Testing components for resale

I have one of those too! Died of liquid damage. Right now I'm investigating component-level repair for the logic board (Rossman Repair in Brooklyn NY sounds good, but I have no experience with them).

I used the iFixit Universal Drive adapter to check out the HD - wonderful device. Planning to test the Superdrive in another laptop of similar vintage, but a standalone enclosure would probably do as well (like the a USB external optical drive from Samsung). Testing the keyboard will be tricky without a machine to swap into though.
