This is often a deeper hardware issue. Repair logs have shown success by focusing on the Southbridge chip (ICH) , a vital component that controls communication between the processor and other parts. In one reported case on a forum like 91xiu, the motherboard appeared dead (0.02A current draw). The root cause was traced to the Southbridge failing to send crucial power-on signals. Reballing or replacing the Southbridge chip successfully resolved the issue and allowed the laptop to boot perfectly.
