I have a toshiba notebook (5205-5705) at work that the employees use however somone used another toshiba notebook power cord that just so happened to be 19 volts instead of the 15 volts that it is supose to use. I guess what I am getting at is I think the power supply blew from plugging the wrong cord into it. I was wondering if know if thats what might have happened because it won't power on now even with the right cord. If it is that is it easy to replace and if so where can I get a power supply for that notebook?
I'm not sure if the internal overload fuse was blown because the wrong cord was plugged into it or not. If thats what it is I also wondering how I would go about repairing that myself.
I would really appreciate the advice. Thanks in advance.

Hi wadeb_21.
Will it power up on battery power only?
Laptops don't have power supplies like desktops. The AC adapter does the conversion.
If it will not power up with only the battery connected, chances are the system board is damaged.
If it does power up under battery power only, it could very well be the power jack itself is hosed.
Here is a picture of it. The white plug you see on the other end plugs into either a seperate power board, or directly to the system board.
To test it or replace it requires virtually complete dis-assembly of the laptop.
To get an idea at what you would be looking at, see page 2, step 16 here. It's the thick black wire down the middle taped to the cooling fan.
Although this a dis-assembly walk through for the 5105, it should be nearly identical for your 5205.
I've had dozens of Dell and IBM (lenovo) laptops completely apart but very few Toshibas, except for the very old ones. Wether or not there is a seperate fuse in there or it's built-into the power jack itself, I cannot tell you.
