    I am working on a Panasonic Tough Book with Windows XP. The original problem with this tough book was that the shift keys appeared to be stuck. Well I fixed that problem buy hitting the left and right shift keys in rotation for one minute. After that I was installed AVG because the client did not have any antivirus program. I had removed the viruses previously.

    Left the machine running and walked away. When I went back it was turned off. Tried to turn it back on, no lights nothing. With the power cord plugged in no lights come on indicating power connection. I took the battery out. Held the power button for 30 seconds. Connected the power cord and still nothing. No lights, no sound of anything starting.

    When I was given the tough book the client did not have the power cord, just the car charger. I used another laptop power cord that I had. Could using the spare power cord that I had from another laptop have done something? I used this power cord all day yesterday without any problems.

    Since you have what apperas to be a lack of power - it sure like like something could have been fried. Did you try the car charger?

    I was playing around....pluging and inpluging the power cord. All of a sudden the power lights came on. The power light was orange. I started the laptop and it was booting Windows. I was watching the power light and it started blinking red, shortly after that the system went dead. Any thoughts? This happened twice. Back to no lights again.

    A VERY Common issue with laptops is the ac jack on the mobo breaks. Some are easy to repair - others require new mobo's. I have no idea which catagory yours might be in. Might take it to an authorized repair center.

    Do you think it is the AC jack if the lights come on when plugged in?
    When I have the power cord plugged in (light on) and pull the battery the light go off.

    Your opening post repeatedly said no lights?? Maybe that's changed a bit.

    It seems obivous to me that there is a short somewhere? Running a power supply with the wrong rating could have melted/fried something somewhere.

    I went and got a converter for the car power cord and everything is working fine now.
    I don't think anything got fried.
