Compaq Elite 8300 all-in-one
I have four of these computers that will not complete POST. They produce an error code of a solid red power LED and five beeps. This actual error code does not exist in the HP Maintenance and Service Guide under heading “Diagnostic front panel LEDs and audible codes”. Power Supply tested good (fans run); replaced SODIMM with known working module; replaced CPU with known working CPU.
Is this a good question?
