Specs: Windows, Intel core i7
The screen is black. It appears to be dead, except there is still life because the light under the power button will still come on when I press it, along with the number lock light. I have held the button down for varying lengths about 20 times, from 1 to 60 seconds. The light under the power button will flash 5 times, but nothing else. I removed all power sources, including the battery, but it is still doing the exact same thing. Any suggestions ??? PLEASE help!!! I need my computer!

Have you tried connecting an external screen or perhaps TV?
Could be your laptop screen or GPU problem.

Most likely the power supply is faulty. If you know someone who has a toshiba laptop with the same power supply try using theirs and see if it loads. Otherwise take it to a shop and let them test, might have one in stock. I do not recommend buying a universal power supply, you need the proper one for your laptop. If you have a Multi meter you can unplug the power cord from the laptop and test the voltage usually 19v on toshiba.

In Canada a new power cord is $45, not sure where you live. Simple fix hopefully.
Cheers.

Thank you for your reply! No, I haven't tried that, but I probably should, just to make sure. I didn't think about that. I'm thinking it's a cpu problem before a screen problem though. A few minutes before that happened it was going real slow (when it was working). I'd have to wait and wait for it to catch up to itself. I was planning to reboot it anyway, when this happened. :(

Thank you for the advice! I don't know anyone with a toshiba laptop around here, but that's a good idea. I live out in the country from a small town in Missouri , about 30 minutes from the nearest town that will have one. I was hoping there were some magic buttons I could press to reboot it. Im fairly certain it did this one other time, and that's what I did. I just can't remember what the buttons were. It's those buttons that the factory doesn't tell you about. Lol Thank you!

Occasionally if you unplug, remove the battery, and then press and hold the power button 5 or 6 times to discharge all capacitors it will work properly when reconnected and plugged in again.
Another test you can make is to remove the battery and plug in the power cord and try powering it up again. If this works then your battery probably has an internal short and will need replacing (though further testing may be needed to confirm this).

You have to be a little bit crazy to keep you from going insane.

If it's a decent laptop, it's usually worth it. Hopefully you have a place that can test the adapter/power supply, and has one there they can try before you buy to make sure that remedies the problems.

Good luck.
