No bios no post and no power lights on disk drives means hardware problem.

Either call a technician or try the following if you feel you can do it yourself, beware , there is always risk of damaging your PC on DIY.

unplug the computer, open PC and remove all plugs and internal and external devices, leaving only a minimal set of devices.

Start the motherboard with only Power adapter , one RAM module, and video card and screen connected. Unplug all disks and external devices, remove all pci cards.

If it still does not start take it to a repair shop, you may need to replace power supply, motherboard or ram.

Aux power led light is amber on dimension E521


I think your problem is your memory or video card.

Below are some steps that I recommend.

When you plug in the power cord is there any lights whatsoever on the computer?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.


Below are links and info I found from Dell's Website based on your model.

My hp pavilion a430n is not turning on. even though i pressed the power button the light wont even turn on. it is truly annoying and the screen says something about the power supply and green, red, blue...


I suggest to open your computer and unplug your power supply and look for the color green and black cord which plugged from your motherboard. Then find a piece of wire and short the color green and black wire to test if your power supply is working and plug to your power socket. And check your electronic parts (capacitor) near at your processor, it might your capacitor blown out.

another computer and see if it boot up.to test the mother board unhook the cd drives and harddrive.turn
on the computer and see if the gateway logo comes on.if it still does the the samething with everything unhooked

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.

When comp pluged in just a green flashing light


If you are sure that the 110 volt power is coming into the computer then the most likely problem is that th epower supply died. Obtain a new one of the same or larger wattagge as the one you are replacing . It does nto have to come from the manufacture of the computer.
