New mother board. The power section of that board probably has some capacitors that look swollen or leaking a brown substance.

SOURCE: Dell 5150 - solid amber light at the switch.

Make sure the 12v power connector is securely connected to the system board. If you open up your computer look at the end of the board that the memory modules are there is a 4 pin connector thats the 12 v Make sure thats plugged in and secure, If thats ok you have already did the removal of the memory and replaced them, take out any pci express cards and use your onboard video, if that don't work try one memory module at a time see if that works you already seem to be savoy enough to do that and try that, and if that does not work you may need a new power supply. You can check it but probally will be bad I have the same desktop and thats been a problem with these 5150 along with the mother board going out after the warranty expires. I sure Hope this helps you out,, Happy Holidays to you and yours. Hey If you need me to look anything else up let me know. Thanks again bear001

SOURCE: amber light on power button of Dell Dimension 4500

ok - the amber light of doom on a dell means one of two things - either your power supply is pooched - or your motherboard, If under warranty dell will send out a friendly tech to replace them - if not it will cost you a bit. get the price and consider if it worth upgrading instead. Contact your dell rep or dell tech support and see what they say

cheers Pete

check on system lights... what are the diagnostic lights telling you??
if the 4 lights are off you may have a problem with the led itself or the powersupply is just messing with your head.

SOURCE: Dell dimension 2400 blinking amber light

1. Remove All External Devices
2. Check the Computer's Power LED
3. If the power LED has not changed unplug the Power Cable From the Computer Disconnect All Hard Drive Power and Data Cables and power on the computer. If still no go.
4. Remove All PCI, PCI-E, and AGP Expansion Cards .
5. Remove All Memory From the Computer
6. Reseat the ATX and 12-Volt Connections . The ATX connector will be a 4 pin square connector connecting to the motherboard from the power supply and the 12-Volt Connection would be the biggest connector with a lot of colored wires.
7. If still no go.
8. Disconnect the Power Connection to the Chassis Fan
9. If the light still flashes then it could be a power supply or motherboard failure. Try a good know power supply first and if that does not fix the problem it is the motherboard. Also check the back of the tower for 4 lights lables ABCD or 1234.
Rate if useful.

How do I fix a dimension E510 with a solid amber power light?


A steady or Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Optiplex G330, i tried replacing the power supply but still is not POST and light on the MoBo is solid orange.


You replaced the power supply and still Amber(orange). Your motherboard is probably bad. An Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Since you replaced the power supply, my guess is that the motherboard has a problem.
Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Dimension 3100 turns on the power button has a steady orange light there is also an orange light on motherboard cpu and power suplly fans working but wont bot up


Blinking amber (orange) indicates a problem with the power supply inside the computer. If the system cannot boot and there is a solid amber light, this could indicate a problem with the power connections for the CPU on the system board (see "Power Problems" in your Owner's Manual).

Pc has a solid amber light when i try to turn it on now so i unplugged it. I moved the comp around and turned it on again and it had a solid green light but nothing was on. the third time it went back to...


Hi Thanks for your question
I think you are right about power supply. This would be my diagnose. Be careful with your PC because faulty power supplies may fry your motherboard. I would recommend replacing it. This isn't expensive and it's pretty easy to get done. I hope this helps. Good Luck

Solid orange light on my vostro 200


If your fans come on full blast then you have a bad motherboard. If the amber light blinks, you have a bad power supply.

Blinking Amber light on the tower


If it is one the front near the power button, it indicates power supply is failing...and other indicator is the motherboard is failing.
Now if it is in the rear where the ethernet cable hooks up...solid amber means you are connected, blinking amber means activity on the line...no problem there- very normal. I hope it is in the rear.

No display on screen and solid amber light on pcs' power button


Well hate to say it but that sort of problem results from a faulty motherboard or processor so if you say that you have changed the motherboard then you problem lies with you processor chip.
