Del 320 optiplex orange lite blinks won't boot up



For the Optiplex 320, a flashing amber light with no sound indication can mean 3 things.


1) Your power supply has failed

2) Your motherboard failed, most likely from a bad capacitor.

3) The front panel board (where the power button is located) is faulty or not connected properly.


I've worked with 10's of 1000's of Dell Optiplex's over the past 8 years and the flashing amber light is well known as a tell-tail sign of one of those three failure. Always start your trouble shoot with a PSU tester, then inspect the motherboard for domed or split/leaking capacitors...then on to the front panel which would require another panel and ribbon from the same model.

Dell OptiPlex GX520 PC Desktop Problem


An Amber blinking power button indicates a low or missing voltage problem. 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.

I have a flickering amber light on the power button; replaced power supply and motherboard with no luck


FIRST IF YOU REPLACED THE POWER SUPPLY OF YOUR DELL PC,
MAKE SURE IS A RECOMMEND POWER SUPPLY FOR DELL COMPUTERS ONLY
BECAUSE DELL USE A DIFFERENT (NONSTARD) PS

AN PLEASE DON'T TURN YOUR PC ON, TILE YOU ARE SURE I'TS A DELL COMPATIBLE POWER SUPPLY
YOU CAN FRY YOUR COMPUTER

ON THE MOTHERBOARD I'T MAY BE THE BIOS (BIOS STANDS FOR INPUT /OUTPUT SYSTEM) I'T A CHIP ON YOUR MOTHERBOARD THAT CONTROLS THE SYSTEM HARDWARE AND ACTS AS AN INTERFACE BETWEEN THE OPERATING SYSTEM AND THE HARDWARE
I'T MAY BE FLASH
IF IS FLASH ,
YOU PROBABLY NEED TO REPLACE THE MOTHERBOARD
OR CALL DELL TO SEE IF THEY CAN FIX IT
