Are you sure the ac adapter is providing power to the system? You should check it with a multimeter first before ruling out a problem with the system.

    Then ya, probably motherboard. Ebay is the easiest place to purchase. As for site with help, unless you are or know an authorised Toshiba tech, it could be hard to find the proper disassembly guide. I don't have access to them, but you never know what a Google search can dig up.



    Otherwise you can just take it apart being very careful to note where all the screws and cables go. I like to make a sketch of each section and mark the size and position of all the screws. That way you can put it back together.



    Start with the bottom screws, then the keyboard, then the screen, then the palmrest, then the motherboard.

Toshiba Laptop Satellite C655 will not power up


Take out the battery and only hook up the AC Adapter into a normal working outlet. Push the power button and if it turns on then you know the battery is bad. If you still dont get the laptop to turn on then either you have a bad AC Adapter or the motherboard is bad and would need to be replaced.

Toshiba satellite m55-s135 won't power on even when plugged in


When the AC adapter is plugged to the wall, if it has an LED make sure it is on, remove the battery and connect the adapter to the laptop, does it power up?
Install the battery after charging, see if your laptop powers up.
If the laptop does not power up, the motherboard needs replacing.
I hope this helps to resolve your issue.
Good Luck.
