I have a toshiba satellite l655 that the power dongle was broken because the power cable got yanked out of the hole and it broke the plastic inside. The laptop ran until the battery ran down. I purchased a new cable and installed it but the laptop will not power on. I get no power light to signify it is plugged in or a battery charging light. Thinking that it was probably the motherboard got shorted during the whole ordeal, I purchased a new MB. I replaced the MB and still the same issue. I have tested the voltage all the way to the MB and it has a solid 19v all the way. I have tried to power it on with only the power adapter plugged in, I have pulled the cmos battery. I have tried the "hold the power button for 30 sec" trick. Everything logically should work but it is just unresponsive. Any ideas???
