Small 12.7 KB RAR archive describing the power-up sequence of the Lenovo B460. A sequence document lists the order in which the standby rails, enable signals, power-good lines and main voltages come up after the power button is pressed. That makes it a quick reference when a board does not start and you need to find the stage where the chain stops. Pair it with the full schematic for exact component locations. Board number and revision are not given, so check that the sequence matches your B460 board variant.
