Question about Dell Optiplex 755 Desktop Desktop Computer
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.
