    Nela 4 laptop not turrning on

    Hay to all . I've got a question about a fresh recived laptop for spare parts. So i was looking to fix it and got on a "no start even if i press the button for it". So i took it apart, everything was clean and nice exept the chip "iTE IT8512E 0813-CXT ME8LKC L". If plugging the dc in the motherboard it would raise it temperature (the chip) to +100C. Is that the malfunction here? And if yes where can i buy the exchange part?

        you would have to compare data sheets of the said ic to make sure they are internally correct, if you were to use diffrent brand ic..

            "iTE IT8512E is a kb control ic which also responsible for system on/off function. But to be sure you need to check from the board schematics. and its not interchangeble.

              Ye it is for on/off function, and without pressing the button for turn on it raises it temp to 100+C.
