Del 320 optiplex orange lite blinks won't boot up

please describe in more details, whe you try to restart machine from os or from button?

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.

check the ram.change the slot and disconnect the hardrive before that

I would suggest to go to Fred Meyer or an equivalant store and go to the electronics section. Find a new DS Lite battery.

Hi there!

A blinking amber/orange light on the power button of your Dell Optiplex means a hardware failure. If you know how to strip down your computer to basic component, then I suggest you turn on with only the motherboard, processor, memory and PSU. If you are not familiar with this, I suggest you bring the computer to a qualified technician.

Hope this helps

An amber led is indicative that your machine is stuck in either stand by or hibernation mode. If you're unable to boot up at all, the easiest way to clear it is to

1. Unplug the machine
   
2. open the machine, remove the CMOS battery for several minutes
3. while unplugged and with CMOS battery out, press and hold the power button for 5 seconds
4. re-insert the CMOS battery
5. re-assemble the machine and plug in
6. press power button and allow machine to run diagnostics

At this point it will try to run in SAFE mode. Once it boots up successfully, you should be good to go.
Best of luck!

Try changing the processor and see, it really worked for me

If you are getting a blinking amber light this is normally related to a power problem. So the first thing I would try resetting the flee power. You do this by unplugging the AC power and holding the power button in for 30 to 45 seconds. After you do this plug back in the AC power to see if the system will boot. If it will not the next thing I would look for is the diag lights to see if any are lite up. They are normally near the front USB unless you have a small form factor case then they are on the back. Then will point to a hard ware problem if any. If they are not lite up then most likely the problem is with the powersupply.

Note if you are still in warranty I would pass this info over to Dell and they should be able to get your system fixed.

Let me know if you have any more problems or questions.

In addition to the power supply, motherboard issues can cause the blinking power light and no boot problems. The Optiplex 270, 520, 620, 745 and 755 units are all known to have issues with capacitors on the motherboard. Here is a link to an article about this issue and what to do about it:

There was problem at one time with IOGear KVMs not working correctly with the USB chipset on the Dell motherboards. This problem was resolved by using a USB hub between the KVM cable and the computer. The user could take the USB portion of the KVM cable and plug it into a USB hub and then take the USB hub and plug it into the Dell computer. That should help with the problem.
