HP Recommended
Product: Probook 650 G1
Operating System: Microsoft Windows 10 (64-bit)

Hello, I recently purchased a used HP Probook 650 G1 Laptop and was reading about the different possible upgrades for this laptop and noticed that you are able to swap out the DVD±RW SuperMulti Double-Layer Drive for a Blu-ray R/RE DVD±RW SuperMulti Double-Layer Combo Drive.  I looked in the service manual and there are three different spare part numbers for the Blu-Ray drive (749959-001, 739999-001, 744820-001). My questions are, what is the difference between those three spare part numbers for the Blu-Ray drive?

Thank you,
