LAPTOP POWER SEQUENCE

The power sequence is the exchange of voltages and signals between the motherboard chips that takes place before anything appears on the screen.

The power sequence is the phase in which the motherboard prepares itself tofunction. This phase consists of sending orders to different voltage generators from some ICs and receiving confirmations, making sure the principle integrated circuits of the motherboard are functional... etc.

The power sequence should take place in a specific order and if one signal or confirmation is not sent or received this phase stops there and nothing will work.

The power sequence is used to troubleshoot desktop laptop motherboard problems by testing voltages, because the absence of some voltages indicates problems with some ICs, in some schematics the power sequence is described which makes the troubleshooting process easy, and sometimes it is not and in this case i will tell you how to track the important voltages that you need.
