The phrase "hig41uatx rev 11 schematic verified" refers to the verification of the technical schematic for the Foxconn H-IG41-uATX (Revision 1.1) motherboard, an OEM board commonly found in HP and Compaq desktop PCs (such as the HP 500B Microtower). Technical Context The Complete Guide to the HIG41UATX REV 11:

• Measure resistance across BD1 (~500kΩ minimum). If short, replace BD1 and check fuse F1 (3.15A/250V).
• Verify startup resistor R601 (4.7MΩ) feeding IC601 (TNY277) pin 1 (EN/UV). Open R601 = dead 5VSB.
