Review Lenovo Thinkpad T61p Notebook

p as in Performance... Soon after the Thinkpad T61 series also the T61p serious was launched. They are in general based on T61 models, but trimmed for performance, so, that they meet even higher performance demands (NVIDIA Quadro FX 570M). These notebooks, which are especially liked by designers and 3D design engineers, are of course also equipped with a proper display, in our case with a WUXGA panel with a resolution of 1920x1200 pixels.

IBM/Lenovo Thinkpad T61p

Case

As already mentioned the T61p is based on the already reviewed T61. So, also the cases do not much differ from each other. So, the criterion case is more or less the same as in the review of the Thinkpad T61. However, some changes exist, but, they are not so important for the user. E.g., the speakers are now located at the top side of the keyboard.

An important part of the Thinkpad identity is its black case with cheap looking plastics flavour. This might sound bitter, but handling  this notebook quickly puts this impression into perspective.

Generally this compact 15 inch notebook's robustness is excellent. A waste of time to try to deform the Thinkpad T61 under pressure. However, if you, legitimately for a notebook of this class, scrutinize the case, you'll still find some parts with smaller weaknesses.

E.g., the plastic cover next to the Thinkvantage buttons yields and silently creaks somewhat under pressure. Similarly, the same can be observed for the region of the optical drive at the bottom side of the notebook. Especially, the weakness at the UltraBay slot is one, which already exists since some Thinkpad generations.

Let's finally stop complaining. The T61's workmanship is as expected very good and also the stability of the case is first class. This is supported by a metal frame inside the notebook and magnesium parts at its surfaces.

The display of the T61 is especially strengthened, and so, it scores better now than the also very robust T60. A special comb construction under the displays cover further increases flexural rigidity and pressure resistance.

The display stands out because of the strengthened molding at its edges, known as ClamShell design was further reduced. While  it exceeded the display frame by about 1 centimeter at the top part of the R50, now only a gentle rise is apparent. So, the look was clearly improved and while it is still  sufficient to guarantee a nearly seamlessly closed display. So, dust and dirt particles cannot accumulate in the inter space.

Also the look of the hinges were slightly adapted. Their height got smaller, but in turn their width increased. The edgy and massive form still stayed the same. Still the metal hinges are capable to absolutely securely keep the display's position.

The same is true for the ramshorn hook, which secures the closed display and is easy to handle by a switch placed at the front edge of the display.

The provided interfaces and their order is typical Thinkpad. In order to be able to also use especially huge high-capacity batteries with this notebook, the battery was again located at the T61's backside. So, batteries with higher capacity can exceed the case and so provide more cells. This is a special aspect for the T61, but we'll discuss this later.

Regarding order of the interfaces the T61p differs a little bit from the 14 inch T61. The audio ports are at the left side, instead of unhandily at the front side. And also an additional card reader is provided there.

Some more words to the security aspect, which is a special consideration of the Thinkpad series: The T61  provides comprehensive security features, e.g., a shock protection for the hard disk, a fingerprint reader and a TPM chip including compatible software.

Input Devices

Alike the case also the touch pad / track point combination is the same as the one of  T61 notebooks.

Among the input devices you'll detect a well-known Thinkpad friend - a spacious, red track point in the middle of a jet-black keyboard. Themed: "Red track point outside, quality inside", all the input devices can be assessed.

The keyboard is clearly structured and, so, very user-friendly. The only exception is the FN pad, which is located left besides the Ctrl key, a somewhat unusual place for those unfamiliar with Thinkpad keyboards.

Typing has a soft stop, yet a clear action point, and a sufficient travel. Furthermore, the keyboard stays quiet, even during fast and forceful typing. Speaking from my own experience, I can conform that this persists even over years of intensive use, if the quality of the parts stayed the same.

Because of the slim wide-screen format of this notebook, the touch pad had to be placed relatively near the front edge, which somewhat complicated using the pad and its buttons on the lap. Although, the pad is very user-friendly, besides its small dimensions, we would recommend to use the trackpoint instead, in this situation (actually always ... ;-)).

Even, if there is some time of adaption needed, in the long term there is no doubt that the trackpoint clearly is the better mouse replacement, because it makes quick navigation without repositioning possible. It's even possible to play games with the trackpoint...

Following hotkeys are provided by the Thinkpad T61: above the keyboard some small buttons for controlling the volume and deactivating the sound, furthermore, the blue ThinkVantage button, which can be used to invoke a menu with a variety of Lenovo specific tools. This menu, e.g., provides help with networking, data protection and a number of configuration options. If you press this button during the boot process, the recovery system, which can be used to backup and restore data, will be launched.

Display

Color Diagram
Lenovo Thinkpad T61p display measurement

The reviewed Thinkpad T61p came with the top of the available displays, a 1920x1200 pixels WUXGA display with (certainly) matt and non-reflecting surface.

Alternative to this high resolution display also a 14 inch version with SXGA+ Panel (1400x1050) is offered. Other 15 inch display versions are at the time of writing obviously not available.

In the middle of the lower part a maximum brightness of 182.9 cd/m² was measured. This would be a good value, but, the brightness clearly diminishes to the sides and to the top. So, the average brightness of 159.6 cd/m² is acceptable and the illumination of 79.6% moderate.

The minimum brightness of 0.3 cd/m² gives together with the maximum measured brightness of 182.9 cd/m² a maximum contrast ratio of very good 610:1. No anomalies were detected by the Pixperan test of legibility and scroll tests.

Operation Outdoors
Lenovo Thinkpad T61p Outdoor

Outdoors you'll clearly recognize that the display's brightness is a little too low. 20-30 cd/m² more would have made it more fit for outdoor operation. In total it is fit for outdoor usage, but does not convince outdoors, because the rather dark display tires the eyes.

The FlexView panels, which were often offered and also bought in older -p series, are in the meanwhile consigned to history. Also the WUXGA display of Lenovo Thinkpad T61p rates to some degree acceptable in this aspect. The horizontal viewing angles are alright and also vertically, the area of operation is sufficient, but, at acute angles you'll face vitiations.

Performance

In order to make the Lenovo Thinkpad T61p also fit for demanding 3D applications, a NVIDIA Quadro FX 570M with 256MB VRAM is used beside an up-to-date Core 2 Duo processor.

The 3D Mark benchmark results as well as the refresh rates observed with various current games in practice are very good. The Quadro FX 570M is similar powerful than a Geforce 8600M GT, so, the T61p reaches a performance level of an Asus G1S and a Macbook Pro, which are both equipped with GDDR3 RAM.

As we already saw in many of our reviews, the GDDR3 memories make it actually possible that the Geforce 8600M GT rates very good in all performance tests. The Quadro FX 350M, which is actually based on a 8600M, can also reach the level of up-to-date gaming notebooks, because it also utilizes GDDR3 memory.

So, at the time of writing, the Lenovo Thinkpad T61p provides the most powerful video solution available for 15“ notebooks. If you demand even more, you'll need to choose a 17“ desktop replacement.

CPU and memory are also very good: Core 2 Duo CPU T7500 with 2.2 GHz 4MB L2 Cache and 800 MHz Frontsidebus, 2GB main memory, and a fast 100GB hard disk with 7200 revs/min.

In total it is a powerful office notebook, also sufficiently powerful for 3D demands.

Both games are also with highest resolution playable, but with limitations.

Emissions

Loudness

Of course the powerful 15 inch notebook must also be cooled down. Still, in idle mode with minimum energy settings the fan is nearly completely off and  the notebook comfortably quiet, if there would not be the noise of the hard disk. The noise of the Lenovo T61p is dominated by the hard disk. Only when the performance demand increases the fan gets more evident, but, still not annoying. After its work is done, if quickly returns to lower speed. Annoying: In battery mode with profile "high performance" a high-frequency noise is audible. If you change to 'minimum energy demand or 'balanced' it disappears again.

Temperature

Also the surface temperature of the T61p stays alright. Neither at the top side nor at the bottom side the temperature increase is disturbing. A maximum of 40°C can easily be stand.

Upper side

Speakers

The 15 inch case differs to the 14 inch version here. The speakers of the 15 inch wide-screen screen notebook are left and right above the keyboard and no longer at the sides.

The sound is alike the one of the T61 clear. Because there is no sub woofer, the basses are weak, but, this is not important for a professional business notebook.

The audio output of the analog stereo 3.5mm connector was during our test without anomalies and the provided sound was clear.

Battery Runtime

Also the battery differs to the one of the T61: The standard battery is a 5200 mAh battery, so, also the runtime with base equipment is alright. A further positive aspect is that the battery does not exceed the case, but, is flush with the back edge.

The runtime ranges in the reviewed version from a minimum of slightly above one hour to a maximum of about 3.5 hours.

Furthermore, it is possible to equip the T61p with a supplement battery, quite like all Thinkpads with ultrabay drive, and, so increase the runtime.

Verdict

Lenovo Thinkpad T61p
Lenovo Thinkpad T61p

The T61p fulfills the expectation of the T-p series to be more powerful and in general "better" than standard T notebooks. The T61p has all the advantages of the T61 which are a among others a robust magnesium case and excellent user-friendly input devices.

The display is the better choice. The WUXGA display with a resolution of 1920x1200 pixels provides maximum overview on the 15 inch display. A fineness of 147dpi is finest possible today.

Brightness and illumination are rather average, and could especially be better for outdoor usage. Indoors they are alright.

The second important difference to the T61 series is of course the provided performance of the notebook. The NVIDIA Geforce Quadro FX 570M is equally powerful than the fast Geforce 8600M GT series in the benchmark test, thanks to GDDR3 memory.

The emissions are also depending on usage and demand alright. The  built-in 7200 revs/min hard disk is permanently audible and, so, a little too loud. The surface temperatures stays all the time alright.

Regarding battery runtime, it seems that Lenovo tried to avoid another disgrace. In contrary to the T61 series the Thinkpad T61p is equipped with a 5200 mAh battery by default, which is also completely integrated in the case.

It provides a runtime of up to 3.5 hours. Furthermore, the additional use of an ultrabay supplement battery is also possible.

 

Many thank to the company Planet Notebook which kindly provided us with the reviewed notebook. You can configure and also buy this notebook here.
