Lenovo’s ThinkPad lineup needs almost no introduction, being one of the most well known business lineups around. The T series has been around for what seems like forever, and it is the premium lined aimed at the business and enterprise segments.  The lineup includes both 14 and 15-inch models, and today we have the ThinkPad T450s which is a 14-inch model. The “s” addendum designates that this is the slim version of the T450.

Lenovo calls this an Ultrabook, and although that definition has expanded over the years, the T450s is not your typical ultra-thin notebook. That is not always a bad thing either as we will see later in the review. The T series sits between the thin and light X series and the mobile workstation P series ThinkPads.

When discussing business notebooks, there are generally a few features added that are not available in your typical consumer grade notebook. These are going to be things like Smart Card readers, Intel’s vPro technology, docking connectors, Ethernet connectivity and a durable chassis. Lenovo offers all of this on even their slim model T450s, which is basically as thin as it can be to still include a RJ-45 Ethernet port.

Durability is something that business wants too, since these devices are going to be used as long as they can be before replacement. Lenovo includes a very strong magnesium chassis and uses carbon fibre on the lid with glass fibre used where the radios are to limit attenuation. The keyboard is spill-resistant, and the T450s has been tested against Mil-SPEC 810G testing on things like humidity, temperature, vibration, radiation, and both mechanical and temperature shock. Durability is of course something that we can’t test, but having passed these standardized tests should mean that the T450s will perform well for employees over the long haul.

Since this is classified as an Ultrabook, it should be no surprise then that it is powered by the Intel Core U series chips, and Lenovo offers the Core i5-5200U, i5-5300U, and i7-5600U models. Memory includes 4 GB of RAM soldered onto the motherboard and one DIMM slot which can handle up to 16 GB of DDR3L-1600 for a total of 20 GB available on this notebook. Display options are 1600x900, or 1920x1080 with either a matte coating or optional touch. A full list of the specifications are below.

The ThinkPad T450s is not yet offered with Windows 10, so this review was done with Windows 8.1 Pro installed. Lenovo has some interesting technology available in the T450s including their Power Bridge technology. This is a very smart setup and includes a 23 Wh battery integrated into the front of the laptop, and a removable battery at the rear. The default option is another 23 Wh battery, but Lenovo also offers both 48 Wh and 72 Wh battery options for the rear model as well, so the T450s can be used with a massive 95 Wh of capacity in one charge. The coolest part of the Power Bridge though is that the rear battery is discharged first, and it can be swapped out with the laptop still running so if you have a couple of extra batteries you would be able to work offline for a very long time.

Storage offerings start with mechanical drives, but you can of course opt for solid state storage as well which is always going to be a better experience. Lenovo also offers Opal2 offerings which is going to be popular with a lot of businesses.

The Thinkpad T450s is aimed right at the heart of business, with plenty of features that businesses look for, a well built chassis, and MIL-Spec tested components. Though it is not as thin and light as a lot of Ultrabooks, including Lenovo’s own ThinkPad X1 Carbon, there is a lot of laptop here which should be interesting to anyone looking for a 14-inch laptop. Let’s start with the design.

    Hang on, it states in Intel's ARK platform the the 5300U can support only up to 16GB of RAM. Where does this strange 20GB number come from? Though I would recommend adding another module regardless to gian the benefit of dual channel memory, I don't much thing 20GB of RAM in this machine is addressable.

    It impossible to achieve 16GB RAM; if the first slot is filled with soldered 4GB stick! There is no 12GB stick! You an upgrade to 12GB or 20GB!

    When I saw only "Optional 1920x1080 IPS" as the better option for the screen, I stopped reading.
    I am typing this on a 10year old T43p with 1600x1200 UXGA (133DPI) and would expect a high-DPI matte "Retina" screen for the better an option, best in 4:3 form factor.

    I notice you say the maximum memory is 20Gb, I guess 4Gb on board plus a 16Gb in the second slot. However on their website Lenovo state the maximum memory as 12Gb. I'm confused, are they correct or you, did you try it?
  • Actuallykeith - Friday, September 25, 2015 - link

    Hi, looked more closely at their US site and although the spec says 12Gb max, the config allows 20Gb, so I've answered my own question. Cheers

    Just purchase a T450 with 8GB. It has a 4GB stick soldered in the first slot and a 4GB in the second slot beside it, why not just have on 8Gb soldered in and forget about dualism. I have to now wait a few years for the 16GB stick which is approximately $200; to fall. If you buy the 8GB stick for around $50; you only get 4 extra GBs. Lenovo is not doing me any favorites with their idiotic practice in matching RAM size!

    Thanks for the review, which is very informative.

    I have a question. Can the docking port on the bottom still mate with the docking station when an upgraded taller battery is installed?
  • Lad - Thursday, August 19, 2021 - link

    My ThinkPad T450 is not clocking the 17 to 21 hours of battery life. I recently reinstall everything and my dual batteries both can make upto 5 hrs of fully charged. What do I need to do so as to get my batteries efficient to its powerhouse of 21 hours.

    Help please, if you know the twikings of the drivers or what ....
