Troubleshooting This chapter provides troubleshooting information for the Veriton S2720G Desktop Computer Service Guide. ⚫ Power-On Self-Test (POST) ⚫ POST Error Messages List Power-On Self-Test (POST) Each time you turn on the system, the Power-on Self Test (POST) is initiated. Several items are tested during POST, but for the most part transparent to the user.
POST Error Messages List If you cannot run the diagnostics program tests but did receive a POST error message, use “POST Error Messages List "to diagnose system problems. If you did not receive any error message, look for a description of your error symptoms in “Error Symptoms List”.
Page 46
Memory test fail If POST detects an error during memory testing, additional information appears giving specifics about the type and location of the memory error. Override enabled - If the system cannot boot using the current CMOS configuration, the BIOS can override the Defaults loaded current configuration with a set of BIOS defaults designed for the most stable, minimal- performance system operations.
