My Toshiba l20 starts immediately i plug in the charger and nothing come on the screen also all the indicator lights( I mean the power, charging, HDD lights) will still be off. in this state i can still switch it on and off with the power bottom.
I have been to some sites which say, the problem is due to a dead chip called "MOSF power switch". Now my problem is how to locate this chip/chips on the board and replace them with new ones. I have the neccessary equipment and skills to change any kind of chip.
I will be happy if someone help me to loacate this "MOSF power switch"
in most cases it is too expensive to just replace 1 chip on the motherboard and is cheaper just to buy a new motherboard. but if you are doing it yourself it might not be that bad. i would suggest getting a hold of toshiba and see if they can give you a schematic of the laptop hardware. normally tech support can give you something to go on.
