Absolutely painless, but since there aren't many steps online for the latest version of PE4C, here are mine. Steps Disable Nvidia 2000M from Device Manager Remove Nvidia driver from Programs and Features Remove any other Nvidia software before restarting. Restart Enter BIOS. Disable OS Detection for Optimus. Set Graphics adapter from Optimus to Integrated. Ensure ExpressCard is enabled in I/O subsection. Do not plug in express card yet. Allow Windows to boot. Remove all remaining Nvidia software. Consider running Display Driver Uninstaller. Shutdown Computer. Plug external PSU motherboard connector to PE4C. Attach included 8-Pin Power cord to PE4C.
