Question about Dell Dimension 4700C PC Desktop

1 Answer

Standby light on my dimension is blinking amber and will not boot up. Nothing will run. Any ideas as to what may be wrong. I'm thinking either a power supply or possibly a HD failure.

Definitely not a hard drive problem. It would boot, but not go to windows. This is one of two things. Power supply failure (most likely), or one of the RAM sticks went bad. I would try testing the RAM by taking one out, and trying to turn it on. Do this with both, or all four (depending on how many you have). If it still doesn't work, I would think that the Power Supply is the issue.

Dell has a set of codes that would tell you what the exact error would be based on the blinks of the amber light. If you find the pattern, you can look that up. In my professional experience it's normally the power supply.

Please Rate. Thanks.

Dell dimension 8400 blinking amber light ethernet port


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.

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 dell dimension 2400 goes on standby automatically.


If the power LED on the Tower is blinking amber, then most likely the power supply in the tower is failing. Replace the power supply.

I turned on my Dell Dimension 4700 computer,but the amber light started to blink . I held the start up button for 5 seconds and the light went out. I tried to start it up again and got the same thing,...


Vaughn it sounds like the power supply is going bad, try another known good working power supply. If that doesn't work then the motherboard would need to be replaced. If the power supply isn't giving the correct voltages that could cause the computer not to turn on. If the motheboard isn't able to convert the voltages properly then the motherboard could be faulty.

Dell dimension 5150 blinking amber lights


I have similar problem these days. After normal shutting down the PC, it can not be powered up again, the amber light blinks. A temp solution for my case is by doing these steps:

1. leave all monitor, network, keyboard and mouse etc. connected
2. disconnect the power, wait until green light and amber light dim.
3. pop up the CMOS battery, then put back in (better to check its remaining voltage, if not good, change a new one)
4. power amber light flash shorter and lighter
5. disconnect any USB connections like keyboard and mouse,
6. immediately connect keyboard and mouse back into USB ports
7. my pc powers up at this point, all green lights shining. Except it displays CMOS setup warnings, give me options to click either F1 or F2
8. I click F1, it goes into normal login XP

The only problem is I could not shutdown PC again, if I do, then I have to repeat 1-8. I have to use "Standby" instead, which I usually do.

Can't boot up Dell 5100 Dimension, amber light flashes


When you mean the amber light, is that the blinking hard drive access light or the power light? Different cases have different colors on it. Mine has blue and green lights.

If you see the boot screen (bios) and then after it goes to boot, does it blink and hang?

This could be a simple operating system issue, hard drive or hardware/motherboard issue. If you could provide more information, that would help.

Computer turns on but now booting up


Make sure the memory stick is securely installed on the motherboard. Also make sure that any additional cards in the expansion slots are also securely installed.

I had a similar problem on another machine and it was due to a memory stick that wasn''t fully secure, I reinstalled the memory stick and made sure it was a solid connection and it resolved my problem.

Please let me know if this helps you.

Loooong boot time


A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. 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.

Hi,
To help you better , could you let me know , when the system goes into sleep mode, the power light in the front of the tower is it amber or blinking amber or is it of some other color.

If the power button is blinking amber , the power supply on the unit is going bad.


Thanks
