Spark and smoke - what have I done?!

Replacing the screen, I left the power on and got a spark and a whiff of smoke when connecting the LED lead to the terminal on the back of the screen. Now the laptop won't power up.
Is it just the fuse in the laptop that's gone or have I done something major?

could be anything, they do say turn everything off when you connect things

"Now the laptop won't power up."

Any fans running ? any sounds?

No sounds and no blue lights on the laptop where previously there were.

Not sure if you have a fuse on the main power connector but may check that first or check with it just using the battery.

If your motherboard has a fuse, it should be very near the power jack (where you plu in.)

Just checked it at PC World - nothing wrong with the lead. The guy reckoned it may be the motherboard.
They charge a flat fee of £230 to fix!!!!!
Insurance excess is £100 but I've already forked out £55 for the screen.
It's a Toshiba Satellite btw.

Yes, but is there a fuse?

You need to find that and replace it

If that doesn't solve the problem then it's likely you've blown something major

You mention insurance, but does that actually cover you working on the machine?

IMHO, given that you left the power on when replacing the screen you possibly aren't competent to deal with these things, so maybe you'd best take it to a professional.

Fuses don't smoke !

I doubt you will find many that will repair to component level on a circuit board.

Sorry it's not good news.
