Simultaneous to the T420, we also looked at a 15.6 inch model from the T520 range. Here, the only significant change in comparison to the T510 is also the hardware refresh with the new Sandy Bridge processors from Intel.

Our test device"s exact name is T520 4240-4CG. An Intel Core i5 2410M CPU supplies the adequate computing performance inside. Either an NVIDIA NVS 4200M graphics card or solely the Intel HD Graphics 3000 integrated in the processor takes care of pixel calculations (Optimus). A four gigabyte DDR3 main memory and a fast 500 GB hard disk with a revolution speed of 7200 rpm complete the configuration.

The T520"s immediate opponent is found in Dell"s Latitude E6520, which can be configured at most with an i7 and the NVS 4200M graphics card as well. Unlike Lenovo, Dell uses a new look. We hope to provide you with all details in this review.

In regards to design, we have had this case in review a few times before. Starting with the T500 over the T510 up to the latest T4x0 series, Lenovo couldn"t compel to make any surprising design modifications in the current T520, except for minor ones. Considered by itself, sticking to the tried and tested isn"t at all bad, but innovations don"t stop in case design. And compared to the competition, you would think that a high-priced laptop such as the T520 would, in a sense, deserve a complete metal case now, though.

Instead, Lenovo still sticks to the plastic look & feel. Nevertheless, the T520, practically dressed entirely in black has a certain air of elegance and the matt slightly roughened surfaces have a pleasant feel anyway.

Two USB 2.0 ports and the eSATA/USB 2.0 socket are located on the left edge"s center. In addition, there is an IEEE 1394 (FireWire) port in the front area. It is mainly used for fast data exchange between the computer and multimedia or other peripheral devices, for example video cameras. Both video interfaces, analog VGA and a digital display ports, are also placed on the left edge center. Thus, left-handed users are definitely disadvantaged depending on what"s in use.

It looks better on the right. There is a 4in1 cardreader, which supports SD, SDHC, SDXC and MMC formats, and an ExpressCard34 slot, which makes it possible to extend the T520"s functionality. The combo audio port, the optical drive, an RJ45 for connecting the laptop to the Ethernet and a Kensington Security slot follow towards the rear.

Apart from the Kensington Security lock for physical securing against theft, the T520 is also equipped with a fingerprint reader among other things. A splash water proof keyboard and a shock proof hard disk protect the system against data loss in case of the corresponding mishap.

Appropriate for a business device, Lenovo equips the T520 with a matt screen and thus meets the requirements placed on display workstations. Alike the predecessor, three alternatives are available, all in a 15.6 inch, 16:9 size and with a built-in antenna for a broadband modem. The potential buyer is spoilt for choice with HD, that is 1366x768, HD+, that is 1600x900 or FHD, that is 1920x1080 pixel resolutions.

The Thinkpad T520 is based on the QM57 chip set. It"s offered with a range of second generation Core i processors, called Sandy Bridge. The performance spectrum ranges from various Core i5 CPUs up to the Intel Core i7 2820QM quad core processor.

Our T520 test laptop is at the start with a Core i5 2410M CPU. It is a midrange dual core processor. It can process up to four threads at the same time due to Hyper Threading. Its base clock rate of 2.3 GHz can be increased to 2.6 GHz (2 cores loaded), respectively 2.9 GHz (1 core).

Our performance tests were all executed with the NVIDIA NVS 4200M, which has been installed in the fully equipped Thinkpad T520 at hand. For comparison, the same chip, with a lower clock rate, was used in the recently reviewed Dell Latitude E6420.

The business graphics card positions itself in the entry level range in terms of 3D performance. The NVS range is especially optimized for stability and business applications. The NVS 4200M also supports PureVideo HD (VP4) for decoding HD videos (H.264, VC1, MPEG-2, Full Spec Blu-Ray Decode). Monitors with a resolution of up to 2560x1600 pixels can be connected via the display port. One gigabyte of DDR3 RAM are tethered to the 64bit wide memory bus.

Let"s look at our Cinebench test results once more. But this time at the shading rate, which assess the graphics card"s OpenGL performance. Our test system can score 5355 points in the Cinebench R10 64 bit Shading Test. Thus, the T520 positions itself in the immediate vicinity of laptops with a GeForce GT 540M or even Radeon HD 6550M graphics card in our database. So, it exceeds the Latitude E6420 that reaches 4471 with the same, but lower clocked graphics card and weaker processor, with surprising clarity.

It looks different in the 3DMark tests. The E6420 and our T520 are on the same level throughout the tests. The graphics chip places itself in the range of a GeForce 320M, respectively GT 130M in the 3DMark06 test (1280x1024). Interestingly, even the incorporated Intel HD Graphics 3000 can come close to the 4000 point mark, depending on the test configuration.

Our T520 has really not been designed for CAD applications. A look at the SPEC Viewperf 11 benchmarks proves this. The T520 can again surpass the Latitude E6420 across the board, but the overall performance remains in the lower field of our database, just before the NVS 3100M. Graphics solutions from the Quadro FX or FirePro category supply a multiple of performance here.

The T520 doesn"t show any irregularities in use with low load and stays at a constant noise level of 32.5 dB(A). It can be perceived as a low pitched noise. The fan noise remains on an idle level for a long time when the load is increased, for example in 3D applications, only to turn up to 34.4 dB(A) later. A maximum noise level of a very audible 36.8 dB(A) can be reached.

We could do research on the internet for almost five hours via WiFi hotspot in brightness 12/15 and in energy savings profile in both practical tests. Movie entertainment ends after almost three hours in maximum brightness and "Video" profile.

The Thinkpad T520 thus represents a solid notebook with good application performance and, thanks to Optimus, good mobility qualities for business clients. It is definitely to be placed in the office field in view of performance. However, it"s not suitable for CAD applications despite the dedicated graphics card. But the Thinkpad W520 is designed for that and its review will follow shortly.

Today I am going to guide you through replacing the display of a Lenovo T520 Laptop. This particular laptop had some issues in that the display was humming in relation to screen brightness and had multiple dead LED"s.

At the time of this writing the replacement display is $50 US and is a LG LP156WH4 there are several displays that are compatible however we just went with the direct replacement.

There were 2 laptops that were turned back in on our last refresh that had some dead spots in the back light. As you can see by the picture the laptop on the left has been replaced, the laptop on the right is the one that I am going to replace the display in the video. I figured that as we had 2 out 15 that there are probably more people out there that are experiencing the same issue.
