The Lenovo ThinkPad T440s is one of the best business laptops that you can buy. It has a strong build quality, serious styling, but most importantly, good speed, an excellent keyboard, and plenty of features. However, there is also a T440 (non ‘s’) model available, too. This is more of a low-cost option and we’ve outlined the differences between the two models below, just to make it a little easier for you to device which one to buy.
You can upgrade your IBM Lenovo T440 Laptop to up to a maximum memory capacity of 12GB Memory. How many total memory slots to install memory? The Laptop has 1 Slot to install memory, already with 4GB standard memory installed. In addition to two USB 3.0 ports, there's an SD card slot, Ethernet and VGA. Storage options are big and functional as well, with the option of either a 512GB or 1TB SSD. The T440 can also get up.
Processor speed: The ThinkPad T440 is available in a slower speed than the ThinkPad T440s. While both laptops are available with Intel Core i5-4300U and Intel Core i7-4600U processors, the T440 can also be bought with a slower Core i5-4200U processor.
Graphics: Both use Intel HD 4400 graphics that are built in to the processor.
RAM: Both the ThinkPad T440 and the ThinkPad T440s support up to 12GB of RAM. One memory slot can house up to an 8GB module, and there is also 4GB soldered onto the motherboard. The low end T440 doesn’t have on-board memory, relying solely on the memory slot.
Storage: Both the ThinkPad T440 and the ThinkPad T440s are available with a selection of hard drives and solid state drive options. Hard drives of 500GB (7200rpm) and 1TB (5400rpm) capacities are only available on the low-cost models, while a solid state drive up to 512GB can be selected in the most expensive models. The T440s also features hybrid storage in which the hard drive is aided by a 16GB mSATA solid state cache drive.
