Symptoms of the issue:
Dell Optiplex 9020 that does not boot up properly. When the power button is pressed here’s what happens and keeps going in a loop:
– Keeps doing a single beep
– Power button blinks amber and then blinks white
– Hard Drive symbol blinks white
– PSU LED blinks green
– CPU and Case Fans spin briefly and then stop
Resolution of the problem:
completely turn off the computer
disconnect the power cable
leave the power button pressed for 30 seconds + to discharge all the funny capacitors and the energy that remains in the components
open the case cover and carefully remove all the RAM/memory sticks
turn on the computer, it will beep once, then several times (3 continuous beeps), there should not be any video on the monitor, leave it running for 1 minute and later turn off the computer
open the device again and place a single memory stick (might want to consider cleaning the memory connectors with an alcohol wipe carefully, let it dry for a minute before re-inserting). Place the memory stick into position 1.
re-connect the power cable and turn on the computer, this time there will be video on the monitor, likely with a memory change message, press F1 button and it will continue to boot.
if everything worked, turn off and repeat the steps to re-insert the rest of the RAM/memory sticks.
