Reviews for the Lenovo Thinkpad T400
Source: Pricemo

Almost 10 hours of runtime with the extended battery easily puts this laptop into the all-day computing section. System performance with the Intel T9400 processor & ATI 3470 graphics was great, handling everything they threw at it, even some video games. The T400 is not without its flaws though, having a decent amount of keyboard flex as well as a keyboard light that blinds you. Even with its flaws, with a beginning price under $1,000 this laptop easily outperforms any other pc in its section.

While the Lenovo ThinkPad T400 isn’t exactly hip or something you’ll choose to win looks at a coffee shop, it is certainly practical and a laptop that is built to last. If you’re heading into a professional school such as law, business or medicine it might also fit the scene better there than say a bright blue colored Dell or Sony. Reliability and durability should certainly be a major factor in purchasing a laptop, and the ThinkPad T400 meets that requirement. The 14-inch screen size is a sweet spot for a balance between portability and having enough screen real estate to be productive. There is a lot of room to configure the T400 to your needs and budget at Lenovo.com so take advantage of that, and also take advantage of the fact Lenovo offers a student discount to many colleges that can save you 5% or so off the cost of any ThinkPad.

The high brightness display option on the updated T400 looks excellent and doesn’t take a huge bite out of your battery under normal activities. With most high brightness screens the power consumption is high even at lower brightness settings and what we found with the T400 is the impact on the battery is minimal at worst. On the 6-cell battery we managed 5 hours and 58 minutes of battery life, right on the mark with the previous T400 that used hybrid graphics. The updated keyboard support is my favorite change, knowing that Lenovo listened to feedback from users and improved the design. Overall, if you are in the market for a business notebook that is usable in direct sunlight, the T400 with the high nit screen option is the way to go.

Lenovo has presented a worthy successor to the T61 series with the T400. Every piece of the hardware, from the processor to the RAM to the HDD, was a solid choice by Lenovo and performed well under our testing. The battery life was excellent, in part thanks to unique features like Switchable Graphics, which let you switch between integrated graphics and the dedicated 256MB GPU at will. The brightly lit WXGA+ display was easy on the eyes and there were just enough peripherals (fingerprint reader, webcam, keyboard light) to keep us interested. Further, it was portable enough that we didn’t think twice about carrying it all over the office. Overall the computer was a great worker and did everything we asked, even if it didn’t drop our jaw with anything too astounding.

The $1,549 Lenovo ThinkPad T400, when bundled with its nine-cell battery, isn't the lightest 14.1-inch notebook we've tested, but it is one of the most powerful and longest lasting machines in its class. The switchable graphics, blazing fast processor, and Centrino 2 chipset allow users to have the best of both worlds: a highly-portable system that offers desktop-worthy performance while lasting well over 6 hours.

Nothing epitomizes classic more than a ThinkPad. Lenovo is the one laptop maker that would be castigated for changing its flagship brand's color scheme to something other than black. The ThinkPad T400 ($1,580 direct) is the culmination of years of building on a solid foundation, including nothing but the best parts, features, and materials in its ho-hum chassis. Lenovo's T-Series has once again set the bar for business laptops with up-to-date performance parts and a new Centrino 2 feature named Switchable Graphics.

The Lenovo ThinkPad T400 proved to be an exceptional 14" business notebook, giving almost unheard-of battery performance under modest running conditions. Nearly 10 hours of runtime with the extended battery easily puts this notebook into the all-day computing category. System performance with the Intel T9400 processor and ATI 3470 graphics was great, handling everything we threw at it, even some video games. The T400 is not without its flaws though, having a decent amount of keyboard flex and a keyboard light that blinds you. Even with its flaws, with a starting price under $1,000 this notebook easily outperforms any other computer in its category.

Comment
ATI Mobility Radeon HD 3470: Faster clocked HD 3450 and successor of the HD 2400 XT but with DirectX 10.1 and due to the new 55nm process, higher clockspeeds. Avivo HD video functions allow the decoding of HD videos.
Only some 3D games with very low demands are playable with these cards.
» Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.
Intel Core 2 Duo: This is the Core Duo and Core Solo successor with a longer pipeline and 5-20% more speed without more power consumption. As an addition to the Core Duo design there exists a fourth decoder, an amplified SSE-unit and an additional arithmetical logical unit (ALU).
The Core 2 Duo for laptops is identical to the desktop Core 2 Duo processors but the notebook-processors work with lower voltages (0.95 to 1188 Volt) and a lower Frontside bus clock (1066 vs 667 MHz). The performance of equally clocked notebooks is 20-25% lower than Desktop PCs because of the lower Frontside bus clock and the slower hard disks.
P8600:
Fast but still not overpriced dual core CPU. For most games and multimedia applications sufficient and due to the 25W TDP even for smaller notebooks useable.

14 inch display size represents a middle ground between the small subnotebook formats and the screens of the standard 15 inch laptops.
The reason for the popularity of mid-sized displays is that this size is reasonably easy on the eyes, provides good resolutions with usable detail sizes, yet does not consume too much power and the devices can still be reasonably compact.
In the past, 14-inch devices were very rare, but now they are the standard for laptops after the 15-inchers.
