     DELL BIOS's Case

Note:  Dell computers may give you only one pattern of beep code "Beeeeeep".

Note:  "1-1-2" means that the code goes like "Beeeeeep" "Beeeeep ""Beeeeep Beeeeep" and it stops.

Note: Some types of Dell desktop computers may have the Diagnostic Lights, which consist of four  LED lights on the back panel.  The pattern of the lights indicates where and what the trouble is.

 

Note:  If resetting the memory card(s) or upgrading memory chips is in no effect, contact Dell technical support.
