Working replacement
works well, be careful with Lithium batteries, especially during charging.

Nice case
I like this case, it has two compartments and room for two bows. It protects the instrument in a shell covered with fabric with a full perimeter zipper.

I got this laptop just to run one piece of code, but it ended up being a nice coffee-shop portable.
Sturdy construction is worth something compared to more recent HP offerings which are just delicate polystyrene-feeling inside, waiting for one wrong move...
