Case

Our test model can be considered the 14-inch variant of the ProBook 430 G3. For that reason, the look of the two models does not differ much. Despite its price, the case looks upscale. The frame surrounding the keyboard is made from aluminium and a contrast to the matte black display unit. Besides, it feels good to the touch thanks to many rounded corners and edges. Moreover, the build quality is very good for this price point. Although the display hinges are quite small, they appear stable; at least in our factory new model. In the smaller model of the first generation, the display bounced easily. It remains to be seen whether this will also happen in our bigger 440 G3 models after it has been used for a longer period.

The parts of the case are precisely connected. There aren’t uneven or bigger gaps.

The battery can be removed without tools on the underside. The case remains stable and it is possible to use the laptop without a battery. Maintenance is easy due to a big maintenance hatch. The low weight of 1.6 kg is a pro for mobile use.

Unfortunately, there are also weaknesses: For example, the lid can be easily depressed. Overall, HP used a soft and thin plastic at the display. In contrast, the base unit appears very stable.

Connectivity

loading failed!

The offered interfaces are standard for current notebooks. As is already known from other models of this series, only two of three USB ports are USB 3.0 ports. The interface layout makes all interfaces easily reachable. However, when using both USB-3.0 ports the plugs should not be too big, otherwise, one of the two interfaces will be blocked.

Communication

Network communication is possible in two ways in the HP ProBook 440 G3. It is possible with the RealTek Semiconductor RTL8168/8111 PCI-E module via cable, which allows a transfer rate of up to 1 Gbit. The second possibility is a wireless connection via Intel’s Dual Band Wireless-AC 3165 module. The Wi-Fi performance is rated at up to 433 Mbit/s. A test specified by the author simulates the actual transfer rates. An Apple iMac 21.5 Late 2013 is available as reference, which supports the IEEE-802.11 ac standard and also 1 Gbit Ethernet. A 5 GB file is sent via a hard drive connected to the network (FRITZ!Box 7490). After multiple downloads, the average is calculated. The two test devices are located next to each other and need to get through one floor and a beeline of 4 m to the router. Via Wi-Fi, our test model, as well as the Apple iMac, achieved about 34 MB/s. Via cable, the HP ProBook 440 G3 achieved 109 MB/s, but the Apple iMac only reached 83 MB/s.

Security

To make stealing the device more difficult, the test device features a Kensington security lock slot and a fingerprint reader. Another integrated security feature is TPM. Also, the manufacturer ensures the required security standard with its proprietary software. The preinstalled HP Client Security Software allows the user to encrypt hard drives for example. An HP BIOS Protection is included, too.

Accessories

The usual installation information is included. Compatible accessories can optionally be bought from the manufacturer’s website. For example, these include bags, input devices, drives, combination locks and services packages. A universal port replicator is available for 280 Euros (~$306). It offers another six USB ports, an Ethernet port, a microphone in, headphones out, and HDMI out.

Maintenance

As already mentioned in the case section: There is a maintenance hatch on the underside of the notebook. You can take it off with a single screw. To loosen it, you have to remove the screw’s cover first. It is easy to take off the hatch. Afterwards, it is possible to replace the hard drive, the Wi-Fi ac module, and the RAM. It is not possible to clean the fan. A look inside brings a surprise: there is a free M.2 slot for adding a drive.

The battery can be removed with a mechanical lock without screws. It is possible to use the notebook without battery.

Warranty

Only a one-year warranty is included. A warranty extension to three years including on-site service costs about 130 Euros (~$142). Moreover, you can add accidental damage protection for 260 Euros (~$284). HP’s most expensive Care package is called “HP 3-year 9×5 Next Coverage Day Call to Repair (80%) Notebook Only Service.” However, details about the included services are not listed. The prices for the warranty range from 410 Euros (~$449, 3 years) to 1310 Euros (~$1435, 5 years).

 

Input Devices

Keyboard

The keyboard, which feels very grippy to the touch and can convince overall, deserves praise. All keys are firm enough and hardly yield at the corners. The pressure experience is constant; the key travel is soft and quite short. Touch typists will get used to the keyboard quickly. The typing noise is dull and not disturbing.

The mid-placed arrow keys are especially narrow and small in many of today’s notebook keyboards. However, HP made them wider and, thus, easier to use.

To be able to type in the dark, a keyboard light with two levels has been integrated.

Touchpad

Unfortunately, the touchpad is still too small in the current model. With a size of 9.6 x 4.9 cm, it falls behind the competitors from Lenovo and Dell. The touchpad is responsive and recognizes inputs without problems. Also, gestures are possible on the small touchpad. Unfortunately, the input device has some issues at the corners, where movements are partly not recognized at all. It sometimes even did not react at all when touched gently. Overall, the input device does its job, but it cannot replace a connected mouse.

The mouse buttons have a soft stroke and only emit a quiet and dull clicking noise.

The first obvious difference to the already reviewed 13.3-inch model is the used display. The 14-inch display features a Full HD resolution of 1920×1080 pixels, now. As already known from ProBooks, HP uses a matte panel. Thus, close light sources and reflections do not disturb the user. Unfortunately, the display brightness is not up-to-date. With an average brightness of 215 cd/m², the test model performs far worse than the Dell Latitude 3450 (273 cd/m²) and the Acer TravelMate P645 (308 cd/m²). Also, it is a negative point that it is a TN type. The competition proves that a high-end IPS panel can also find its way into a cheap business notebook.

The test model’s white streaks on dark/black background (see image) are very unattractive. We could not find out whether this is a defect of our test model or even a problem of the display series.

* … smaller is better

 

The test model’s contrast is 492:1. It only seems quite normal due to the low brightness and is rather poor. A black value of 0.5 cd/m² is also quite high. As a result, black does not appear deep. Overall, HP could do better.

The display is slightly bluish without calibration. The CalMAN analysis reports a DeltaE shift of 9.36 in the grayscale. The ColorChecker also reports a high DeltaE value of 8.64. After calibration, the deviations are significantly smaller with 1.4 in the grayscale and 3.25 in the colours.

The colour coverage is about 59.1% of sRGB and about 37.8% of AdobeRGB. These values are mainly important for professional use. They are not sufficient for graphics designers.

Since the manufacturer incorporated a matte display, it can be used outdoors in the shade. Due to the low brightness, it cannot cope with direct sunlight. Those looking for a device for frequent outdoor use should, for example, take a closer look at the Dell Latitude 3450.

Display Response Times

Display response times show how fast the screen can change from one colour to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

   ↔    Response Time Black to White
27.6 ms … rise ↗ and fall ↘ combined ↗ 11.2 ms rise
↘ 16.4 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 58 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.1 ms).
   ↔    Response Time 50% Grey to 80% Grey
46 ms … rise ↗ and fall ↘ combined ↗ 24 ms rise
↘ 22 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 72 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (40 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession – a method called Pulse Width Modulation (PWM). This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM not detected
In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9448 (minimum: 43 – maximum: 142900) Hz was measured.

Another consequence of choosing a cheap TN panel is poor viewing-angle stability. Even small changes in the opening angle lead to big colour and brightness shifts. In contrast, viewing from the sides works fine.

Alike in the smaller ProBook 430 series, the opening angle is too small. Especially when used on the lap, it is a few degrees too small for allowing comfortable use of the notebook.

Our test model is armed for the office segment with a new Intel Core i5 processor, 4 GB of RAM (single-channel) and a 500 GB HDD. Smaller performance reserves for multimedia tasks are available. However, the laptop is only targeted at the business range. Those who want to spend about 300 Euros (~$329) more will get an Intel i7 processor and dual-channel RAM.

Unfortunately, none of the ProBook 440 G3 series models comes with an LTE/3G modem. A model with such a module can be selected from the smaller ProBook 430 series.

Processor

Constant clock rates in Cinebench
Constant clock rates in Cinebench

A new Intel Core i5-6200U from the current Skylake generation is used as a processor. Both cores clocked at 2.3 GHz. With Turbo Boost, the CPU reaches a clock rate of up to 2.8 GHz (2 cores: max. 2.7 GHz). The “U” in the name hints at the low power consumption of the processor. The manufacturer specifies a TDP of 15 W.

We want to determine the performance with Cinebench R15. Our test model achieves 294 points in the multi-core test. This result conforms to other notebooks’ results with the same CPU. During the test, the two cores always clocked at 2.7 GHz. The processor’s predecessor (Intel Core i5-5200U) is about 11% slower in the Dell Latitude 3450.
