Laptop won't charge - plugged in too high voltage

It could. Google "Pico fuse" to see what the fuse might look like.

Here's a picture of the circuit...The bottom with the yellow tape over it is where the power comes from.

(I have tested this, and the power is coming in.)

I'm not sure what pieces to test or which to look at.

Are you sure the battery charger you found and used is the correct one for that model of laptop?

Hi Bob,

I used the AC charger before I plugged in the external battery and it worked fine.

AC charger no longer works either.

There is a 6.3A smt fuse (F4) to the right of the 2-pin connector.

Hmm.. Something doesn't look right at C488.. It is just above and right of the 3rd smallest IC which says japan on it upside down in the pic. It is also just right of the crystal that says 4.00MT on it. Looks as if the capacitor that was there exploded.

There is also a fuse just below that labeled FS on the package and F1 on the board. Check the fuse and check to see if C488 appeared to have something there before.

hmm.. Well I don't know I can't tell from the picture for sure, but what you say makes sense. What got me was the discoloration, but that could just be some crud on the solder pads and board.
