It looks the same with the soccer game, Fifa 12. We have to use the lowest detail level and 800x600 pixels to render a slightly jerky 29 fps in a running game. The frame rates can even drop a lot more in replays under certain circumstances. ( Samsung R458 battery )

The last game we assess by using the built-in benchmark is the rally simulation, Dirt 3. As before, we also had to limit our demands on the image quality to a minimum so that we ultimately achieve 25.9 fps in 800x600 pixels and very low details. ( Samsung R458R battery )

The E-450 is thus only suitable for current games to an extent. More often than not, the low processor performance is limiting so that even a reduction of the resolution partly doesn't enable unrestricted playability. However, comparable notebooks like the HP 630 with Intel's P6200 do even worse. First the graphics unit from Sandy Bridge can outdo the small Fusion APU. ( Samsung R463 battery )

Netbook hardware in a spacious 15 inch case - a next to silent cooling shouldn't actually be a problem here. Unfortunately, HP has failed this goal more or less clearly.The fan in the Presario CQ57 runs constantly even during longer idle periods. The 32.3 dB (A) aren't at all annoyingly loud, but could have been a lot lower with a more cleverly devised fan. The hard disk also contributes to the noise level with its very audible access noise and pushes the noise up to 34.1 dB (A). ( Samsung R464 battery )

A change in fan speed couldn't be determined during practical load, for example in 3DMark 06. The previous quiet whirr turns into a very audible airflow that reaches up to 38.5 dB (A) when we start both Prime95 and Furmark in our stress test. ( Samsung R465 battery )

Thus, especially the fan that is permanently active even in idle remains to be criticized. The reason for this is found under the option "Fan Always On" in the BIOS. As soon as this is disabled, the Presario CQ57 runs almost silently depending on the load. However, this deviating setting in the manufacturer's default state of delivery is disregarded in our rating. ( Samsung R467 battery )

Thanks to its energy-efficient Fusion APU, the temperature development remains on a very low level. We measure between 19 and 24 degrees Celsius on both the top and bottom in idle. That only increases to 26 degrees Celsius selectively in load. The user won't burn his fingers even directly at the vent with a lukewarm 37 degrees Celsius. Thus, the Presario CQ57 can be used on the lap without hesitation. ( Samsung R468 battery )

The notebook's hardware also stays cool. The cores' temperatures of the E-450 climb from 43 up to 59 degrees Celsius during full load. Thus, sufficient reserves are available even for midsummer temperatures. The power adapter's temperature of between 29 and 39 degrees Celsius is just as remarkable. ( Samsung R470 battery )

Among the competitors, only the Lenovo G575 clearly falls behind because its E-350 processor showed first signs of throttling at a temperature of up to 99 degrees Celsius in the stress test. ( Samsung R478 battery )

HP promotes the installed Altec Lansing stereo speakers with a small sticker. ( Samsung R505 battery ) However, they don't stand out much from the competition. We suspect that the sound system used in the HP 630 / HP 635 models has been adopted without modifications. While the good maximum volume and clear sound in the high-frequency range can be praised, the bass range has little power. Speech convinces with good understandability, but sounds a bit tinny. Basically, the quality is acceptable for a low cost notebook, even if we would recommend connecting external speakers. That is only possible analog via the headphone out due to the lack of an HDMI port. ( Samsung R507 battery )

We've seen the low power consumption of AMD's E series in previously tested notebooks, such as the Lenovo G575. The Presario CQ57 isn't any different here and is content with low 7.3 to 10.4 watts in idle. The higher rate is especially significant for practical use. It is determined with an enabled WLAN connection and maximum screen brightness. HP's 630 with a Pentium P6200 processor consumed a bit more, whereby Intel's latest Sandy Bridge generation is on a par in this field. ( Samsung R510 battery )

The power consumption increases to 22.8 watts in 3DMark 06 and its peak is 28 watts in our stress test. Both rates are excellent and on a par with other ULV processors that have a similar TDP. Only the HP 635 is a bit better with a maximum of 20 watts, but it is equipped with the E-240 single core CPU. ( Samsung R517 battery )

The manufacturer delivers the notebook with a compact 65 watt power adapter, which almost seems too big in view of the low power consumption. Therefore, it's no problem to recharge the battery even during full load use. ( Samsung R518 battery )

Our test sample owes its remarkable runtimes to the lower power consumption. Even if the 47 Wh battery isn't particularly big, the Presario CQ57 manages far more than 7 hours away from an outlet in idle. Reading a text document is simulated in the BatteryEater Reader's test. Here, WLAN is disabled and the maximum energy saving options are selected. ( Samsung R519 battery )In practical use, the runtime is just as generous with 5 hours of surfing (screen brightness: 150 cd/m2). Movies can be played via the built-in DVD drive for almost 4 hours.

The battery is drained after about 2 hours when we enable "High Performance" in Windows' energy savings options and start BatteryEater's Classic test. Like in the other measurements, HP gives up a somewhat longer battery life because the notebook automatically shuts down at a charge level of 9 percent at the latest. In return, the battery's life expectation is increased because frequent deep discharging can damage the lithium ion battery permanently. ( Samsung R522 battery )

HP Presario CQ57We can conclude the verdict for HP's Compaq Presario CQ57 with the title of a bestseller from Johannes Mario Simmel - "It Doesn't Always Have to be Caviar". The affordable entry level device can score in many aspects that are frivolously wasted by other, frequently much more expensive notebooks, though it has a few weaknesses. ( Samsung R540 battery )

We'll start with the good workmanship: The case, known from other HP models, convinces with high stability, which only could be improved a bit in terms of the display. The keyboard's good typing experience and the touchpad's accuracy also deserve praise. ( Samsung R560 battery )

The Fusion APU E-450 from AMD is a curse and a blessing at the same time. The low power consumption of only 18 watts TDP is reflected in long battery runtimes and minimum heat development. Moreover, a few games can be rendered smoothly thanks to a comparatively strong graphics unit. The CPU's performance deficit is all the more vast and even noticeable in routine use compared to Intel's Pentium processors. ( Samsung R610 battery )

Thus, the Presario CQ57 would be ideal as an affordable office device with multimedia qualities that can occasionally be used remote from an outlet. Our overall rating of 76 percent may seem low, but considering the price of less than €330 the buyer gets impressive value for his money. Faster and better equipped notebooks, such as the HP 630, meanwhile also available with Sandy Bridge processors, cost a lot more with starting about €400. ( Samsung R700 battery )
