OS X El Capitan 10.11.5 MacBook Pro (15-inch 2.4/2.2GHz) Model A1226 Processor 2.2 GHz Intel Core 2 Duo Memory 2 GB 667 MHz DDR2 SDRAM Graphics NVIDIA GeForce 8600M GT 128 MB Serial Number W87305HTX91 Current Power Adapter Model A1229 85W The MagSafe plug looks like it's about ready to break off. It is the original T type plug. I would very much like to switch over to a power adapter with the L type plug if at all possible. What would that adapter part number be? Thank you guys very much!
