I have a Toshiba Satellite C655D-S5533, Windows 7. The power cord became separated at the plug going into the computer, so I ordered and received a SuperPowerSupply model SPS-LA-65. I plugged it in and started up the computer, seemed fine, got onto the Internet and into email. Then computer went dead, no lights indicating power. I removed and replaced the battery, nothing, also tried without battery, nothing. A friend spliced the original power cord together, verified power with meter, nothing. Behavior seems to indicate blown fuse, could this be the problem? If so, can it be replaced? Thank you for your kind consideration.
No, there is no internal fuse, unfortunately- because this sounds like a dead motherboard. the aftermarket power supply could have been over-volting, or delivering unsteady power- burning the motherboard.
OR the old power supply shorted, and blew the motherboard's power circuitry, and you were just running off battery power when you first got the replacement.
please keep in mind that, at times, the physical power input jack on laptops can also break, or come loose from the motherboard.
