Product Specifications

IBM ThinkPad R series notebooks pack ready-to-run essentials for frequently mobile users into a sleek, lightweight system that's simple and easy to afford. IBM ThinkPad R series notebooks are the newest addition to the most award-winning family of notebooks. Developed to share options - including the ThinkPad Port Replicator - with ThinkPad X, T and A series notebooks, ThinkPad R series notebooks help make managing multiple systems easier. Integrated wireless technology on select ThinkPad R Series notebooks provides a wireless connection to an access point-equipped network. Or, create a wired connection using integrated modem or Ethernet. The IBM Embedded Security Subsystem on select ThinkPad R Series notebooks helps safeguard information by offering local data and communications encryption, and by protecting encryption keys in the integrated hardware, rather than in software or memory, which are more vulnerable. The new Ultrabay Plus modular bay allows you to easily swap and share optional Ultrabay 2000 devices. Plus, outfit the bay with the optional Ultrabay Plus Device Carrier and you can snap in options like the Ultrabay Plus Cradle for the WorkPad c500 Series or Ultrabay Plus Numeric Keypad for even more flexibility.
