Who buys EliteBooks? Meanwhile, we”ve got a pretty good idea about that. We”ve recently had the HP ProBook 6540b WD690EA in review, which delimits the EliteBook series downwards. You might also say: If a ProBook doesn”t suffice, you”ll buy an EliteBook. The premium business models” price starts at about 1150 euro.
We”ve chosen one of the lowest priced EliteBooks. There are almost no limits towards the top because HP also places its workstations under the name "EliteBook" by adding "w". Our 14 inch 8440p is technically limited to the basics with a Core i5-520M and without a dedicated graphic card. A high-resolution display is just as absent as a UMTS module.
Which claims can the EliteBook starter keep upright? What does it do better than the already good ProBook 6540b WD690EA? Is the elite alternative worthwhile for the ambitioned consumer or can he instead buy a ProBook, partly available for a lot less money? Our detailed review will answer these questions.
If you are annoyed about connecting and disconnecting cables after business trips, you can buy the matching HP NZ223AA Advanced Docking Station (street price 240 euro). It”s the same docking solution as used for the ProBook-series. The 14 incher is attached to the docking port with its base plate. The station has almost all connections that the notebook has. Additionally, there is a parallel port (printer port, LPT, 25-pin). Naturally, the laptop is also recharged over the station. Upgrade fans will find an integrated SATA extension slot, e.g. for a hard disk, on the station.
But that”s not all yet. The so-called 12 cell battery with an extremely high capacity (AT486AA, 180 euro) can be attached to the device”s bottom (battery dock). The standard battery remains inserted during that. HP states an additional 10 hour operating time.
The brightness of the display, illuminated with LEDs, can be automatically set. The ambient light sensor in the lower TFT”s bezel is there for that. The sensor determines how bright the screen has to be lit up depending on the room”s brightness. This works quite well practically. The luminosity also goes up to maximum in sunlight via sensor. We disabled the ambient light sensor via FN+F11 for the measurements. We measured an average rate of 212 cd/m2. The illumination is very even with 90 percent; the brightest spot is 225 cd/m2.
The manufacturer is unnecessarily stingy with the RAM. There is only a 2048 MB DDR3 (PC3-10600) inserted to the mainboard. The memory configuration should first start at four gigabytes and not already at two in this upper price category. The two GBs are on one DDR3 bar under the base plate. It”s not accessible for the user, unless the entire cover is removed. Nevertheless, there is a RAM upgrade possibility. We found a single RAM slot underneath a small cover on the bottom.
The 520M Arrandale has two cores with 2.40 GHz native (standard clock rate). The real clock rate is between 2.40 and 2.93 GHz with assistance from Intel”s Turbo Boost. Single cores of the four (native + hyperthreading) are overclocked during processor-controlled overclocking. The feature hyperthreading complements both physical cores with two virtual ones. Thus, applications can access up to four threads. Naturally, turbo boost also affects the virtual cores. It should be mentioned that the initially stated maximum clock rate never is reached by all cores at the same time, but only is reached when the entire computing effort is executed by a single core.

The experienced computer performance isn”t only dependent on the processor. It”s an interaction of CPU, graphics (IGP in this case), RAM and hard disk, which makes the 8440p to a strong office notebook. We”ve checked the application performance with PCMark Vantage. Its total result of 5770 points indicates a strong system in comparison. Laptops with a Core i7 720QM or 820QM have more performance. Dedicated graphics wouldn”t increase the Vantage rate dramatically. Thus, Samsung”s R780-Hero achieves 6026 points with the same 520M processor and Nvidia GT 330M.
Recently reviewed business laptops don”t score much better in comparison: Fujitsu”s Lifebook S760 (620M, Intel HD: 6.178); Lenovo”s ThinkPad W510 (820QM, FX880M: 5.857); Sony”s Vaio VPC-F11Z1/E (720QM, GT330M: 5.844); Fujitsu”s Lifebook T900 (520M, Intel HD: 5.591). The recently tested HP ProBook 6540bWD690EA (430M), with a similarly fast hard disk and dedicated ATI HD4550 also only achieved 5158 Vantage points.
Short: The i5-520M CPU in the EliteBook 8440p-WJ681AW supplies a high computing rate that is comparable with previous high-end models of the Core 2 Duo generation. The turbo boost function provides high-performance in every application, no matter if with or without a multi-core use.

The fast 7200 rpm hard disk from Seagate (ST9250410AS) is noticeable with its 250 GB. The HDD reads faster than average with 78.3 MB/s in sequential read. The hard disk is only audible with a consistent basic noise during use. However, the desktop also unfortunately hums because of the 2.5 inch HDD”s rotation speed. This isn”t necessarily disturbing. The noise can be eliminated by placing the base feet on a soft surface. Readers might know this phenomenon from fast rotating, external hard disks.

No matter what we did in the test, the surface temperatures simply didn”t increase. We didn”t even manage to increase the waste air temperature on the surface over 33 degrees Celsius selectively after a stress test of several hours. We measured this maximum temperature in the power button”s area. The case doesn”t get warmer than 32 degrees even in the vent”s vicinity. Those are remarkably low temperatures for a stress test.
It can only get better when there”s nothing to do. And in fact: After two hours in standstill idle, the previously warmest spot near the power button is only 24 degrees warm. The base plate no longer exceeds 27 degrees. Let”s look at the temperature sensors on the processor: It shows 40 degrees on the CPU in idle. It doesn”t get more than 69 degrees under 100 percent stress (35 watt TDP). The cooling system works exemplary.
The manufacturer cites "integrated stereo loudspeakers". We couldn”t find one of the two loudspeakers at first because the sound escaped from the case”s bottom. The assumption of a mono loudspeaker proved to be wrong. The stereo loudspeakers are placed on the front in the area of the release button.
The loudspeaker”s sound emphasizes the midranges and lacks all bass. The sound picture is a bit dull but is at least very loud and clear enough to fill a presentation with sound. We notice a exceptionally strong output level when external speakers are connected to the 3.5 mm audio-out. Thus, external loudspeaker can be used without noise.

The EliteBook 8440p, in our configuration variant, passed the EnergyStarclassification. No wonder, because the (lowest) idle power consumption is less than 10 watts, despite the high CPU performance. This applies when all energy savings options are exhausted and the luminosity gleams at its lowest level. Seen realistically, the energy requirement without battery charging in an undemanding use (WLAN, surfing, office, emails) will be just about 20 watts. Merely CULV or a few Core 2 Duo notebooks could proclaim such a low idle power consumption until now. One exception is the highly optimized for energy Sony Vaio VPC-Z11X9E/B(520M, GT330M) with 6.2 watts in idle (minimum).
When CPU and GPU are at work, the power requirement naturally increases. Whilst 3DMark2006 is being worked on via the IGP graphics in the CPU, 47 watts are consumed. The multimeter displays 50.7 watts in the stress test with Prime95 and Furmark. The 65 watt adapter is just sufficient for the power consumption. The effective power is 65.7 watts in the stress test including battery charging. The little adapter already gets very warm with 56 watts in this case.
