HP PROBOOK 640 DRIVER DOWNLOAD






















Operating System: Microsoft Windows 10 bit. Is there someone from HP who could help in solving this issue? Thank you in advance. Reb Solved! Tags 6. Tags: Category: Driver. Reply I have the same question. Accepted Solutions. Level Message 5 of Hi, rkaro Did you read the release notes for the driver you installed? It tells you what version of Windows 10 the driver is supported on and v isn't one of them.

Tags 2. Tags: HP Probook G8. Yes No. Message 2 of Hi, Just wondering why you are still using the edition since it is at end of servicing since May Regards, David. Was this reply helpful? Message 3 of Compared with current ThinkPads, the ProBook also offers a somewhat shorter drop - whether this is positive or negative remains to be a matter of taste. The TrackPoint popular among many users is again reserved for the higher-priced EliteBook series. This shortcoming can be ignored easily thanks to the good gliding properties, impeccable accuracy, and its high responsiveness to multitouch gestures, and an external mouse will not inevitably be needed.

We would also like to highlight both dedicated mouse keys that, with their clearly defined pressure point, are much more reliable than the fully integrated ClickPad solutions in some rivals. Alongside a screen diagonal of exactly Users with normal eyesight should be able to recognize fine fonts and symbols well without increasing the scaling factor.

Besides the higher resolution, the Full HD panel also promises a stronger backlight. A small minus point is only found in the screen's PWM control Hz, all brightness levels below maximum. This can cause headaches or dizziness in very sensitive users - the devices from Lenovo, Dell and Toshiba at least did not exhibit this issue in the tested configurations. The black level 0. First a look at the screen's color reproduction: The panel displays a massive bluish tint and a correspondingly high DeltaE shift in delivery state.

Calibrating improves the reproduction tremendously and the average DeltaE rates drop to an outstanding 1. In particular, the Latitude E is weak here. However, it is offered with a much brighter IPS panel for a surcharge. There should be no flickering or PWM above this brightness setting.

The frequency of Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below. If PWM was detected, an average of minimum: 5 - maximum: Hz was measured. Finally, we will look at the G2's biggest points of criticism: The insufficient viewing-angle stability. The aforementioned contrast and color accuracy rates are only valid when looking at the screen from an absolutely straight angle.

The slightest shifts drastically distort the image impression. If HP used an IPS panel like other manufacturers, then this problem would be considerably less prominent - and the user would not have to permanently adjust the tilting angle according to the present seating position.

Slowly but surely, Intel's new Kaby Lake generation casts its shadow ahead - the first scions could already be presented as early as September. Until then, customers and manufacturers will have to be satisfied with the current Skylake product range.

HP opted for the popular Core iU mid-range model. Its two cores clock at 2. The performance can even compete with some dedicated, low-end accelerators depending on the memory configuration.

However, the manufacturer only installs a DDR module with a capacity of 8 GB ex-factory, which lowers the graphics performance slightly as a consequence of the resulting single-channel interface. A GB M. The ProBook does not have problems utilizing the Core iU's full Turbo Boost headroom and not only thanks to its bulky casing. A stable 2. The performance is correspondingly good. Although these differences are measurable, they are hardly noticed in routine use.

HP has made a reasonable decision with the U from a price-performance point of view. The PM M. In return, the PM has a slight lead on its rivals when dealing with smaller 4K files and multi-parallel accesses. Samsung's SSDs also have the reputation of being particularly reliable - thus, we can again congratulate Samsung for making a good decision in terms of components.

The laptop gives a superb performance even without a pricey i7 chip and proves to be a powerful and responsive office device. Therefore, the minor lag in PCMark compared with mostly better equipped and more expensive rivals should not be overrated. Expanding the working memory with a second 8 GB module could at most be considered when extreme multitasking is routine. That would also activate dual-channel mode, which would boost the graphics performance.

Very performance-centered users should take a closer look at the Latitude 14 E that is the only laptop in this category that principally carries quad-core CPUs from the standard voltage division. However, Dell does not offer corresponding configurations everywhere. Nevertheless, its reserves are absolutely sufficient for normal desktop use, multimedia purposes, and even small CAD projects. Considering the extremely limited 3D performance, G2 buyers will not have much fun playing up-to-date games.

Although some undemanding games, such as Dirt Rally , run smoothly in very low settings, a firework display of graphics should not be expected - but that is not the claim of a laptop primarily designed for office applications anyway. Unfortunately, the fan in our review sample rarely stops spinning completely even during prolonged idle periods, which prevents an absolute noiseless operation. However, the resulting noise level of just below 30 dB A would not really be noticed during routine use if it were not for an occasional speed fluctuation - HP should certainly take care of that.

Basically, the cooling system seems well-designed as the very low load noise development proves: Despite the slow-spinning fan, the G2 never gets exceedingly warm. The manufacturer also has the temperatures under control.

The fact that the clock rates dropped to approximately 1. The stereo speakers in the ProBook are hidden behind a grille above the keyboard. While we can call both the maximum volume and high tone playback good, the speakers completely fail in the mid and low tone ranges.

The amplitude frequency response decreases quickly already below roughly - Hz - Dell has definitely done a better job in its Latitude E The provided output is, however, certainly enough for system sounds and speech. Music or videos are only really enjoyable with external speakers, though. They can be connected via the 3.

With 3. Most office laptops permanently settle to a maximum consumption of 30 watts when throttling sets in due to the ULV chips' watt limit - smaller differences only result from factors like screen brightness, panel, and memory configuration. Solely the ThinkPad L , being the only device with a dedicated graphics card, steps out of line in this comparison. Check now.
