, be sure to have the machine tested at a local store (Radio Shack, Best Buy, Office Depot, etc) to make sure that is really the problem. Many stores will perform a power supply test for a nominal fee.

No power - not responding to on button


If there are on LED lights on in the front panel then either the power cord is faulty or the switch mode power supply is faulty.
Try a different power cord to determine if it is faulty.
Can you smell a burnt electrical smell from the fan grill at the switch mode power supply?
The only way to test if the switch mode power supply is to remove it from the desktop computer and take it to your friendly computer shop to get it tested.
If you do have electronic knowledge I would advise you not to attempt to test and try to repair this power supply.
If the switch mode power supply is faulty, then replace the switch mode power supply with another unit with the same or more wattage.

Front panel Ac Switch failing to start computer.


Try these steps.
If Power supply light does not turn on (or no power supply LED)
Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:
NOTE: If the Power Supply fan spins when the PC is turned on but the light does not come on, it is possible the LED is defective. If this is the case, use the section Power supply light comes on or flashes .
1. Disconnect everything from the PC, including the power cord.
2. With the power cord disconnected, press the power button on the front of the computer. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
3. Replace the power cord with another power cord, like the one used by the monitor.
Test to see if the computer can turn on. If not, continue using these steps.
4. Ensure that the voltage selector switch is on the correct setting, 115V for North America.
5. 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.
This ensures that the voltage switch is engaged and set correctly for your country/region.
6. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
7. 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.
8. 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.
9. Use a vacuum cleaner to remove the build-up of dust from the power supply fan vent holes. Make sure that the PC is turned off and that the power cord is plugged into a grounded outlet. Only use the end of the vacuum hose near the outside of the fan entrance.
Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
10. If all of the above steps have been tried and the power supply light remains off, use the steps in the next section, use the next section Power supply light comes on or flashes , to reseat the cables and check the power switch connector.

No power to a SR1420NX.


Power supply light on or flashes Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure: CAUTION: This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.
  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. Figure 4: Voltage selector switch c00517964.jpg Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
  4. 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.
  5. 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.
  6. Remove all attached devices except for keyboard, mouse, and monitor.
  7. 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.
  8. Check the power switch:
    1. 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.
    2. With the power cord disconnected, remove the case or side panel.
    3. Follow the wires from the power button on the front of the computer to their connection on the motherboard.
    4. 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. Figure 5: Power switch connector on Motherboard c00517968.jpg
    5. 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.
