923 7HRZ ISL9237 (Figure 1)

Symptoms

Solution

If charging the battery manually (voltage injection) allows the laptop to power on then the chip on motherboard marked 923 7HRZ (ISL9237) Figure 1 is shorted. This chip monitors system power and talks to the SMBus. Replacing the ISL9237 fixes the problem.
