This MacBook Pro 15-inch laptop was released in early 2008 with an identical case design as its predecessor. It shipped with a 2.4 GHz Core 2 Duo (Penryn) processor and 2 GB of 667 MHz SDRAM. It contained a 200 GB hard drive and 8X DVD RW/CD-RW SuperDrive. The display was an LED-backlit 15.4-inch widescreen at 1440×900 resolution.
Although the external case did not change from the “Santa Rosa” processor version of the laptop that preceded it, the keyboard design removed the numeric keypad accessed using the fn (function) key and replaced the right-side enter key with an additional option key, the same laptop keyboard layout still in use now (as of February 2020). This MacBook Pro also used the same trackpad design as the MacBook Air of the time, adding multi-touch gestures.
Ports on this MacBook Pro included an ExpressCard slot, Gigabit Ethernet, FireWire 400, Firewire 800, two USB 2.0 ports, optical digital audio in/out, and DVI out. Wireless connections included AirPort Extreme (802.11a/b/g/n) and Bluetooth 2.1. It also included an iSight video camera and MagSafe power connector, both standard at the time.
When I acquired this laptop, its battery had burst while installed in the laptop. The battery failure caused the battery to bow in the center and it was lodged in the case. Using a few iFixIt spatula tools, I was able to extract it safely and then properly dispose of the ruptured battery.
