SOURCE: Dell Optiplex gx280 shuts down and orange power light blinks

It happens because the power supply is overheats and computer goes to standby. The power supply is 160w or lower. Specially it will happen if you put more devices in such as video card or sound card. So the only solution you have is to place a small 1or2 fans toward the power supply to make it cooler. And 1 more thing the power for the fans should come from other sources.

SOURCE: Dell (ie optiplex 330) would not boot with the orange light on

Do you have a lot of accessories plugged in? They may have overloaded the power supply and if this is the case you will need to buy new power supplies. If this is not the problem, check to make sure that the computers have plenty of ventilation in the back. If they don't, they may have overheated and melted quite a few different components.

SOURCE: OPTIPLEX 960 error codes 1 and 3 at startup

Blinking amber ... seems like an isuue with the power supply .. check if you see the power supply fan spinning at the back of the system tower... If its spinning then you could try reseating the memory modules inside the system tower . Opem the tower and then disconnect the green colour ruler shapped modules which has a latch on either sides. then try turning in the system ... check if turns on properly.

Hope its informative.

SOURCE: Dell OptiPlex GX620 starts up then shuts down repeatedly

Try this: remove the DMOS battery and unplug the on/off switch plug. It's the one in the corner near the power supply. To be sure follow the cable from the front on/off switch board on back to this plug. Then plug the A/C cord in, if the system boots up fine, then replace the front panel power on/off swith board. Naturally you will not be able to power off the computer using the power switch (since we unplugged it), so you will have to just pull the plug. Hope this helps. Joe

Error light code 3 & 4 in front panels


Hi Carlos, error code 3 & 4 is caused by faulty RAM (Memory modules) installed in the PC. You could try the following to resolve the issue:

1. Open up the computer cover
2. Locate the memory module(s)
3. Remove them memory module(s)
4. Use a can of compressed air or spray contact cleaner onto the center of the DIMM connectors to clean all the contacts. Do NOT use a normal brush to clear dust away. Wait for 5minutes for the contact cleaner to dry.
5. Reseat the memory module(s)
6. Turn on the computer and check if codes 3 & 4 still light up. If it does not, it should boot into the Operating System.
7. If codes 3 & 4 continues to light up, you will need to run a memory diagnostic test to determine which of the memory module is faulty.

Log in to: http://www.dell.com/support/home/us/en/04/product-support/product/optiplex-960/diagnose and send this info to Dell. As I recall lights 2,3,4 are either memory or HDD failure.

OPTIPLEX 960 error codes 3 and 4 at startup. Solid amber light.


"optiplex 960 error codes 3 & 4 at startup"

Found out by myself the google suggestion to look up the Dell Diagnostics page:
http://support.dell.com/support/edocs/systems/Op745/en/UG_en/trouble.htm
Lights 3 & 4 means "Memory modules are detected, but a memory failure has occurred." Bingo! I didn't actually replace memory sticks, but pulled them out and put back in one by one. Only three out of four sticks were accepted. Works.

Hey, My Dell Optiplex GX270 will run for a quick second, beep, and then a light with a barrel looking icon lights for a second too. How do I fix this? Thanks so much!


I would run diagnostics. Here's how you do it if the utility partition exists on your hard drive:

Starting the Dell Diagnostics From Your Hard Drive
  1. Shut down and restart the computer.

  2. When the DELL™ logo appears, press <F12> immediately.

NOTE: If you see a message stating that no diagnostics utility partition has been found, run the Dell Diagnostics from your Drivers and Utilities CD.
If you wait too long and the Microsoft® Windows® logo appears, continue to wait until you see the Windows desktop. Then shut down your computer through the Start menu and try again.
  1. When the boot device list appears, highlight Boot to Utility Partition and press <Enter>.

  2. When the Dell Diagnostics Main Menu appears, select the test you want to run.
