Lenovo Thinkpad X220 I7-2640M
The ThinkPad X220 is available with two different anti-glare LED displays. The previously mentioned HD Premium IPS display and a "conventional" TN display. Both have a resolution of 1366x768 pixels and a screen diagonal of 12.5 inches with a 16:9 ratio. The IPS display has 300 nits and great viewing angles, whereas the TN screen (not tested) delivers standard performance.

The panel of the X220 is produced by LG Philips and offers a maximum brightness of 265 cd/m². We calculated a great illumination of 93% with an additional 8 points (at which we measured values ranging from 246 cd/m² to 262 cd/m²). The brightness level can be set at 15 different levels which starts from 4 cd/m² and goes up to 148 cd/m². From this level (level 13), the user can increase the brightness up to the maximum, which is however, just like in the ThinkPad W520, not the brightness level promised by Lenovo (300 nits).
The ThinkPad X220 is equipped with processors from Intel”s latest generation: Sandy Bridge. In comparison to their predecessors, the new CPUs deliver quite a bit more performance, and the mobile Intel QM67 chipset in the laptop can use up to two 2 slots which can hold up to 8 GB. Our test model came equipped with a single 4 GB RAM module, leaving one slot open for an easy upgrade. Adding another 4 GB RAM module is a piece of cake and is also worth recommending because this will allow the laptop to use the RAM modules in "Dual-Channel" mode.
The laptop can be equipped with a variety of regular processors (just like theThinkPad X201), which, unlike their "Low Voltage" and "Ultra Low Voltage" counterparts, deliver more performance. The offered Core i3, Core i5 and Core i7models cover a wide performance spectrum (i3 models are installed in the X220i); sadly, quad-core CPUs are not available for this model.
Our test model came with an Intel Core i5-2520M CPU which has a clock frequency of 2.5 GHz (Turbo Boost can increase the clock speed up to 3.2 GHz). Of course, this CPU also has "Hyperthreading" which allows it to generate two virtual cores (one for each real core), and thus, process up to 4 threads simultaneously. The slightly high "Thermal Design Power" (TDP) of 35 W is acceptable as this includes the power usage of the integrated graphic chip and the memory controller.
The graphic performance of the laptop is limited to the power of the integrated Intel HD Graphics 3000. This chip delivers enough performance for most tasks. Dedicated graphic card or other professional graphic solutions are not offered for this model as the laptop lacks the space for them, and even if it had such space, such systems would definitely make the temperature emissions shoot up.
The performance delivered by the small notebook is quite respectable. The CPU alone scored 5082 and 10767 points in the Cinebench R10 benchmark (single/multi), and more than 667 seconds in the superPi 32M calcuations, as well as up to 528 seconds in the wPrime200 1024m. All-in-all, this CPU ranks well at number 31 in ourin-depth CPU benchmark list.
As mentioned before, the graphic performance delivered by the notebook is insufficient for gaming or calculating 3D models. This statement is further supported by scores of 1678 points in the 3D Mark Vantage benchmark and 5135 points in the Cinebench R10 OpenGL Shading benchmark. This performance will not suffice for a high level of details or effects in games. Thankfully, full HD videos play fluidly even at low GPU clock speeds (maximum battery life), thanks to the DXVA-ready player. Intel”s HD 3000 graphics deal with flash videos without a problem too.
A second RAM module increased the performance of the graphic unit in the benchmark by 10-30% (a significant increase). This increase was mostly thanks to the activated "Dual-Channel" mode (the big RAM storage of 8 GB contributed much less to the increase). This mode improves memory efficiency and thus raises the graphic performance.

Games Verdict
The native display resolution of (1366x768) and low quality settings allowed games such as Racedriver, Sims 3 and Starcraft 2 to run well. With this configuration, the frame rates always lie in the green region and the picture is always fluid. Lower resolutions can further increase the frame rates, but doing so will make the games boring. Higher quality settings will lead to more stutters. A second RAM module might improve performance in this case (not tested).

Noise Emissions
THe loudness of the ThinkPad X220 varies depending on the BIOS version. We used BIOS 1.11 for our measurements. With this version, the cooler fan acted very conservatively, like the fans of the older ThinkPad models. We measured noise emissions between 28.6 dB(A) to a maximum of 38 dB(A) which are very good.
The quiet motor noise of the Hitachi hard disk dominates the noise scenery when the fan switches off. When the hard disk switches off, the laptop runs completely silently for a while. The use of a SSD can optimize the noise emissions further.
It is possible that the manufacturer changed the cooler fan settings due to the throttling issue in later BIOS versions. We used version 1.15 for a short while and we notice that the cooler fan ran a lot more and that throttling was still an issue. TPFancontrol showed that the cooler fan stayed at level 3 (around 34 dB(A)) most of the time. The cooler fan turns down only when the laptop is completely idle. Otherwise, the user just has to deal with a constant 34 dB(A) fan emission. The TPFancontrol tool proves useful in this case, as it offers a variety of levels at which the cooler fan can be run.
Thankfully, Lenovo has released BIOS version 1.16 which returns to the original cooler fan behavior. In office use or while surfing on the internet, the laptop cooler fan is very quiet at level 1 which is barely audible. A sudden increase or decrease of the fan speed or high noise emissions were not noticeable in our test.

Temperature
The case can reach a maximum of 39.7 to 43.2 °C under load. This is a noticeable increase in temperature but it will not be a problem as usually 3D calculations or rendering are not done with notebook on the lap. During normal use the temperature is around 10 °C lower at a maximum of 28.5 to 31.2 °C.
Speakers
The quality of the integrated speakers is standard as in most notebooks. There are too many highs, very few middles and little bass which means that the sound output will not make music enthusiasts jump with joy. Head phones or USB speakers should be included for mobile use if the user wishes a decent sound output.
The different battery models available for the X220 are guaranteed to give the user a great degree of flexibility. The small 3-cell battery with a 28 Wh capacity (0A36281) is the lightest of all the models. The 6-cell battery with a 63 Wh capacity (0A36282 -in our delivery), offers a good compromise between battery life and weight. Longer run times are possible with the 9-cell battery (0A36283 - capacity of 100 Wh) which when combined with the docking 6-cell battery (0A36280 - capacity of 64 Wh) should deliver the maximum 23 hours run time (according to Lenovo”s webpage).
The power usage (measured from the power adapter) ranged between 5.7 to 65.1 W. The ThinkPad X220”s frugal power consumption is a great basis for long run times. Does the battery make the best of this design?
