Toshiba S855D-S5120 won't power on

I have tried the typical power cycle solution where you disconnect power adapter, battery, discharge power, reconnect and power-up. I get nothing. No light indicators, nothing. I then bought a new power adapter and that didn’t help. I then replaced the female power connector that the power adapter plugs into…because it felt loose when plugged in. That also did not help.

I just have no power. Period.

Any help/ideas is appreciated.

I did what you suggested. Now I am just waiting with the CMOS battery out. Out of curiosity, what is this supposed to do?

Just to force CMOS to reset to default. Safer than shorting.

If that doesn't work I would say it is motherboard replace time or it is toast.
