Hi all,
I have problem with this laptop. Is completely dead. Power IC was very hot I replaced it with I mean good replacement from other dead board. uP1589q I replaced it with JC (RT8239B). There are 3.3V and 5V ALW rails now. But DC-IN voltage is not stable. After second mosfet I have weird readings and something clicking. There is no short on 19V power rail. Very weird fault for me. Can someone help me with this, or schematic is availible for this motherboard? I have only boardview.
Thanks for any answer..
