Short PDF of about 940 KB covering the power on/off key circuit of the Samsung Galaxy A20. A partial diagram like this is useful when a phone will not respond to the power button: it shows the key line, its connection to the PMIC or flex connector and the nearby components, such as protection parts or pull-up resistors. Measure the line to ground and compare it with the diagram to find a broken track or a faulty flex. Check that the board variant matches before replacing parts.
