Although the part of the top cover is made of plastic material and have the shedding this feature not still in terms of hardness showed a higher level, the actual test his suitability pressure fingers only appear smaller magnitude drop Shen, indicating that the aircraft roof have a certain resistance to stress. The screen frame part of the B side of the aircraft using the common class piano processing characteristics of the screen frame to use this type of approach has a beautiful but also easily contaminated with fingerprints.

The effective utilization of proceeds of C surface space, 14 laptop keyboard layout program, with more than 90% of the full-size keys back to power moderate, user fatigue is not easy in a long time operation. Total aircraft the interface provides a USB 2.0 interface, two USB3.0 ports, one eSATA (USB2.0 multiplexing) interface, an HDMI interface, a VGA port, an RJ-45 (cable) interface, an audio output jack, a microphone input jack, as well as more than one card reader. From the point of view of practical application, these interfaces, regardless of the type or number, are sufficient in practical applications to meet the needs of most users daily use.


Due to 3520 and N5720 with 48Wh DELL Inspiron N5720 Battery similar, 3520 in the thickness and weight, and the N5720 is not much difference, however, has a small difference adapter. Since the N5720 i7-3820QM processor maximum TDP of 45W the NVIDIA Quadro K2000M largest TDP compared to 55W, which both add up to TDP has reached 100W, so as to ensure the performance of the machine to be able to do the biggest play, Inspiron N5720 is equipped with a a power of 170W adapter, it's The volume also basically the equivalent of two 3520 90W adapter.
