If a laptop won't turn on, use the boardview to identify test points for input power (19V) and standby voltages (3.3V/5V).
You can find the LA6582P boardview, often accompanied by the schematic diagram (PDF), on specialized repair forums and Telegram archives. la6582p boardview full
But the boardview showed the signal path. He probed the test point. 0 volts. If a laptop won't turn on, use the
