I have a Toshiba Satellite Pro S500 Laptop that won't start. I bought a new power jack and installed it into the laptop and tested it with a voltmeter, it works fine, and the laptop did in fact start up with the new adapter and power jack. A couple days later I try to start up the laptop again, but it won't start. I took the laptop apart again and tested the power jack and also tested the power adapter, both are working fine so I don't know why the laptop won't start up again.
Edit: It seems the mobo is dead, will have to purchase a new laptop.
