Hi.

I have here one notebook which doesn`t start. When i insert healthy charger in it(of course same Voltage and Ampers) the Universal Charger`s LED begin to blink all the time. With the charger which the woman gave to me with notebook it won`t power too but the charger has no LED indication.

The question is :
i see 4 ic near the power input. They are labeled
4684
bk (Triangle sign)
W74A
