To prevent cable chaos there are interfaces at the backProfessionals and demanding users generally value the selection of ports very highly. The 14 inch notebook has everything on board that we would expect from a work notebook, without providing as many as a precision workstation would have. acer aspire 5100 battery
These include a screw tight VGA port, a PC-Card (PCMCIA) shaft, and FireWire.Compaq 301956-001 The older PC-Card standard, which has already gone out of fashion in the consumer world years ago (replaced by ExpressCard), is still popular in the business world. Using this special extension cards (mainly controllers) can be attached. The connection for fast external hard drives is also on board as eSATA, although there is no USB 3.0.Compaq 303175-B25
The interface selection on the left side consists of a Kensington-Lock,Compaq 247050-001 FireWire, HDMI, eSATA/USB, 1xUSB 2.0, PC-Card (PCMCIA), and card reader tightly packed together. If many cables are connected at the same time, these would cover a large area. The special Docking solution for the Latitude comes in handy for this scenario though. The E-Port Docking station for the E5400 and E5410 series are compatible with the E5420.Compaq 116314-001
As a real deal business notebook the Latitude E5420 can offer everything that can be wished for when it comes to communication technologies. Since we opted for the Basic-Version, the tested device contains neither Bluetooth or an HSDPA module. The corresponding mini PCIe slots (2x) next to the antenna and the SimCard slot are of course available.Compaq 291694
As far as wireless technology goes, the E5420 provides WLAN. The WLAN card uses the 802.11 b/g/n standards. Further to this the Broadcom NetXtreme 57xx Gigabit controller is also on board.Compaq 229783-001
Business notebooks are subjected to a requirement for good security features. While the bigger organisations usually have their own security solutions, smaller establishments are usually happy to have security features and software included with a notebook. Worth mentioning in this respect is the Dell Data Protection Tool, and the backup and restore manager.Compaq 232633-001
Business characteristics, such as Trusted Platform Module, or fingerprint reader, are not acquainted with the E5420. Merely the Kensington Security slot can be used as a preventative measure against theft with a suitable cable.Compaq 250848-B25
For the important protection against the theft of data, Compaq 146252-B25 the software package Worry-Free Business Security Services (Trendmicro) is included. The price for the licence: 60 Euros. This solution, which is tailored towards small businesses without their own IT department, is supposed to protect against viruses, hacker, spam, spyware, phishing, and theft of data. Via the web-based console, the Latitude for an employee can be administrated from anywhere (Remote Manager).Compaq 293343-B25
To praise: Windows 7 Home Premium 32-bit is contained on a DVD. The user therefore doesn't have to create recovery discs, as is usually the case with other manufacturers.Compaq 182281-001
The standard warranty upon delivery has a duration of 12 months. For an additional sum it is however possible to attain upgrades from Dell, e.g. 3 years Pro Support with next working day on-site repair.Compaq 134110-B21
The keys with a crisp pressure point and a long key travel give a very good feedback. The separated arrow keys (+ page up/down) stand out from the keyboard, and can definitely be operated without looking. Compaq 346970-001
An alphanumeric keypad is out of the question due to the form factor of the device. Users have the opportunity to use this via key conversion using the Fn keys. The corresponding numbers and calculation symbols are marked in red on the letter keys.Compaq 346970-001
The base of the keys of the Latitude E5420 is generally firm, and provides the user with a firm end stop (not hard). The keys are pleasantly grippy. Merely the keys above the optical drive (;, ', [) are a little bouncy when pushing them hard.Compaq 367759-001
The use of the touchpad made a good impression on us in every respect. The quietness, and its large size, as well as easy to use buttons are worlds better than the majority of consumer touchpads. The surface is pleasantly smooth but not slippery.Compaq PM579A
The Alps multi-touchpad is sufficiently dimensioned with a 9.1 centimeter diameter. It is sensitive right up to the edges. The touchpad only has a vertical scroll bar, which isn't marked though.HP HSTNN-IB45
The non-reflective LED panel (type: Samsung LTN156AT02P01) has a resolution of 1366 x 768 pixels with an aspect ratio of 16:9. HP HSTNN-DB02 The WXGA resolution is the standard for 14 and 13 inch notebooks. The measured black level lies at 1.42 cd/m², which comes with a very bad contrast of 131:1. Blacks are therefore not very dark, but have more of a gray glimmer.HP 371916-001
