PDT - 1 + 3 BEEPS ON POST, NO DISPLAY : Ace Computers

PDT - 1 + 3 BEEPS ON POST, NO DISPLAY Print

Modified on: Wed, 18 Oct, 2023 at 10:59 AM

PROBLEM:

WHEN TURNING ON THE PDT UNIT THERE IS NO DISPLAY OR POST

SYSTEM EMITS 1 LONG AND 3 SHORT BEEPS

SOLUTION:

THE ERROR INDICATES THAT THE SYSTEM CANNOT DETECT A DISPLAY CONNECTED TO THE PC

CHECK TO MAKE SURE THAT THE MONITOR IS CONNECTED TO THE INSTALLED GRAPHICS CARD

NOT ALL MODELS SUPPORT ONBOARD GRAPHICS EVEN IF PORTS ARE PRESENT ON THE MOTHERBOARD

IF A DISPLAY IS PROPERLY CONNECTED TO THE VIDEO CARD AND THE ERROR PERSISTS:

MINIMIZE ADAPTERS BEING USE TO CONNECT THE MONITOR, ONLY ONE MINI-DP CONVERTER AND CABLE

SWAP CABLES AND CONVERTERS WITH A KNOWN GOOD COMBINATION

REMOVE AND RESEAT THE GRAPHICS CARD
