The X250, though, inherits many of its predecessor's design traits and improves on them. It has two batteries that can combine to offer up to 20 hours of battery life, an improvement from the 17 hours of battery life for the X240. At 1.3 kilograms and 20.3 millimeters thick, the X250 is also lighter and thinner than the X240.
The X250 supports up to 512GB of SSD storage or 1TB of hard drive storage. The laptop also supports up to 8GB of DDR3 DRAM and has a 720p webcam. Wireless connectivity options include 4G LTE and Wi-Fi.
The ThinkPad X250 will ship next month starting at $1,149.
Lenovo's mainstream ThinkPad T450 and T450S laptops succeed the popular T440 and T440S laptops, which shipped in 2013. The T440S is now SSD-only, so a hard drive option isn't available, according to Lenovo's specifications. The T450S also has a two-battery design, much like the X250, and offers up to 17 hours of battery life with an optional second battery.
The T450S is 21 millimeters thick, which is big compared to comparable business laptops like the Spectre from Hewlett-Packard and XPS from Dell. The laptop supports up to 512GB of SSD storage and 12GB of DDR3 DRAM. It also has a mini-DisplayPort and an old-school VGA port, which is one reason why it may be so thick. Users can select 720p, full HD or touch screens.
Specifications for the T450 weren't available. The T450 starts at $849, and the T450S starts at $1,099. The laptops will ship next month.
Other ThinkPads with Broadwell chips that will become available next month include the T550, which starts at $999, and the E450 and E550 models, which start at $599.
