I finally got my macbook PRO (17 inch) back from applecare. It's more than three weeks. Anyway, on the repair sheet it lists the following: PCBA, 2.16GHZ, 256VRAM, M9 CBL, TEMP SNSR, RT FAN, M9 CBL, TEMP SNSR, GPU, M9 MOD, 512, DDR2 667, NANYA A, LF SODIMM I think they replaced the lb but I can't really tell. Can anyone help me out on this? Thanks!
