Graphics, Storage, Battery and Decision

ULV (ultra depression voltage) Broadwell variants are aircraft with Hd 5500 and not Hd 6000 graphics cores. Based on benchmarks from effectually the web though, the HD 6000's performance advantage is minimal despite its doubling up of execution units. Both add back up for 4K UHD (DisplayPort) and DirectX eleven.ii.

The HD 5500 should perform roughly 20 percent faster than Haswell's Hard disk drive 4400. It besides majorly outperforms the Hard disk drive 5300 institute on lower ability Cadre 1000 processors.

Productivity is fine and skilful, but what if you want to have a little fun too? With Intel HD 5500 integrated graphics, don't expect to take *too* much fun. I'm partly kidding, of class. We're living in a low-fi gaming renaissance and the Hard disk drive 5500 can handle many enjoyable titles. Merely don't expect to terminate up Batman: Arkham Knight while waiting at the airport terminal.

Existence equipped with an i7 and Broadwell may help the T450s edge out some other ULV ultrabooks with Intel graphics. Notwithstanding, you'll still be confined to low resolutions and generally older, simpler titles. Team Fortress 2 (2007), DOTA2 (2013) and Path of Exile (2013) actually ran well at 720p with depression to medium graphics settings. Bioshock Infinite (2013) and Tomb Raider (2013) pushed the HD 5500's limits fifty-fifty at their lowest possible settings. Frame rates during gameplay oftentimes dipped into the teens, making them just marginally playable.

Memory

Officially, the T450s can handle up to 20GB of retention. The system board integrates 4GB of non-removeable DDR3L plus a unmarried user-upgradable So-DIMM slot. This slot can accommodates up to 16GB of DDR3L (PC3-12800). Every bit all manufacturers attempt, Lenovo hopes to lure y'all into expensive upgrades. Adding a 4GB module (8GB full) at checkout volition set yous back effectually $fourscore. Meanwhile, adding 8GB (12GB total) and 16GB (20GB total) cost a whopping $170 and $430, respectively. That's roughly a 400-percent markup over doing it yourself! Value minded enthusiasts may want to consider the DIY approach.

Storage

The base model ships with 500GB of mechanical storage but nearly anyone reading this should absolutely want an SSD. Lenovo offers solid country options ranging from 128GB to 512GB. Optionally, Lenovo offers OPAL-compliant SSDs (i.eastward. self encrypting drives) to meet the needs of corporate customers. Once once more, manufactory upgrades are prohibitively priced: 128GB for $130 and 512GB for $430. Cost conscious enthusiasts can easily install their ain SSD to salvage 50-75 percentage over Lenovo-installed upgrades.

Our review unit of measurement shipped with a 128GB Toshiba SSD (THNSNJ128GCSU). It's unremarkable offering only does manage to postal service some solid numbers. Note that many manufacturers, Lenovo included, employ various models and vendors for storage interchangeably. Verbal storage performance characteristics may vary slightly from one unit to the next as a upshot.

Bated from traditional SATA options, the T450s includes one M.two slot keyed for storage devices. For $10 more, you can even add some other ane at purchase. For those unfamiliar with the One thousand.2 (formerly NGFF) specification, its slot and card variations can be confusing. Substantially though, the spec allows expansion cards (storage, network or otherwise) direct access to a diversity of system buses (e.g. PCI Limited, SATA, USB, DisplayPort) through a common interface. The standard has been growing in popularity among enthusiasts for calculation high-functioning flash storage and cache devices.

Although the T450s ships with multiple M.2 slots, Lenovo offers only a 16GB wink enshroud drive; however, owners may install their ain M.2 SSD if they wish. Physically, the T450s accommodates cards no larger than 2242 (i.e. 22mm wide, 42mm long) and the slot is keyed for storage. I have not seen the optional slot, only I would expect it to the be aforementioned.

Battery

Battery life is excellent. Even with its Intel Core i7 and stock 45Wh bombardment, the T450s lasted more than 7 hours in synthetic tests. In real life, where the system was allowed to idle, sleep and dim the display, it easily met my needs for an 8 hour work day. If yous suffer from battery anxiety, Lenovo also offers an optional 6-cell 72Wh pack which finer doubles the battery capacity to 96Wh. However, trade-offs are increased weight (+0.3lbs), increased price (+$140) and decreased portability (a sizeable hump is added to the lesser of the chassis).

How does the T450s achieve its long battery life? For one, Broadwell is exceptionally energy efficient, largely due to its significant die-compress from 22nm to 14nm. Secondly, there are really two batteries on the T450s: one is removable, ane is internal. Each 3-cell battery is rated at nearly 24Wh -- the two of them together is slightly more than many (but non all) ultrabooks in this weight class.

Lenovo's "Power Bridge" technology makes having two carve up batteries seamless. If the removeable bombardment is depleted or asunder, the internal bombardment instantly takes over. Equally a result, owners can hot bandy their dead battery for a fresh one at any time with no need to plug in nor interrupt their work. It'southward a niche feature, but i that veteran travelers and field professionals volition appreciate. For the tape, the power indicator in Windows also accurately reflects the batteries' combined status.

Display

There are 3 screen options, all of them 14-inch with a 16:9 aspect ratio: 1600x900 (matte TN), 1920x1080 (matte IPS) and 1920x1080 touch (sleeky IPS). Our T450s shipped with choice number two, the 1920x1080 IPS matte display. It's quite vivid (300 nits) with fantabulous viewing angles. Colors were rich and accurate, even when compared against a Dell UltraSharp U2713H.

Matte (anti-glare) is ideal for indoor settings but easily washes out in direct sunlight. Thanks to its strong backlight, the screen was just barely usable in direct midday sun. Of form, it fared much amend on cloudy days and in shady areas though.

Although no comparison to the immodestly named "Infinity Display" constitute on our recently reviewed Dell XPS xiii (2015), the T450s does boast its own thinner bezel than previous Thinkpad T generations. This reduction in bezel size too allows for a smaller overall footprint.

The brandish hinges open to a full 180-degrees, but equally many (only non all) Thinkpad T models have before it. The carbon fiber reinforced chapeau is quite rigid and won't have owners wincing every bit they open it from one corner with i hand. The hinge activeness is solid, smooth and tight. At that place were no signs of potential issues to come.

Keyboard and trackpad

Compared to other notebooks (specially ultrabooks), the T450s boasts a phenomenal keyboard. With some degree of confidence, I tin say this is the best membrane keyboard on any laptop -- aye, including other Thinkpads. The keys have a smashing tactile feel. They combine firm actuation strength with significant travel merely remain adequately quiet. It's perfect for banging out emails and documents on the go. LED backlighting with 2 levels of intensity can be toggled by pressing the FN and spacebar keys simultaneously. Additionally, the spill resistant keyboard (run across a demonstration) features a protective layer which channels liquid away from vital components and into drainage areas.

A common complaint with the prior Thinkpad T model (T440s) was the buttonless "clickpad". The lack of physical buttons meant users were at the mercy of tap zones and multi-finger gestures. While Thinkpad fans tend to be intolerant of changes like these, Lenovo's implementation of those features was an admitted failure so the backlash was deserved.

Well, the much maligned clickpad makes its return to the T450s. My promise to you though is this: Lenovo got information technology right this time. For one, the surface is superior to the T440s with its silky smooth, teflon-like feel. Mutual multi-touch gestures like right-clicking and scrolling by tapping or dragging two fingers (finally) works reliably. Pressing and depressing the clickpad no longer cause the mouse cursor to inadvertently motion around. Palm check works better. The T450s has the all-time buttonless trackpad I've used on whatever Windows laptop.

When Lenovo nixed mouse buttons on its UltraNav system, Thinkpad loyalists collectively scoffed. In response, Lenovo revived these buttons with T450s simply non without compromise: only the top-most buttons to a higher place the clickpad have returned. No, this won't placate Thinkpad diehards. Rather, information technology's an olive branch for trackpoint users (a.thou.a. arrow stick, nub, eraser head) who had difficulty determining where the "push button" zones were on the previous clickpad. By bringing back simply the top mouse buttons, touchpad users can still bask the largest possible tracking surface while trackpoint users become their buttons back. It'south pretty much a win-win, just only if you are willing to take a buttonless trackpad.

Conclusion

The Thinkpad T450s isn't all that different from nigh recent predecessors, merely information technology does bring some welcome updates to the series, namely Broadwell, a redesigned clickpad, 3 x USB ports and a smaller footprint. Additionally, it carries over many great features from previous generations like a CFP chapeau, IPS screen, durable 3.5 pound blueprint and amazing keyboard. It is very difficult to come up upward with annihilation negative to say about the T450s. It does then many things well.

In respect to its business organization-class peers, (east.thousand. HP Elitebook Page 1040, Dell Latitude 14) the T450s is also a all-time-in-class value. With its immense array of positive attributes, the T450s is a very recommendable notebook to any business professional.

For general consumers, its value is less articulate. When considering the base model, similarly specced ultrabooks (Broadwell, Intel Core i5, 14-inch) can exist had for slightly less. In many cases, the toll deviation is then little though (less than $100) that benefits in bombardment, ports, keyboard and durability over cheaper models may exist worth it. When factoring in older Haswell and 13-inch ultrabooks though, the T450s is quickly overshadowed by significantly cheaper alternatives. Additionally, Lenovo's expensive manufactory upgrades apace erode the T450s value confronting loftier-end consumer ultrabooks too.

Pros: Arguably the best Thinkpad T in recent years. Durable carbon fiber hat and inflexible magnesium-alloy chassis. Bright, accurately colored 1080p IPS display. Amazing keyboard, even by Thinkpad standards. Redesigned clickpad works flawlessly. vii hours or more battery life can be doubled with optional battery pack. Best-in-grade value for business organization professionals.

Cons: Factory upgrades are expensive. Questionable consumer value when considering older Haswell and 13 inch options with similar specs.
