Battery Dell Vostro 1510

The test device's full name is T420 4236-NGG.(HP 8510w battery ) Inside an Intel Core i7 2620M CPU does its job. The incorporated graphics chip, Intel HD Graphics 3000, is exclusively available for video output in our test model. This configuration is supported by a four gigabyte DDR3 main memory and a fast 500 GB hard disk with a revolution speed of 7200 rpm. Aside from various Core i processors, ( Battery Dell Inspiron 6400 ) the T420 is also available with a dedicated NVIDIA NVS 4200M graphics card and Optimus technology – at least in the USA. Consequently, the rating of performance contingent parts is dependent on the real configuration and can't necessarily be applied to other models.

The Thinkpad T420 can practically be seen as an immediate opponent of the basically similarly configurable Latitude E6420 from Dell.( Dell Vostro 1520 battery ) While Dell has opted for a completely new design, ( VGP-BPS13B/B battery ) Lenovo contrarily sticks to the tested and tried Thinkpad design for the Thinkpad T420. We will show to what extent both vying notebooks differ in detail.

Case

14 or 15 inch, the looks have been maintainedAt first glance, ( Battery Dell Vostro 1510 ) The T420 doesn't seem to differ from the T410 much. But this is deceptive. For one thing, the display's diagonal has slightly shrunk from 14.1 inches to 14 inches. The same applies for the laptop's height and width, (Battery Sony VGP-BPS13/B ) whereas the depth has interestingly gained a bit. The measurements for comparison: 30.5x340.5x233mm for the T420 and 32x336x239 for the T410.

Albeit, as we will see in a moment, quite a few changes have been made on connectivity, Lenovo sticks to the proven, light clamshell design. No modifications can be found in color or material choice, either. ( Dell Inspiron 1525 Battery ) The almost completely black case has been made from plastic. The haptics correspond to the choice of materials. However, the matt and slightly roughened surfaces don't feel unpleasant.

The case's stability is basically satisfying. But it still shows the same weaknesses known from the T400. So, ( Dell Inspiron 1420 battery ) in the Ultra Bay slot's area and on the plastic cover above the keyboard. The case can yield somewhat and creak under selective pressure.

The display components stand up well to our warp and pressure tests.(Battery Inspiron 1520 ) It hardly bends when the case is lifted up at its edges. The hinges are first give in before image distortions turn up under selective pressure. In return, the display bezel yields evidently when pressure is applied and allows image deviations to become visible.

We like the metallic hinges that hardly teeter after adjusting the opening angle.(Dell Inspiron 1720 Battery ) Surprisingly, they don't cope well in shaky work conditions (train journey). Since they are smooth and the base unit is sufficiently heavy, both single-handed opening and closing are possible. The maximum opening angle of even a bit more than 100 degrees doesn't cause any restrictions in any case.

In addition to the clamshell design,( Battery Dell Vostro 1320 ) the ramshorn hook contributes to safety during transportation. It keeps the device securely closed and can be opened easily with the slider on the front edge.

Let's start with a tour around the device itself.( sony VGP-BPS13A/S battery ) We notice that the positioning favors right handed users a bit. Depending on the utilization of single ports, a few cables can gather on the left, which may considerably obstruct the work area on the laptop's left. Two of the five USB 2.0 ports, the display port, the VGA and the RJ45 are found on the left's center edge.

In opposition, ( Dell Vostro 1310 battery ) Lenovo has taken care to place potentially permanently occupied ports, such as the other two USB 2.0 ports and the eSATA/USB combo port, in the right's rear area in the interface arrangement. In addition, the right accommodates, from front to back, (dell vostro 1400 battery ) a 3.5mm combo audio socket, the optical drive in an Ultra Bay slot, a 4in1 cardreader that supports SD, MM, SDHC, SDXC, and an ExpressCard34 port.

The rear is completed by a powered USB 2.0 port and a RJ11 modem socket. ( Latitude D620 Battery ) The power adapter is also connected on the case's rear.

To our regret, Lenovo forgets, like Dell in its E6420,( Dell Laptop Battery ) to install a USB 3.0 port in the course of the refresh. Although the eSATA interface also bids a higher data transfer rate than USB 2.0, increasingly more external mass memories are being offered with USB 3.0 ports and eSATA is disappearing little by little from the market. In comparison to the competition, we also notice that Dell relies on the utilization of a HDMI port in the E6420 and thus accepts the according restrictions. In opposition, Lenovo remains resolute in installing a display port directly on the device.
