    I have an inspiron 518 that won't power up. The green light on the back is on and an amber light on the motherboard is on. Nothing else is on. Was told I needed a new motherboard, replaced it and had the same problem. Then was told I needed a new power supply box, replaced it and still no change. Any suggestions. Thanks

Have you tried the blow dryer trick? I know it sounds crazy, but it has worked for me on my Dell Inspiron and HP Pavilion. Before you spend any money on replacing anything, try this... Blow a hair dryer into the fan of your power supply, on hot, for about 30 seconds to a minute. Then turn your computer on. That's it. I learned this trick while searching for a fix for my HP - when the power supply green light was flashing. But it also worked on my Dell when the power button was flashing amber (when depressed) and wouldn't power on. You can search the web for 'power supply blow dryer' and find videos, etc. I didn't need to disconnect anything.

Would you mind if I ask you another question? Can you see it boots upto Bios display? If you can, please let me know how many rams sticks are installed on it. I hope you've connected both the power connectors. Many people make mistakes with the 4 pin power connector so they left it unconnected, and blaming other components. Without the four pin power connector, it'll never boot up only with the 20 pin connector alone. It should be connected backside of the box below the smps and behind the cpu/heatsink. If you are sure with this, the proceed. Now unplug all the external devices like usb, audio/speaker wire, ethernet. Connect only the keyboard, mouse, power cord and display/video, etc..etc... Also, unplug the internal usb, front audio, and the front panel connector, unplug the hard disk, Dvd/Cd-Rom, etc..(what I want it with only the Processor and Ram installed) .

Power on the mains and check if you can see the light on the motherboard is lit or not, if so, take a screwdriver and short the two pins of the front panel power connector (I hope you understand what i mean, if not just reply me so that I can use a labelled photos or something for your references). If it's not working, you better check the ram once again. If possible replace it with new one and try again.
Or if it's working fine and you can see that it boots upto the Bios display? then put back the components one by one while you keep booting up the system everytime a hardware is connected, that'll help you find out the culprit.

I am aware that your cabinet is the cause, means the the front panel connectors on the cabinet, let me know when you are done.

I am not done yet, but since it's better to give step by step solution than one go solution, I would await your response. Thanks.

This sure sounds like a power supply problem to me, and someone in a blog mentioned possible bad memory, but an accessory could be loading it down. Try a different power supply, and if that doesn't help, disconnect auxiliary boards and see if you get a power up. Other than that, I can't think of what it could be unless the hard drive could affect it.
Actually, I just ran across a blog about checking the PSU unit, and here is a video explaining how:

This may be your problem. Good luck, and hope this helps you.

Dell Inspiron 518 Solid Amber light on power button. My power went out today and i turned my computers back on and this happend. All fans are running.


Your computer has failed the Power On Self Test.

Be sure to check all external connections as well as the connections within the computer chassis. Clean the Gold fingered connections of the RAM modules and Graphics card with tissue paper.

Also go through my published guide entitled, My Computer is not turning on!!! Is it dead!!! No POST!!! for additional help and information.

You may need to clear the BIOS/CMOS.

Take care!

Will not turn on when power button is Dell Inspiron 518 will not turn on when power button is pressed. Green LED on back of powersupply lights and orange LED on motherboard turns on. No fan operation on...


Green LED on back of power supply indicates it's getting power. That does not mean that it's distributing the power voltages to the computer. You could have a bad power supply or a bad motherboard. Just to make surethat nothing else is causing the problem, remove any PCI cards like modem,video card, sound card, etc... Remove the memory modules and disconnect cablesto CD/DVD drives. Look at the USB ports to see if any are damaged.

My Dell inspiron 518 will not turn on when power button is pressed. Green LED on back of power supply lights and orange LED on motherboard turn on. No fan operation on anything. Thinking it is the switch...


Green LED on PS means it's getting AC power. Orange light on motherboard means it's receiving power from PS but it may not be the correct voltage. The power supply isreceiving power from the source but is unable to properly distribute it to thecomponents. This can be caused by a defective power supply or a defectivemotherboard. Just to make sure that nothing else is causing the problem, removeany PCI cards like modem, video card, sound card, etc... Remove the memorymodules and disconnect cables to CD/DVD drives. Look at the USB ports to see ifany are damaged.

My inspiron won't power up. Only green light on back and amber light on motherboard work. Have replaced motherboard and power supply box. Also checked and cleaned ram. Any other ideas?


There are a few things you can try. I've had similar problems like yours and went through the whole tower but it ended up being a currupt drive. You say that it won't power up, but is the fan on and the hard disc spinning. If they are you may find you have a corrupt hard drive.
What I did was remove the hard drive, connected to another pc via a adapter cable and opened it up from my computer. I backed up what i needed and then formatted the drive. Then returned it the tower and rebooted and reinstalled the operating system. It has been running fine ever since.
There are others that will recommend different ways, but to me it was easier and i lost no data and my pc is like a new one.

My dell inspiron 1520 does not work at all, power


no this is not a defect this would indicate that the power supply has failed on your pc.. look at the back of the unit if the power supply light is amber in color or blinking thne there is your issue.
