Good news that you got your netbook working again.
Following on from what Michale said, you might want to be careful thatyou don't jolt the 'book around (eg. boot of car) otherwise the wire may come loose and touch something other than the fuse, which might result in magic smoke! (not literaly but you get the idea) Perhaps it would be a good idea to solder it or get someone to solder it for you.


Michael Kintzios <mic...@ly...> wrote: Careful with the free standing wire on two counts: If the wire diameter
and material varies considerably from specification, then it may never
blow (within the right time and, or value) and so will not protect more
expensive components down the line. Also, if it is sitting outside any
container (glass or otherwise) and it blows, it may break into bits.
These could find their way across all sorts of contacts, which would be
better off without being shorted out once juice is available again.
Using a varnish you can insulate the wire before/after you solder it -
but solder it you must if you want to sleep comfortably at night . . .
