I have acer 4520 laptop suddenly turned off & not turning on at all. No led, no power up at all, completely dead. Only battery charing led woking also battery is charging ok. But laptop dont start at all.
I have checked Tps51120,it has 5v & 3.3v standby. Power button has 3v & on pressing power button I get 3.3v at RSMRST & S5-ON pin both. But cant proceed further as I dont know what to do next.
So please help me here. Is it fault of tps51116 or nvidia chip. How to find?
