: A thread on Vlab described a laptop that would only restart after the OS loaded. The technician replaced the BIOS, changed the CMOS battery, and tested the RAM. The eventual fix turned out to be a faulty power management controller (U35) . Touching a specific resistor connected to this controller (a TPS51124) caused the board to immediately reboot, isolating the fault.
