Abit AN52S not boot repair 
This motherboard failure as a standby voltage lower
Measured switch voltage of 1.9V A14 at pin 0.9V voltage lines run from the switch at W83304CG 35PIN to look for materials that enter the post-test W83304CG 41PIN (5V SB) is only 1 point a few volts, the normal should be 5V, because of this pin voltage is abnormal lead to the standby voltage is not normal. As customers rush and had not pitted line, directly from the Violet 5V pull a line in the past to connect to the W83304CG 41PIN, test-retest all normal standby, turn all the way to run code. Oh, light machine.

The latest progress in this plate:
Later, my client is because too much force ripped the fly line to the (not know whether it was deliberate)Also get it back rework, but fortunately, this time he was in no hurry, so I slowly began to investigate, then found one not far from the W83304CG Short diode is damaged, lead to the 5VSB damaged, replaced all normal.
Short diode position in the second pictures inside. SATA interface on the top side of that capacitor. From the chart you can clearly see that the bird leaning against the board edge.
