The new ThinkPad X61 and X61s notebooks also have a new input/output disablement feature for tighter security, and as much as 12 hours of battery life with an eight-cell standard battery and optional extended life battery. Along with the new ultraportables, Lenovo also introduced the X61 Tablet PC and the Lenovo 3000 V200 notebook, which features a built-in optical drive and multimedia features.
The integrated antennas on the ThinkPad X61 and X61s notebooks improve broadband wireless data transmissions by more than 30% while increasing the range over previous models, the company said. The notebooks also have several connectivity options such as 802.11n Wi-Fi and Bluetooth.
The X61s has more than 12 hours of operation with an eight-cell standard battery and optional extended life battery. The X61 and X61 Tablet get up to 11 and 10 hours of operation, respectively. The PCs include power management software for disabling select functions in order to extend battery life up to 15%.
Security features in the ThinkPad X Series ultraportables include new 32-byte hard-drive password protection and the ability to disable any port on the outside of the system, from a CD/DVD drive to a USB or Firewire port. The PCs also have an integrated fingerprint reader.
The X61 Tablet, powered by an Intel Core 2 Duo microprocessor, has a SXGA+ screen that's readable outdoors, even in direct sunlight, Lenovo said. SXGA+, which stands for super extended graphics array, is a display standard used in 14- and 15-inch laptop LCD screens with a resolution of 1400 x 1050 pixels.
The ThinkPad X61 and X61s notebooks and X61 Tablet PC start at $1,484, $1,474, and $1,779, respectively. The Lenovo 3000 V200 starts at $1,199.
Besides introducing new PCs, Lenovo also updated its ThinkPad and Lenovo 3000 notebook line with the ThinkPad T61 and R61 15.4-inch widescreen notebooks, and the Lenovo 3000 N200 14-inch widescreen notebook. The T61 and R61 start at $1,215 and $1,145, respectively. The N200 starts at $949.
The new products are scheduled for release in June.
Earlier this week, Lenovo, in a partnership with IBM, launched a 24-hour PC help service for small businesses and consumers. The new Experts Live service covers areas traditionally beyond the scope of a computer's warranty such as operating system and application support, system tune-up, and networking assistance.
