elitebook 840 g4 lcd touch screen free sample

If you haven"t been trained, qualified and authorized, then you rendered your HP warranty void. No certified HP repair facility will assist you free of charge in that state of your notebook. Don"t know if you"re able to restore that HP warranty by reverting back to original state. And you"ll want to ask such facilities if they accept orders to transform model to a different one. The touch screen variant of your model name will have a different model number. Not all certified facilities are trained nor accepting such changes.

If you aren"t qualified and accept the loss of your HP warranty, then follow the service manuals instructions. As far as I understood, you didn"t order all the replacement parts needed, especially the cable kit mentioned in the service manual of the display replacement section? If I remember correctly, changing of non-touch display to touch display needs different cable wiring. But I"m not a trained nor qualified HP service technician and hence can"t provide authoritive answers.

So why do you follow your believe instead of the HP training? As mentioned above, it seems that a cable for touch feature is included in the cable kit specified in the service manual. Don"t have such a cable kit to check.

The EliteBooks from the 800-series are premium business notebooks from HP. There are two more expensive EliteBooks with the additional Folio designation (1040, G1), but they have a bigger focus on mobility. The EliteBook 840 with its 14-inch display is already the fourth generation (G4), but there are only minor changes compared to the previous EliteBook 840 G3. More precisely: You only get a new processor from Intel"s current Kaby Lake generation.

Our test model carries the designation Z2V49ET ABD and is a mainstream model from the 840 G4 lineup when you have a look at the available components. HP equips the test model with an Intel Core i5, 8 GB RAM, a 256 GB NVM-SSD as well as a Full HD display. The latter is unfortunately not an IPS screen but is based on TN technology, which was already the case for the previous model.

The elegant case of the EliteBook 840 G4 did not change this year. HP once again uses a combination of magnesium alloy and painted aluminum, only the bottom is made of dark plastic. The palm rests are therefore cool to touch and fingerprints are no problem. We really like the design with the mixture of black and silver. The lid has a silver HP logo, but there are otherwise no design elements. HP uses a visual trick, because the chassis gets a bit slimmer towards the front, so the laptop itself appears thinner than it actually is.

The stability of the base unit is also good and only a lot of pressure can warp the surfaces, which also results in slight creaking sounds. The thin lid is not as stable and can easily be twisted. Pressure from behind will also create ripples on the screen. The hinges have black plastic covers and are smooth, but they have some play and the display will quickly bounce. The maximum opening angle is sufficient at ~145 degrees. We can hear some creaking from the hinges when we adjust the angle, but it is not as bad compared to some shown in user videos on the Internet. Obviously we cannot check the long-term effects during our short review period.

This is the second model year with the same chassis, but it still holds up very well in our size comparison. The footprint is very similar between all comparison devices. This is also the case for the height, except for the noticeably slimmer EliteBook Folio 1040 G3. At ~1.9 cm and a weight of around 1.5 kg, the 14-inch laptop is very portable and can easily be stored in a bag or backpack.

The ports did not change compared to the previous model. The EliteBook 840 G3 was already equipped with a modern USB-C jack, but it is still just a "regular" USB 3.1 port without support for Thunderbolt, DisplayPort, or power supply. At least you get all the other important components including two video outputs (DisplayPort 1.2, VGA) as well as a docking port. These connectors are very important for office environments.

The new EliteBook 840 G4 once again offers all relevant security features. This includes the fingerprint scanner (swipe-style), TPM, SmartCard reader, and a slot for a Kensington lock, for example. But HP also implements numerous software tools and features to increase the security of the laptop. This includes HP SureStat or HP Client Security, where many security-relevant settings (administration of passwords, fingerprints, hard drive encryption) are summarized. The EliteBook 840 G4 is also equipped with a vibration sensor, but it is only important for SKUs with mechanical hard drives.

HP grants a limited three-year warranty for the EliteBook 840 G4, which can be extended or expanded, respectively, by optional CarePacks. An upgrade to a five-year on-site service, for example, retails for around 350 Euros (~$376).

The touchpad is equipped with dedicated mouse buttons, but they are not perfectly integrated and clatter a bit. The clicking sounds do not leave the most sophisticated impression, either. The touchpad surface itself is not very large at 10 x 5.5 cm due to the dedicated buttons, but the handling is very good thanks to the smooth surface. Gestures are also executed well.

HP offers many displays for the EliteBook 840 G4, and the two matte IPS models (1920x1080 or 2560x1440 pixels) are particularly interesting. Similar to the previous test model of the EliteBook 840, however, we are once again dealing with the FHD-TN panel. The TN technology is indicated by SVA (Standard Viewing Angle) in spec sheets from HP. There is a worse option with the HD TN panel, but the FHD screen is not particularly satisfying, either.

Our calibration improves the situation for the colors and the grayscale significantly. The strong blue cast is gone as well, so you should definitely calibrate the screen or use our icc-profile, which is linked in the box above.

ℹDisplay response times show how fast the screen is able to change from one color 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

ℹTo 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

The outdoor capabilities of the EliteBook are decent thanks to the matte screen surface. The luminance is not reduced on battery power, either, so you can also use the test model in bright environments.

HP offers several components for the EliteBook 840 G4. You can choose between modern Kaby Lake ULV processors, starting with the Core i3-7100U all the way up to the Core i7-7600U. All SKUs use the integrated GPU, because dedicated graphics cards are not available. The two SODIMM memory slots support up to 32 GB DDR4-RAM. Storage options include conventional 2.5-inch HDDs as well as M.2 SSDs (SATA-III & PCIe), so the subjective system performance can differ significantly depending on the configuration.

Our test model of the EliteBook 840 G4 is equipped with the mainstream CPU option, the Core i5-7200U. The dual-core chip has a base frequency of 2.5 GHz, which can be raised all the way up to 3.1 GHz via Turbo Boost (also for two active cores). Hyper-Threading is supported as well, so the two cores can execute up to four threads simultaneously. The performance is more than sufficient for common office tasks.

The system performance of our test model definitely benefits from the fast PCIe-SSD. Inputs are executed immediately and applications are launched without delays. The overall hardware configuration is very balanced and there are no bottlenecks. All comparison devices are very close to each other and the EliteBook 840 G4 manages average scores in the synthetic PCMark 8 benchmarks. It would be possible to increase the scores a bit with a faster processor and more RAM, but you will hardly notice the difference in practice.

The EliteBook 840 G4 is either equipped with conventional 2.5-inch HDDs or M.2-2280 SSDs. Our test model is shipped with the Samsung PM961 with a storage capacity of 256 GB. The NVMe drive is attached via PCIe and is currently used for many high-end business notebooks. The benchmark results are very good and the sequential transfer rates in particular are superior to SATA-III drives. More benchmarks for many HDDs & SSDs are listed in our comprehensive comparison.

We already mentioned that the EliteBook 840 G4 is not available with dedicated graphics cards. All the graphics calculations are handled by the integrated Intel HD Graphics 620 of the processor. The maximum core clock can vary depending on the CPU model; our GPU can reach up to 1000 MHz.

It is no surprise that the performance of the integrated GPU is not sufficient for modern games. You are also limited to low details and resolutions for older titles like BioShock Infinite, for example. A second RAM module could increase the fps number by a couple of percent, but this will obviously not transform the EliteBook 840 G4 into a gaming laptop. Our gaming list shows what games can be played with the integrated HD 620.

The HP EliteBook 840 G4 is a very quiet laptop. The fan is deactivated while idling or with light workloads and we cannot hear any annoying sounds, either. This is obviously not the case for SKUs with mechanical hard drives.

There are no surprises in our consumption measurements, and the test model is even among the most efficient laptops within the comparison group. The load measurements easily show what devices are bound by the usual TDP limit, because they will hover around 30-32 Watts. Our EliteBook 840 G4 is such a device. The compact 45-Watt power adapter is sufficient for the maximum consumption.

The new HP EliteBook 840 G4 is basically just a Kaby Lake update of the previous G3 model. Both the size and the quality of the case still hold up well against the competition, only some issues like the creaking hinges or the clattery dedicated touchpad buttons affect the good impression a bit. The access to the components is another positive aspect: Upgrading the RAM is no problem, for example. We still really like the input devices – the keyboard in particular.

The 14-inch business laptop does not disappoint in terms of performance or emissions, either. The laptop is quiet, does not get overly warm, and the Intel Core i5-7200U can utilize its performance potential really well. HP also increased the battery capacity, which results in practical runtimes of almost 10 hours.Good chassis, sufficient performance, low emissions – the fourth generation of the HP EliteBook 840 could be a very good business laptop. This is prevented by the bad TN panel, which has no place in a laptop for more than 1,500 Euros (~$1614).

That HP only slightly updated the EliteBook this year is made evident with the ports. You get all the important connectors for the office, but there is no future-proof Thunderbolt 3.

The biggest problem, however, is the Full HD TN display. Luminance and resolution are okay, but the panel disappoints in pretty much all the other measurements. The limited viewing-angle stability is a real issue in practice. Such a panel should not be used in a business laptop for more than 1,500 Euros (~$1614). If you are interested in the EliteBook 840, you should definitely get an IPS model. We cannot recommend our test sample with the TN screen.
