IBM ThinkPad T40 notebooks are a new benchmark of computing performance, battery life and mobility. Work unplugged longer by combining the ThinkPad T40 high-capacity battery with the optional ThinkPad Ultrabay Slim Li polymer battery for all-day computing (up to 9.5 hours).The unique IBM Embedded Security Subsystem, an IBM ThinkVantage Technology, is available on select models. This hardware and software solution can help safeguard data with encryption to virtually lock private information. IBM Rapid Restore PC, another IBM ThinkVantage Technology, is preloaded - giving you the power of a one-button recover and restore solution to save time and frustration. The ThinkPad T40 notebooks include the IBM UltraConnect Antenna built into the cover. This can improve signal reception whether you choose models with integrated IBM 11a/b Wi-Fi wireless, Cisco Aironet Wireless 802.11b or when used with compatible options on wireless-upgradeable models.
