It has a removable battery. Just turn the knob with a quarter and it pops right out.

I had Snow Leopard on there before the disk died, but it was an upgrade from Leopard. Not sure what it originally came with because it was donated.

I can pop the drive in a USB caddy and install it on my MacBook Pro (2010). That was my next attempt.
